NEOS S&P 500(R) High Income ETF | Active Management Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Active Management Risk. The Fund is actively managed, which means that investment decisions are made based on investment views. There is no guarantee that the investment views will produce the desired results or expected returns, which may cause the Fund to fail to meet its investment objective or to underperform its benchmark index or funds with similar investment objectives and strategies. Furthermore, active trading that can accompany active management may result in high portfolio turnover, which may have a negative impact on performance. Active trading may result in higher brokerage costs or mark-up charges, which are ultimately passed on to shareholders of the Fund. Active trading may also result in adverse tax consequences.

 

NEOS S&P 500(R) High Income ETF | Concentration Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Concentration Risk. The Fund may invest in up to 100% of the constituents of the S&P 500®, which itself may have concentration in certain regions, economies, countries, markets, industries or sectors. The Fund may be susceptible to an increased risk of loss, including losses due to adverse events that affect the Fund’s investments more than the market as a whole, to the extent that the Fund’s investments are concentrated in the securities of a particular issuer or issuers, country, group of countries, region, market, industry, group of industries, sector or asset class.

 

NEOS S&P 500(R) High Income ETF | Covered Call Option Writing Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Covered Call Option Writing Risk. By writing covered call options, in return for the receipt of premiums, the Fund will give up the opportunity to benefit from potential increases in the value of the S&P 500® above the exercise prices of such options, but will continue to bear the risk of declines in the value of the S&P 500®. The premiums received from the options may not be sufficient to offset any losses sustained from the volatility of the underlying stocks over time. In addition, the Fund’s ability to sell the securities underlying the options will be limited while the options are in effect unless the Fund cancels out the option positions through the purchase of offsetting identical options prior to the expiration of the written options. Exchanges may suspend the trading of options in volatile markets. If trading is suspended, the Fund may be unable to write options at times that may be desirable or advantageous to do so, which may increase the risk of tracking error.

 

NEOS S&P 500(R) High Income ETF | Derivatives Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Derivatives Risk. The Fund’s use of derivatives may reduce the Fund’s returns or increase volatility. Volatility is defined as the characteristic of a security, an index or a market to fluctuate significantly in price within a short time period. Derivatives may also be subject to counterparty risk, which is the risk that the other party in the transaction will not fulfill its contractual obligation. Counterparty risk for over-the-counter (“OTC”) derivatives is generally higher than that for derivatives traded on an exchange or through a clearing house. A risk of the Fund’s use of derivatives is that the fluctuations in their values may not correlate perfectly with the value of the underlying asset, the performance of the asset class to which the Fund seeks exposure or the performance of the overall markets. The possible lack of a liquid secondary market for derivatives and the resulting inability of the Fund to sell or otherwise close a derivatives position could expose the Fund to losses and could make derivatives more difficult for the Fund to value accurately. The Fund could also suffer losses related to its derivatives positions as a result of unanticipated market movements, or movements between the time of periodic reallocations of Fund assets, which losses are potentially unlimited. Certain derivatives may give rise to a form of leverage and may expose the Fund to greater risk and increase its costs. The impact of U.S. and global regulation of derivatives may make derivatives more costly, may limit the availability of derivatives, may delay or restrict the exercise by the Fund of termination rights or remedies upon a counterparty default under derivatives held by the Fund (which could result in losses), or may otherwise adversely affect the value or performance of derivatives.

 

NEOS S&P 500(R) High Income ETF | Equity Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Equity Risk. The net asset value of the Fund will fluctuate based on changes in the value of the U.S. equity securities held by the Fund. Equity prices can fall rapidly in response to developments affecting a specific company or industry, or to changing economic, political or market conditions.

 

NEOS S&P 500(R) High Income ETF | Exchange Traded Funds (“ETFs”) Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Exchange Traded Funds (“ETFs”) Risk. The Fund is structured as an ETF. As a result, the Fund is subject to special risks, including:

 

NEOS S&P 500(R) High Income ETF | Not Individually Redeemable [Member]  
Prospectus [Line Items]  
Risk [Text Block]
●Not Individually Redeemable. The Fund’s shares (“Shares”) are not redeemable by retail investors and may be redeemed only by Authorized Participants at net asset value (“NAV”) and only in Creation Units. A retail investor generally incurs brokerage costs when selling shares.

 

NEOS S&P 500(R) High Income ETF | Trading Issues [Member]  
Prospectus [Line Items]  
Risk [Text Block]
●Trading Issues. Trading in Shares on the Exchange may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in Shares inadvisable, such as extraordinary market volatility. There can be no assurance that Shares will continue to meet the listing requirements of the Exchange which may result in the Shares being delisted. An active trading market for the Shares may not be developed or maintained. If the Shares are traded outside a collateralized settlement system, the number of financial institutions that can act as Authorized Participants that can post collateral on an agency basis is limited, which may limit the market for the Shares.

 

NEOS S&P 500(R) High Income ETF | Market Price Variance Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]
●Market Price Variance Risk. The market prices of Shares will fluctuate in response to changes in NAV and supply and demand for Shares and will include a “bid-ask spread” charged by the exchange specialists, market makers or other participants that trade the Shares. There may be times when the market price and the NAV vary significantly. This means that Shares may trade at a discount to NAV.

 

○In times of market stress, market makers may step away from their role market making in the Shares and in executing trades, which can lead to differences between the market value of the Shares and the Fund’s NAV.

 

○The market price of the Shares may deviate from the Fund’s NAV, particularly during times of market stress, with the result that investors may pay significantly more or significantly less for the Shares than the Fund’s NAV, which is reflected in the bid and ask price for the Shares or in the closing price.

 

○In stressed market conditions, the market for the Shares may become less liquid in response to the deteriorating liquidity of the Fund’s portfolio. This adverse effect on the liquidity of the Shares may, in turn, lead to differences between the market value of the Shares and the Fund’s NAV.

 

NEOS S&P 500(R) High Income ETF | Authorized Participant Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]
●Authorized Participant Risk. Only an Authorized Participant may engage in creation or redemption transactions directly with the Fund. The Fund has a limited number of institutions that may act as an Authorized Participant on an agency basis (i.e., on behalf of other market participants). To the extent that Authorized Participants exit the business or are unable to proceed with creation or redemption orders with respect to the Fund and no other Authorized Participant is able to step forward to create or redeem Creation Units, Fund shares may be more likely to trade at a premium or discount to net asset value and possibly face trading halts or delisting. Authorized Participant concentration risk may be heightened for securities or instruments that have lower trading volumes.

 

Additionally, purchases and redemptions of creation units primarily with cash rather than through in-kind delivery of portfolio securities may cause the Fund to incur certain costs, including brokerage costs or taxable gains or losses that it might not have incurred if it made a redemption in-kind, and therefore decrease the Fund’s NAV to the extent not offset by a transaction fee payable by an AP.

 

NEOS S&P 500(R) High Income ETF | Issuer Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Issuer Risk. Changes in the financial condition or credit rating of an issuer or counterparty, changes in specific economic or political conditions that affect a particular type of security or issuer, and changes in general economic or political conditions can affect a security’s or instrument’s value. The values of securities of smaller, less well-known issuers can be more volatile than those of larger issuers. Issuer-specific events can have a negative impact on the value of the Fund.

 

NEOS S&P 500(R) High Income ETF | Market and Geopolitical Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Market and Geopolitical Risk. The increasing interconnectivity between global economies and financial markets increases the likelihood that events or conditions in one region or financial market may adversely impact issuers in a different country, region or financial market. Securities in the Fund’s portfolio may underperform due to inflation (or expectations for inflation), interest rates, global demand for particular products or resources, natural disasters, climate change and climate-related events, pandemics, epidemics, terrorism, regulatory events and governmental or quasi-governmental actions. The occurrence of global events similar to those in recent years may result in market volatility and may have long term effects on both the U.S. and global financial markets.

 

NEOS S&P 500(R) High Income ETF | Options Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Options Risk. There are risks associated with the sale and purchase of call and put options. As a seller (writer) of a put option, the Fund will tend to lose money if the value of the reference index or security falls below the strike price. As the seller (writer) of a call option, the Fund will tend to lose money if the value of the reference index or security rises above the strike price. As the buyer of a put or call option, the Fund risks losing the entire premium invested in the option if the Fund does not exercise the option.

 

NEOS S&P 500(R) High Income ETF | Sector Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Sector Risk. Sector risk is the possibility that securities within the same group of industries will decline in price due to sector-specific market or economic developments. If the Fund invests more heavily in a particular sector, the value of its shares may be especially sensitive to factors and economic risks that specifically affect that sector. As a result, the Fund’s share price may fluctuate more widely than the value of shares of a fund that invests in a broader range of industries.

 

NEOS S&P 500(R) High Income ETF | Information Technology Sector Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Information Technology Sector Risk. Because the S&P 500® Index has been concentrated in the information technology sector, the Fund may be sensitive to changes in, and its performance may depend to a greater extent on, the overall condition of the information technology sector. Information technology companies face intense competition, both domestically and internationally, which may have an adverse effect on profit margins. Information technology companies may have limited product lines, markets, financial resources or personnel. The products of information technology companies may face product obsolescence due to rapid technological developments and frequent new product introduction, unpredictable changes in growth rates and competition for the services of qualified personnel. Companies in the information technology sector are heavily dependent on patent protection and the expiration of patents may adversely affect the profitability of these companies.

 

NEOS S&P 500(R) High Income ETF | Tax Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Tax Risk. The Fund invests in derivatives. The federal income tax treatment of a derivative may not be as favorable as a direct investment in an underlying asset. Derivatives may produce taxable income and taxable realized gain. Derivatives may adversely affect the timing, character and amount of income the Fund realizes from its investments. As a result, a larger portion of the Fund’s distributions may be treated as ordinary income rather than as capital gains. In addition, certain derivatives are subject to mark-to-market or straddle provisions of the Internal Revenue Code of 1986, as amended (the “Internal Revenue Code”). If such provisions are applicable, there could be an increase (or decrease) in the amount of taxable dividends paid by the Fund.

 

NEOS S&P 500(R) High Income ETF | Valuation Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Valuation Risk. The price the Fund could receive upon the sale of a security or other asset may differ from the Fund’s valuation of the security or other asset and from the value used by the Reference Index, particularly for securities or other assets that trade in low volume or volatile markets or that are valued using a fair value methodology as a result of trade suspensions or for other reasons. In addition, the value of the securities or other assets in the Fund’s portfolio may change on days or during time periods when shareholders will not be able to purchase or sell the Fund’s shares. Authorized Participants who purchase or redeem Fund shares on days when the Fund is holding fair-valued securities may receive fewer or more shares, or lower or higher redemption proceeds, than they would have received had the Fund not fair-valued securities or used a different valuation methodology. The Fund’s ability to value investments may be impacted by technological issues or errors by pricing services or other third- party service providers.

NEOS Enhanced Income Aggregate Bond ETF | Credit Risk [Member]

Credit Risk. Debt issuers and other counterparties may be unable or unwilling to make timely interest and/or principal payments when due or otherwise honor their obligations. Changes in an issuer’s credit rating or the market’s perception of an issuer’s creditworthiness may also adversely affect the value of the Fund’s investment in that issuer. The degree of credit risk depends on an issuer’s or counterparty’s financial condition and on the terms of an obligation.

 

NEOS Enhanced Income Aggregate Bond ETF | Forward Contract Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Forward Contract Risk. Forward contracts involve the purchase or sale of a specific quantity of a government security at a specified price, with delivery and settlement at a specified future date. Forward contracts, unlike futures contracts, are not traded on exchanges and are not standardized; rather, banks and dealers act as principals in these markets, negotiating each transaction on an individual basis. The principals who deal in the forward markets are not required to continue to make markets in the currencies or commodities they trade and these markets can experience periods of illiquidity, sometimes of significant duration. There have been periods during which certain participants in these markets have refused to quote prices for certain currencies or commodities or have quoted prices with an unusually wide spread between the price at which they were prepared to buy and that at which they were prepared to sell.

 

NEOS Enhanced Income Aggregate Bond ETF | Futures Contract Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Futures Contract Risk. Futures are standardized, exchange-traded contracts that obligate a purchaser to take delivery, and a seller to make delivery, of a specific amount of an asset at a specified future date at a specified price. Unlike equities, which typically entitle the holder to a continuing ownership stake in an issuer, futures contracts normally specify a certain date for settlement in cash based on the level of the reference rate. The primary risks associated with the use of futures contracts, or swaps or other derivatives referencing futures contracts, are: (i) the imperfect correlation between the change in market value of the instruments held by the Fund and the price of the futures contract; (ii) possible lack of a liquid secondary market for a futures contract and the resulting inability to close a futures contract when desired; (iii) losses caused by unanticipated market movements, which are potentially unlimited; (iv) the Adviser’s inability to predict correctly the direction of prices and other economic factors; and (v) the possibility that the counterparty will default in the performance of its obligations.

 

NEOS Enhanced Income Aggregate Bond ETF | High Yield Securities Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

High Yield Securities Risk. Securities that are rated below investment-grade (commonly referred to as “junk bonds,” which may include those bonds rated below “BBB-” by S&P Global Ratings and Fitch Ratings, Inc. (“Fitch”) or below “Baa3” by Moody’s Investors Service, Inc. (“Moody’s”)), or are unrated, may be deemed speculative, may involve greater levels of risk than higher-rated securities of similar maturity and may be more likely to default.

 

NEOS Enhanced Income Aggregate Bond ETF | Income Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Income Risk. The Fund’s income may decline when yields fall. This decline can occur because the Fund may subsequently invest in lower-yielding bonds as bonds in its portfolio mature, are near maturity or are called, bonds in the Fund otherwise needs to purchase additional bonds.

 

NEOS Enhanced Income Aggregate Bond ETF | Interest Rate Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Interest Rate Risk. The risk that fixed income securities will decline in value because of an increase in interest rates; a fund with a longer average portfolio duration will be more sensitive to changes than a fund with a shorter average portfolio duration.

 

NEOS Enhanced Income Aggregate Bond ETF | Large Shareholder and Large-Scale Redemption Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Large Shareholder and Large-Scale Redemption Risk. Certain shareholders, including an Authorized Participant, a third-party investor, the Fund’s adviser or an affiliate of the Fund’s adviser, a market maker, or another entity, may from time to time own or manage a substantial amount of Fund shares, or may invest in the Fund and hold its investment for a limited period of time. There can be no assurance that any large shareholder or large group of shareholders would not redeem their investment. Redemptions of a large number of Fund shares could require the Fund to dispose of assets to meet the redemption requests, which can accelerate the realization of taxable income and/or capital gains and cause the Fund to make taxable distributions to its shareholders earlier than the Fund otherwise would have. In addition, under certain circumstances, non-redeeming shareholders may be treated as receiving a disproportionately large taxable distribution during or with respect to such year.

 

NEOS Enhanced Income Aggregate Bond ETF | Mortgage- and Asset-Backed Securities Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Mortgage- and Asset-Backed Securities Risk. Mortgage- and asset-backed securities represent interests in “pools” of mortgages or other assets, including consumer loans or receivables held in trust. Mortgage- and asset-backed securities are subject to credit, interest rate, prepayment and extension risks. These securities also are subject to risk of default on the underlying mortgage or asset, particularly during periods of economic downturn. Small movements in interest rates (both increases and decreases) may quickly and significantly reduce the value of certain mortgage-backed securities.

 

NEOS Enhanced Income Aggregate Bond ETF | Non-Agency Securities Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Non-Agency Securities Risk. There are no direct or indirect government or agency guarantees of payments in mortgage pools created by non-government issuers. Non-agency securities are also not subject to the same underwriting requirements for the underlying mortgages that are applicable to those mortgage-related securities that have a government or government-sponsored entity guarantee. In addition, a substantial portion of the nonagency securities in which the Fund invests may be rated below investment grade (commonly known as “junk bonds”). Non-agency mortgage-related securities are not traded on an exchange and there may be a limited market for the securities, especially when there is a perceived weakness in the mortgage and real estate market sectors. Without an active trading market, the non-agency mortgage-related securities held in the Fund’s portfolio may be particularly difficult to value because of the complexities involved in assessing the value of the underlying mortgage loans.

 

NEOS Enhanced Income Aggregate Bond ETF | Prepayment Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Prepayment Risk. During periods of falling interest rates, issuers of certain debt obligations may repay principal prior to the security’s maturity, which may cause the Fund or the Fund to have to reinvest in securities with lower yields or higher risk of default, resulting in a decline in the Fund’s income or return potential. Also, if a security subject to prepayment had been purchased at a premium, the value of the premium would be lost in the event of prepayment.

 

NEOS Enhanced Income Aggregate Bond ETF | Underlying ETF and Index Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Underlying ETF and Index Risk. The Fund will have exposure to underlying ETFs that track their respective indexes. Because the value of the Fund in part will be based on the value of one or more Underlying ETF, the Fund’s investment performance depends on the investment performance and associated risks of the Underlying ETFs. The Underlying ETFs are subject to many of the same structural risks as the Fund that are described in more detail herein, such as Authorized Participant Concentration Risk, Equity Securities Risk, Fluctuation of Net Asset Value Risk, Market Maker Risk, Market Risk, Operational Risk and Trading Issues Risk.

 

NEOS Enhanced Income Aggregate Bond ETF | U.S. Government Securities Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

U.S. Government Securities Risk. U.S. government securities may differ from other securities in their interest rates, maturities, times of issuance and other characteristics and may provide relatively lower returns than those of other securities. Similar to other issuers, changes to the financial condition or credit rating of the U.S. government may cause the value of the Fund’s U.S. government securities to decline.

Active Management Risk. The Fund is actively managed, which means that investment decisions are made based on investment views. There is no guarantee that the investment views will produce the desired results or expected returns, which may cause the Fund to fail to meet its investment objective or to underperform its benchmark index or funds with similar investment objectives and strategies. Furthermore, active trading that can accompany active management may result in high portfolio turnover, which may have a negative impact on performance. Active trading may result in higher brokerage costs or mark-up charges, which are ultimately passed on to shareholders of the Fund. Active trading may also result in adverse tax consequences.

 

NEOS Enhanced Income 1-3 Month T-Bill ETF | Derivatives Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Derivatives Risk. The Fund’s use of derivatives may reduce the Fund’s returns or increase volatility. Volatility is defined as the characteristic of a security, an index or a market to fluctuate significantly in price within a short time period. Derivatives may also be subject to counterparty risk, which is the risk that the other party in the transaction will not fulfill its contractual obligation. Counterparty risk for over-the-counter (“OTC”) derivatives is generally higher than that for derivatives traded on an exchange or through a clearing house. A risk of the Fund’s use of derivatives is that the fluctuations in their values may not correlate perfectly with the value of the underlying asset, the performance of the asset class to which the Fund seeks exposure or the performance of the overall markets. The possible lack of a liquid secondary market for derivatives and the resulting inability of the Fund to sell or otherwise close a derivatives position could expose the Fund to losses and could make derivatives more difficult for the Fund to value accurately. The Fund could also suffer losses related to its derivatives positions as a result of unanticipated market movements, or movements between the time of periodic reallocations of Fund assets, which losses are potentially unlimited. Certain derivatives may give rise to a form of leverage and may expose the Fund to greater risk and increase its costs. The impact of U.S. and global regulation of derivatives may make derivatives more costly, may limit the availability of derivatives, may delay or restrict the exercise by the Fund of termination rights or remedies upon a counterparty default under derivatives held by the Fund (which could result in losses), or may otherwise adversely affect the value or performance of derivatives.

 

NEOS Enhanced Income 1-3 Month T-Bill ETF | Exchange Traded Funds (“ETFs”) Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Exchange Traded Funds (“ETFs”) Risk. The Fund is structured as an ETF. As a result, the Fund is subject to special risks, including:

 

NEOS Enhanced Income 1-3 Month T-Bill ETF | Not Individually Redeemable [Member]  
Prospectus [Line Items]  
Risk [Text Block]
●Not Individually Redeemable. The Fund’s shares (“Shares”) are not redeemable by retail investors and may be redeemed only by Authorized Participants at net asset value (“NAV”) and only in Creation Units. A retail investor generally incurs brokerage costs when selling shares.

 

NEOS Enhanced Income 1-3 Month T-Bill ETF | Trading Issues [Member]  
Prospectus [Line Items]  
Risk [Text Block]
●Trading Issues. Trading in Shares on the Exchange may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in Shares inadvisable, such as extraordinary market volatility. There can be no assurance that Shares will continue to meet the listing requirements of the Exchange which may result in the Shares being delisted. An active trading market for the Shares may not be developed or maintained. If the Shares are traded outside a collateralized settlement system, the number of financial institutions that can act as Authorized Participants that can post collateral on an agency basis is limited, which may limit the market for the Shares.

 

 

NEOS Enhanced Income 1-3 Month T-Bill ETF | Market Price Variance Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]
●Market Price Variance Risk. The market prices of Shares will fluctuate in response to changes in NAV and supply and demand for Shares and will include a “bid-ask spread” charged by the exchange specialists, market makers or other participants that trade the Shares. There may be times when the market price and the NAV vary significantly. This means that Shares may trade at a discount to NAV.

 

○In times of market stress, market makers may step away from their role market making in the Shares and in executing trades, which can lead to differences between the market value of the Shares and the Fund’s NAV.

 

○The market price of the Shares may deviate from the Fund’s NAV, particularly during times of market stress, with the result that investors may pay significantly more or significantly less for the Shares than the Fund’s NAV, which is reflected in the bid and ask price for the Shares or in the closing price.

 

○In stressed market conditions, the market for the Shares may become less liquid in response to the deteriorating liquidity of the Fund’s portfolio. This adverse effect on the liquidity of the Shares may, in turn, lead to differences between the market value of the Shares and the Fund’s NAV.

 

NEOS Enhanced Income 1-3 Month T-Bill ETF | Authorized Participant Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]
●Authorized Participant Risk. Only an Authorized Participant may engage in creation or redemption transactions directly with the Fund. The Fund has a limited number of institutions that may act as an Authorized Participant on an agency basis (i.e., on behalf of other market participants). To the extent that Authorized Participants exit the business or are unable to proceed with creation or redemption orders with respect to the Fund and no other Authorized Participant is able to step forward to create or redeem Creation Units, Fund shares may be more likely to trade at a premium or discount to net asset value and possibly face trading halts or delisting. Authorized Participant concentration risk may be heightened for securities or instruments that have lower trading volumes.

 

Additionally, purchases and redemptions of creation units primarily with cash rather than through in-kind delivery of portfolio securities may cause the Fund to incur certain costs, including brokerage costs or taxable gains or losses that it might not have incurred if it made a redemption in-kind, and therefore decrease the Fund’s NAV to the extent not offset by a transaction fee payable by an AP.

 

NEOS Enhanced Income 1-3 Month T-Bill ETF | Market and Geopolitical Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Market and Geopolitical Risk. The increasing interconnectivity between global economies and financial markets increases the likelihood that events or conditions in one region or financial market may adversely impact issuers in a different country, region or financial market. Securities in the Fund’s portfolio may underperform due to inflation (or expectations for inflation), interest rates, global demand for particular products or resources, natural disasters, climate change and climate-related events, pandemics, epidemics, terrorism, regulatory events and governmental or quasi-governmental actions. The occurrence of global events similar to those in recent years may result in market volatility and may have long term effects on both the U.S. and global financial markets

 

 

NEOS Enhanced Income 1-3 Month T-Bill ETF | Options Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Options Risk. There are risks associated with the sale and purchase of put options. As a seller (writer) of a put option, the Fund will tend to lose money if the value of the reference index or security falls below the strike price. As the buyer of a put option, the Fund risks losing the entire premium invested in the option if the Fund does not exercise the option.

 

NEOS Enhanced Income 1-3 Month T-Bill ETF | Tax Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Tax Risk. The Fund invests in derivatives. The federal income tax treatment of a derivative may not be as favorable as a direct investment in an underlying asset. Derivatives may produce taxable income and taxable realized gain. Derivatives may adversely affect the timing, character and amount of income the Fund realizes from its investments. As a result, a larger portion of the Fund’s distributions may be treated as ordinary income rather than as capital gains. In addition, certain derivatives are subject to mark-to-market or straddle provisions of the Internal Revenue Code of 1986, as amended (the “Internal Revenue Code”). If such provisions are applicable, there could be an increase (or decrease) in the amount of taxable dividends paid by the Fund.

 

NEOS Enhanced Income 1-3 Month T-Bill ETF | Valuation Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Valuation Risk. The price the Fund could receive upon the sale of a security or other asset may differ from the Fund’s valuation of the security or other asset, particularly for securities or other assets that trade in low volume or volatile markets or that are valued using a fair value methodology as a result of trade suspensions or for other reasons. In addition, the value of the securities or other assets in the Fund’s portfolio may change on days or during time periods when shareholders will not be able to purchase or sell the Fund’s shares. Authorized Participants who purchase or redeem Fund shares on days when the Fund is holding fair-valued securities may receive fewer or more shares, or lower or higher redemption proceeds, than they would have received had the Fund not fair-valued securities or used a different valuation methodology. The Fund’s ability to value investments may be impacted by technological issues or errors by pricing services or other third- party service providers.

 

NEOS Enhanced Income 1-3 Month T-Bill ETF | Forward Contract Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Forward Contract Risk. Forward contracts involve the purchase or sale of a specific quantity of a government security at a specified price, with delivery and settlement at a specified future date. Forward contracts, unlike futures contracts, are not traded on exchanges and are not standardized; rather, banks and dealers act as principals in these markets, negotiating each transaction on an individual basis. The principals who deal in the forward markets are not required to continue to make markets in the currencies or commodities they trade and these markets can experience periods of illiquidity, sometimes of significant duration. There have been periods during which certain participants in these markets have refused to quote prices for certain currencies or commodities or have quoted prices with an unusually wide spread between the price at which they were prepared to buy and that at which they were prepared to sell.

 

NEOS Enhanced Income 1-3 Month T-Bill ETF | Futures Contract Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Futures Contract Risk. Futures are standardized, exchange-traded contracts that obligate a purchaser to take delivery, and a seller to make delivery, of a specific amount of an asset at a specified future date at a specified price. Unlike equities, which typically entitle the holder to a continuing ownership stake in an issuer, futures contracts normally specify a certain date for settlement in cash based on the level of the reference rate. The primary risks associated with the use of futures contracts, or swaps or other derivatives referencing futures contracts, are: (i) the imperfect correlation between the change in market value of the instruments held by the Fund and the price of the futures contract; (ii) possible lack of a liquid secondary market for a futures contract and the resulting inability to close a futures contract when desired; (iii) losses caused by unanticipated market movements, which are potentially unlimited; (iv) the Adviser’s inability to predict correctly the direction of prices and other economic factors; and (v) the possibility that the counterparty will default in the performance of its obligations.

 

NEOS Enhanced Income 1-3 Month T-Bill ETF | Income Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Income Risk. The Fund’s income may decline when yields fall. This decline can occur because the Fund may subsequently invest in lower-yielding bonds as bonds in its portfolio mature, are near maturity or are called, bonds in the Fund otherwise needs to purchase additional bonds.

 

NEOS Enhanced Income 1-3 Month T-Bill ETF | Interest Rate Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Interest Rate Risk. An increase in interest rates may cause the value of fixed-income securities held by the Fund or the Underlying Investments to decline. The Fund may be subject to a greater risk of rising interest rates due to the current period of historically low rates and the effect of potential government fiscal policy initiatives and resulting market reaction to those initiatives.

 

NEOS Enhanced Income 1-3 Month T-Bill ETF | Underlying ETF and Index Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Underlying ETF and Index Risk. The Fund will have exposure to underlying ETFs that track their respective indexes. Because the value of the Fund in part will be based on the value of the Underlying ETF, the Fund’s investment performance depends on the investment performance and associated risks of the Underlying ETFs. The Underlying ETFs are subject to many of the same structural risks as the Fund that are described in more detail herein, such as Authorized Participant Concentration Risk, Equity Securities Risk, Fluctuation of Net Asset Value Risk, Market Maker Risk, Market Risk, Operational Risk and Trading Issues Risk.

 

NEOS Enhanced Income 1-3 Month T-Bill ETF | U.S. Government Securities Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

U.S. Government Securities Risk. U.S. government securities may differ from other securities in their interest rates, maturities, times of issuance and other characteristics and may provide relatively lower returns than those of other securities. Similar to other issuers, changes to the financial condition or credit rating of the U.S. government may cause the value of the Fund’s U.S. government securities to decline.

Active Management Risk. The Fund is actively managed, which means that investment decisions are made based on investment views. There is no guarantee that the investment views will produce the desired results or expected returns, which may cause the Fund to fail to meet its investment objective or to underperform its benchmark index or funds with similar investment objectives and strategies. Furthermore, active trading that can accompany active management may result in high portfolio turnover, which may have a negative impact on performance. Active trading may result in higher brokerage costs or mark-up charges, which are ultimately passed on to shareholders of the Fund. Active trading may also result in adverse tax consequences.

 

NEOS Nasdaq-100(R) High Income ETF | Concentration Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Concentration Risk. The Fund may invest in up to 100% of the constituents of the Nasdaq-100®, which itself may have concentration in certain regions, economies, countries, markets, industries or sectors. The Fund may be susceptible to an increased risk of loss, including losses due to adverse events that affect the Fund’s investments more than the market as a whole, to the extent that the Fund’s investments are concentrated in the securities of a particular issuer or issuers, country, group of countries, region, market, industry, group of industries, sector or asset class.

 

NEOS Nasdaq-100(R) High Income ETF | Covered Call Option Writing Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Covered Call Option Writing Risk. By writing covered call options, in return for the receipt of premiums, the Fund will give up the opportunity to benefit from potential increases in the value of the Nasdaq-100® above the exercise prices of such options, but will continue to bear the risk of declines in the value of the Nasdaq-100®. The premiums received from the options may not be sufficient to offset any losses sustained from the volatility of the underlying stocks over time. In addition, the Fund’s ability to sell the securities underlying the options will be limited while the options are in effect unless the Fund cancels out the option positions through the purchase of offsetting identical options prior to the expiration of the written options. Exchanges may suspend the trading of options in volatile markets. If trading is suspended, the Fund may be unable to write options at times that may be desirable or advantageous to do so, which may increase the risk of tracking error.

 

NEOS Nasdaq-100(R) High Income ETF | Derivatives Risk [Member]

Derivatives Risk. The Fund’s use of derivatives may reduce the Fund’s returns or increase volatility. Volatility is defined as the characteristic of a security, an index or a market to fluctuate significantly in price within a short time period. Derivatives may also be subject to counterparty risk, which is the risk that the other party in the transaction will not fulfill its contractual obligation. Counterparty risk for over-the-counter (“OTC”) derivatives is generally higher than that for derivatives traded on an exchange or through a clearing house. A risk of the Fund’s use of derivatives is that the fluctuations in their values may not correlate perfectly with the value of the underlying asset, the performance of the asset class to which the Fund seeks exposure or the performance of the overall markets. The possible lack of a liquid secondary market for derivatives and the resulting inability of the Fund to sell or otherwise close a derivatives position could expose the Fund to losses and could make derivatives more difficult for the Fund to value accurately. The Fund could also suffer losses related to its derivatives positions as a result of unanticipated market movements, or movements between the time of periodic reallocations of Fund assets, which losses are potentially unlimited.

Equity Risk. The net asset value of the Fund will fluctuate based on changes in the value of the U.S. equity securities held by the Fund. Equity prices can fall rapidly in response to developments affecting a specific company or industry, or to changing economic, political or market conditions.

 

NEOS Nasdaq-100(R) High Income ETF | Issuer Risk [Member]

Risk [Text Block]

Issuer Risk. Changes in the financial condition or credit rating of an issuer or counterparty, changes in specific economic or political conditions that affect a particular type of security or issuer, and changes in general economic or political conditions can affect a security’s or instrument’s value. The values of securities of smaller, less well-known issuers can be more volatile than those of larger issuers. Issuer-specific events can have a negative impact on the value of the Fund.

 

NEOS Nasdaq-100(R) High Income ETF | Market and Geopolitical Risk [Member]

Risk [Text Block]

Market and Geopolitical Risk. The prices of securities held by the Fund may decline in response to certain events taking place around the world, including those directly involving the companies whose securities are owned by the Fund; conditions affecting the general economy; overall market changes; local, regional or global political, social or economic instability; and currency, interest rate and commodity price fluctuations. The equity securities purchased by the Fund may involve large price swings and potential for loss. Investors in the Fund should have a long-term perspective and be able to tolerate potentially sharp declines in value. The value of your investment in the Fund is based on the market prices of the securities the Fund holds. These prices change daily due to economic and other events that affect markets generally, as well as those that affect particular regions, countries, industries, companies or governments.

Options Risk. There are risks associated with the sale and purchase of call and put options. As a seller (writer) of a put option, the Fund will tend to lose money if the value of the reference index or security falls below the strike price. As the seller (writer) of a call option, the Fund will tend to lose money if the value of the reference index or security rises above the strike price. As the buyer of a put or call option, the Fund risks losing the entire premium invested in the option if the Fund does not exercise the option.

 

NEOS Nasdaq-100(R) High Income ETF | Sector Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Sector Risk. Sector risk is the possibility that securities within the same group of industries will decline in price due to sector-specific market or economic developments. If the Fund invests more heavily in a particular sector, the value of its shares may be especially sensitive to factors and economic risks that specifically affect that sector. As a result, the Fund’s share price may fluctuate more widely than the value of shares of a fund that invests in a broader range of industries.

 

NEOS Nasdaq-100(R) High Income ETF | Information Technology Sector Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Information Technology Sector Risk. Because the Nasdaq-100® Index has been concentrated in the information technology sector, the Fund may be sensitive to changes in, and its performance may depend to a greater extent on, the overall condition of the information technology sector. Information technology companies face intense competition, both domestically and internationally, which may have an adverse effect on profit margins. Information technology companies may have limited product lines, markets, financial resources or personnel. The products of information technology companies may face product obsolescence due to rapid technological developments and frequent new product introduction, unpredictable changes in growth rates and competition for the services of qualified personnel. Companies in the information technology sector are heavily dependent on patent protection and the expiration of patents may adversely affect the profitability of these companies.

In addition, the value of the securities or other assets in the Fund’s portfolio may change on days or during time periods when shareholders will not be able to purchase or sell the Fund’s shares. Authorized Participants who purchase or redeem Fund shares on days when the Fund is holding fair-valued securities may receive fewer or more shares, or lower or higher redemption proceeds, than they would have received had the Fund not fair-valued securities or used a different valuation methodology. The Fund’s ability to value investments may be impacted by technological issues or errors by pricing services or other third- party service providers.

 

 

NEOS Nasdaq-100(R) High Income ETF | Large Shareholder and Large-Scale Redemption Risk [Member]

Risk [Text Block]

Large Shareholder and Large-Scale Redemption Risk. Certain shareholders, including an Authorized Participant, a third-party investor, the Fund’s adviser or an affiliate of the Fund’s adviser, a market maker, or another entity, may from time to time own or manage a substantial amount of Fund shares, or may invest in the Fund and hold its investment for a limited period of time. There can be no assurance that any large shareholder or large group of shareholders would not redeem their investment. Redemptions of a large number of Fund shares could require the Fund to dispose of assets to meet the redemption requests, which can accelerate the realization of taxable income and/or capital gains and cause the Fund to make taxable distributions to its shareholders earlier than the Fund otherwise would have. In addition, under certain circumstances, non-redeeming shareholders may be treated as receiving a disproportionately large taxable distribution during or with respect to such year.

 

NEOS Nasdaq-100(R) High Income ETF | Authorized Participants, Market Makers, and Liquidity Providers Concentration Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Authorized Participants, Market Makers, and Liquidity Providers Concentration Risk. The Fund has a limited number of financial institutions that may act as Authorized Participants (“APs”). In addition, there may be a limited number of market makers and/or liquidity providers in the marketplace. To the extent either of the following events occur, Shares may trade at a material discount to NAV and possibly face delisting: (i) APs exit the business or otherwise become unable to process creation and/or redemption orders and no other APs step forward to perform these services, or (ii) market makers and/or liquidity providers exit the business or significantly reduce their business activities and no other entities step forward to perform their functions.

Risk [Text Block]

Cybersecurity Risk. The computer systems, networks and devices used by the Funds and their service providers to carry out routine business operations employ a variety of protections designed to limit damage or interruption from computer viruses, network failures, computer and telecommunication failures, infiltration by unauthorized persons and security breaches. Despite the various protections utilized by the Funds and their service providers, systems, networks, or devices potentially can be breached. Each Fund and its shareholders could be negatively impacted as a result of a cybersecurity breach.

 

Cybersecurity breaches can include unauthorized access to systems, networks, or devices; infection from computer viruses or other malicious software code; and attacks that shut down, disable, slow, or otherwise disrupt operations, business processes, or website access or functionality. Cybersecurity breaches may cause disruptions and impact each Fund’s business operations, potentially resulting in financial losses; interference with each Fund’s ability to calculate its NAV; impediments to trading; the inability of each Fund, the adviser, and other service providers to transact business; violations of applicable privacy and other laws; regulatory fines, penalties, reputational damage, reimbursement or other compensation costs, or additional compliance costs; as well as the inadvertent release of confidential information.

 

Similar adverse consequences could result from cybersecurity breaches affecting issuers of securities in which the Funds invest; counterparties with which the Funds engage in transactions; governmental and other regulatory authorities; exchange and other financial market operators, banks, brokers, dealers, insurance companies, and other financial institutions (including financial intermediaries and service providers for a Fund’s shareholders); and other parties. In addition, substantial costs may be incurred by these entities in order to limit any cybersecurity breaches in the future.

Market Trading Risk. The Fund faces numerous market trading risks, including the potential lack of an active market for the Shares, losses from trading in secondary markets, and disruption in the creation/redemption process of the Fund.

Risk [Text Block]

Shares May Trade at Prices Other Than NAV Risk. As with all ETFs, Shares may be bought and sold in the secondary market at market prices. Although it is expected that the market price of Shares will approximate the Fund’s NAV, there may be times when the market price of Shares is more than the NAV intra-day (premium) or less than the NAV intra-day (discount) due to supply and demand of Shares or during periods of market volatility. This risk is heightened in times of market volatility, periods of steep market declines, and periods when there is limited trading activity for Shares in the secondary market, in which case such premiums or discounts may be significant.

Non-Diversification Risk. To the extent the Fund is non-diversified, it may invest a larger portion of its assets in a limited number of companies than a diversified fund.  In such circumstances, a change in the value of one or a few issuers’ securities will therefore affect the value of the Fund more than if it was a diversified fund. Because a relatively high percentage of the Fund’s assets may be invested in the securities of a limited number of companies that could be in the same or related economic sectors, the Fund’s portfolio may be more susceptible to any single economic, technological or regulatory occurrence than the portfolio of a diversified fund.

Risk [Text Block]

Derivatives Risk. Options are a derivative investment. The use of derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities and other traditional investments. These risks include (i) the risk that the counterparty to a derivative transaction may not fulfil its contractual obligations; (ii) risk of mispricing or improper valuation; and (iii) the risk that changes in the value of the derivative may not correlate perfectly with the underlying asset, rate or index. Derivative prices are highly volatile and may fluctuate substantially during a short period of time. Such prices are influenced by numerous factors that affect the markets, including, but not limited to: changing supply and demand relationships; government programs and policies; national and international political and economic events, changes in interest rates, inflation and deflation and changes in supply and demand relationships.

There can be no assurance that Shares will continue to meet the listing requirements of the Exchange which may result in the Shares being delisted. An active trading market for the Shares may not be developed or maintained. If the Shares are traded outside a collateralized settlement system, the number of financial institutions that can act as Authorized Participants that can post collateral on an agency basis is limited, which may limit the market for the Shares.

●Market Price Variance Risk. The market prices of Shares will fluctuate in response to changes in NAV and supply and demand for Shares and will include a “bid-ask spread” charged by the exchange specialists, market makers or other participants that trade the Shares. There may be times when the market price and the NAV vary significantly. This means that Shares may trade at a discount to NAV.

 

○In times of market stress, market makers may step away from their role market making in the Shares and in executing trades, which can lead to differences between the market value of the Shares and the Fund’s NAV.

 

○The market price of the Shares may deviate from the Fund’s NAV, particularly during times of market stress, with the result that investors may pay significantly more or significantly less for the Shares than the Fund’s NAV, which is reflected in the bid and ask price for the Shares or in the closing price.

 

○In stressed market conditions, the market for the Shares may become less liquid in response to the deteriorating liquidity of the Fund’s portfolio. This adverse effect on the liquidity of the Shares may, in turn, lead to differences between the market value of the Shares and the Fund’s NAV.

●Authorized Participant Risk. Only an Authorized Participant may engage in creation or redemption transactions directly with the Fund. The Fund has a limited number of institutions that may act as an Authorized Participant on an agency basis (i.e., on behalf of other market participants). To the extent that Authorized Participants exit the business or are unable to proceed with creation or redemption orders with respect to the Fund and no other Authorized Participant is able to step forward to create or redeem Creation Units, Fund shares may be more likely to trade at a premium or discount to net asset value and possibly face trading halts or delisting. Authorized Participant concentration risk may be heightened for securities or instruments that have lower trading volumes.

 

Additionally, purchases and redemptions of creation units primarily with cash rather than through in-kind delivery of portfolio securities may cause the Fund to incur certain costs, including brokerage costs or taxable gains or losses that it might not have incurred if it made a redemption in-kind, and therefore decrease the Fund’s NAV to the extent not offset by a transaction fee payable by an AP.

Market and Geopolitical Risk. The increasing interconnectivity between global economies and financial markets increases the likelihood that events or conditions in one region or financial market may adversely impact issuers in a different country, region or financial market. Securities in the Fund’s portfolio may underperform due to inflation (or expectations for inflation), interest rates, global demand for particular products or resources, natural disasters, climate change and climate-related events, pandemics, epidemics, terrorism, international conflicts, regulatory events and governmental or quasi-governmental actions. The occurrence of global events similar to those in recent years may result in market volatility and may have long term effects on financial markets worldwide.

 

NEOS Bitcoin High Income ETF | Options Risk [Member]

Risk [Text Block]

Options Risk. Buying and selling (writing) options are speculative activities and entail greater than ordinary investment risks. Options enable the Fund to purchase exposure that is significantly greater than the premium paid. Consequently, the value of such options can be volatile, and a small investment in options can have a large impact on the performance of the Fund. The Fund risks losing all or part of the cash paid (premiums) for purchasing options. Even a small decline in the value of a reference asset underlying call options or a small increase in the value of a reference asset underlying put options can result in the entire investment in such options being lost. The Fund’s options also may fail to track the performance of their underlying reference asset, which may limit the effectiveness of the Fund’s strategy. The potential loss from written options can exceed the Fund’s initial investment in such options and could be unlimited.

 

NEOS Bitcoin High Income ETF | Tax Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Tax Risk. The Fund invests in derivatives. The federal income tax treatment of a derivative may not be as favorable as a direct investment in an underlying asset. Derivatives may produce taxable income and taxable realized gain. Derivatives may adversely affect the timing, character and amount of income the Fund realizes from its investments. As a result, a larger portion of the Fund’s distributions may be treated as ordinary income rather than as capital gains. In addition, certain derivatives are subject to mark-to-market or straddle provisions of the Internal Revenue Code. If such provisions are applicable, there could be an increase (or decrease) in the amount of taxable dividends paid by the Fund. The use of derivatives, such as call options, may cause the Fund to realize higher amounts of short-term capital gains or otherwise affect the Fund’s ability to pay out dividends subject to preferential rates or the dividend deduction, thereby increasing the amount of taxes payable by some shareholders. The writing of call options by the Fund may significantly reduce or eliminate the ability to make distributions eligible to be treated as qualified dividend income or as eligible for the dividends received deduction for corporate shareholders.

 

If the Fund’s distributions exceed its earnings and profits, all or a portion of the distributions made for a taxable year may be recharacterized as a return of capital to shareholders. A return of capital distribution will generally not be taxable, but will reduce each shareholder’s cost basis in the Fund and result in a higher capital gain or lower capital loss when shares on which the distribution was received are sold. After a shareholder’s basis in shares has been reduced to zero, distributions in excess of earnings and profits will be treated as gain from the sale of the shareholder’s shares.

 

To qualify as a regulated investment company (“RIC”), the Fund must meet certain requirements concerning the source of its income. The Fund’s investment in the Subsidiary is intended to provide exposure to bitcoin in a manner that is consistent with the “qualifying income” requirement applicable to RICs. The Internal Revenue Service (“IRS”) has ceased issuing private letter rulings regarding whether the use of subsidiaries by investment companies to invest in certain instruments constitutes qualifying income. If the IRS determines that this source of income is not “qualifying income,” the Fund may cease to qualify as a RIC because the Fund has not received a private letter ruling and is not able to rely on private letter rulings issued to other taxpayers. Failure to qualify as a RIC could subject the Fund to adverse tax consequences, including a federal income tax on its net income at regular corporate rates, as well as a tax to shareholders on such income when distributed as an ordinary dividend.

 

Based on the principles underlying private letter rulings previously issued to other taxpayers, the Fund intends to treat its income from the Subsidiary as qualifying income without any such ruling from the IRS. The tax treatment of the Fund’s investment in the Subsidiary may be adversely affected by future legislation, court decisions, Treasury Regulations and/or guidance issued by the IRS that could affect whether income derived from such investments is “qualifying income” under Subchapter M of the Internal Revenue Code, or otherwise affect the character, timing and/or amount of the Fund’s taxable income or any gains or distributions made by the Fund.

Valuation Risk. The price the Fund could receive upon the sale of a security or other asset may differ from the Fund’s valuation of the security or other asset, particularly for securities or other assets that trade in low volume or volatile markets or that are valued using a fair value methodology. In addition, the value of the securities or other assets in the Fund’s portfolio may change on days or during time periods when shareholders will not be able to purchase or sell the Fund’s shares. Authorized Participants who purchase or redeem Fund shares on days when the Fund is holding fair-valued securities may receive fewer or more shares, or lower or higher redemption proceeds, than they would have received had the Fund not fair-valued securities or used a different valuation methodology. The Fund’s ability to value investments may be impacted by technological issues or errors by pricing services or other third- party service providers.

Large Shareholder and Large-Scale Redemption Risk. Certain shareholders, including an Authorized Participant, a third-party investor, the Fund’s adviser or an affiliate of the Fund’s adviser, a market maker, or another entity, may from time to time own or manage a substantial amount of Fund shares, or may invest in the Fund and hold its investment for a limited period of time. There can be no assurance that any large shareholder or large group of shareholders would not redeem their investment. Redemptions of a large number of Fund shares could require the Fund to dispose of assets to meet the redemption requests, which can accelerate the realization of taxable income and/or capital gains and cause the Fund to make taxable distributions to its shareholders earlier than the Fund otherwise would have. In addition, under certain circumstances, non-redeeming shareholders may be treated as receiving a disproportionately large taxable distribution during or with respect to such year.

Risk [Text Block]

Spot Bitcoin ETP Risk. The value of a Spot Bitcoin ETP security may be more volatile than the market as a whole and may perform differently from the value of the market as a whole. It is possible that Spot Bitcoin ETP issuer-specific attributes may cause an investment held by the Fund in such Spot Bitcoin ETP to be more volatile than the market generally.

 

Many of the risks associated with Spot Bitcoin ETP securities are the same as the risks of owning Bitcoin directly. See Bitcoin Risk.

 

Spot Bitcoin ETPs have been in existence a relatively short period of time with a short trading history. Trading in Spot Bitcoin ETP shares is a recent development. If a Spot Bitcoin ETP’s creation and redemption process is interrupted or experiences difficulties, the arbitrage mechanism utilized by authorized participants to reduce the differences between the Spot Bitcoin ETP’s market price and net asset value may not work as intended and the market price of the Bitcoin ETP shares may fall or otherwise diverge from the Spot Bitcoin ETP’s net asset value, which may result in the Spot Bitcoin ETP’s shares trading at an increased premium or discount. A Spot Bitcoin ETP may suspend the issuance of shares at any time which will impact the price of shares of a Spot Bitcoin ETP, resulting in significant difference (premium/discount) between the Spot Bitcoin ETP’s market price and its net asset value. Additionally, the Fund may be unable to transact in the shares of the Spot Bitcoin ETP at an acceptable price and therefore the Fund may be unable to achieve its investment objective.

 

Cybersecurity or other threats to a Spot Bitcoin ETP’s account at its custodian could result in the halting of the Spot Bitcoin ETP’s operations and a loss of the Spot Bitcoin ETP’s assets, which could result in a reduction of the value of the shares of the Spot Bitcoin ETP and the Fund.

 

Spot Bitcoin ETPs are subject to custodian risk including if the custodian fails to provide services as required or terminates the custodian agreement.

 

Spot Bitcoin ETPs determine the spot price of Bitcoin and calculate their net asset values in reliance on composite indexes and other pricing sources. These indexes have a limited operating history. Thus, there is a risk that the price reported by the indexes could fail to track the global Bitcoin price, which would adversely affect the value of a Spot Bitcoin ETP’s shares. The value of a Spot Bitcoin as represented by an index or other pricing source used by a Spot Bitcoin ETP could be adversely affected by trading activity on digital asset platforms.

 

Spot Bitcoin ETPs are not registered as an investment company subject to the 1940 Act. Accordingly, investors in Spot Bitcoin ETPs do not have the protections expressly provided by that statute, including: provisions preventing Spot Bitcoin ETP insiders from managing a Spot Bitcoin ETP to their benefit and to the detriment of shareholders; provisions preventing a Spot Bitcoin ETP from issuing securities having inequitable or discriminatory provisions; provisions preventing management by irresponsible persons; provisions preventing the use of unsound or misleading methods of computing Spot Bitcoin ETP earnings and asset value; provisions prohibiting suspension of redemptions (except under limited circumstances); provisions limiting fund leverage; provisions imposing a fiduciary duty on fund managers with respect to receipt of compensation for services; and provisions preventing changes in a Spot Bitcoin ETP’s character without the consent of shareholders. Because the Fund invests in one or more Spot Bitcoin ETPs indirectly through the Subsidiary, the Fund’s investments are expected to be subject to loss as a result of these risks.

Bitcoin Options Risk. There are risks associated with the sale and purchase of options on a Bitcoin-related instrument. Due to the limited operating history of the trading of options on Bitcoin-related instruments, adverse performance of the options or adverse legislative or regulatory developments regarding Bitcoin options could significantly harm the value of the Fund. If the Fund’s ability to obtain exposure to these options contracts consistent with its investment objective is disrupted for any reason including, for example, limited liquidity in the bitcoin options market, limitations imposed by a listing exchange, interruption to the normal operations on an exchange or the facilities of an exchange, the Fund may not be able to achieve its investment objective and may experience significant losses. Any disruption in the Fund’s ability to obtain exposure to options on Bitcoin-related instrument may cause the Fund’s performance to deviate from the performance of bitcoin. Bitcoin option transaction risks are subject to the risks of investment in Bitcoin (see “Bitcoin Risk”) and options risk (see “Options Risk”).

Bitcoin Risk. The value of the Fund’s investment in Spot Bitcoin ETPs and options on Bitcoin-related instruments is subject to fluctuations in the value of Bitcoin. Bitcoin is a relatively new innovation and the market for bitcoin is subject to rapid price swings, changes and uncertainty. The further development of the Bitcoin network and the acceptance and use of bitcoin are subject to a variety of factors that are difficult to evaluate. The value of bitcoin has been, and may continue to be, substantially dependent on speculation, such that trading and investing in these assets generally may not be based on fundamental analysis. The slowing, stopping or reversing of the development of the Bitcoin network or the acceptance of bitcoin may adversely affect the price of bitcoin. Bitcoin is subject to the risk of fraud, theft, manipulation or security failures, operational or other problems that impact the digital asset trading venues on which bitcoin trades. The Bitcoin blockchain may contain flaws that can be exploited by hackers. A significant portion of bitcoin is held by a small number of holders sometimes referred to as “whales.” Transactions of these holders may have the ability to manipulate the price of bitcoin.

 

Unlike the exchanges for more traditional assets, such as equity securities and futures contracts, bitcoin and the digital asset trading venues on which it trades are largely unregulated and highly fragmented and digital asset trading venues may be operating out of compliance with regulations. As a result of the lack of regulation, individuals or groups may engage in fraud or market manipulation (including using social media to promote bitcoin in a way that artificially increases the price of bitcoin). Investors may be more exposed to the risk of theft, fraud and market manipulation than when investing in more traditional asset classes. Over the past several years, a number of digital asset trading venues have been closed due to fraud, failure or security breaches. Investors in bitcoin may have little or no recourse should such theft, fraud or manipulation occur and could suffer significant losses. Legal or regulatory changes may negatively impact the operation of the Bitcoin network or restrict the use of bitcoin. The digital asset trading venues upon which bitcoin trades have been subject to enforcement actions by regulatory authorities, and the Bitcoin Futures ETFs and Spot Bitcoin ETPs may be negatively impacted by such regulatory enforcement actions. Any such actions could significantly reduce the number of venues upon which bitcoin trades and could negatively impact the bitcoin futures contracts held by the Bitcoin Futures ETFs that reference the price of bitcoin or the bitcoin held by the Spot Bitcoin ETPs. In addition, digital asset trading venues, bitcoin miners, and other participants may have significant exposure to other digital assets. Instability in the price, availability or legal or regulatory status of those instruments may adversely impact the operation of the digital asset trading venues and the Bitcoin network. The realization of any of these risks could result in a decline in the acceptance of bitcoin and consequently a reduction in the value of bitcoin, bitcoin futures contracts, and shares of the Spot Bitcoin ETPs and options on Bitcoin-related instruments held by the Fund. Such occurrences could also impair the Bitcoin-related instruments’ ability to meet their investment objective pursuant to their respective investment strategy.

 

The Bitcoin network is maintained and secured by a group of validators who “mine” bitcoin, which involves contributing computer power to the network to validate transactions, maintain security and finalize settlement. The Bitcoin blockchain relies on a consensus mechanism whereby miners agree on the accurate state of the database. If a malicious actor (or group of actors) were to gain control of more than 50% the mining (or “hash”) power in the network, even temporarily, they would have the ability to block new transactions from being confirmed and could, over time, reverse or reorder prior transactions. Although it may be challenging for a malicious actor (or group of actors) to gain control of 50% of the mining (or “hash”) power in the Bitcoin blockchain, such an attack would significantly impact the value of bitcoin, and thereby of the bitcoin futures contracts held by the Bitcoin Futures ETF and the bitcoin held by the Spot Bitcoin ETPs.

 

A blockchain is a public database that is updated, shared and maintained across many computers in a network. The software that powers a blockchain is known as its protocol. Like all software, these protocols may update or change from time-to-time. In the case of the Bitcoin protocol, updates are made based on proposals submitted by developers, but only if a majority of the users and miners adopt the new proposals and update their individual copies of the protocol. Certain upgrade proposals to a blockchain may not be accepted by all the participants in an ecosystem. If one significant group adopts a proposed upgrade and another does not – or if groups adopt different upgrades – this can result in a “fork” of the blockchain, wherein two distinct sets of users and validators or users and miners run two different versions of a protocol. If the versions are sufficiently different such that the two versions of the protocol cannot simultaneously maintain and update a shared record of the blockchain database, it is called a “hard fork.” A hard fork can result in the creation of two competing blockchains, each with its own native crypto assets. For instance, on August 1, 2017, two factions in the Bitcoin community could not agree on whether or not to adopt an upgrade to the Bitcoin protocol related to how to scale throughput on the blockchain. The disagreement created a fork, with the smaller group taking the name “Bitcoin Cash” and running its own blockchain and related native crypto asset. The larger group retained the name Bitcoin for its blockchain and held bitcoin as the native crypto asset. Additional forks of the Bitcoin blockchain are possible. A large-scale fork could introduce risk, uncertainty, or confusion into the Bitcoin blockchain, or could fraction the value of the main blockchain and its native crypto asset, which could significantly impact the value of bitcoin and options on Bitcoin-related instruments held by the Fund. Additionally, a hack of the Bitcoin blockchain or one or more projects that interact with or that are built on top of the Bitcoin blockchain could negatively impact the price of bitcoin, whether it leads to another hard fork or not, and thereby the value of the bitcoin held by the Spot Bitcoin ETPs and options on Bitcoin-related instruments held by the Fund.

 

The Bitcoin blockchain and its native crypto asset, bitcoin, face numerous challenges to gaining widespread adoption as an alternative payments system, including the slowness of transaction processing and finality, variability in transaction fees and volatility in bitcoin’s price. It is not clear that the Bitcoin blockchain or bitcoin can overcome these and other impediments, which could harm the long-term adoption of the Bitcoin blockchain and bitcoin as an alternative payment system, and thereby negatively impact the price of bitcoin. In addition, alternative public blockchains have been developed and may in the future develop that compete with the Bitcoin blockchain and may have significant advantages as alternative payment systems, including higher throughput, lower fees, faster settlement and finalization, and the ability to facilitate untraceable and/or privacy-shielded transactions through the use of zero-knowledge cryptography or other means. It is possible that these alternative public blockchains and their native crypto assets may be more successful than the Bitcoin blockchain and bitcoin in gaining adoption as an alternative payments system, which could limit the long-term adoption of the Bitcoin blockchain and bitcoin, thereby negatively impact the price of bitcoin. Such alternative public blockchains, such as the Ethereum network, allow users to write and implement smart contracts—that is, general-purpose code that executes on every computer in the network and can instruct the transmission of information and value based on a sophisticated set of logical conditions. Using smart contracts, users can create markets, store registries of debts or promises, represent the ownership of property, move funds in accordance with conditional instructions and create other digital assets. Furthermore, traditional payment systems may improve their own technical capabilities and offer faster settlement times, faster finalization and lower fees. This could make it more difficult for the Bitcoin blockchain and bitcoin to gain traction as an alternative payments system, which could limit the long-term adoption of the Bitcoin blockchain and bitcoin, and thereby negatively impact the price of bitcoin. Finally, one means by which the ecosystem surrounding the Bitcoin blockchain has attempted to mitigate concerns about the slowness of transaction processing and finality and the variability of transaction fees has been through the development of so-called Layer 2 networks, including the “Lightning Network.” Layer 2 networks are separate blockchains built on top of “Layer 1” blockchains like the Bitcoin blockchain for the purpose of augmenting the throughput of the Layer 1 blockchain, and often, providing lower fees for transaction processing and faster settlement. Layer 2 blockchains introduce certain risks into the Bitcoin ecosystem that should be considered. For instance, Layer 2 blockchains are a relatively new and still developing technology. Technological issues – including hacks, bugs, or failures – could introduce risk or harm confidence in the Bitcoin ecosystem, which could negatively impact the price of bitcoin. In addition, users may choose to settle an increasing share of transactions on Layer 2 blockchains, which could negatively impact the transaction activity on, and the amount of fee revenue generated by, the Bitcoin blockchain itself, which could negatively impact the price of bitcoin. If these or other developments negatively impact the price of bitcoin, this would negatively impact the value of the Bitcoin-related instruments held by the Fund.

 

The realization of any of these risks could result in a decline in the acceptance of Bitcoin and consequently a reduction in the value of Bitcoin, Spot Bitcoin ETPs, options on Bitcoin-related instruments, and the Fund.

Bitcoin Tax Risk. By investing in Spot Bitcoin ETPs indirectly through the Subsidiary, the Fund will obtain exposure to the crypto asset Bitcoin within the federal tax requirements that apply to the Fund. However, because the Subsidiary is a controlled foreign corporation organized under the laws of the Cayman Islands, any income received by the Fund from its investments in the Subsidiary will be passed through to the Fund as ordinary income, which may be taxed at less favorable rates than capital gains.

 

A direct investment by the Fund in a Spot Bitcoin ETP will generally be treated as a direct investment in Bitcoin for U.S. federal income tax purposes. In order to qualify for the special tax treatment accorded a regulated investment company (“RIC”) and its shareholders, Subchapter M of the Internal Revenue Code of 1986, as amended (the “Code”) requires, among other things, that at least 90% of the Fund’s income be “qualifying income.” Although the income from a direct investment in Spot Bitcoin ETPs is not treated as qualifying income, the income generated from the Fund’s options on a Bitcoin index that uses one or more Spot Bitcoin ETPs as the reference asset is considered qualifying income because the Spot Bitcoin ETPs comprising such index are considered securities for purposes of Section 851(b)(2)) of the Code. To the extent the IRS disagrees with this view, then the Fund may fail to qualify as a RIC under the Code. If, in any year, the Fund fails to qualify as a RIC and was ineligible to or was not able to cure such failure, the Fund would be taxed in the same manner as an ordinary corporation and subject to U.S. federal income tax on all its income at the fund level. The resulting taxes could substantially reduce the Fund’s net assets and the amount of income available for distribution. In addition, in order to requalify for taxation as a RIC, the Fund could be required to recognize unrealized gains, pay substantial taxes and interest, and make certain distributions. See “Options Risk” and “Derivatives Risk” below for additional risks regarding the Fund’s options strategy.

Bitcoin Futures ETF Risks. The Bitcoin Futures ETF does not invest directly in bitcoin. Accordingly, the performance of the Bitcoin Futures ETF should not be expected to match the performance of bitcoin. The Fund will have significant exposure to the Bitcoin Futures ETF through its options positions that utilize the Bitcoin Futures ETF as the reference asset. Accordingly, the Fund will subject to the risks of the Bitcoin Futures ETF, set forth below.

Bitcoin Futures Risk. The market for bitcoin futures contracts may be less developed, and potentially less liquid and more volatile, than more established futures markets. While the market has grown substantially since bitcoin futures contracts commenced trading, there can be no assurance that this growth will continue. The price for bitcoin futures contracts is based on a number of factors, including the supply of and the demand for bitcoin futures contracts. Market conditions and expectations, position limits, accountability levels, collateral requirements, availability of counterparties, and other factors each can impact the supply of and demand for bitcoin futures contracts. Additionally, due to the high margin requirements that are unique to bitcoin futures contracts, the Bitcoin Futures ETF may experience difficulty maintaining the desired level of exposure to bitcoin futures contracts. If the Bitcoin Futures ETF is unable to achieve such exposure it may not be able to meet its investment objective and the Bitcoin Futures ETF’s returns may be different or lower than expected. Additionally, collateral requirements may require the Bitcoin Futures ETF to liquidate its positions, potentially incurring losses and expenses, when it otherwise would not do so. Investing in derivatives like bitcoin futures contracts may be considered aggressive and may expose the Bitcoin Futures ETF to significant risks. These risks include counterparty risk and liquidity risk.

Any disruption in the Bitcoin Futures ETF’s ability to obtain exposure to bitcoin futures contracts will cause the fund’s performance to deviate from the performance of bitcoin futures contracts, and consequently, bitcoin. Additionally, the ability of the Bitcoin Futures ETF to obtain exposure to bitcoin futures contracts is limited by certain tax rules that limit the amount the Bitcoin Futures ETF can invest in its wholly-owned subsidiary as of the end of each tax quarter.

Cost of Futures Investment Risk. When a bitcoin futures contract is nearing expiration, the Bitcoin Futures ETF will “roll” the futures contract, which means it will generally sell the bitcoin futures contract and use the proceeds to buy a bitcoin futures contract with a later expiration date. When rolling futures contracts that are in contango, the Bitcoin Futures ETF would sell a lower priced, expiring contract and purchase a higher priced, longer-dated contract. The price difference between the expiring contract and longer-dated contract associated with rolling futures contracts is typically substantially higher than the price difference associated with rolling other futures contracts. Bitcoin futures contracts have historically experienced extended periods of contango. Contango in the bitcoin futures contracts market may have a significant adverse impact on the performance of the Bitcoin Futures ETF and may cause bitcoin futures contracts, and the Bitcoin Futures ETF, to underperform the current price of bitcoin. Both contango and backwardation would reduce the Bitcoin Futures ETF’s correlation to the current price of bitcoin and may limit or prevent the Bitcoin Futures ETF from achieving its investment objective.

Clearing Broker Risk. The Bitcoin Future ETF’s investments in exchange-traded futures contracts expose it to the risks of a clearing broker (or an FCM). Under current regulations, a clearing broker or FCM maintains customers’ assets in a bulk segregated account. There is a risk that the assets of the Bitcoin Futures ETF deposited with the clearing broker to serve as margin may be used to satisfy the broker’s own obligations or the losses of the broker’s other clients. In the event of default, the Bitcoin Futures ETF could experience lengthy delays in recovering some or all of its assets and may not see any recovery at all. Furthermore, the Bitcoin Futures ETF is subject to the risk that no FCM is willing or able to clear the Fund’s transactions or maintain the Bitcoin Futures ETF’s assets. If the Bitcoin Futures ETF’s FCMs are unable or unwilling to clear the Bitcoin Futures ETF’s transactions, or if the FCM refuses to maintain the Bitcoin Futures ETF’s assets, the Bitcoin Futures ETF will be unable have its orders for bitcoin futures contracts fulfilled or assets custodied. In such a circumstance, the performance of the Bitcoin Futures ETF will likely deviate from the performance of bitcoin and may result in the proportion of bitcoin futures contracts in the Bitcoin Futures ETF’s portfolio relative to the total assets of the Bitcoin Futures ETF to decrease.

Commodity Regulatory Risk. The Bitcoin Futures ETF’s use of commodities futures subject to regulation by the CFTC has caused the Bitcoin Futures ETF to be classified as a “commodity pool” and this designation requires that the Bitcoin Futures ETF comply with CFTC rules, which may impose additional regulatory requirements and compliance obligations. The Bitcoin Futures ETF’s investment decisions may need to be modified, and commodity contract positions held by the Bitcoin Futures ETF may have to be liquidated at disadvantageous times or prices, to avoid exceeding any applicable position limits established by the CFTC, potentially subjecting the Bitcoin Futures ETF to substantial losses. The regulation of commodity transactions in the United States is subject to ongoing modification by government, self-regulatory and judicial action. The effect of any future regulatory change with respect to any aspect of the Bitcoin Futures ETF is impossible to predict, but could be substantial and adverse to the Bitcoin Futures ETF.

Digital Asset Industry Risk. The digital asset industry is a new, speculative, and still-developing industry that faces many risks. In this emerging environment, events that are not directly related to the security or utility of the Bitcoin blockchain can nonetheless precipitate a significant decline in the price of bitcoin. For instance, in May 2022, the collapse of the algorithmic stablecoin TerraUSD and its paired crypto asset LUNA destroyed an estimated $60 billion in value in the crypto ecosystem. Although TerraUSD and LUNA operated on their own blockchain (the “Terra” blockchain), the events nonetheless contributed to a sharp decline in the price of bitcoin, which fell 16% from May 1, 2022 to May 31, 2022. As another example, in November 2022, FTX Trading Ltd. – an offshore digital asset trading venue specializing in crypto derivatives – collapsed and filed for bankruptcy. While a small fraction of total global trading volume in bitcoin and related derivatives took place on FTX-related venues, the company’s collapse nonetheless contributed to a significant decline in the price of bitcoin, which fell 16% in November 2022. Additional instability, failures, bankruptcies or other negative events in the digital asset industry, including events that are not necessarily related to the security or utility of the Bitcoin blockchain, could similarly negatively impact the price of bitcoin, and thereby the bitcoin futures contracts held by the Bitcoin Futures ETF.

Such occurrences could also impair the Bitcoin Futures ETF’s ability to meet its investment objective pursuant to its investment strategy.

Futures Contracts Risk. Risks of futures contracts include: (i) an imperfect correlation between the value of the futures contract and the underlying asset; (ii) possible lack of a liquid secondary market; (iii) the inability to close a futures contract when desired; (iv) losses caused by unanticipated market movements, which may be unlimited; (v) an obligation for the Bitcoin Futures ETF to make daily cash payments to maintain its required margin, particularly at times when the Bitcoin Futures ETF may have insufficient cash; and (vi) unfavorable execution prices from rapid selling. Unlike equities, which typically entitle the holder to a continuing stake in a corporation, futures contracts normally specify a certain date for settlement in cash based on the reference asset. As the futures contracts approach expiration, they may be replaced by similar contracts that have a later expiration. This process is referred to as “rolling.” If the market for these contracts is in “contango,” meaning that the prices of futures contracts in the nearer months are lower than the price of contracts in the distant months, the sale of the near-term month contract would be at a lower price than the longer-term contract, resulting in a cost to “roll” the futures contract. The actual realization of a potential roll cost will be dependent upon the difference in price of the near and distant contract. The costs associated with rolling bitcoin futures contracts may have a significant adverse impact on the performance of the Bitcoin Futures ETF.

 

NEOS Bitcoin High Income ETF | Market and Volatility Risk [Member]

Risk [Text Block]

Market and Volatility Risk. The prices of bitcoin and bitcoin futures contracts have historically been highly volatile. The value of bitcoin has been, and may continue to be, substantially dependent on speculation, such that trading and investing in these assets generally may not be based on fundamental analysis. The value of the Bitcoin Future ETF’s investments in bitcoin futures contracts – and therefore the value of an investment in the Bitcoin Futures ETF – could decline significantly and without warning, including to zero.

Risk [Text Block]

Reverse Repurchase Agreements Risk. Reverse repurchase agreements involve both counterparty risk and the risk that the value of securities that the Bitcoin Futures ETF is obligated to repurchase under the agreement may decline below the repurchase price. Reverse repurchase agreements involve leverage risk; the Bitcoin Futures ETF may lose money as a result of declines in the values both of the security subject to the reverse repurchase agreement and the instruments in which the Bitcoin Futures ETF invested the proceeds of the reverse repurchase agreement.

Risk [Text Block]

Trading Halt Risk. Trading in shares of the Bitcoin Futures ETF on U.S. securities exchanges may be halted due to market conditions or for reasons that, in the view of an exchange, make trading in shares of the Bitcoin Futures ETF inadvisable. In addition, trading of shares of the Bitcoin Futures ETF on securities exchanges is subject to trading halts caused by extraordinary market volatility pursuant to an exchange’s “circuit breaker” rules. Shares of the Bitcoin Futures ETF may be at a higher risk of a trading halt due to the volatility of bitcoin. In the event that shares of the Bitcoin Futures ETF are subject to a trading halt, the Fund’s ability to pursue its principal investment strategy may be impaired and the Fund may be negatively affected.

Subsidiary Investment Risk. Changes in the laws of the United States and/or the Cayman Islands, under which a Bitcoin Futures ETF and its wholly-owned Cayman subsidiary are organized, respectively, could result in the inability of the Bitcoin Futures ETF to operate as intended and could negatively affect the Bitcoin Futures ETF and its shareholders (such as the Fund). The Bitcoin Futures ETF’s Cayman subsidiary is not registered under the 1940 Act and is not subject to all the investor protections of the 1940 Act.

 

NEOS Bitcoin High Income ETF | FLEX Options Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

FLEX Options Risk. Trading FLEX Options involves risks different from, or possibly greater than, the risks associated with investing directly in securities. The Fund may experience losses from specific FLEX Option positions and certain FLEX Option positions may expire worthless. The FLEX Options are listed and trade on an exchange; however, no one can guarantee that a liquid secondary trading market will exist for the FLEX Options. In the event that trading in the FLEX Options is limited or absent, the value of the Fund’s FLEX Options may decrease. In a less liquid market for the FLEX Options, liquidating the FLEX Options may require the payment of a premium (for written FLEX Options) or acceptance of a discounted price (for purchased FLEX Options) and may take longer to complete. A less liquid trading market may adversely impact the value of the FLEX Options and Fund shares and result in the Fund being unable to achieve its investment objective. Less liquidity in the trading of the Fund’s FLEX Options could have an impact on the prices paid or received by the Fund for the FLEX Options in connection with creations and redemptions of the Fund’s shares. Depending on the nature of this impact to pricing, the Fund may be forced to pay more for redemptions (or receive less for creations) than the price at which it currently values the FLEX Options. Such overpayment or under collection could reduce the Fund’s ability to achieve its investment objective. Additionally, in a less liquid market for the FLEX Options, the liquidation of a large number of options may more significantly impact the price. A less liquid trading market may adversely impact the value of the FLEX Options and the value of your investment. The trading in FLEX Options may be less deep and liquid than the market for certain other exchange-traded options, non-customized options or other securities.

 

NEOS Bitcoin High Income ETF | Leverage Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Leverage Risk. While the Fund does not seek leveraged exposure to Bitcoin, the Fund seeks to achieve and maintain the exposure to the price of the Bitcoin by using the leverage inherent in options contracts. Therefore, the Fund is subject to leverage risk. When the Fund purchases or sells an instrument or enters into a transaction without investing an amount equal to the full economic exposure of the instrument or transaction, it creates leverage, which can result in the Fund losing more than it originally invested. As a result, these investments may magnify losses to the Fund, and even a small market movement may result in significant losses to the Fund. Leverage may also cause the Fund to be more volatile because it may exaggerate the effect of any increase or decrease in the value of the Fund’s portfolio securities. Options trading involves a degree of leverage and as a result, a relatively small price movement in futures instruments may result in immediate and substantial losses to the Fund.

 

NEOS Bitcoin High Income ETF | Rolling Options Contract Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Rolling Options Contract Risk. The Fund’s investments in options are subject to risks related to rolling. Rolling occurs when the Fund closes out of an options contract as it nears its expiration and replaces it with a contract that has a later expiration. The Fund does not intend to hold options through expiration, but instead intends to “roll” its positions. When the market for these options is such that the prices are higher in the more distant delivery months than in the nearer delivery months, the sale during the course of the “rolling process” of the more nearby contract would take place at a price that is lower than the price of the more distant contract. This pattern of higher option prices for longer expiration contracts is often referred to as “contango.” Alternatively, when the market for options contracts is such that the prices are higher in the nearer months than in the more distant months, the sale during the course of the “rolling process” of the more nearby contract would take place at a price that is higher than the price of the more distant contract. This pattern of higher options prices for shorter expiration options contracts is referred to as “backwardation.” Extended periods of contango or backwardation have occurred in the past and can in the future cause significant losses for the Fund.

Risk [Text Block]

Wholly-Owned Subsidiary Risk. Changes in the laws of the United States and/or the Cayman Islands, under which the Fund and the Subsidiary, respectively, are organized, could result in the inability of the Fund and/or Subsidiary to operate as described in this Prospectus and could negatively affect the Fund and its shareholders. The Subsidiary is not registered under the 1940 Act and, unless otherwise noted in this Prospectus, is not subject to all of the investor protections of the 1940 Act, such as limits on leverage when viewed in isolation from the Fund. Because the Fund wholly owns and controls the Subsidiary, and is overseen by the Adviser, it is unlikely that the Subsidiary will take action contrary to the interests of the Fund or its shareholders.

 

NEOS Bitcoin High Income ETF | Taxation Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Taxation Risk. By investing in certain Spot Bitcoin ETPs indirectly through the Subsidiary, the Fund will obtain exposure to these securities within the federal tax requirements that apply to the Fund. However, because the Subsidiary is a controlled foreign corporation, any income received from its investments will be passed through to the Fund as ordinary income, which may be taxed at less favorable rates than capital gains. Exceeding this amount may have tax consequences. In order to qualify for the special tax treatment accorded a RIC and its shareholders, the Fund must derive at least 90% of its gross income for each taxable year from “qualifying income,” meet certain asset diversification tests at the end of each taxable quarter, and meet annual distribution requirements. The Fund’s pursuit of its investment strategy will potentially be limited by the Fund’s intention to qualify for such treatment and could adversely affect the Fund’s ability to so qualify. The Fund expects to gain exposure to bitcoin and generate qualifying income by investing a portion of its assets in a wholly-owned subsidiary of the Fund organized under the laws of the Cayman Islands. To comply with the asset diversification test applicable to a RIC, the Fund will limit its investments in such subsidiary to 25% of the Fund’s total assets at the end of each tax quarter. The Fund may, however, exceed this amount from time to time inadvertently or if the Adviser believes doing so is in the best interests of the Fund, provided, however, that the Fund intends to continue to comply with the asset diversification test applicable to RICs. If the Fund’s investments in the subsidiary were to exceed 25% of the Fund’s total assets at the end of a tax quarter, the Fund may no longer be eligible to be treated as a RIC. The Adviser will carefully monitor the Fund’s investments in the subsidiary to ensure that no more than 25% of the Fund’s assets are invested in the subsidiary at the end of each tax quarter. There are no assurances that the IRS will agree with the Fund’s calculation under the asset diversification test which could cause the Fund to fail to qualify as a RIC. If, in any year, the Fund were to fail to qualify for the special tax treatment accorded a RIC and its shareholders, and were ineligible to or were not to cure such failure, the Fund would be taxed in the same manner as an ordinary corporation subject to U.S. federal income tax on all its income at the fund level. The resulting taxes could substantially reduce the Fund’s net assets and the amount of income available for distribution. In addition, in order to requalify for taxation as a RIC, the Fund could be required to recognize unrealized gains, pay substantial taxes and interest, and make certain distributions.

Active Management Risk. The Fund is actively managed, which means that investment decisions are made based on investment views. There is no guarantee that the investment views will produce the desired results or expected returns, which may cause the Fund to fail to meet its investment objective or to underperform its benchmark index or funds with similar investment objectives and strategies. Furthermore, active trading that can accompany active management may result in high portfolio turnover, which may have a negative impact on performance. Active trading may result in higher brokerage costs or mark-up charges, which are ultimately passed on to shareholders of the Fund. Active trading may also result in adverse tax consequences.

 

NEOS Enhanced Income 20+ Year Treasury Bond ETF | Derivatives Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Derivatives Risk. The Fund’s use of derivatives may reduce the Fund’s returns or increase volatility. Volatility is defined as the characteristic of a security, an index or a market to fluctuate significantly in price within a short time period. Derivatives may also be subject to counterparty risk, which is the risk that the other party in the transaction will not fulfill its contractual obligation. Counterparty risk for over-the-counter (“OTC”) derivatives is generally higher than that for derivatives traded on an exchange or through a clearing house. A risk of the Fund’s use of derivatives is that the fluctuations in their values may not correlate perfectly with the value of the underlying asset, the performance of the asset class to which the Fund seeks exposure or the performance of the overall markets. The possible lack of a liquid secondary market for derivatives and the resulting inability of the Fund to sell or otherwise close a derivatives position could expose the Fund to losses and could make derivatives more difficult for the Fund to value accurately. The Fund could also suffer losses related to its derivatives positions as a result of unanticipated market movements, or movements between the time of periodic reallocations of Fund assets, which losses are potentially unlimited. Certain derivatives may give rise to a form of leverage and may expose the Fund to greater risk and increase its costs. The impact of U.S. and global regulation of derivatives may make derivatives more costly, may limit the availability of derivatives, may delay or restrict the exercise by the Fund of termination rights or remedies upon a counterparty default under derivatives held by the Fund (which could result in losses), or may otherwise adversely affect the value or performance of derivatives.

Exchange Traded Funds (“ETFs”) Risk. The Fund is structured as an ETF. As a result, the Fund is subject to special risks, including:

 

NEOS Enhanced Income 20+ Year Treasury Bond ETF | Not Individually Redeemable [Member]  
Prospectus [Line Items]  
Risk [Text Block]
●Not Individually Redeemable. The Fund’s shares (“Shares”) are not redeemable by retail investors and may be redeemed only by Authorized Participants at net asset value (“NAV”) and only in Creation Units. A retail investor generally incurs brokerage costs when selling shares.

 

NEOS Enhanced Income 20+ Year Treasury Bond ETF | Trading Issues [Member]  
Prospectus [Line Items]  
Risk [Text Block]
●Trading Issues. Trading in Shares on the Exchange may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in Shares inadvisable, such as extraordinary market volatility. There can be no assurance that Shares will continue to meet the listing requirements of the Exchange which may result in the Shares being delisted. An active trading market for the Shares may not be developed or maintained. If the Shares are traded outside a collateralized settlement system, the number of financial institutions that can act as Authorized Participants that can post collateral on an agency basis is limited, which may limit the market for the Shares.

 

NEOS Enhanced Income 20+ Year Treasury Bond ETF | Market Price Variance Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]
●Market Price Variance Risk. The market prices of Shares will fluctuate in response to changes in NAV and supply and demand for Shares and will include a “bid-ask spread” charged by the exchange specialists, market makers or other participants that trade the Shares. There may be times when the market price and the NAV vary significantly. This means that Shares may trade at a discount to NAV.

 

○In times of market stress, market makers may step away from their role market making in the Shares and in executing trades, which can lead to differences between the market value of the Shares and the Fund’s NAV.

 

○The market price of the Shares may deviate from the Fund’s NAV, particularly during times of market stress, with the result that investors may pay significantly more or significantly less for the Shares than the Fund’s NAV, which is reflected in the bid and ask price for the Shares or in the closing price.

 

○In stressed market conditions, the market for the Shares may become less liquid in response to the deteriorating liquidity of the Fund’s portfolio. This adverse effect on the liquidity of the Shares may, in turn, lead to differences between the market value of the Shares and the Fund’s NAV.

 

NEOS Enhanced Income 20+ Year Treasury Bond ETF | Authorized Participant Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]
●Authorized Participant Risk. Only an Authorized Participant may engage in creation or redemption transactions directly with the Fund. The Fund has a limited number of institutions that may act as an Authorized Participant on an agency basis (i.e., on behalf of other market participants). To the extent that Authorized Participants exit the business or are unable to proceed with creation or redemption orders with respect to the Fund and no other Authorized Participant is able to step forward to create or redeem Creation Units, Fund shares may be more likely to trade at a premium or discount to net asset value and possibly face trading halts or delisting. Authorized Participant concentration risk may be heightened for securities or instruments that have lower trading volumes.

 

Additionally, purchases and redemptions of creation units primarily with cash rather than through in-kind delivery of portfolio securities may cause the Fund to incur certain costs, including brokerage costs or taxable gains or losses that it might not have incurred if it made a redemption in-kind, and therefore decrease the Fund’s NAV to the extent not offset by a transaction fee payable by an AP.

Prospectus [Line Items]

Issuer Risk. Changes in the financial condition or credit rating of an issuer or counterparty, changes in specific economic or political conditions that affect a particular type of security or issuer, and changes in general economic or political conditions can affect a security’s or instrument’s value. The values of securities of smaller, less well-known issuers can be more volatile than those of larger issuers. Issuer-specific events can have a negative impact on the value of the Fund.

 

NEOS Enhanced Income 20+ Year Treasury Bond ETF | Market and Geopolitical Risk [Member]

Market and Geopolitical Risk. The increasing interconnectivity between global economies and financial markets increases the likelihood that events or conditions in one region or financial market may adversely impact issuers in a different country, region or financial market. Securities in the Fund’s portfolio may underperform due to inflation (or expectations for inflation), interest rates, global demand for particular products or resources, natural disasters, climate change and climate-related events, pandemics, epidemics, terrorism, international conflicts, regulatory events and governmental or quasi-governmental actions. The occurrence of global events similar to those in recent years may result in market volatility and may have long term effects on financial markets worldwide.

Options Risk. There are risks associated with the sale and purchase of put options. As a seller (writer) of a put option, the Fund will tend to lose money if the value of the reference index or security falls below the strike price. As the buyer of a put option, the Fund risks losing the entire premium invested in the option if the Fund does not exercise the option.

 

NEOS Enhanced Income 20+ Year Treasury Bond ETF | Tax Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Tax Risk. The Fund invests in derivatives. The federal income tax treatment of a derivative may not be as favorable as a direct investment in an underlying asset. Derivatives may produce taxable income and taxable realized gain. Derivatives may adversely affect the timing, character and amount of income the Fund realizes from its investments. As a result, a larger portion of the Fund’s distributions may be treated as ordinary income rather than as capital gains. In addition, certain derivatives are subject to mark-to-market or straddle provisions of the Internal Revenue Code of 1986, as amended (the “Internal Revenue Code”). If such provisions are applicable, there could be an increase (or decrease) in the amount of taxable dividends paid by the Fund.

 

NEOS Enhanced Income 20+ Year Treasury Bond ETF | Valuation Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Valuation Risk. The price the Fund could receive upon the sale of a security or other asset may differ from the Fund’s valuation of the security or other asset, particularly for securities or other assets that trade in low volume or volatile markets or that are valued using a fair value methodology as a result of trade suspensions or for other reasons. In addition, the value of the securities or other assets in the Fund’s portfolio may change on days or during time periods when shareholders will not be able to purchase or sell the Fund’s shares. Authorized Participants who purchase or redeem Fund shares on days when the Fund is holding fair-valued securities may receive fewer or more shares, or lower or higher redemption proceeds, than they would have received had the Fund not fair- valued securities or used a different valuation methodology. The Fund’s ability to value investments may be impacted by technological issues or errors by pricing services or other third- party service providers.

Risk [Text Block]

Credit Risk. Debt issuers and other counterparties may be unable or unwilling to make timely interest and/or principal payments when due or otherwise honor their obligations. Changes in an issuer’s credit rating or the market’s perception of an issuer’s creditworthiness may also adversely affect the value of the Fund’s investment in that issuer. The degree of credit risk depends on an issuer’s or counterparty’s financial condition and on the terms of an obligation.

 

NEOS Enhanced Income 20+ Year Treasury Bond ETF | Forward Contract Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Forward Contract Risk. Forward contracts involve the purchase or sale of a specific quantity of a government security at a specified price, with delivery and settlement at a specified future date. Forward contracts, unlike futures contracts, are not traded on exchanges and are not standardized; rather, banks and dealers act as principals in these markets, negotiating each transaction on an individual basis. The principals who deal in the forward markets are not required to continue to make markets in the currencies or commodities they trade and these markets can experience periods of illiquidity, sometimes of significant duration. There have been periods during which certain participants in these markets have refused to quote prices for certain currencies or commodities or have quoted prices with an unusually wide spread between the price at which they were prepared to buy and that at which they were prepared to sell.

 

NEOS Enhanced Income 20+ Year Treasury Bond ETF | Futures Contract Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Futures Contract Risk. Futures are standardized, exchange-traded contracts that obligate a purchaser to take delivery, and a seller to make delivery, of a specific amount of an asset at a specified future date at a specified price. Unlike equities, which typically entitle the holder to a continuing ownership stake in an issuer, futures contracts normally specify a certain date for settlement in cash based on the level of the reference rate. The primary risks associated with the use of futures contracts, or swaps or other derivatives referencing futures contracts, are: (i) the imperfect correlation between the change in market value of the instruments held by the Fund and the price of the futures contract; (ii) possible lack of a liquid secondary market for a futures contract and the resulting inability to close a futures contract when desired; (iii) losses caused by unanticipated market movements, which are potentially unlimited; (iv) the Adviser’s inability to predict correctly the direction of prices and other economic factors; and (v) the possibility that the counterparty will default in the performance of its obligations.

Prospectus [Line Items]  
Risk [Text Block]

Underlying ETF and Index Risk. The Fund may have exposure to underlying ETFs that track their respective indexes. Because the value of the Fund in part will be based on the value of the Underlying ETF, the Fund’s investment performance depends on the investment performance and associated risks of the Underlying ETFs. The Underlying ETFs are subject to many of the same structural risks as the Fund that are described in more detail herein, such Exchange-Traded Fund Risk.

 

NEOS Enhanced Income 20+ Year Treasury Bond ETF | U.S. Treasury Market Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

U.S. Treasury Market Risk. The U.S. Treasury market can be volatile, and the value of instruments correlated with these markets may fluctuate dramatically from day to day. U.S. Treasury obligations may provide relatively lower returns than those of other securities. U.S. Treasury obligations may differ from other securities in their interest rates, maturities, times of issuance and other characteristics and may provide relatively lower returns than those of other securities. U.S. Treasury obligations are backed by the “full faith and credit” of the U.S. government and generally have negligible credit risk. Securities issued or guaranteed by federal agencies or authorities and U.S. government-sponsored instrumentalities or enterprises may or may not be backed by the full faith and credit of the U.S. government. Similar to other issuers, changes to the financial condition or credit rating of the U.S. government may cause the value of the U.S. Treasury obligations held by the Fund to decline.

 

NEOS Enhanced Income 20+ Year Treasury Bond ETF | Fixed Income Securities Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Fixed Income Securities Risk. Fixed income risk factors include credit risk (the debtor may default) and prepayment risk (the debtor may pay its obligation early or later than expected, potentially reducing the amount of interest payments or extending time to principal repayment). These risks could affect the value of a particular investment possibly causing the Fund’s share price and total return to be reduced and fluctuate more than other types of investments. When the Fund invests in fixed income securities the value of your investment in a Fund will fluctuate with changes in interest rates. Typically, a rise in interest rates causes a decline in the value of fixed income securities. Since the Fund primarily invests in fixed-income securities with remaining maturities of greater than or equal to 20 years, such fixed-income securities will have greater sensitivity to increases or decreases in interest rates than investments in shorter-term securities. If the U.S. Federal Reserve’s Federal Open Market Committee (“FOMC”) raises the federal funds interest rate target, interest rates across the U.S. financial system may rise. However, the magnitude of rate changes across maturities and borrower sectors is uncertain. Rising rates may decrease liquidity and increase volatility, which may make portfolio management more difficult and costly to the Fund and its shareholders. Additionally, default risk increases if issuers must borrow at higher rates. Generally, these changing market conditions may cause the Fund’s share price to fluctuate or decline more than other types of equity investments.

Exchange Traded Funds (“ETFs”) Risk: An investment in an ETF is subject to the risk that the general level of security prices, or that the prices of securities within a particular sector, may increase or decline, thereby affecting the value of the shares of an ETF. In addition, ETFs are subject to the following risks: (1) the market price of the ETF’s shares may trade at a discount to its net asset value (“NAV”) due to the fact that the supply and demand in the market for ETF shares at any point in time is not always identical to the supply and demand in the market for the ETF’s underlying basket of securities, accordingly, there may be times when an ETF trades at a premium (creating the risk that the Fund pays more than NAV for an ETF when making a purchase) or discount (creating the risks that the Fund’s NAV is reduced for undervalued ETFs it holds, and that the Fund receives less than NAV when selling an ETF); (2) an active trading market for an ETF’s shares may not develop or be maintained; (3) trading of an ETF’s shares may be halted if the listing exchange deems such action appropriate; (4) ETF shares may be delisted from the exchange on which they trade; (5) activation of “circuit breakers” by the exchange (which are tied to large decreases in stock prices) may halt trading of the ETF temporarily; and (6) purchases and redemptions of creation units primarily with cash rather than through in-kind delivery of portfolio securities may cause the Fund to incur certain costs, including brokerage costs or taxable gains or losses that it might not have incurred if it made a redemption in-kind, and therefore decrease the Fund's NAV to the extent not offset by a transaction fee payable by an AP.

Credit Risk: Credit risk is the risk that the issuer of a debt security (including corporate, government and mortgage- backed securities) will be unable or unwilling to make timely principal and/or interest payments, or otherwise will be unable or unwilling to honor its financial obligations. If the issuer fails to pay interest, the Fund’s income will be reduced. If the issuer fails to repay principal, the value of that debt security and of the Fund’s shares may be reduced. To the extent the Fund invests in lower rated debt securities (such as High Yield Securities), the Fund will be subject to a higher level of credit risk than a fund that invests only in the highest rated debt securities.

Consequently, changes in interest rates may have a significant effect on the Fund, especially if the Fund is holding a significant portion of its assets in debt securities that are particularly sensitive to interest rate fluctuations, such as debt securities with long-term maturities, zero coupon bonds, and debentures. A rise or potential rise in interest rates may cause the Fund to lose value and increase redemptions, which could require the Adviser to liquidate portfolio securities at disadvantageous prices and times, resulting in losses to the Fund.

Prospectus [Line Items]  
Risk [Text Block]

Prepayment Risk: Issuers of debt securities in which the Fund may invest may be able to prepay principal due on these securities. Declining interest rates may encourage issuers to pay off their debt obligations sooner than expected. This can reduce the effective maturity of the debt security and lower returns to the Fund, especially if the Fund reinvests its assets at a lower prevailing interest rate.

 

NEOS Enhanced Income Credit Select ETF | U.S. Government Securities Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

U.S. Government Securities Risk: Securities issued by the U.S. government, or its agencies are subject to risks related to the creditworthiness of the U.S. government. In addition, such securities may not be backed by the “full faith and credit” of the U.S. government, but rather by a right to borrow from the U.S. government or the creditworthiness of the issuer itself. The value of any such securities may fluctuate with changes in credit ratings and market perceptions of the U.S. government and the issuers of the securities, as well as interest rates and other risks applicable to fixed-income securities generally.

 

NEOS Enhanced Income Credit Select ETF | Authorized Participants, Market Makers, and Liquidity Providers Concentration Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Authorized Participants, Market Makers, and Liquidity Providers Concentration Risk: The Fund has a limited number of financial institutions that may act as Authorized Participants (“APs”). In addition, there may be a limited number of market makers and/or liquidity providers in the marketplace. To the extent either of the following events occur, Shares may trade at a material discount to NAV and possibly face delisting: (i) APs exit the business or otherwise become unable to process creation and/or redemption orders and no other APs step forward to perform these services, or (ii) market makers and/or liquidity providers exit the business or significantly reduce their business activities and no other entities step forward to perform their functions.

Risk [Text Block]

Shares May Trade at Prices Other Than NAV Risk:  As with all ETFs, Shares may be bought and sold in the secondary market at market prices. Although it is expected that the market price of Shares will approximate the Fund’s NAV, there may be times when the market price of Shares is more than the NAV intra-day (premium) or less than the NAV intra-day (discount) due to supply and demand of Shares or during periods of market volatility. This risk is heightened in times of market volatility, periods of steep market declines, and periods when there is limited trading activity for Shares in the secondary market, in which case such premiums or discounts may be significant.

 

NEOS Enhanced Income Credit Select ETF | Underlying Investment Company Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Underlying Investment Company Risk: The Fund may invest in the securities of other investment companies including ETFs. If the Fund invests in and, thus, is a shareholder of, another investment company, the Fund’s shareholders will indirectly bear the Fund’s proportionate share of the fees and expenses paid by such other investment company, including advisory fees, in addition to both the management fees payable directly by the Fund to the Fund’s own investment adviser and the other expenses that the Fund bears directly in connection with the Fund’s own operations.

 

NEOS Enhanced Income Credit Select ETF | Market Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Market Risk: Market risk is the risk that the value of the securities in the Fund’s portfolio may decline due to daily fluctuations in the securities markets that are generally beyond the Adviser’s control, including fluctuation in interest rates, the quality of the Fund’s investments, economic conditions and general bond market conditions. The increasing interconnectivity between global economies and financial markets increases the likelihood that events or conditions in one region or financial market may adversely impact issuers in a different country, region or financial market. Securities in the Fund’s portfolio may underperform due to inflation (or expectations for inflation), interest rates, global demand for particular products or resources, natural disasters, climate change and climate-related events, pandemics, epidemics, terrorism, international conflicts, regulatory events and governmental or quasi-governmental actions. The occurrence of global events similar to those in recent years may result in market volatility and may have long term effects on financial markets worldwide. During periods of market volatility, security prices (including securities held by the Fund) could fall drastically and rapidly and, therefore, adversely affect the Fund, and you could lose money over short- or long-term periods.

 

NEOS Enhanced Income Credit Select ETF | Investment Model Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Investment Model Risk: The share price of the Fund changes daily based on the performance of the securities in which it invests, the selection of which are determined primarily by the Model. The ability of the Fund to meet its investment objective is directly related to the ability of the Model to accurately measure market risk or volatility and appropriately react to current and developing market trends. There can be no assurance that the use of the Model will enable the Fund to achieve positive returns or outperform the market. If the Model and Adviser fail to accurately evaluate market risk or appropriately react to current and developing market conditions, the Fund’s share price may be adversely affected.

 

NEOS Enhanced Income Credit Select ETF | Risks Related to “Fund of Funds” Structure [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Risks Related to “Fund of Funds” Structure: Investments in ETFs subject the Fund to paying its proportionate share of fees and expenses from those investments. In addition, under the Investment Company Act of 1940, as amended (the “1940 Act”), the Fund is subject to restrictions that may limit the amount of any particular ETF that the Fund may own.

 

Since the Fund is a “fund of funds,” your cost of investing in the Fund will generally be higher than the cost of investing directly in ETFs. By investing in the Fund, you will indirectly bear fees and expenses charged by the underlying ETFs in which the Fund invests in addition to the Fund’s direct fees and expenses. Furthermore, the use of a fund of funds structure could affect the timing, amount, and character of the Fund’s distributions and therefore may increase the amount of your tax liability.

 

ETFs that the Fund may invest in are subject to the risks of the underlying securities or sectors the ETF is designed to track. ETFs may be actively managed or indexed-based. Actively managed ETFs are subject to management risk and may not achieve their objective if the ETF’s manager’s expectations regarding particular securities or markets are not met. An index-based ETF’s objective is to track the performance of a specific index. Index- based ETFs generally invest in a securities portfolio that includes substantially all of the securities (in substantially the same amount) included in the applicable index. Since passively managed ETFs are designed to track an index, securities may be purchased, retained and sold when an actively managed ETF would not do so. As a result, passively managed ETFs can expect greater risk of loss (and a corresponding prospect of gain) from changes in the value of the securities that are heavily weighted in the index than would be the case if the ETF were not fully invested in such securities.

 

NEOS Enhanced Income Credit Select ETF | Corporate Debt Securities Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Corporate Debt Securities Risk: The Fund’s debt securities investments may directly or indirectly include corporate debt securities. Corporate debt obligations purchased by the Fund may be any credit quality, maturity or yield. Accordingly, the Fund’s debt securities may include “investment grade” securities (those rated at least Baa by Moody’s, BBB by S&P or Fitch or, if not rated, of equivalent quality in the Adviser’s opinion). In addition, the Fund’s debt securities may include lower-rated debt securities including, without limitation, high-yield and/or junk bonds rated below Baa by Moody’s or BBB by S&P’s or Fitch (see “Junk Bonds or Lower-Rated Securities Risk” below). The Fund’s fixed-income securities investments are subject to risks of non-payment of interest and principal, the risk that bond demand in the marketplace will decrease periodically, and the risk that ratings of the various credit services (and the Adviser’s independent assessments of the securities’ creditworthiness) are or may become inaccurate.

 

NEOS Enhanced Income Credit Select ETF | Cash Transaction Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Cash Transaction Risk: Unlike most exchange-traded funds (“ETFs”), the Fund intends to effect a significant portion of creations and redemptions for cash, rather than in-kind securities. As a result, an investment in the Fund may be less tax-efficient than an investment in a more conventional ETF. Moreover, cash transactions may have to be carried out over several days if the securities market is relatively illiquid and may involve considerable brokerage fees and taxes. These factors may result in wider spreads between the bid and the offered prices of the Fund’s Shares than for more conventional ETFs.

 

NEOS Enhanced Income Credit Select ETF | Junk Bonds or Lower-Rated Securities Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Junk Bonds or Lower-Rated Securities Risk: Debt securities rated below Baa by Moody’s or BBB by S&P or Fitch are generally considered speculative in nature and are generally subject to greater risks with respect to the non-payment of interest and principal and greater market fluctuations than higher-rated debt securities. Lower-rated debt securities are usually issued by companies without long track records of sales and earnings, or by companies with questionable credit strength. These debt securities are considered below “investment-grade.” The retail secondary market for these “junk bonds” may be less liquid than that of higher-rated debt securities, and adverse conditions could make it difficult at times to sell certain securities or could result in lower prices than those used in calculating the Fund’s net asset value. These risks can reduce the value of the Fund’s shares and the income it earns.

 

NEOS Enhanced Income Credit Select ETF | Liquidity Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Liquidity Risk: Liquidity risk is the risk that the Fund may not be able to sell a particular investment at an advantageous time or price or at all. For example, if a debt security is downgraded or drops in price, the market demand for such security may be limited, making the security difficult to sell. Additionally, the market for certain securities may become illiquid under adverse market or economic conditions. Investments in debt securities, including below investment grade securities, tend to involve greater liquidity risk.

 

NEOS Enhanced Income Credit Select ETF | Maturity Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Maturity Risk: Maturity risk is another factor that can affect the value of the Fund’s debt security holdings. In general, but not in all cases, the longer the maturity of a debt security, the higher its yield and the greater its price sensitivity to changes in interest rates. Conversely, the shorter the maturity, the lower the yield but the greater the price stability. The Fund will be subject to greater maturity risk to the extent it is invested in debt securities with longer maturities.

Prospectus [Line Items]  
Risk [Text Block]

Regional and Sector Risk: Regional and sector risk is the risk that if the Fund invests heavily in securities within the same state, region, currency, industry or economic sector, an adverse economic, business or political development may affect the value of the Fund’s investments more than if its investments were not so focused. To the extent the Fund invests heavily in securities in any such area that experiences an adverse development, the value of the Fund’s portfolio may be negatively affected.

 

NEOS Enhanced Income Credit Select ETF | Risks Related to Frequent Trading and Portfolio Turnover [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Risks Related to Frequent Trading and Portfolio Turnover: As a result of its trading strategies, the Fund may sell portfolio securities without regard to the length of time they have been held and will likely have a higher portfolio turnover rate than other funds. Since portfolio turnover may involve paying brokerage commissions and other transaction costs, higher turnover generally results in additional Fund expenses. High rates of portfolio turnover may lower the performance of the Fund due to these increased costs and may also result in the realization of short-term capital gains. If the Fund realizes capital gains when portfolio investments are sold, the Fund must generally distribute those gains to shareholders, increasing the Fund’s taxable distributions. High rates of portfolio turnover in a given year would likely result in short-term capital gains that are taxed to shareholders at ordinary income tax rates. Under normal circumstances, the anticipated annual portfolio turnover rate for the Fund is expected to be significantly greater than 100%.

Risk [Text Block]
●Derivatives Risk. The Fund invests in options that derive their performance from the performance of an underlying reference asset. Derivatives, such as the options in which the Fund invests, can be volatile and involve various types and degrees of risks, depending upon the characteristics of a particular derivative. Derivatives may have investment exposures that are greater than their cost would suggest, meaning that a small investment in a derivative could have a substantial impact on the performance of the Fund. The Fund could experience a loss if its derivatives do not perform as anticipated, the derivatives are not correlated with the performance of their reference asset, or if the Fund is unable to purchase or liquidate a position because of an illiquid secondary market. The market for many derivatives is, or suddenly can become, illiquid. Changes in liquidity may result in significant, rapid, and unpredictable changes in the prices for derivatives.

●Market and Geopolitical Risk. The prices of securities held by the Fund may decline in response to certain events taking place around the world, including those directly involving the companies whose securities are owned by the Fund; conditions affecting the general economy; overall market changes; local, regional or global political, social or economic instability; and currency, interest rate and commodity price fluctuations. The equity securities purchased by the Fund may involve large price swings and potential for loss. Investors in the Fund should have a long-term perspective and be able to tolerate potentially sharp declines in value. The value of your investment in the Fund is based on the market prices of the securities the Fund holds. These prices change daily due to economic and other events that affect markets generally, as well as those that affect particular regions, countries, industries, companies or governments.

○Information Technology Sector Risk. Market or economic factors impacting information technology companies and companies that rely heavily on technological advances could have a significant effect on the value of the Fund’s investments. The value of stocks of information technology companies and companies that rely heavily on technology is particularly vulnerable to rapid changes in technology product cycles, rapid product obsolescence, government regulation and competition, both domestically and internationally, including competition from foreign competitors with lower production costs. Information technology companies are heavily dependent on patent and intellectual property rights, the loss or impairment of which may adversely affect profitability.

 

NEOS Nasdaq-100(R) Hedged Equity Income ETF | Tax Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]
●Tax Risk. The Fund expects to generate premiums from its sale of call options. These options are expected to result in capital gains or losses for federal income tax purposes and may be subject to mark-to-market rules. These gains or losses will be wholly or partly long-term or short-term depending on the nature of the options sold by the Fund and will take into account premiums generated. In addition, stocks that are hedged with options may not be eligible for long-term capital gains tax treatment. If positions held by the Fund were treated as “straddles” for federal income tax purposes, or the Fund’s risk of loss with respect to a position was otherwise diminished as set forth in Treasury Regulations, dividends on stocks that are a part of such positions would not constitute qualified dividend income subject to such favorable income tax treatment and would not be eligible for the dividends received deduction for corporate shareholders. In addition, generally, straddles are subject to certain rules that may affect the amount, character and timing of the Fund’s gains and losses with respect to straddle positions. The Fund is not designed for investors seeking a tax efficient investment.

The net asset value of the Fund will fluctuate based on changes in the value of the U.S. equity securities held by the Fund.  Equity prices can fall rapidly in response to developments affecting a specific company or industry, or to changing economic, political or market conditions. Common stocks are generally exposed to greater risk than other types of securities, such as preferred stock and debt obligations, because common stockholders generally have inferior rights to receive payment from issuers.

○Authorized Participants, Market Makers, and Liquidity Providers Limitation Risk. The Fund has a limited number of financial institutions that may act as Authorized Participants (“APs”).

Prospectus [Line Items]  
Risk [Text Block]
○Cash Redemption Risk. The Fund’s investment strategy may require it to effect redemptions, in whole or in part, for cash. As a result, the Fund may be required to sell portfolio securities to obtain the cash needed to distribute redemption proceeds. This may cause the Fund to recognize investment income and/or capital gains or losses that it might not have recognized if it had completely satisfied the redemption in-kind. As a result, the Fund may be less tax efficient if it includes such a cash payment than if the in-kind redemption process was used exclusively. In addition, with cash redemptions, the Fund may incur brokerage costs and taxable gains losses it would not incur if utilizing a redemption in-kind. These costs could decrease the NAV if they are imposed on the Fund.

○Trading. Although Shares are listed for trading on a national securities exchange, the Nasdaq Stock Market LLC (the “Exchange”), and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that Shares will trade with any volume, or at all, on any stock exchange. In stressed market conditions, the liquidity of Shares may begin to mirror the liquidity of the Fund’s underlying portfolio holdings, which can be significantly less liquid than Shares.

 

NEOS Nasdaq-100(R) Hedged Equity Income ETF | Collared Options Strategy Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]
●Collared Options Strategy Risk. Writing and buying options are speculative activities and entail greater than ordinary investment risks. The Fund’s use of call and put options can lead to losses because of adverse movements in the price or value of the reference asset, which may be magnified by certain features of the options.

 

○Call options may limit the Fund’s upside capture in rising markets and put options may not protect the Fund from losses in declining markets.

 

○In a rising market, the upside capture may be limited by the strike price of the short call position. Conversely, the downside protection offered by the put may be limited due to the difference between the current market value of the reference asset and the strike price of the long put.

 

○When selling a call option, the Fund will receive a premium; however, this premium may not be enough to offset a loss incurred by the Fund if the price of the reference asset is above the strike price by an amount equal to or greater than the premium.

 

○If the model indicates a written call option should be closed prior to its expiration date (e.g., because the market price for the reference asset is above the strike price), and the value of the reference asset increases after the written call option is closed, the Fund may nevertheless underperform the reference asset.

 

○Options are rolled at the end of each month. If you purchase Fund shares on any day other than the roll date or hold shares for more or less than the roll period, the value of your investment in the Fund may not be protected against a decline in the value of the reference asset and may not benefit from a gain in the value of the reference asset.

 

○The value of an option may be adversely affected if the market for the option becomes less liquid, and will be affected by changes in the value or yield of the option’s reference asset, an increase in interest rates, a change in the actual or perceived volatility of the stock market or the reference asset and the remaining time to expiration. Additionally, the value of an option does not increase or decrease at the same rate as the reference asset. The price of an option reflects the time value of the option, which decreases over time as the option gets closer to its expiration date.

 

○As a seller (writer) of a put option, the Fund will tend to lose money if the value of the reference index or security falls below the strike price. As the buyer of a put option, the Fund risks losing the entire premium invested in the option if the Fund does not exercise the option.

 

The Fund’s use of options may reduce the Fund’s ability to profit from increases in the value of the Fund’s equity holdings. If the price of the reference asset of a written call option rises above its strike price, the value of the option and, consequently, the Fund may decline significantly more than if the Fund invested solely in the reference asset instead of using options. Similarly, if the price of the reference asset of a purchased put option remains above its strike price, the option may become worthless, and, consequently the value of the Fund may decline significantly more than if the Fund invested solely in the reference asset instead of using options.

 

NEOS Nasdaq-100(R) Hedged Equity Income ETF | Tracking Stock Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]
●Tracking Stock Risk. Tracking stock is a separate class of common stock designed to “track” the performance of a specific unit or operating division within a larger company. As a result, a tracking stock’s value may decline even if the common stock of the larger company increases in value. Tracking stocks share many of the same investing risks as common stocks, but the holders of tracking stock may not share the same rights as holders of a company’s common stock.

●Correlation Risk. The Fund expects to invest a portion of its assets to replicate the holdings of the Nasdaq-100®, and the Fund’s Adviser does not expect to sell shares of an equity security due to current or projected underperformance of a security, industry, or sector, unless that security is removed from the Nasdaq-100®. Although the Fund expects to invest a portion of its assets to replicate the holdings of the Nasdaq-100®, the performance of such portion of the Fund and the Nasdaq-100® may differ from each other for a variety of reasons. For example, the Fund incurs operating expenses and portfolio transaction costs not incurred by the Nasdaq-100®. In addition, the Fund may not be fully invested in the securities of the Nasdaq-100® at all times or may hold securities not included in the Nasdaq-100®

Risk [Text Block]
●Depositary Receipt Risk. American Depositary Receipts (“ADRs”) involve risks similar to those associated with investments in foreign securities and certain additional risks. ADRs listed on U.S. exchanges are issued by banks or trust companies, and entitle the holder to all dividends and capital gains that are paid out on the underlying foreign shares. When the Fund invests in ADRs as a substitute for a direct investment in the underlying foreign shares, the Fund is exposed to the risk that the ADRs may not provide a return that corresponds precisely with that of the underlying foreign shares.

 

NEOS Nasdaq-100(R) Hedged Equity Income ETF | Foreign Investment Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]
●Foreign Investment Risk. Because of the Fund’s investment in non-U.S. companies, changes in foreign economies and political climates are more likely to affect the Fund than a fund that invests exclusively in U.S. companies. There may be less government supervision of foreign markets, resulting in non-uniform accounting practices and less publicly available information. The value of foreign investments may be affected by changes in exchange control regulations, application of foreign tax laws (including withholding tax), changes in governmental administration or economic or monetary policy (in this country or abroad) or changed circumstances in dealings between nations.

●High Portfolio Turnover Risk. The Fund may frequently buy and sell portfolio securities and other assets to rebalance the Fund’s exposure to various market sectors. Higher portfolio turnover may result in the Fund paying higher levels of transaction costs and generating greater tax liabilities for shareholders. Portfolio turnover risk may cause the Fund’s performance to be less than you expect.

●Return of Capital Risk. The Fund expects to make monthly distributions regardless of its performance. All or a portion of such distributions may represent a return of capital. A return of capital is the portion of the distribution representing the return of your investment in the Fund. A return of capital is generally tax-free to the extent of a shareholder’s basis in the Fund’s shares and reduces the shareholder’s basis in their shares and results in a higher capital gain or lower capital loss when the shares on which the return of capital distribution was received are sold. After a shareholder’s basis in the shares has been reduced to zero, return of capital distributions will be treated as gain from the sale of the shareholder’s shares.

Prospectus [Line Items]  
Risk [Text Block]
●Non-Diversification Risk. Although the Fund intends to invest in a variety of securities and instruments, the Fund will be considered to be non-diversified, which means that it may invest more of its assets in the securities of a single issuer or a smaller number of issuers than if it were a diversified fund. As a result, the Fund may be more exposed to the risks associated with and developments affecting an individual issuer or a smaller number of issuers than a fund that invests more widely. This may increase the Fund’s volatility and cause the performance of a relatively smaller number of issuers to have a greater impact on the Fund’s performance. However, the Fund intends to satisfy the diversification requirements for qualifying as a regulated investment company (a “RIC”) under Subchapter M of the Internal Revenue Code of 1986, as amended (the “Code”).

Active Management Risk. The Fund is actively managed, which means that investment decisions are made based on investment views. There is no guarantee that the investment views will produce the desired results or expected returns, which may cause the Fund to fail to meet its investment objective or to underperform its benchmark index or funds with similar investment objectives and strategies. Furthermore, active trading that can accompany active management may result in high portfolio turnover, which may have a negative impact on performance. Active trading may result in higher brokerage costs or mark-up charges, which are ultimately passed on to shareholders of the Fund. Active trading may also result in adverse tax consequences.

Concentration Risk. Since the Fund will invest in up to 100% of the constituents of the Index, the Fund itself will be concentrated in certain real estate industries or sectors. The Fund may be susceptible to an increased risk of loss, including losses due to adverse events that affect the Fund’s investments more than the market as a whole, to the extent that the Fund’s investments are concentrated in the securities of a particular issuer or issuers, country, group of countries, region, market, industry, group of industries, sector or asset class.

Covered Call Option Writing Risk. By writing covered call options, in return for the receipt of premiums, the Fund will give up the opportunity to benefit from potential increases in the value of the Index above the exercise prices of such options, but will continue to bear the risk of declines in the value of the Index until the option expires or is closed out.

 

NEOS Real Estate High Income ETF | Derivatives Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Derivatives Risk. Options are a derivative investment. The use of derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities and other traditional investments. These risks include (i) the risk that the counterparty to a derivative transaction may not fulfil its contractual obligations; (ii) risk of mispricing or improper valuation; and (iii) the risk that changes in the value of the derivative may not correlate perfectly with the underlying asset, rate or index. Derivative prices are highly volatile and may fluctuate substantially during a short period of time. Such prices are influenced by numerous factors that affect the markets, including, but not limited to: changing supply and demand relationships; government programs and policies; national and international political and economic events, changes in interest rates, inflation and deflation and changes in supply and demand relationships.

Exchange Traded Funds (“ETFs”) Risk. The Fund is structured as an ETF. As a result, the Fund is subject to special risks, including:

 

NEOS Real Estate High Income ETF | Not Individually Redeemable [Member]  
Prospectus [Line Items]  
Risk [Text Block]
●Not Individually Redeemable. The Fund’s shares (“Shares”) are not redeemable by retail investors and may be redeemed only by Authorized Participants at net asset value (“NAV”) and only in Creation Units. A retail investor generally incurs brokerage costs when selling shares.

 

NEOS Real Estate High Income ETF | Trading Issues [Member]  
Prospectus [Line Items]  
Risk [Text Block]
●Trading Issues. Trading in Shares on the Exchange may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in Shares inadvisable, such as extraordinary market volatility. There can be no assurance that Shares will continue to meet the listing requirements of the Exchange which may result in the Shares being delisted. An active trading market for the Shares may not be developed or maintained. If the Shares are traded outside a collateralized settlement system, the number of financial institutions that can act as Authorized Participants that can post collateral on an agency basis is limited, which may limit the market for the Shares.

 

NEOS Real Estate High Income ETF | Market Price Variance Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]
●Market Price Variance Risk. The market prices of Shares will fluctuate in response to changes in NAV and supply and demand for Shares and will include a “bid-ask spread” charged by the exchange specialists, market makers or other participants that trade the Shares. There may be times when the market price and the NAV vary significantly. This means that Shares may trade at a discount to NAV.

 

○In times of market stress, market makers may step away from their role market making in the Shares and in executing trades, which can lead to differences between the market value of the Shares and the Fund’s NAV.

 

○The market price of the Shares may deviate from the Fund’s NAV, particularly during times of market stress, with the result that investors may pay significantly more or significantly less for the Shares than the Fund’s NAV, which is reflected in the bid and ask price for the Shares or in the closing price.

 

○In stressed market conditions, the market for the Shares may become less liquid in response to the deteriorating liquidity of the Fund’s portfolio. This adverse effect on the liquidity of the Shares may, in turn, lead to differences between the market value of the Shares and the Fund’s NAV.

 

NEOS Real Estate High Income ETF | Authorized Participant Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]
●Authorized Participant Risk. Only an Authorized Participant may engage in creation or redemption transactions directly with the Fund. The Fund has a limited number of institutions that may act as an Authorized Participant on an agency basis (i.e., on behalf of other market participants). To the extent that Authorized Participants exit the business or are unable to proceed with creation or redemption orders with respect to the Fund and no other Authorized Participant is able to step forward to create or redeem Creation Units, Fund shares may be more likely to trade at a premium or discount to net asset value and possibly face trading halts or delisting. Authorized Participant concentration risk may be heightened for securities or instruments that have lower trading volumes.

 

Additionally, purchases and redemptions of creation units primarily with cash rather than through in-kind delivery of portfolio securities may cause the Fund to incur certain costs, including brokerage costs or taxable gains or losses that it might not have incurred if it made a redemption in-kind, and therefore decrease the Fund's NAV to the extent not offset by a transaction fee payable by an AP.

Prospectus [Line Items]  
Risk [Text Block]

Issuer Risk. Changes in the financial condition or credit rating of an issuer or counterparty, changes in specific economic or political conditions that affect a particular type of security or issuer, and changes in general economic or political conditions can affect a security’s or instrument’s value. The values of securities of smaller, less well-known issuers can be more volatile than those of larger issuers. Issuer-specific events can have a negative impact on the value of the Fund.

 

NEOS Real Estate High Income ETF | Market and Geopolitical Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Market and Geopolitical Risk. The increasing interconnectivity between global economies and financial markets increases the likelihood that events or conditions in one region or financial market may adversely impact issuers in a different country, region or financial market. Securities in the Fund’s portfolio may underperform due to inflation (or expectations for inflation), interest rates, global demand for particular products or resources, natural disasters, climate change and climate-related events, pandemics, epidemics, terrorism, international conflicts, regulatory events and governmental or quasi-governmental actions. The occurrence of global events similar to those in recent years may result in market volatility and may have long term effects on financial markets worldwide.

 

NEOS Real Estate High Income ETF | Options Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Options Risk. Buying and selling (writing) options are speculative activities and entail greater than ordinary investment risks. Options enable the Fund to purchase exposure that is significantly greater than the premium paid. Consequently, the value of such options can be volatile, and a small investment in options can have a large impact on the performance of the Fund. The Fund risks losing all or part of the cash paid (premiums) for purchasing options. Even a small decline in the value of a reference asset underlying call options or a small increase in the value of a reference asset underlying put options can result in the entire investment in such options being lost. The Fund’s options also may fail to track the performance of their underlying reference asset, which may limit the effectiveness of the Fund’s strategy. The potential loss from written options can exceed the Fund’s initial investment in such options and could be unlimited

 

NEOS Real Estate High Income ETF | Sector Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Sector Risk. Sector risk is the possibility that securities within the same sectors will decline in price due to sector-specific market or economic developments. If the Fund invests more heavily in a particular sector, through the underlying constituents of the Index, the value of its shares may be especially sensitive to factors and economic risks that specifically affect that sector. As a result, the Fund’s share price may fluctuate more widely than the value of shares of a fund that invests in a broader range of sectors.

 

NEOS Real Estate High Income ETF | Tax Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Tax Risk. The Fund invests in derivatives. The federal income tax treatment of a derivative may not be as favorable as a direct investment in an underlying asset. Derivatives may produce taxable income and taxable realized gain. Derivatives may adversely affect the timing, character and amount of income the Fund realizes from its investments. As a result, a larger portion of the Fund’s distributions may be treated as ordinary income rather than as capital gains. In addition, certain derivatives are subject to mark-to-market or straddle provisions of the Internal Revenue Code of 1986, as amended (the “Internal Revenue Code”). If such provisions are applicable, there could be an increase (or decrease) in the amount of taxable dividends paid by the Fund.

 

NEOS Real Estate High Income ETF | Valuation Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Valuation Risk. The price the Fund could receive upon the sale of a security or other asset may differ from the Fund’s valuation of the security or other asset and from the value used by the Index, particularly for securities or other assets that trade in low volume or volatile markets or that are valued using a fair value methodology as a result of trade suspensions or for other reasons. In addition, the value of the securities or other assets in the Fund’s portfolio may change on days or during time periods when shareholders will not be able to purchase or sell the Fund’s shares. Authorized Participants who purchase or redeem Fund shares on days when the Fund is holding fair-valued securities may receive fewer or more shares, or lower or higher redemption proceeds, than they would have received had the Fund not fair-valued securities or used a different valuation methodology. The Fund’s ability to value investments may be impacted by technological issues or errors by pricing services or other third- party service providers.

 

 

NEOS Real Estate High Income ETF | Interest Rate Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Interest Rate Risk. Rising interest rates could result in higher costs of capital for real estate companies, which could negatively affect a real estate company’s ability to meet its payment obligations. On the other hand, declining interest rates could result in increased prepayment on loans and require redeployment of capital in less desirable investments by such real estate company. Thus, rising interest rates and/or declining interest rates may cause the value of the Fund’s investments to decline.

 

NEOS Real Estate High Income ETF | Cybersecurity Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Cybersecurity Risk. The computer systems, networks and devices used by the Funds and their service providers to carry out routine business operations employ a variety of protections designed to limit damage or interruption from computer viruses, network failures, computer and telecommunication failures, infiltration by unauthorized persons and security breaches. Despite the various protections utilized by the Funds and their service providers, systems, networks, or devices potentially can be breached. Each Fund and its shareholders could be negatively impacted as a result of a cybersecurity breach.

 

Cybersecurity breaches can include unauthorized access to systems, networks, or devices; infection from computer viruses or other malicious software code; and attacks that shut down, disable, slow, or otherwise disrupt operations, business processes, or website access or functionality. Cybersecurity breaches may cause disruptions and impact each Fund’s business operations, potentially resulting in financial losses; interference with each Fund’s ability to calculate its NAV; impediments to trading; the inability of each Fund, the adviser, and other service providers to transact business; violations of applicable privacy and other laws; regulatory fines, penalties, reputational damage, reimbursement or other compensation costs, or additional compliance costs; as well as the inadvertent release of confidential information.

 

Similar adverse consequences could result from cybersecurity breaches affecting issuers of securities in which the Funds invest; counterparties with which the Funds engage in transactions; governmental and other regulatory authorities; exchange and other financial market operators, banks, brokers, dealers, insurance companies, and other financial institutions (including financial intermediaries and service providers for a Fund’s shareholders); and other parties. In addition, substantial costs may be incurred by these entities in order to limit any cybersecurity breaches in the future.

 

NEOS Real Estate High Income ETF | FLEX Options Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

FLEX Options Risk. Trading FLEX Options involves risks different from, or possibly greater than, the risks associated with investing directly in securities. The Fund may experience losses from specific FLEX Option positions and certain FLEX Option positions may expire worthless. The FLEX Options are listed and trade on an exchange; however, no one can guarantee that a liquid secondary trading market will exist for the FLEX Options. In the event that trading in the FLEX Options is limited or absent, the value of the Fund’s FLEX Options may decrease. In a less liquid market for the FLEX Options, liquidating the FLEX Options may require the payment of a premium (for written FLEX Options) or acceptance of a discounted price (for purchased FLEX Options) and may take longer to complete. A less liquid trading market may adversely impact the value of the FLEX Options and Fund shares and result in the Fund being unable to achieve its investment objective. Less liquidity in the trading of the Fund’s FLEX Options could have an impact on the prices paid or received by the Fund for the FLEX Options in connection with creations and redemptions of the Fund’s shares. Depending on the nature of this impact to pricing, the Fund may be forced to pay more for redemptions (or receive less for creations) than the price at which it currently values the FLEX Options. Such overpayment or under collection could reduce the Fund’s ability to achieve its investment objective. Additionally, in a less liquid market for the FLEX Options, the liquidation of a large number of options may more significantly impact the price. A less liquid trading market may adversely impact the value of the FLEX Options and the value of your investment. The trading in FLEX Options may be less deep and liquid than the market for certain other exchange-traded options, non-customized options or other securities.

 

NEOS Real Estate High Income ETF | Leverage Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Leverage Risk. Real estate companies may use leverage (and some may be highly leveraged). Leverage, and the financial covenants related thereto, may increase investment risk and the risks normally associated with debt financing and adversely affect a company’s operations and market value, especially during periods of rising interest rates.

 

NEOS Real Estate High Income ETF | Liquidity Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Liquidity Risk. Investing in real estate companies may involve risks similar to those associated with investing in small-capitalization companies. Lower trading volume in a real estate company shares means that buy and sell transactions in those shares could have a magnified impact on share price. In addition, real estate is relatively illiquid and, therefore, a real estate company may have a limited ability to vary or liquidate its investments at opportune times.

 

NEOS Real Estate High Income ETF | Equity Securities Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Equity Securities Risk. The net asset value of the Fund will fluctuate based on changes in the value of the U.S. equity securities, including REITs, held by the Fund. The value of a security may decline for a number of reasons that may directly relate to the issuer as well as due to general industry or market conditions. Common stock is subordinated to preferred securities and debt in a company’s capital structure. Common stock has the lowest priority, and the greatest risk, with respect to dividends and any liquidation payments in the event of an issuer’s bankruptcy. Equity prices can fall rapidly in response to developments affecting a specific company or industry, or to changing economic, political or market conditions.

 

NEOS Real Estate High Income ETF | Management Risk [Member]

Management Risk. As the Fund will not fully replicate the Index due to its options strategy, it is subject to the risk that the Adviser’s investment strategy may not produce the intended results or achieve the Fund’s objective.

 

NEOS Real Estate High Income ETF | REIT Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

REIT Risk. The value of investments in REIT shares may decline because of adverse developments affecting the real estate industry and real property values. In general, real estate values can be affected by a variety of factors, including supply and demand for properties, the economic health of the country or of different regions, and the strength of specific industries that rent properties. Also, qualification as a REIT under the Internal Revenue Code of 1986, as amended (the “Code”) in any particular year is a complex analysis that depends on a number of factors. There can be no assurance that an entity in which the Fund invests with the expectation that it will be taxed as a REIT will, in fact, qualify as a REIT. An entity that fails to qualify as a REIT would be subject to a corporate level tax, would not be entitled to a deduction for dividends paid to its shareholders and would not pass through to its shareholders the character of income earned by the entity.

 

NEOS Real Estate High Income ETF | Real Estate Investment Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Real Estate Investment Risk. The Fund concentrates its investments in real estate companies such as REITs. As such, the Fund is subject to risks associated with the direct ownership of real estate securities and an investment in the Fund will be closely linked to the performance of the real estate markets. These risks include, among others: declines in the value of real estate; risks related to general and local economic conditions; possible lack of availability of mortgage funds or other limits to accessing the credit or capital markets; defaults by borrowers or tenants, particularly during an economic downturn; and changes in interest rates. Real estate is highly sensitive to general and local economic conditions and developments and is characterized by intense competition and periodic overbuilding. Many real estate companies, including REITs, utilize leverage (and some may be highly leveraged), which increases investment risk and the risk normally associated with debt financing, and could potentially magnify the Fund’s losses.

Risk [Text Block]

Equity REITs Risk. Certain REITs may make direct investments in real estate, often referred to as “Equity REITs.” Equity REITs earn rental income from leasing those properties and may realize gains or losses when selling the properties. Equity REITs will be affected by conditions in the real estate rental market.

 

NEOS Real Estate High Income ETF | Operational Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Operational Risk. Real estate companies are dependent upon management skills and may have limited financial resources. Real estate companies are generally not diversified and may be subject to heavy cash flow dependency, default by borrowers and self-liquidation. A real estate company may also have joint ventures in certain of its properties and, consequently, its ability to control decisions relating to such properties may be limited.

 

NEOS Real Estate High Income ETF | Property Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Property Risk. Real estate companies may be subject to risks relating to functional obsolescence or reduced desirability of properties; extended vacancies due to economic conditions and tenant bankruptcies; catastrophic events such as earthquakes, hurricanes, tornadoes and terrorist acts; casualty or condemnation losses; and demographic trends, such as population shifts, changing tastes and values, and other legal, cultural, technological, global or local economic developments.

NEOS Real Estate High Income ETF | Repayment Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Repayment Risk. The prices of real estate company securities may drop because of the failure of borrowers to repay their loans, poor management, or the inability to obtain financing either on favorable terms or at all. If the properties do not generate sufficient income to meet operating expenses, the income and ability of the real estate companies to make payments of interest and principal on their loans will be adversely affected.

 

NEOS Real Estate High Income ETF | U.S. Tax Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

U.S. Tax Risk. Certain U.S. real estate companies, such as REITs, are subject to special U.S. federal tax requirements. A REIT that fails to comply with such tax requirements may be subject to U.S. federal income taxation, which may affect the value of the REIT and the characterization of the REIT's distributions. The U.S. federal tax requirement that a REIT distributes substantially all of its net income to its shareholders may result in the REIT having insufficient capital for future expenditures.

 

NEOS Real Estate High Income ETF | Index Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Index Risk. The Fund will not sell an equity holding due to current or projected underperformance of the holding, industry or sector unless that holding is removed from the Index or selling the holding is otherwise required upon rebalancing of the Index. Market disruptions and regulatory restrictions could have an adverse effect on the Fund’s ability to adjust its equity exposure to the required levels in order to track the Index . Errors in index data, index computations or the construction of the Index in accordance with its methodology may occur from time to time and may not be identified and corrected by the underlying index provider for a period of time or at all, which may have an adverse impact on the Fund and its shareholders. Unusual market conditions or other unforeseen circumstances (such as natural disasters, political unrest or war) may impact the underlying index provider or a third-party data provider, and could cause the underlying index provider to postpone a scheduled rebalance. This could cause the Index to vary from its normal or expected composition.

 

The Fund’s equity holdings may be subject to “tracking error,” which is the divergence of the performance of the equity holdings from that of the Index. Tracking error may occur because of differences between the securities and other instruments held in the Fund’s portfolio and those included in the Index , pricing differences, transaction costs incurred by the Fund, the Fund’s holding of uninvested cash, differences in timing of the accrual or the valuation of dividends or interest received by the Fund or distributions paid to the Fund’s shareholders, the requirements to maintain pass-through tax treatment, portfolio transactions carried out to minimize the distribution of capital gains to shareholders, acceptance of custom baskets, changes to the Index or the costs to the Fund of complying with various new or existing regulatory requirements, among other reasons. This risk may be heightened during times of increased market volatility or other unusual market conditions. Tracking error also may result because the securities within the same group of industries will decline in price due to sector-specific market or economic developments. If the Fund invests more heavily in a particular sector, the value of its shares may be especially sensitive to factors and economic risks that specifically affect that sector. As a result, the Fund’s share price may fluctuate more widely than the value of shares of a fund that invests in a broader range of industries.

Active Management Risk. The Fund is actively managed, which means that investment decisions are made based on investment views. There is no guarantee that the investment views will produce the desired results or expected returns, which may cause the Fund to fail to meet its investment objective or to underperform its benchmark index or funds with similar investment objectives and strategies. Furthermore, active trading that can accompany active management may result in high portfolio turnover, which may have a negative impact on performance. Active trading may result in higher brokerage costs or mark-up charges, which are ultimately passed on to shareholders of the Fund. Active trading may also result in adverse tax consequences.

The Fund may be susceptible to an increased risk of loss, including losses due to adverse events that affect the Fund’s investments more than the market as a whole, to the extent that the Fund’s investments are concentrated in the securities of a particular issuer or issuers, country, group of countries, region, market, industry, group of industries, sector or asset class.

Risk [Text Block]

Tax Risk. The Fund invests in derivatives. The federal income tax treatment of a derivative may not be as favorable as a direct investment in an underlying asset. Derivatives may produce taxable income and taxable realized gain. Derivatives may adversely affect the timing, character and amount of income the Fund realizes from its investments. As a result, a larger portion of the Fund’s distributions may be treated as ordinary income rather than as capital gains. In addition, certain derivatives are subject to mark-to-market or straddle provisions of the Internal Revenue Code of 1986, as amended (the “Internal Revenue Code”). If such provisions are applicable, there could be an increase (or decrease) in the amount of taxable dividends paid by the Fund.

 

 

NEOS Russell 2000 High Income ETF | Valuation Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Valuation Risk. The price the Fund could receive upon the sale of a security or other asset may differ from the Fund’s valuation of the security or other asset and from the value used by the Reference Index, particularly for securities or other assets that trade in low volume or volatile markets or that are valued using a fair value methodology as a result of trade suspensions or for other reasons. In addition, the value of the securities or other assets in the Fund’s portfolio may change on days or during time periods when shareholders will not be able to purchase or sell the Fund’s shares. Authorized Participants who purchase or redeem Fund shares on days when the Fund is holding fair-valued securities may receive fewer or more shares, or lower or higher redemption proceeds, than they would have received had the Fund not fair-valued securities or used a different valuation methodology. The Fund’s ability to value investments may be impacted by technological issues or errors by pricing services or other third- party service providers.

 

NEOS Russell 2000 High Income ETF | Cybersecurity Risk [Member]

Risk [Text Block]

Cybersecurity Risk. The computer systems, networks and devices used by the Funds and their service providers to carry out routine business operations employ a variety of protections designed to limit damage or interruption from computer viruses, network failures, computer and telecommunication failures, infiltration by unauthorized persons and security breaches. Despite the various protections utilized by the Funds and their service providers, systems, networks, or devices potentially can be breached. Each Fund and its shareholders could be negatively impacted as a result of a cybersecurity breach.

 

Cybersecurity breaches can include unauthorized access to systems, networks, or devices; infection from computer viruses or other malicious software code; and attacks that shut down, disable, slow, or otherwise disrupt operations, business processes, or website access or functionality. Cybersecurity breaches may cause disruptions and impact each Fund’s business operations, potentially resulting in financial losses; interference with each Fund’s ability to calculate its NAV; impediments to trading; the inability of each Fund, the adviser, and other service providers to transact business; violations of applicable privacy and other laws; regulatory fines, penalties, reputational damage, reimbursement or other compensation costs, or additional compliance costs; as well as the inadvertent release of confidential information.

 

Similar adverse consequences could result from cybersecurity breaches affecting issuers of securities in which the Funds invest; counterparties with which the Funds engage in transactions; governmental and other regulatory authorities; exchange and other financial market operators, banks, brokers, dealers, insurance companies, and other financial institutions (including financial intermediaries and service providers for a Fund’s shareholders); and other parties. In addition, substantial costs may be incurred by these entities in order to limit any cybersecurity breaches in the future.

Small-Capitalization Companies Risk. Stock prices of small-capitalization companies may be more volatile than those of larger companies and, therefore, the Fund’s share price may be more volatile than those of funds that invest a larger percentage of their assets in stocks issued by mid- or large-capitalization companies.

Reference Index ETF Risk. The Fund may invest in the securities of other investment companies including the Russell 2000 Underlying ETFs. If the Fund invests in and, thus, is a shareholder of, another investment company, the Fund’s shareholders will indirectly bear the Fund’s proportionate share of the fees and expenses paid by such other investment company, including advisory fees, in addition to both the management fees payable directly by the Fund to the Fund’s own investment adviser and the other expenses that the Fund bears directly in connection with the Fund’s own operations. Each of the underlying index ETFs also are subject to the following risks.

Index-Related Risk. There is no guarantee that the Russell 2000 Underlying ETFs that the Fund invests in will have investment results with a high degree of correlation to those of the Russell 2000® or that the Fund will achieve its investment objective. Market disruptions and regulatory restrictions could have an adverse effect on an Russell 2000 Underlying ETF’s ability to adjust its exposure to the required levels in order to track the Russell 2000®. Errors in index data, index computations or the construction of the Russell 2000® in accordance with its methodology may occur from time to time and may not be identified and corrected by the underlying index provider for a period of time or at all, which may have an adverse impact on the Fund and its shareholders. Unusual market conditions or other unforeseen circumstances (such as natural disasters, political unrest or war) may impact the underlying index provider or a third-party data provider, and could cause the underlying index provider to postpone a scheduled rebalance. This could cause the Russell 2000® to vary from its normal or expected composition.

Risk [Text Block]

Tracking Error Risk. The Russell 2000 Underlying ETFs in which the Fund invests may be subject to “tracking error,” which is the divergence of a Russell 2000 Underlying ETF’s performance from that of the Russell 2000®. Tracking error may occur because of differences between the securities and other instruments held in the Russell 2000 Underlying ETF’s portfolio and those included in the Russell 2000®, pricing differences, transaction costs incurred by the Russell 2000 Underlying ETFETF, the Russell 2000 Underlying ETF’s holding of uninvested cash, differences in timing of the accrual or the valuation of dividends or interest received by the Russell 2000 Underlying ETF or distributions paid to the Russell 2000 Underlying ETF’s shareholders, the requirements to maintain pass-through tax treatment, portfolio transactions carried out to minimize the distribution of capital gains to shareholders, acceptance of custom baskets, changes to the Russell 2000® or the costs to the Russell 2000 Underlying ETF of complying with various new or existing regulatory requirements, among other reasons. This risk may be heightened during times of increased market volatility or other unusual market conditions. Tracking error also may result because the securities within the same group of industries will decline in price due to sector-specific market or economic developments. If the Fund invests more heavily in a particular sector, the value of its shares may be especially sensitive to factors and economic risks that specifically affect that sector. As a result, the Fund’s share price may fluctuate more widely than the value of shares of a fund that invests in a broader range of industries.

●Concentration Risk. The Fund may focus its investments in securities of a particular industry or group of industries to the extent that the Reference Index focuses its investments in securities of a particular industry or group of industries. Economic, legislative or regulatory developments may occur that significantly affect the industry or group of industries. This may cause the Fund’s share price to fluctuate more than that of a fund that does not focus in a particular industry or group of industries.

●Derivatives Risk. The Fund invests in options that derive their performance from the performance of an underlying reference asset. Derivatives, such as the options in which the Fund invests, can be volatile and involve various types and degrees of risks, depending upon the characteristics of a particular derivative. Derivatives may have investment exposures that are greater than their cost would suggest, meaning that a small investment in a derivative could have a substantial impact on the performance of the Fund. The Fund could experience a loss if its derivatives do not perform as anticipated, the derivatives are not correlated with the performance of their reference asset, or if the Fund is unable to purchase or liquidate a position because of an illiquid secondary market. The market for many derivatives is, or suddenly can become, illiquid. Changes in liquidity may result in significant, rapid, and unpredictable changes in the prices for derivatives.

●Market and Geopolitical Risk. The increasing interconnectivity between global economies and financial markets increases the likelihood that events or conditions in one region or financial market may adversely impact issuers in a different country, region or financial market. Securities in the Fund’s portfolio may underperform due to inflation (or expectations for inflation), interest rates, global demand for particular products or resources, natural disasters, climate change and climate-related events, pandemics, epidemics, terrorism, international conflicts, regulatory events and governmental or quasi-governmental actions.

○Information Technology Sector Risk. Market or economic factors impacting information technology companies and companies that rely heavily on technological advances could have a significant effect on the value of the Fund’s investments. The value of stocks of information technology companies and companies that rely heavily on technology is particularly vulnerable to rapid changes in technology product cycles, rapid product obsolescence, government regulation and competition, both domestically and internationally, including competition from foreign competitors with lower production costs. Information technology companies are heavily dependent on patent and intellectual property rights, the loss or impairment of which may adversely affect profitability.

 

NEOS S&P 500(R) Hedged Equity Income ETF | Tax Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]
●Tax Risk. The Fund expects to generate premiums from its sale of call options. These options are expected to result in capital gains or losses for federal income tax purposes and may be subject to mark-to-market rules. These gains or losses will be wholly or partly long-term or short-term depending on the nature of the options sold by the Fund and will take into account premiums generated. In addition, stocks that are hedged with options may not be eligible for long-term capital gains tax treatment. If positions held by the Fund were treated as “straddles” for federal income tax purposes, or the Fund’s risk of loss with respect to a position was otherwise diminished as set forth in Treasury Regulations, dividends on stocks that are a part of such positions would not constitute qualified dividend income subject to such favorable income tax treatment and would not be eligible for the dividends received deduction for corporate shareholders. In addition, generally, straddles are subject to certain rules that may affect the amount, character and timing of the Fund’s gains and losses with respect to straddle positions. The Fund is not designed for investors seeking a tax efficient investment.

NEOS S&P 500(R) Hedged Equity Income ETF | Authorized Participants, Market Makers, and Liquidity Providers Limitation Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]
○Authorized Participants, Market Makers, and Liquidity Providers Limitation Risk. The Fund has a limited number of financial institutions that may act as Authorized Participants (“APs”). In addition, there may be a limited number of market makers and/or liquidity providers in the marketplace. To the extent either of the following events occur, Shares may trade at a material discount to NAV and possibly face delisting: (i) APs exit the business or otherwise become unable to process creation and/or redemption orders and no other APs step forward to perform these services, or (ii) market makers and/or liquidity providers exit the business or significantly reduce their business activities and no other entities step forward to perform their functions.

 

NEOS S&P 500(R) Hedged Equity Income ETF | Cash Redemption Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]
○Cash Redemption Risk. The Fund’s investment strategy may require it to effect redemptions, in whole or in part, for cash. As a result, the Fund may be required to sell portfolio securities to obtain the cash needed to distribute redemption proceeds. This may cause the Fund to recognize investment income and/or capital gains or losses that it might not have recognized if it had completely satisfied the redemption in-kind. As a result, the Fund may be less tax efficient if it includes such a cash payment than if the in-kind redemption process was used exclusively. In addition, with cash redemptions, the Fund may incur brokerage costs and taxable gains losses it would not incur if utilizing a redemption in-kind. These costs could decrease the NAV if they are imposed on the Fund.

Risk [Text Block]
○Shares May Trade at Prices Other Than NAV. As with all ETFs, Shares may be bought and sold in the secondary market at market prices. Although it is expected that the market price of Shares will approximate the Fund’s NAV, there may be times when the market price of Shares is more than the NAV intra-day (premium) or less than the NAV intra-day (discount) due to supply and demand of Shares or during periods of market volatility. This risk is heightened in times of market volatility, periods of steep market declines, and periods when there is limited trading activity for Shares in the secondary market, in which case such premiums or discounts may be significant.

○Trading. Although Shares are listed for trading on a national securities exchange, the Cboe BZX Exchange, Inc. (the “Exchange”), and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that Shares will trade with any volume, or at all, on any stock exchange. In stressed market conditions, the liquidity of Shares may begin to mirror the liquidity of the Fund’s underlying portfolio holdings, which can be significantly less liquid than Shares.

 

NEOS S&P 500(R) Hedged Equity Income ETF | Collared Options Strategy Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]
●Collared Options Strategy Risk. Writing and buying options are speculative activities and entail greater than ordinary investment risks. The Fund’s use of call and put options can lead to losses because of adverse movements in the price or value of the reference asset, which may be magnified by certain features of the options.

 

○Call options may limit the Fund’s upside capture in rising markets and put options may not protect the Fund from losses in declining markets.

 

○In a rising market, the upside capture may be limited by the strike price of the short call position. Conversely, the downside protection offered by the put may be limited due to the difference between the current market value of the reference asset and the strike price of the long put.

 

○When selling a call option, the Fund will receive a premium; however, this premium may not be enough to offset a loss incurred by the Fund if the price of the reference asset is above the strike price by an amount equal to or greater than the premium.

 

○If the model indicates a written call option should be closed prior to its expiration date (e.g., because the market price for the reference asset is above the strike price), and the value of the reference asset increases after the written call option is closed, the Fund may nevertheless underperform the reference asset.

 

○Options are rolled at the end of each month. If you purchase Fund shares on any day other than the roll date or hold shares for more or less than the roll period, the value of your investment in the Fund may not be protected against a decline in the value of the reference asset and may not benefit from a gain in the value of the reference asset.

 

○The value of an option may be adversely affected if the market for the option becomes less liquid, and will be affected by changes in the value or yield of the option’s reference asset, an increase in interest rates, a change in the actual or perceived volatility of the stock market or the reference asset and the remaining time to expiration. Additionally, the value of an option does not increase or decrease at the same rate as the reference asset. The price of an option reflects the time value of the option, which decreases over time as the option gets closer to its expiration date.

 

○As a seller (writer) of a put option, the Fund will tend to lose money if the value of the reference index or security falls below the strike price. As the buyer of a put option, the Fund risks losing the entire premium invested in the option if the Fund does not exercise the option.

 

The Fund’s use of options may reduce the Fund’s ability to profit from increases in the value of the Fund’s equity holdings. If the price of the reference asset of a written call option rises above its strike price, the value of the option and, consequently, the Fund may decline significantly more than if the Fund invested solely in the reference asset instead of using options. Similarly, if the price of the reference asset of a purchased put option remains above its strike price, the option may become worthless, and, consequently the value of the Fund may decline significantly more than if the Fund invested solely in the reference asset instead of using options.

 

NEOS S&P 500(R) Hedged Equity Income ETF | Correlation Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]
●Correlation Risk. The Fund expects to invest a portion of its assets to replicate the holdings of the S&P 500®, and the Adviser does not expect to sell shares of an equity security due to current or projected underperformance of a security, industry, or sector, unless that security is removed from the S&P 500®. Although the Fund expects to invest a portion of its assets to replicate the holdings of the S&P 500®, the performance of such portion of the Fund and the S&P 500® may differ from each other for a variety of reasons. For example, the Fund incurs operating expenses and portfolio transaction costs not incurred by the S&P 500®. In addition, the Fund may not be fully invested in the securities of the S&P 500® at all times or may hold securities not included in the S&P 500®.

 

NEOS S&P 500(R) Hedged Equity Income ETF | High Portfolio Turnover Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]
●High Portfolio Turnover Risk. The Fund may frequently buy and sell portfolio securities and other assets to rebalance the Fund’s exposure to various market sectors. Higher portfolio turnover may result in the Fund paying higher levels of transaction costs and generating greater tax liabilities for shareholders. Portfolio turnover risk may cause the Fund’s performance to be less than you expect.

○Large-Capitalization Investing. The securities of large-capitalization companies may be relatively mature compared to smaller companies and therefore subject to slower growth during times of economic expansion.

●Model and Data Risk. The Adviser will make use of quantitative models and information and data supplied by third parties to, among other things, help determine the strike prices of, or when to close, the Fund’s written put positions. To the extent the models used by the Adviser or the information and data supplied by third parties are incorrect or incomplete, the decisions made by the Adviser in reliance thereon will expose the Fund to potential risks and could lead to the Fund incurring losses or missing gains on its investments.

●Equity Market Risk. The equity securities held in the Fund’s portfolio may experience sudden, unpredictable drops in value or long periods of decline in value. This may occur because of factors that affect securities markets generally or factors affecting specific issuers, industries, or sectors in which the Fund invests. Common stocks are generally exposed to greater risk than other types of securities, such as preferred stock and debt obligations, because common stockholders generally have inferior rights to receive payment from issuers.

●New Fund Risk. The Fund is a new fund, with limited operating history, which may result in additional risks for investors in the Fund. There can be no assurance that the Fund will grow to or maintain an economically viable size, in which case the Board of Trustees may determine to liquidate the Fund. While shareholder interests will be the paramount consideration, the timing of any liquidation may not be favorable to certain individual shareholders.

Risk [Text Block]

Active Management Risk. The Fund is actively managed, which means that investment decisions are made based on investment views. There is no guarantee that the investment views will produce the desired results or expected returns, which may cause the Fund to fail to meet its investment objective or to underperform its benchmark index or funds with similar investment objectives and strategies. Furthermore, active trading that can accompany active management may result in high portfolio turnover, which may have a negative impact on performance. Active trading may result in higher brokerage costs or mark-up charges, which are ultimately passed on to shareholders of the Fund. Active trading may also result in adverse tax consequences.

 

NEOS Gold High Income ETF | Concentration Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Concentration Risk. Because the Fund invests more than 25% of its assets in the gold bullion industry, the Fund’s net asset value may fluctuate more than that of a fund that does not concentrate in the gold bullion industry.

 

NEOS Gold High Income ETF | Derivatives Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Derivatives Risk. Options are derivative investments. The use of derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities and other traditional investments. These risks include (i) the risk that the counterparty to a derivative transaction may not fulfil its contractual obligations; (ii) risk of mispricing or improper valuation; and (iii) the risk that changes in the value of the derivative may not correlate perfectly with the underlying asset, rate or index. Derivative prices are highly volatile and may fluctuate substantially during a short period of time. Such prices are influenced by numerous factors that affect the markets, including, but not limited to: changing supply and demand relationships; government programs and policies; national and international political and economic events, changes in interest rates, inflation and deflation and changes in supply and demand relationships. Trading derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities.

 

NEOS Gold High Income ETF | Exchange Traded Funds (“ETFs”) Risk [Member]  
Prospectus [Line Items]

Exchange Traded Funds (“ETFs”) Risk. The Fund is structured as an ETF. As a result, the Fund is subject to special risks, including:

 

NEOS Gold High Income ETF | Not Individually Redeemable [Member]  
Prospectus [Line Items]  
Risk [Text Block]
●Not Individually Redeemable. The Fund’s shares (“Shares”) are not redeemable by retail investors and may be redeemed only by Authorized Participants at net asset value (“NAV”) and only in Creation Units. A retail investor generally incurs brokerage costs when selling shares.

 

NEOS Gold High Income ETF | Trading Issues [Member]  
Prospectus [Line Items]  
Risk [Text Block]
●Trading Issues. Trading in Shares on Cboe BZX Exchange, Inc. (the “Exchange”) may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in Shares inadvisable, such as extraordinary market volatility. There can be no assurance that Shares will continue to meet the listing requirements of the Exchange which may result in the Shares being delisted. An active trading market for the Shares may not be developed or maintained. If the Shares are traded outside a collateralized settlement system, the number of financial institutions that can act as Authorized Participants that can post collateral on an agency basis is limited, which may limit the market for the Shares.

 

NEOS Gold High Income ETF | Market Price Variance Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]
●Market Price Variance Risk. The market prices of Shares will fluctuate in response to changes in NAV and supply and demand for Shares and will include a “bid-ask spread” charged by the exchange specialists, market makers or other participants that trade the Shares. There may be times when the market price and the NAV vary significantly. This means that Shares may trade at a discount to NAV.

 

○In times of market stress, market makers may step away from their role market making in the Shares and in executing trades, which can lead to differences between the market value of the Shares and the Fund’s NAV.

 

○The market price of the Shares may deviate from the Fund’s NAV, particularly during times of market stress, with the result that investors may pay significantly more or significantly less for the Shares than the Fund’s NAV, which is reflected in the bid and ask price for the Shares or in the closing price.

 

○In stressed market conditions, the market for the Shares may become less liquid in response to the deteriorating liquidity of the Fund’s portfolio. This adverse effect on the liquidity of the Shares may, in turn, lead to differences between the market value of the Shares and the Fund’s NAV.

 

NEOS Gold High Income ETF | Authorized Participant Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]
●Authorized Participant Risk. Only an Authorized Participant may engage in creation or redemption transactions directly with the Fund. The Fund has a limited number of institutions that may act as an Authorized Participant on an agency basis (i.e., on behalf of other market participants). To the extent that Authorized Participants exit the business or are unable to proceed with creation or redemption orders with respect to the Fund and no other Authorized Participant is able to step forward to create or redeem Creation Units, Fund shares may be more likely to trade at a premium or discount to net asset value and possibly face trading halts or delisting. Authorized Participant concentration risk may be heightened for securities or instruments that have lower trading volumes.

 

Additionally, purchases and redemptions of creation units primarily with cash rather than through in-kind delivery of portfolio securities may cause the Fund to incur certain costs, including brokerage costs or taxable gains or losses that it might not have incurred if it made a redemption in-kind, and therefore decrease the Fund’s NAV to the extent not offset by a transaction fee payable by an AP.

 

NEOS Gold High Income ETF | Market and Geopolitical Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Market and Geopolitical Risk. The increasing interconnectivity between global economies and financial markets increases the likelihood that events or conditions in one region or financial market may adversely impact issuers in a different country, region or financial market. Securities in the Fund’s portfolio may underperform due to inflation (or expectations for inflation), interest rates, global demand for particular products or resources, natural disasters, climate change and climate-related events, pandemics, epidemics, terrorism, international conflicts, regulatory events and governmental or quasi-governmental actions. The occurrence of global events similar to those in recent years may result in market volatility and may have long term effects on financial markets worldwide.

 

NEOS Gold High Income ETF | Options Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Options Risk. There are risks associated with the sale and purchase of options on Gold ETPs. Options enable the Fund to purchase exposure that is significantly greater than the premium paid. Consequently, the value of such options can be volatile, and a small investment in options can have a large impact on the performance of the Fund. The Fund risks losing all or part of the cash paid (premiums) for purchasing options. Even a small decline in the value of a reference asset underlying call options or a small increase in the value of a reference asset underlying put options can result in the entire investment in such options being lost. The Fund’s options also may fail to track the performance of their underlying reference asset, which may limit the effectiveness of the Fund’s strategy. The potential loss from written options can exceed the Fund’s initial investment in such options and could be unlimited.

 

NEOS Gold High Income ETF | Tax Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Tax Risk. The Fund invests in derivatives. The federal income tax treatment of a derivative may not be as favorable as a direct investment in an underlying asset. Derivatives may produce taxable income and taxable realized gain. Derivatives may adversely affect the timing, character and amount of income the Fund realizes from its investments. As a result, a larger portion of the Fund’s distributions may be treated as ordinary income rather than as capital gains. In addition, certain derivatives are subject to mark-to-market or straddle provisions of the Internal Revenue Code. If such provisions are applicable, there could be an increase (or decrease) in the amount of taxable dividends paid by the Fund. The use of derivatives, such as call options, may cause the Fund to realize higher amounts of short-term capital gains or otherwise affect the Fund’s ability to pay out dividends subject to preferential rates or the dividend deduction, thereby increasing the amount of taxes payable by some shareholders. The writing of call options by the Fund may significantly reduce or eliminate the ability to make distributions eligible to be treated as qualified dividend income or as eligible for the dividends received deduction for corporate shareholders.

 

To qualify as a regulated investment company (“RIC”), the Fund must meet certain requirements concerning the source of its income. The Fund’s investment in the Subsidiary is intended to provide exposure to gold in a manner that is consistent with the “qualifying income” requirement applicable to RICs. The Internal Revenue Service (“IRS”) has ceased issuing private letter rulings regarding whether the use of subsidiaries by investment companies to invest in certain instruments constitutes qualifying income. If the IRS determines that this source of income is not “qualifying income,” the Fund may cease to qualify as a RIC because the Fund has not received a private letter ruling and is not able to rely on private letter rulings issued to other taxpayers. Failure to qualify as a RIC could subject the Fund to adverse tax consequences, including a federal income tax on its net income at regular corporate rates, as well as a tax to shareholders on such income when distributed as an ordinary dividend.

 

Based on the principles underlying private letter rulings previously issued to other taxpayers, the Fund intends to treat its income from the Subsidiary as qualifying income without any such ruling from the IRS. The tax treatment of the Fund’s investment in the Subsidiary may be adversely affected by future legislation, court decisions, Treasury Regulations and/or guidance issued by the IRS that could affect whether income derived from such investments is “qualifying income” under Subchapter M of the Internal Revenue Code, or otherwise affect the character, timing and/or amount of the Fund’s taxable income or any gains or distributions made by the Fund.

 

NEOS Gold High Income ETF | Valuation Risk [Member]

Valuation Risk. The price the Fund could receive upon the sale of a security or other asset may differ from the Fund’s valuation of the security or other asset, particularly for securities or other assets that trade in low volume or volatile markets or that are valued using a fair value methodology. In addition, the value of the securities or other assets in the Fund’s portfolio may change on days or during time periods when shareholders will not be able to purchase or sell the Fund’s shares. Authorized Participants who purchase or redeem Fund shares on days when the Fund is holding fair-valued securities may receive fewer or more shares, or lower or higher redemption proceeds, than they would have received had the Fund not fair-valued securities or used a different valuation methodology. The Fund’s ability to value investments may be impacted by technological issues or errors by pricing services or other third- party service providers.

U.S. Government Securities Risk. U.S. Treasury obligations are backed by the “full faith and credit” of the U.S. government and generally have negligible credit risk. Securities issued or guaranteed by federal agencies or authorities and U.S. government-sponsored instrumentalities or enterprises may or may not be backed by the full faith and credit of the U.S. government.

 

NEOS Gold High Income ETF | FLEX Options Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

FLEX Options Risk. Trading FLEX Options involves risks different from, or possibly greater than, the risks associated with investing directly in securities. The Fund may experience losses from specific FLEX Option positions and certain FLEX Option positions may expire worthless. The FLEX Options are listed and trade on an exchange; however, no one can guarantee that a liquid secondary trading market will exist for the FLEX Options. In the event that trading in the FLEX Options is limited or absent, the value of the Fund’s FLEX Options may decrease. In a less liquid market for the FLEX Options, liquidating the FLEX Options may require the payment of a premium (for written FLEX Options) or acceptance of a discounted price (for purchased FLEX Options) and may take longer to complete. A less liquid trading market may adversely impact the value of the FLEX Options and Fund shares and result in the Fund being unable to achieve its investment objective. Less liquidity in the trading of the Fund’s FLEX Options could have an impact on the prices paid or received by the Fund for the FLEX Options in connection with creations and redemptions of the Fund’s shares. Depending on the nature of this impact to pricing, the Fund may be forced to pay more for redemptions (or receive less for creations) than the price at which it currently values the FLEX Options. Such overpayment or under collection could reduce the Fund’s ability to achieve its investment objective. Additionally, in a less liquid market for the FLEX Options, the liquidation of a large number of options may more significantly impact the price. A less liquid trading market may adversely impact the value of the FLEX Options and the value of your investment. The trading in FLEX Options may be less deep and liquid than the market for certain other exchange-traded options, non-customized options or other securities.

 

NEOS Gold High Income ETF | Leverage Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Leverage Risk. When the Fund purchases or sells an instrument or enters into a transaction without investing an amount equal to the full economic exposure of the instrument or transaction, it creates leverage, which can result in the Fund losing more than it originally invested. As a result, these investments may magnify losses to the Fund, and even a small market movement may result in significant losses to the Fund. Leverage may also cause the Fund to be more volatile because it may exaggerate the effect of any increase or decrease in the value of the Fund’s portfolio securities. Options trading involves a degree of leverage and as a result, a relatively small price movement in instruments may result in immediate and substantial losses to the Fund.

 

NEOS Gold High Income ETF | Rolling Options Contract Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Rolling Options Contract Risk. The Fund’s investments in options are subject to risks related to rolling. Rolling occurs when the Fund closes out of an options contract as it nears its expiration and replaces it with a contract that has a later expiration. The Fund does not intend to hold options through expiration, but instead intends to “roll” its positions. When the market for these options is such that the prices are higher in the more distant delivery months than in the nearer delivery months, the sale during the course of the “rolling process” of the more nearby contract would take place at a price that is lower than the price of the more distant contract. This pattern of higher option prices for longer expiration contracts is often referred to as “contango.” Alternatively, when the market for options contracts is such that the prices are higher in the nearer months than in the more distant months, the sale during the course of the “rolling process” of the more nearby contract would take place at a price that is higher than the price of the more distant contract. This pattern of higher options prices for shorter expiration options contracts is referred to as “backwardation.” Extended periods of contango or backwardation have occurred in the past and can in the future cause significant losses for the Fund.

Risk [Text Block]

Wholly-Owned Subsidiary Risk. Changes in the laws of the United States and/or the Cayman Islands, under which the Fund and the Subsidiary, respectively, are organized, could result in the inability of the Fund and/or Subsidiary to operate as described in this Prospectus and could negatively affect the Fund and its shareholders. Unlike the Fund, the Cayman Subsidiary is not an investment company registered under the Investment Company Act of 1940, as amended (the “1940 Act”) and is not subject to all of the investor protections of the 1940 Act. The Fund’s investment in the Cayman Subsidiary is intended to provide the Fund with exposure to Gold ETPs in accordance with applicable rules and regulations. The Fund, by investing in the Cayman Subsidiary when viewed together with the Fund, will operate as though it is subject to the protections offered to investors in registered investment companies with respect to Sections 8 and 18 of the 1940 Act (regarding investment policies, capital structure and leverage), Section 15 of the 1940 Act (regarding investment advisory contract approvals) and Section 17 of the 1940 Act (regarding affiliated transactions and custody). The Fund wholly owns and controls the Cayman Subsidiary, and the Fund and Cayman Subsidiary are both managed by the Adviser. The Board has oversight responsibility for the investment activities of the Fund, including its investment in the Cayman Subsidiary, and the Fund’s role as the sole shareholder of the Cayman Subsidiary. Also, the Adviser in managing the Cayman Subsidiary’s investment portfolio, is subject to the same investment restrictions and operational guidelines that apply to the management of the Fund, when viewed on a consolidated basis.

 

NEOS Gold High Income ETF | Taxation Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Taxation Risk. By investing in Gold ETPs indirectly through the Subsidiary, the Fund will obtain exposure to these securities within the federal tax requirements that apply to the Fund. However, because the Subsidiary is a controlled foreign corporation, any income received from its investments will be passed through to the Fund as ordinary income, which may be taxed at less favorable rates than capital gains. Exceeding this amount may have tax consequences. In order to qualify for the special tax treatment accorded a RIC and its shareholders, the Fund must derive at least 90% of its gross income for each taxable year from “qualifying income,” meet certain asset diversification tests at the end of each taxable quarter, and meet annual distribution requirements. The Fund’s pursuit of its investment strategy will potentially be limited by the Fund’s intention to qualify for such treatment and could adversely affect the Fund’s ability to so qualify. The Fund expects to gain exposure to gold and generate qualifying income by investing a portion of its assets in a wholly-owned subsidiary of the Fund organized under the laws of the Cayman Islands. To comply with the asset diversification test applicable to a RIC, the Fund will limit its investments in such subsidiary to 25% of the Fund’s total assets at the end of each tax quarter. The Fund may, however, exceed this amount from time to time inadvertently or if the Adviser believes doing so is in the best interests of the Fund, provided, however, that the Fund intends to continue to comply with the asset diversification test applicable to RICs. If the Fund’s investments in the subsidiary were to exceed 25% of the Fund’s total assets at the end of a tax quarter, the Fund may no longer be eligible to be treated as a RIC. The Adviser will carefully monitor the Fund’s investments in the subsidiary to ensure that no more than 25% of the Fund’s assets are invested in the subsidiary at the end of each tax quarter. There are no assurances that the IRS will agree with the Fund’s calculation under the asset diversification test which could cause the Fund to fail to qualify as a RIC. If, in any year, the Fund were to fail to qualify for the special tax treatment accorded a RIC and its shareholders, and were ineligible to or were not to cure such failure, the Fund would be taxed in the same manner as an ordinary corporation subject to U.S. federal income tax on all its income at the fund level. The resulting taxes could substantially reduce the Fund’s net assets and the amount of income available for distribution. In addition, in order to requalify for taxation as a RIC, the Fund could be required to recognize unrealized gains, pay substantial taxes and interest, and make certain distributions.

Liquidity Risk. Liquidity risk exists when particular investments of the Fund would be difficult to purchase or sell, possibly preventing the Fund from selling such illiquid securities at an advantageous time or price, or possibly requiring the Fund to dispose of other investments at unfavorable times or prices in order to satisfy its obligations.

Prospectus [Line Items]  
Risk [Text Block]

New Fund Risk. The Fund is new with a limited operating history. If the Fund does not grow large in size, it will be at greater risk than larger funds of wider bid-ask spreads for its shares, trading at a greater premium or discount to NAV, liquidation and/or a stop to trading. Any resulting liquidation of the Fund could cause the Fund to incur elevated transaction costs for the Fund and negative tax consequences for its shareholders.

 

NEOS Gold High Income ETF | Gold Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Gold Risk. The price of gold may be volatile and derivative contracts linked to gold may be highly sensitive to the price of gold. The price of gold can be significantly affected by international monetary and political developments such as currency devaluation or revaluation, central bank movements, economic and social conditions within a country, transactional or trade imbalances, or trade or currency restrictions between countries. Gold prices may be influenced by the fact that physical gold has sales commission, storage, insurance, and auditing expenses, which may tend to reduce trading and liquidity.

 

NEOS Gold High Income ETF | Gold Tax Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Gold Tax Risk. By investing in Gold ETPs indirectly through the Subsidiary, the Fund will obtain exposure to gold within the federal tax requirements that apply to the Fund. However, because the Subsidiary is a controlled foreign corporation organized under the laws of the Cayman Islands, any income received by the Fund from its investments in the Subsidiary will be passed through to the Fund as ordinary income, which may be taxed at less favorable rates than capital gains.

 

A direct investment by the Fund in a Gold ETP will generally be treated as a direct investment in gold for U.S. federal income tax purposes. In order to qualify for the special tax treatment accorded a regulated investment company (“RIC”) and its shareholders, Subchapter M of the Internal Revenue Code of 1986, as amended (the “Code”) requires, among other things, that at least 90% of the Fund’s income be “qualifying income.” Although the income from a direct investment in Gold ETPs is not treated as qualifying income, the income generated from the Fund’s options on the Gold ETPs is considered qualifying income because the Gold ETPs are securities for purposes of Section 851(b)(2)) of the Code

 

To the extent the IRS disagrees with this view, then the Fund may fail to qualify as a RIC under the Code. If, in any year, the Fund fails to qualify as a RIC and was ineligible to or was not able to cure such failure, the Fund would be taxed in the same manner as an ordinary corporation and subject to U.S. federal income tax on all its income at the fund level. The resulting taxes could substantially reduce the Fund’s net assets and the amount of income available for distribution. In addition, in order to requalify for taxation as a RIC, the Fund could be required to recognize unrealized gains, pay substantial taxes and interest, and make certain distributions. See “Options Risk” and “Derivatives Risk” below for additional risks regarding the Fund’s options strategy.

 

NEOS Gold High Income ETF | Exchange Traded Product (ETP) Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Exchange Traded Product (ETP) Risk. The Fund invests in Gold ETPs. Through its positions in Gold ETPs, the Fund generally will be subject to the risks associated with such vehicle’s investments, including the possibility that the value of the securities or instruments held by or linked to a Gold ETP could decrease. The Gold ETPs in which the Fund invests are not registered, nor are they required to be registered, as investment companies subject to the 1940 Act and, therefore, are not subject to the regulatory scheme of the 1940 Act. Additionally, the Gold ETPs are not commodity pools for purposes of the Commodities Exchange Act (“CEA”) and the service providers are not subject to regulation by the Commodities Futures Exchange Commission as a Commodity Pool Operator (“CPO”) or Commodity Trading Adviser in connection with the shares of the Gold ETPs and, therefore, shareholders do not have the protections provided to investors in CEA regulated instruments or CPOs. When the Fund invests in a Gold ETP, in addition to directly bearing the expenses associated with its own operations, it also will bear a pro rata portion of the Gold ETP’s expenses (including operating costs and management fees).

 

There is also a risk that a Gold ETP’s gold bars held by its custodian could be lost, damaged, or stolen. A Gold ETP’s access to its gold bars could be restricted by natural events (such as earthquakes) or human actions (such as a terrorist attack). This would adversely impact the operations of the Gold ETPs and thus, the Fund’s investments in the Gold ETPs.

NEOS Gold High Income ETF | Fixed Income Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Fixed Income Risk. The value of the Fund’s investments in fixed income securities that serve as collateral to transactions involving options will fluctuate with changes in interest rates. Typically, a rise in interest rates causes a decline in the value of fixed income securities owned by the Fund. In general, the market price of fixed income securities with longer maturities will increase or decrease more in response to changes in interest rates than shorter- term securities. Other risk factors include credit risk (the debtor may default), extension risk (an issuer may exercise its right to repay principal on a fixed rate obligation held by the Fund later than expected), and prepayment risk (the debtor may pay its obligation early, reducing the amount of interest payments). These risks could affect the value of a particular investment by the Fund, possibly causing the Fund’s share price and total return to be reduced and fluctuate more than other types of investments.

Active Management Risk. The Fund is actively managed, which means that investment decisions are made based on investment views. There is no guarantee that the investment views will produce the desired results or expected returns, which may cause the Fund to fail to meet its investment objective or to underperform its benchmark index or funds with similar investment objectives and strategies. Furthermore, active trading that can accompany active management may result in high portfolio turnover, which may have a negative impact on performance. Active trading may result in higher brokerage costs or mark-up charges, which are ultimately passed on to shareholders of the Fund. Active trading may also result in adverse tax consequences.

Concentration Risk. Since the Fund will invest in up to 100% of the constituents of the International Index and/or one or more International Underlying ETFs that tracks the International Index, the Fund itself will be concentrated in certain regions, economies, countries, markets, industries or sectors to the same extent as the International Index. The Fund may be susceptible to an increased risk of loss, including losses due to adverse events that affect the Fund’s investments more than the market as a whole, to the extent that the Fund’s investments are concentrated in the securities of a particular issuer or issuers, country, group of countries, region, market, industry, group of industries, sector or asset class.

Derivatives Risk. Options are a derivative investment. The use of derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities and other traditional investments. These risks include (i) the risk that the counterparty to a derivative transaction may not fulfil its contractual obligations; (ii) risk of mispricing or improper valuation; and (iii) the risk that changes in the value of the derivative may not correlate perfectly with the underlying asset, rate or index. Derivative prices are highly volatile and may fluctuate substantially during a short period of time. Such prices are influenced by numerous factors that affect the markets, including, but not limited to: changing supply and demand relationships; government programs and policies; national and international political and economic events, changes in interest rates, inflation and deflation and changes in supply and demand relationships.

●Trading Issues. Trading in Shares on the Exchange may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in Shares inadvisable, such as extraordinary market volatility. There can be no assurance that Shares will continue to meet the listing requirements of the Exchange which may result in the Shares being delisted. An active trading market for the Shares may not be developed or maintained. If the Shares are traded outside a collateralized settlement system, the number of financial institutions that can act as Authorized Participants that can post collateral on an agency basis is limited, which may limit the market for the Shares.

 

NEOS MSCI EAFE High Income ETF | Market Price Variance Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]
●Market Price Variance Risk. The market prices of Shares will fluctuate in response to changes in NAV and supply and demand for Shares and will include a “bid-ask spread” charged by the exchange specialists, market makers or other participants that trade the Shares. There may be times when the market price and the NAV vary significantly. This means that Shares may trade at a discount to NAV.

 

○In times of market stress, market makers may step away from their role market making in the Shares and in executing trades, which can lead to differences between the market value of the Shares and the Fund’s NAV.

 

○The market price of the Shares may deviate from the Fund’s NAV, particularly during times of market stress, with the result that investors may pay significantly more or significantly less for the Shares than the Fund’s NAV, which is reflected in the bid and ask price for the Shares or in the closing price.

 

○In stressed market conditions, the market for the Shares may become less liquid in response to the deteriorating liquidity of the Fund’s portfolio. This adverse effect on the liquidity of the Shares may, in turn, lead to differences between the market value of the Shares and the Fund’s NAV.

 

NEOS MSCI EAFE High Income ETF | Authorized Participant Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]
●Authorized Participant Risk. Only an Authorized Participant may engage in creation or redemption transactions directly with the Fund. The Fund has a limited number of institutions that may act as an Authorized Participant on an agency basis (i.e., on behalf of other market participants). To the extent that Authorized Participants exit the business or are unable to proceed with creation or redemption orders with respect to the Fund and no other Authorized Participant is able to step forward to create or redeem Creation Units, Fund shares may be more likely to trade at a premium or discount to net asset value and possibly face trading halts or delisting. Authorized Participant concentration risk may be heightened for securities or instruments that have lower trading volumes.

 

Additionally, purchases and redemptions of creation units primarily with cash rather than through in-kind delivery of portfolio securities may cause the Fund to incur certain costs, including brokerage costs or taxable gains or losses that it might not have incurred if it made a redemption in-kind, and therefore decrease the Fund’s NAV to the extent not offset by a transaction fee payable by an AP.

Market and Geopolitical Risk. The increasing interconnectivity between global economies and financial markets increases the likelihood that events or conditions in one region or financial market may adversely impact issuers in a different country, region or financial market. Securities in the Fund’s portfolio may underperform due to inflation (or expectations for inflation), interest rates, global demand for particular products or resources, natural disasters, climate change and climate-related events, pandemics, epidemics, terrorism, international conflicts, regulatory events and governmental or quasi-governmental actions. The occurrence of global events similar to those in recent years may result in market volatility and may have long term effects on financial markets worldwide.

 

NEOS MSCI EAFE High Income ETF | Options Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Options Risk. Buying and selling (writing) options are speculative activities and entail greater than ordinary investment risks. Options enable the Fund to purchase exposure that is significantly greater than the premium paid. Consequently, the value of such options can be volatile, and a small investment in options can have a large impact on the performance of the Fund. The Fund risks losing all or part of the cash paid (premiums) for purchasing options. Even a small decline in the value of a reference asset underlying call options or a small increase in the value of a reference asset underlying put options can result in the entire investment in such options being lost. The Fund’s options also may fail to track the performance of their underlying reference asset, which may limit the effectiveness of the Fund’s strategy. The potential loss from written options can exceed the Fund’s initial investment in such options and could be unlimited.

Sector Risk. Sector risk is the possibility that securities within the same sectors will decline in price due to sector-specific market or economic developments. If the Fund invests more heavily in a particular sector, through the underlying constituents of the International Index or International Underlying ETFs, the value of its shares may be especially sensitive to factors and economic risks that specifically affect that sector. As a result, the Fund’s share price may fluctuate more widely than the value of shares of a fund that invests in a broader range of sectors.

Tax Risk. The Fund invests in derivatives. The federal income tax treatment of a derivative may not be as favorable as a direct investment in an underlying asset. Derivatives may produce taxable income and taxable realized gain. Derivatives may adversely affect the timing, character and amount of income the Fund realizes from its investments. As a result, a larger portion of the Fund’s distributions may be treated as ordinary income rather than as capital gains. In addition, certain derivatives are subject to mark-to-market or straddle provisions of the Internal Revenue Code of 1986, as amended (the “Internal Revenue Code”). If such provisions are applicable, there could be an increase (or decrease) in the amount of taxable dividends paid by the Fund.

Valuation Risk. The price the Fund could receive upon the sale of a security or other asset may differ from the Fund’s valuation of the security or other asset and from the value used by the Reference Index, particularly for securities or other assets that trade in low volume or volatile markets or that are valued using a fair value methodology as a result of trade suspensions or for other reasons. In addition, the value of the securities or other assets in the Fund’s portfolio may change on days or during time periods when shareholders will not be able to purchase or sell the Fund’s shares. Authorized Participants who purchase or redeem Fund shares on days when the Fund is holding fair-valued securities may receive fewer or more shares, or lower or higher redemption proceeds, than they would have received had the Fund not fair-valued securities or used a different valuation methodology. The Fund’s ability to value investments may be impacted by technological issues or errors by pricing services or other third-party service providers.

Underlying ETF and Index Risk. The Fund may invest in the securities of other investment companies including the International Underlying ETFs. If the Fund invests in and, thus, is a shareholder of, another investment company, the Fund’s shareholders will indirectly bear the Fund’s proportionate share of the fees and expenses paid by such other investment company, including advisory fees, in addition to both the management fees payable directly by the Fund to the Fund’s own investment adviser and the other expenses that the Fund bears directly in connection with the Fund’s own operations. Each of the International Underlying ETFs is subject to similar risk as the Fund.

Cybersecurity Risk. The computer systems, networks and devices used by the Fund and its service providers to carry out routine business operations employ a variety of protections designed to limit damage or interruption from computer viruses, network failures, computer and telecommunication failures, infiltration by unauthorized persons and security breaches. Despite the various protections utilized by the Fund and its service providers, systems, networks, or devices potentially can be breached. The Fund and its shareholders could be negatively impacted as a result of a cybersecurity breach.

 

Cybersecurity breaches can include unauthorized access to systems, networks, or devices; infection from computer viruses or other malicious software code; and attacks that shut down, disable, slow, or otherwise disrupt operations, business processes, or website access or functionality. Cybersecurity breaches may cause disruptions and impact the Fund’s business operations, potentially resulting in financial losses; interference with the Fund’s ability to calculate its NAV; impediments to trading; the inability of the Fund, the adviser, and other service providers to transact business; violations of applicable privacy and other laws; regulatory fines, penalties, reputational damage, reimbursement or other compensation costs, or additional compliance costs; as well as the inadvertent release of confidential information.

 

 

Similar adverse consequences could result from cybersecurity breaches affecting issuers of securities in which the Fund invests; counterparties with which the Fund engages in transactions; governmental and other regulatory authorities; exchange and other financial market operators, banks, brokers, dealers, insurance companies, and other financial institutions (including financial intermediaries and service providers for the Fund’s shareholders); and other parties. In addition, substantial costs may be incurred by these entities in order to prevent any cybersecurity breaches in the future.

Index Risk. Since the Fund will invest in International Underlying ETFs and/or t constituents in a manner to generally track the Underlying Index, the Fund even though it is actively managed nevertheless will be subject to index risks.

 

An index fund has operating and other expenses while an index does not. As a result, while the Fund when selecting equity securities will attempt to track the International Index as closely as possible, it will tend to underperform the index to some degree over time. If an index fund is properly correlated to its stated index, the Fund will perform poorly when the index performs poorly.

 

There is no guarantee that the Fund’s equity securities investment results will have a high degree of correlation to those of the International Index or that the Fund will achieve its investment objective. Market disruptions or high volatility, other unusual market circumstances and regulatory restrictions could have an adverse effect on the Fund’s ability to adjust its exposure to the required levels in order to track the International Index. Errors in index data, index computations or the construction of the International Index in accordance with its methodology may occur from time to time and may not be identified and corrected by the index provider for a period of time or at all, which may have an adverse impact on the Fund and its shareholders. Unusual market conditions may cause the index provider to postpone a scheduled rebalance, which could cause the International Index to vary from its normal or expected composition.

New Fund Risk. The Fund is a new fund, with limited operating history, which may result in additional risks for investors in the Fund. There can be no assurance that the Fund will grow to or maintain an economically viable size, in which case the Board of Trustees may determine to liquidate the Fund. While shareholder interests will be the paramount consideration, the timing of any liquidation may not be favorable to certain individual shareholders.

 

NEOS MSCI EAFE High Income ETF | Foreign Securities Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Foreign Securities Risk. Foreign investments often involve special risks not present in U.S. investments that can increase the chances that the Fund will lose money. These risks include:

 

●The Fund generally holds its foreign securities and cash in foreign banks and securities depositories, which may be recently organized or new to the foreign custody business and may be subject to only limited or no regulatory oversight.

 

●Changes in foreign currency exchange rates can affect the value of the Fund’s portfolio.

 

●The economies of certain foreign markets may not compare favorably with the economy of the United States with respect to such issues as growth of gross national product, reinvestment of capital, resources and balance of payments position.

 

●The governments of certain countries, or the U.S. Government with respect to certain countries, may prohibit or impose substantial restrictions through capital controls and/or sanctions on foreign investments in the capital markets or certain industries in those countries, which may prohibit or restrict the ability to own or transfer currency, securities, derivatives or other assets.

 

●Many foreign governments do not supervise and regulate stock exchanges, brokers and the sale of securities to the same extent as does the United States and may not have laws to protect investors that are comparable to U.S. securities laws.

 

●Settlement and clearance procedures in certain foreign markets may result in delays in payment for or delivery of securities not typically associated with settlement and clearance of U.S. investments.

 

●The Fund’s claims to recover foreign withholding taxes may not be successful, and if the likelihood of recovery of foreign withholding taxes materially decreases, due to, for example, a change in tax regulation or approach in the foreign country, accruals in the Fund’s net asset value for such refunds may be written down partially or in full, which will adversely affect the Fund’s net asset value.

 

●The European financial markets have recently experienced volatility and adverse trends due to concerns about economic downturns in, or rising government debt levels of, several European countries. These events may spread to other countries in Europe. These events may affect the value and liquidity of certain of the Fund’s investments.

Foreign Currency Risk. As a result of the Fund’s investments in securities denominated in, and/or receiving revenues in, foreign currencies, the Fund will be subject to currency risk. Currency risk is the risk that foreign currencies will decline in value relative to the U.S. dollar, in which case, the dollar value of an investment in the Fund would be adversely affected.

Geographic Concentration Risk. The risk that events negatively affecting the fiscal stability of a particular country or region in which the Fund focuses its investments will cause the value of the Fund’s shares to decrease, perhaps significantly. To the extent the Fund concentrates its assets in a particular country or region, the Fund is more vulnerable to financial, economic or other political developments in that country or region as compared to a fund that does not concentrate holdings in a particular country or region.

Active Management Risk. The Fund is actively managed, which means that investment decisions are made based on investment views. There is no guarantee that the investment views will produce the desired results or expected returns, which may cause the Fund to fail to meet its investment objective or to underperform its benchmark index or funds with similar investment objectives and strategies. Furthermore, active trading that can accompany active management may result in high portfolio turnover, which may have a negative impact on performance. Active trading may result in higher brokerage costs or mark-up charges, which are ultimately passed on to shareholders of the Fund. Active trading may also result in adverse tax consequences.

 

NEOS MLP & Energy Infrastructure High Income ETF | Concentration Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Concentration Risk. Since the Fund will invest in up to 100% of the constituents of the MLP & Energy Infrastructure Index, the Fund itself will be concentrated in certain regions, economies, countries, markets, industries or sectors to the same extent as the MLP & Energy Infrastructure Index. The Fund may be susceptible to an increased risk of loss, including losses due to adverse events that affect the Fund’s investments more than the market as a whole, to the extent that the Fund’s investments are concentrated in the securities of a particular issuer or issuers, country, group of countries, region, market, industry, group of industries, sector or asset class.

 

NEOS MLP & Energy Infrastructure High Income ETF | Derivatives Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Derivatives Risk. Options are a derivative investment. The use of derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities and other traditional investments. These risks include (i) the risk that the counterparty to a derivative transaction may not fulfil its contractual obligations; (ii) risk of mispricing or improper valuation; and (iii) the risk that changes in the value of the derivative may not correlate perfectly with the underlying asset, rate or index. Derivative prices are highly volatile and may fluctuate substantially during a short period of time. Such prices are influenced by numerous factors that affect the markets, including, but not limited to: changing supply and demand relationships; government programs and policies; national and international political and economic events, changes in interest rates, inflation and deflation and changes in supply and demand relationships.

  ● Not Individually Redeemable. The Fund’s shares (“Shares”) are not redeemable by retail investors and may be redeemed only by Authorized Participants at net asset value (“NAV”) and only in Creation Units. A retail investor generally incurs brokerage costs when selling shares.
NEOS MLP & Energy Infrastructure High Income ETF | Trading Issues [Member]  
Prospectus [Line Items]  
Risk [Text Block]
  ● Trading Issues. Trading in Shares on the Exchange may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in Shares inadvisable, such as extraordinary market volatility. There can be no assurance that Shares will continue to meet the listing requirements of the Exchange which may result in the Shares being delisted. An active trading market for the Shares may not be developed or maintained. If the Shares are traded outside a collateralized settlement system, the number of financial institutions that can act as Authorized Participants that can post collateral on an agency basis is limited, which may limit the market for the Shares.
NEOS MLP & Energy Infrastructure High Income ETF | Market Price Variance Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]
  ● Market Price Variance Risk. The market prices of Shares will fluctuate in response to changes in NAV and supply and demand for Shares and will include a “bid-ask spread” charged by the exchange specialists, market makers or other participants that trade the Shares. There may be times when the market price and the NAV vary significantly. This means that Shares may trade at a discount to NAV.
  ○ In times of market stress, market makers may step away from their role market making in the Shares and in executing trades, which can lead to differences between the market value of the Shares and the Fund’s NAV.
  ○ The market price of the Shares may deviate from the Fund’s NAV, particularly during times of market stress, with the result that investors may pay significantly more or significantly less for the Shares than the Fund’s NAV, which is reflected in the bid and ask price for the Shares or in the closing price.
  ○ In stressed market conditions, the market for the Shares may become less liquid in response to the deteriorating liquidity of the Fund’s portfolio. This adverse effect on the liquidity of the Shares may, in turn, lead to differences between the market value of the Shares and the Fund’s NAV.

 

NEOS MLP & Energy Infrastructure High Income ETF | Authorized Participant Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Authorized Participant Risk. Only an Authorized Participant may engage in creation or redemption transactions directly with the Fund. The Fund has a limited number of institutions that may act as an Authorized Participant on an agency basis (i.e., on behalf of other market participants). To the extent that Authorized Participants exit the business or are unable to proceed with creation or redemption orders with respect to the Fund and no other Authorized Participant is able to step forward to create or redeem Creation Units, Fund shares may be more likely to trade at a premium or discount to net asset value and possibly face trading halts or delisting. Authorized Participant concentration risk may be heightened for securities or instruments that have lower trading volumes.

 

Additionally, purchases and redemptions of creation units primarily with cash rather than through in-kind delivery of portfolio securities may cause the Fund to incur certain costs, including brokerage costs or taxable gains or losses that it might not have incurred if it made a redemption in-kind, and therefore decrease the Fund’s NAV to the extent not offset by a transaction fee payable by an AP.

Issuer Risk. Changes in the financial condition or credit rating of an issuer or counterparty, changes in specific economic or political conditions that affect a particular type of security or issuer, and changes in general economic or political conditions can affect a security’s or instrument’s value. The values of securities of smaller, less well-known issuers can be more volatile than those of larger issuers. Issuer-specific events can have a negative impact on the value of the Fund.

 

NEOS MLP & Energy Infrastructure High Income ETF | Market and Geopolitical Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Market and Geopolitical Risk. The increasing interconnectivity between global economies and financial markets increases the likelihood that events or conditions in one region or financial market may adversely impact issuers in a different country, region or financial market. Securities in the Fund’s portfolio may underperform due to inflation (or expectations for inflation), interest rates, global demand for particular products or resources, natural disasters, climate change and climate-related events, pandemics, epidemics, terrorism, international conflicts, regulatory events and governmental or quasi-governmental actions. The occurrence of global events similar to those in recent years may result in market volatility and may have long term effects on financial markets worldwide.

 

NEOS MLP & Energy Infrastructure High Income ETF | Options Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Options Risk. Buying and selling (writing) options are speculative activities and entail greater than ordinary investment risks. Options enable the Fund to purchase exposure that is significantly greater than the premium paid. Consequently, the value of such options can be volatile, and a small investment in options can have a large impact on the performance of the Fund. The Fund risks losing all or part of the cash paid (premiums) for purchasing options. Even a small decline in the value of a reference asset underlying call options or a small increase in the value of a reference asset underlying put options can result in the entire investment in such options being lost. The Fund’s options also may fail to track the performance of their underlying reference asset, which may limit the effectiveness of the Fund’s strategy. The potential loss from written options can exceed the Fund’s initial investment in such options and could be unlimited

 

NEOS MLP & Energy Infrastructure High Income ETF | Tax Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Tax Risk. The Fund invests in derivatives. The federal income tax treatment of a derivative may not be as favorable as a direct investment in an underlying asset. Derivatives may produce taxable income and taxable realized gain. Derivatives may adversely affect the timing, character and amount of income the Fund realizes from its investments. As a result, a larger portion of the Fund’s distributions may be treated as ordinary income rather than as capital gains. In addition, certain derivatives are subject to mark-to-market or straddle provisions of the Internal Revenue Code of 1986, as amended (the “Internal Revenue Code”). If such provisions are applicable, there could be an increase (or decrease) in the amount of taxable dividends paid by the Fund.

 

NEOS MLP & Energy Infrastructure High Income ETF | Valuation Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Valuation Risk. The price the Fund could receive upon the sale of a security or other asset may differ from the Fund’s valuation of the security or other asset and from the value used by the Reference Index, particularly for securities or other assets that trade in low volume or volatile markets or that are valued using a fair value methodology as a result of trade suspensions or for other reasons. In addition, the value of the securities or other assets in the Fund’s portfolio may change on days or during time periods when shareholders will not be able to purchase or sell the Fund’s shares. Authorized Participants who purchase or redeem Fund shares on days when the Fund is holding fair-valued securities may receive fewer or more shares, or lower or higher redemption proceeds, than they would have received had the Fund not fair-valued securities or used a different valuation methodology. The Fund’s ability to value investments may be impacted by technological issues or errors by pricing services or other third- party service providers.

Cybersecurity Risk. The computer systems, networks and devices used by the Fund and its service providers to carry out routine business operations employ a variety of protections designed to limit damage or interruption from computer viruses, network failures, computer and telecommunication failures, infiltration by unauthorized persons and security breaches. Despite the various protections utilized by the Fund and its service providers, systems, networks, or devices potentially can be breached. The Fund and its shareholders could be negatively impacted as a result of a cybersecurity breach.

 

Cybersecurity breaches can include unauthorized access to systems, networks, or devices; infection from computer viruses or other malicious software code; and attacks that shut down, disable, slow, or otherwise disrupt operations, business processes, or website access or functionality. Cybersecurity breaches may cause disruptions and impact the Fund’s business operations, potentially resulting in financial losses; interference with the Fund’s ability to calculate its NAV; impediments to trading; the inability of the Fund, the adviser, and other service providers to transact business; violations of applicable privacy and other laws; regulatory fines, penalties, reputational damage, reimbursement or other compensation costs, or additional compliance costs; as well as the inadvertent release of confidential information.

 

NEOS MLP & Energy Infrastructure High Income ETF | FLEX Options Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

FLEX Options Risk. Trading FLEX Options involves risks different from, or possibly greater than, the risks associated with investing directly in securities. The Fund may experience losses from specific FLEX Option positions and certain FLEX Option positions may expire worthless. The FLEX Options are listed and trade on an exchange; however, no one can guarantee that a liquid secondary trading market will exist for the FLEX Options. In the event that trading in the FLEX Options is limited or absent, the value of the Fund’s FLEX Options may decrease. In a less liquid market for the FLEX Options, liquidating the FLEX Options may require the payment of a premium (for written FLEX Options) or acceptance of a discounted price (for purchased FLEX Options) and may take longer to complete. A less liquid trading market may adversely impact the value of the FLEX Options and Fund shares and result in the Fund being unable to achieve its investment objective. Less liquidity in the trading of the Fund’s FLEX Options could have an impact on the prices paid or received by the Fund for the FLEX Options in connection with creations and redemptions of the Fund’s shares. Depending on the nature of this impact to pricing, the Fund may be forced to pay more for redemptions (or receive less for creations) than the price at which it currently values the FLEX Options. Such overpayment or under collection could reduce the Fund’s ability to achieve its investment objective. Additionally, in a less liquid market for the FLEX Options, the liquidation of a large number of options may more significantly impact the price. A less liquid trading market may adversely impact the value of the FLEX Options and the value of your investment. The trading in FLEX Options may be less deep and liquid than the market for certain other exchange-traded options, non-customized options or other securities.

  

NEOS MLP & Energy Infrastructure High Income ETF | Liquidity Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Liquidity Risk.  Although MLPs trade on national securities exchanges, certain MLP securities may trade less frequently than those of larger companies due to their smaller capitalizations. At times, due to limited trading volumes of certain MLPs, the prices of such MLPs may display abrupt or erratic movements. Moreover, it may be more difficult for the Fund to buy and sell significant amounts of such securities without an unfavorable impact on prevailing market prices. The Fund’s investment in securities that are less actively traded or over time experience decreased trading volume may restrict its ability to take advantage of other market opportunities or to dispose of securities at a fair price at the times when the Adviser believes it is desirable to do so. This also may affect adversely the Fund’s ability to make dividend distributions to you. Certain MLP securities may trade less frequently than those of larger companies due to their smaller capitalizations. In the event certain MLP securities experience limited trading volumes, the prices of such MLPs may display abrupt or erratic movements at times. Additionally, it may be more difficult for the Fund to buy and sell significant amounts of such securities without an unfavorable impact on prevailing market prices. As a result, these securities may be difficult to dispose of at a fair price at the times when the Fund is required to do so based on changes in the Reference Index or to fund redemptions. Liquidity risk is heightened in a changing interest rate or volatile environment.

Index Risk. Since the Fund will invest in constituents in a manner to generally track the MLP & Energy Infrastructure Index, the Fund even though it is actively managed nevertheless will be subject to index risks.

 

An index fund has operating and other expenses while an index does not. As a result, when selecting securities the Fund will attempt to track the MLP & Energy Infrastructure Index, it will tend to underperform the index to some degree over time.

Risk [Text Block]

Tax Status of the Fund. If, in any year, the Fund fails to qualify as a registered investment company under the applicable tax laws, the Fund would be taxed as an ordinary corporation for federal income tax purposes. This differs from most investment companies, which elect to be treated as “regulated investment companies” under the Code in order to avoid paying entity level income taxes. If the Fund failed to qualify, it will be obligated to pay applicable federal and state corporate income taxes on its taxable income as opposed to most other investment companies which are not so obligated and may be liable for the corporate alternative minimum tax and for an excise tax on net redemptions incurred within a taxable year.

Prospectus [Line Items]  
Risk [Text Block]

Deferred Tax Liability. Cash distributions from an MLP to the Fund that exceed the Fund’s allocable share of such MLP’s net taxable income are considered a tax-deferred return of capital that will reduce the Fund’s adjusted tax basis in the equity securities of the MLP. These reductions in the Fund’s adjusted tax basis in the MLP equity securities will increase the amount of gain (or decrease the amount of loss) recognized by the Fund on a subsequent sale of the securities. The Fund will accrue deferred income taxes for any future tax liability associated with (i) that portion of MLP distributions considered to be a tax-deferred return of capital as well as (ii) capital appreciation of its investments. Upon the sale of an MLP security, the Fund may be liable for previously deferred taxes. The Fund’s accrued deferred tax liability will be reflected each day in the Fund’s net asset value (“NAV”). Increases in deferred tax liability will decrease NAV. Conversely, decreases in deferred liability will increase NAV, but only to the extent of previously accrued deferred tax liability, i.e., no deferred tax asset will be accrued. The Fund will rely to a large extent on information provided by the MLPs, which is not necessarily timely, to estimate deferred tax liability for purposes of financial statement reporting and determining the NAV. From time to time, the Adviser will modify the estimates or assumptions regarding the Fund’s deferred tax liability as new information becomes available. The Fund’s estimates regarding its deferred tax liability are made in good faith, however, the daily estimate of the Fund’s deferred tax liability used to calculate the Fund’s NAV could vary significantly from the Fund’s actual tax liability.]

MLP Risk. Investments in securities of MLPs involve risks that differ from investments in common stock including risks related to limited control and limited rights to vote on matters affecting the MLP, risks related to potential conflicts of interest between the MLP and the MLP’s general partner, dilution risks and risks related to the general partner’s right to require unit-holders to sell their common units at an undesirable time or price due to regulatory changes and cash flow risks. MLP common units and other equity securities can be affected by macro-economic and other factors affecting the stock market in general, expectations of interest rates, investor sentiment towards MLPs or the energy sector, changes in a particular issuer’s financial condition, or unfavorable or unanticipated poor performance of a particular issuer (in the case of MLPs, generally measured in terms of distributable cash flow). MLPs holding credit-related investments are subject to interest rate risk and the risk of default on payment obligations by debt issuers. Prices of common units of individual MLPs and other equity securities also can be affected by fundamentals unique to the partnership or company, including cash flow growth, cash generating power and distribution coverage.

MLP Tax Risk. MLPs generally do not pay U.S. federal income tax at the partnership level, although under the centralized audit regime, MLPs are audited and imputed underpayments at the partnership level. A change in current tax law, or a change in the underlying business mix of a given MLP, could result in an MLP being treated as a corporation for U.S. federal income tax purposes, which would result in such MLP being required to pay U.S. federal income tax on its taxable income. The classification of an MLP as a corporation for U.S. federal income tax purposes would have the effect of reducing the amount of cash available for distribution by the MLP and could result in a reduction in the value of your investment in the Fund.

 

NEOS MLP & Energy Infrastructure High Income ETF | Energy Infrastructure Risks [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Energy Infrastructure Risks. The Fund invests primarily in energy infrastructure companies. Energy infrastructure companies are subject to risks specific to the industry they serve. To the extent that the Fund continues to be concentrated in the energy sector, the Fund will be sensitive to changes in, and its performance will depend to a greater extent on, the overall condition of the energy sector. Many MLPs and companies operate within the energy sector. Therefore, a substantial portion of the MLPs and companies in which the Fund invests are engaged in the energy sector of the economy. As a result, a downturn in the energy sector of the economy, adverse political, legislative or regulatory developments or other events could have a larger impact on the Fund than on an investment company that does not invest a substantial portion of its assets in the energy sector. At times, the performance of securities of companies in the energy sector may lag the performance of other sectors or the broader market as a whole. The price of oil, natural gas and other fossil fuels may decline and/or experience significant volatility, which could adversely impact companies operating in the energy sector. In addition, there are several specific risks associated with investments in the energy sector, including the following:

 

  ● the energy sector is highly regulated. MLPs and companies operating in the energy sector are subject to significant regulation of nearly every aspect of their operations by federal, state and local governmental agencies;
  ● MLPs and companies operating in the energy sector may be affected by fluctuations in the prices of energy commodities, including, for example, natural gas, natural gas liquids, crude oil and coal, in the short- and long-term;
  ● MLPs and companies engaged in the exploration, development, management or production of energy commodities face the risk that commodity reserves are depleted over time, with the potential associated effect of causing the market value of the MLP to decline over time;
  ● MLPs and companies operating in the energy sector could be adversely affected by reductions in the supply of or demand for energy commodities;
  ● extreme weather or other natural disasters could impact the value of MLPs operating in the energy sector;
  ● the abilities of MLPs and companies operating in the energy sector to grow and to increase cash distributions to unitholders can be highly dependent on their ability to make acquisitions that result in an increase in cash flows;
  ● rising interest rates which could adversely impact the financial performance and/or the present value of cash flow of MLPs and companies operating in the energy sector; and
  ● MLPs and companies operating in the energy sector are subject to many dangers inherent in the production, exploration, management, transportation, processing and distribution of natural gas, natural gas liquids, crude oil, refined petroleum and petroleum products and other hydrocarbons. In addition, threats of attack by terrorists on energy assets could impact the market for MLPs operating in the energy sector.

GDRs are certificates issued by an international bank that generally are traded and denominated in the currencies of countries other than the home country of the issuer of the underlying shares. ADRs and GDRs may be subject to certain of the risks associated with direct investments in the securities of foreign companies, such as currency risk, political, economic, regulatory, diplomatic, and market risk, because their values depend on the performance of the non-dollar denominated underlying foreign securities. Moreover, ADRs and GDRs may not track the price of the underlying foreign securities on which they are based, and their value may change materially at times when U.S. markets are not open for trading.

Risk [Text Block]

Active Management Risk. The Fund is actively managed, which means that investment decisions are made based on investment views. There is no guarantee that the investment views will produce the desired results or expected returns, which may cause the Fund to fail to meet its investment objective or to underperform its benchmark index or funds with similar investment objectives and strategies. Furthermore, active trading that can accompany active management may result in high portfolio turnover, which may have a negative impact on performance. Active trading may result in higher brokerage costs or mark-up charges, which are ultimately passed on to shareholders of the Fund. Active trading may also result in adverse tax consequences.

 

NEOS Ethereum High Income ETF | Concentration Risk [Member]

Risk [Text Block]

Concentration Risk. Because the Fund invests more than 25% of its assets in Spot Ether ETPs and options on Ether-related instruments, the Fund’s net asset value may fluctuate more than that of a fund that does not concentrate in Spot Ether ETPs and options on Ether-related instruments.

 

NEOS Ethereum High Income ETF | Derivatives Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Derivatives Risk. Options are a derivative investment. The use of derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities and other traditional investments. These risks include (i) the risk that the counterparty to a derivative transaction may not fulfil its contractual obligations; (ii) risk of mispricing or improper valuation; and (iii) the risk that changes in the value of the derivative may not correlate perfectly with the underlying asset, rate or index. Derivative prices are highly volatile and may fluctuate substantially during a short period of time. Such prices are influenced by numerous factors that affect the markets, including, but not limited to: changing supply and demand relationships; government programs and policies; national and international political and economic events, changes in interest rates, inflation and deflation and changes in supply and demand relationships.

Exchange Traded Funds (“ETFs”) Risk. The Fund is structured as an ETF. As a result, the Fund is subject to special risks, including:

 

NEOS Ethereum High Income ETF | Not Individually Redeemable [Member]  
Prospectus [Line Items]  
Risk [Text Block]
●Not Individually Redeemable. The Fund’s shares (“Shares”) are not redeemable by retail investors and may be redeemed only by Authorized Participants at net asset value (“NAV”) and only in Creation Units. A retail investor generally incurs brokerage costs when selling shares.

 

NEOS Ethereum High Income ETF | Trading Issues [Member]  
Prospectus [Line Items]  
Risk [Text Block]
●Trading Issues. Trading in Shares on CBOE BZX Exchange, Inc. (the “Exchange”) may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in Shares inadvisable, such as extraordinary market volatility. There can be no assurance that Shares will continue to meet the listing requirements of the Exchange which may result in the Shares being delisted. An active trading market for the Shares may not be developed or maintained. If the Shares are traded outside a collateralized settlement system, the number of financial institutions that can act as Authorized Participants that can post collateral on an agency basis is limited, which may limit the market for the Shares.

 

NEOS Ethereum High Income ETF | Market Price Variance Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]
●Market Price Variance Risk. The market prices of Shares will fluctuate in response to changes in NAV and supply and demand for Shares and will include a “bid-ask spread” charged by the exchange specialists, market makers or other participants that trade the Shares. There may be times when the market price and the NAV vary significantly. This means that Shares may trade at a discount to NAV.

 

○In times of market stress, market makers may step away from their role market making in the Shares and in executing trades, which can lead to differences between the market value of the Shares and the Fund’s NAV.

 

○The market price of the Shares may deviate from the Fund’s NAV, particularly during times of market stress, with the result that investors may pay significantly more or significantly less for the Shares than the Fund’s NAV, which is reflected in the bid and ask price for the Shares or in the closing price.

 

○In stressed market conditions, the market for the Shares may become less liquid in response to the deteriorating liquidity of the Fund’s portfolio. This adverse effect on the liquidity of the Shares may, in turn, lead to differences between the market value of the Shares and the Fund’s NAV.

 

NEOS Ethereum High Income ETF | Authorized Participant Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]
●Authorized Participant Risk. Only an Authorized Participant may engage in creation or redemption transactions directly with the Fund. The Fund has a limited number of institutions that may act as an Authorized Participant on an agency basis (i.e., on behalf of other market participants). To the extent that Authorized Participants exit the business or are unable to proceed with creation or redemption orders with respect to the Fund and no other Authorized Participant is able to step forward to create or redeem Creation Units, Fund shares may be more likely to trade at a premium or discount to net asset value and possibly face trading halts or delisting. Authorized Participant concentration risk may be heightened for securities or instruments that have lower trading volumes.

 

Additionally, purchases and redemptions of creation units primarily with cash rather than through in-kind delivery of portfolio securities may cause the Fund to incur certain costs, including brokerage costs or taxable gains or losses that it might not have incurred if it made a redemption in-kind, and therefore decrease the Fund’s NAV to the extent not offset by a transaction fee payable by an AP.

 

NEOS Ethereum High Income ETF | Market and Geopolitical Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Market and Geopolitical Risk. The increasing interconnectivity between global economies and financial markets increases the likelihood that events or conditions in one region or financial market may adversely impact issuers in a different country, region or financial market. Securities in the Fund’s portfolio may underperform due to inflation (or expectations for inflation), interest rates, global demand for particular products or resources, natural disasters, climate change and climate-related events, pandemics, epidemics, terrorism, international conflicts, regulatory events and governmental or quasi-governmental actions. The occurrence of global events similar to those in recent years may result in market volatility and may have long term effects on financial markets worldwide.

 

NEOS Ethereum High Income ETF | Options Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Options Risk. Buying and selling (writing) options are speculative activities and entail greater than ordinary investment risks. Options enable the Fund to purchase exposure that is significantly greater than the premium paid. Consequently, the value of such options can be volatile, and a small investment in options can have a large impact on the performance of the Fund. The Fund risks losing all or part of the cash paid (premiums) for purchasing options. Even a small decline in the value of a reference asset underlying call options or a small increase in the value of a reference asset underlying put options can result in the entire investment in such options being lost. The Fund’s options also may fail to track the performance of their underlying reference asset, which may limit the effectiveness of the Fund’s strategy. The potential loss from written options can exceed the Fund’s initial investment in such options and could be unlimited.

 

NEOS Ethereum High Income ETF | Tax Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Tax Risk. The Fund invests in derivatives. The federal income tax treatment of a derivative may not be as favorable as a direct investment in an underlying asset. Derivatives may produce taxable income and taxable realized gain. Derivatives may adversely affect the timing, character and amount of income the Fund realizes from its investments. As a result, a larger portion of the Fund’s distributions may be treated as ordinary income rather than as capital gains. In addition, certain derivatives are subject to mark-to-market or straddle provisions of the Internal Revenue Code. If such provisions are applicable, there could be an increase (or decrease) in the amount of taxable dividends paid by the Fund. The use of derivatives, such as call options, may cause the Fund to realize higher amounts of short-term capital gains or otherwise affect the Fund’s ability to pay out dividends subject to preferential rates or the dividend deduction, thereby increasing the amount of taxes payable by some shareholders. The writing of call options by the Fund may significantly reduce or eliminate the ability to make distributions eligible to be treated as qualified dividend income or as eligible for the dividends received deduction for corporate shareholders. From time to time, a portion of a distribution by the Fund may consist of a return of capital (i.e., from your original investment) and not a return of net profit.

 

To qualify as a regulated investment company (“RIC”), the Fund must meet certain requirements concerning the source of its income. The Fund’s investment in the Subsidiary is intended to provide exposure to Ether in a manner that is consistent with the “qualifying income” requirement applicable to RICs. The Internal Revenue Service (“IRS”) has ceased issuing private letter rulings regarding whether the use of subsidiaries by investment companies to invest in certain instruments constitutes qualifying income. If the IRS determines that this source of income is not “qualifying income,” the Fund may cease to qualify as a RIC because the Fund has not received a private letter ruling and is not able to rely on private letter rulings issued to other taxpayers. Failure to qualify as a RIC could subject the Fund to adverse tax consequences, including a federal income tax on its net income at regular corporate rates, as well as a tax to shareholders on such income when distributed as an ordinary dividend.

 

Based on the principles underlying private letter rulings previously issued to other taxpayers, the Fund intends to treat its income from the Subsidiary as qualifying income without any such ruling from the IRS. The tax treatment of the Fund’s investment in the Subsidiary may be adversely affected by future legislation, court decisions, Treasury Regulations and/or guidance issued by the IRS that could affect whether income derived from such investments is “qualifying income” under Subchapter M of the Internal Revenue Code, or otherwise affect the character, timing and/or amount of the Fund’s taxable income or any gains or distributions made by the Fund.

 

NEOS Ethereum High Income ETF | Valuation Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Valuation Risk. The price the Fund could receive upon the sale of a security or other asset may differ from the Fund’s valuation of the security or other asset, particularly for securities or other assets that trade in low volume or volatile markets or that are valued using a fair value methodology. In addition, the value of the securities or other assets in the Fund’s portfolio may change on days or during time periods when shareholders will not be able to purchase or sell the Fund’s shares. Authorized Participants who purchase or redeem Fund shares on days when the Fund is holding fair-valued securities may receive fewer or more shares, or lower or higher redemption proceeds, than they would have received had the Fund not fair-valued securities or used a different valuation methodology. The Fund’s ability to value investments may be impacted by technological issues or errors by pricing services or other third- party service providers.

 

NEOS Ethereum High Income ETF | Large Shareholder and Large-Scale Redemption Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Large Shareholder and Large-Scale Redemption Risk. Certain shareholders, including an Authorized Participant, a third-party investor, the Fund’s adviser or an affiliate of the Fund’s adviser, a market maker, or another entity, may from time to time own or manage a substantial amount of Fund shares, or may invest in the Fund and hold its investment for a limited period of time. There can be no assurance that any large shareholder or large group of shareholders would not redeem their investment. Redemptions of a large number of Fund shares could require the Fund to dispose of assets to meet the redemption requests, which can accelerate the realization of taxable income and/or capital gains and cause the Fund to make taxable distributions to its shareholders earlier than the Fund otherwise would have. In addition, under certain circumstances, non-redeeming shareholders may be treated as receiving a disproportionately large taxable distribution during or with respect to such year.

U.S. Government Securities Risk. U.S. Treasury obligations are backed by the “full faith and credit” of the U.S. government and generally have negligible credit risk. Securities issued or guaranteed by federal agencies or authorities and U.S. government-sponsored instrumentalities or enterprises may or may not be backed by the full faith and credit of the U.S. government.

 

NEOS Ethereum High Income ETF | FLEX Options Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

FLEX Options Risk. Trading FLEX Options involves risks different from, or possibly greater than, the risks associated with investing directly in securities. The Fund may experience losses from specific FLEX Option positions and certain FLEX Option positions may expire worthless. The FLEX Options are listed and trade on an exchange; however, no one can guarantee that a liquid secondary trading market will exist for the FLEX Options. In the event that trading in the FLEX Options is limited or absent, the value of the Fund’s FLEX Options may decrease. In a less liquid market for the FLEX Options, liquidating the FLEX Options may require the payment of a premium (for written FLEX Options) or acceptance of a discounted price (for purchased FLEX Options) and may take longer to complete. A less liquid trading market may adversely impact the value of the FLEX Options and Fund shares and result in the Fund being unable to achieve its investment objective. Less liquidity in the trading of the Fund’s FLEX Options could have an impact on the prices paid or received by the Fund for the FLEX Options in connection with creations and redemptions of the Fund’s shares. Depending on the nature of this impact to pricing, the Fund may be forced to pay more for redemptions (or receive less for creations) than the price at which it currently values the FLEX Options. Such overpayment or under collection could reduce the Fund’s ability to achieve its investment objective. Additionally, in a less liquid market for the FLEX Options, the liquidation of a large number of options may more significantly impact the price. A less liquid trading market may adversely impact the value of the FLEX Options and the value of your investment. The trading in FLEX Options may be less deep and liquid than the market for certain other exchange-traded options, non-customized options or other securities.

 

NEOS Ethereum High Income ETF | Rolling Options Contract Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Rolling Options Contract Risk. The Fund’s investments in options are subject to risks related to rolling. Rolling occurs when the Fund closes out of an options contract as it nears its expiration and replaces it with a contract that has a later expiration. The Fund does not intend to hold options through expiration, but instead intends to “roll” its positions. When the market for these options is such that the prices are higher in the more distant delivery months than in the nearer delivery months, the sale during the course of the “rolling process” of the more nearby contract would take place at a price that is lower than the price of the more distant contract. This pattern of higher option prices for longer expiration contracts is often referred to as “contango.” Alternatively, when the market for options contracts is such that the prices are higher in the nearer months than in the more distant months, the sale during the course of the “rolling process” of the more nearby contract would take place at a price that is higher than the price of the more distant contract. This pattern of higher options prices for shorter expiration options contracts is referred to as “backwardation.” Extended periods of contango or backwardation have occurred in the past and can in the future cause significant losses for the Fund.

 

NEOS Ethereum High Income ETF | Wholly Owned Subsidiary Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Wholly-Owned Subsidiary Risk. Changes in the laws of the United States and/or the Cayman Islands, under which the Fund and the Subsidiary, respectively, are organized, could result in the inability of the Fund and/or Subsidiary to operate as described in this Prospectus and could negatively affect the Fund and its shareholders. The Subsidiary is not registered under the 1940 Act and, unless otherwise noted in this Prospectus, is not subject to all of the investor protections of the 1940 Act, such as limits on leverage when viewed in isolation from the Fund. Because the Fund wholly owns and controls the Subsidiary, and is overseen by the Adviser, it is unlikely that the Subsidiary will take action contrary to the interests of the Fund or its shareholders.

 

NEOS Ethereum High Income ETF | Taxation Risk [Member]  
Prospectus [Line Items]

Taxation Risk. By investing in certain Spot Ether ETPs indirectly through the Subsidiary, the Fund will obtain exposure to these investments within the federal tax requirements that apply to the Fund. The Subsidiary is classified as a controlled foreign corporation for U.S. tax purposes. Because the Subsidiary is a controlled foreign corporation any income received from its investments will be passed through to the Fund as ordinary income. 

 

NEOS Ethereum High Income ETF | New Fund Risk [Member]

New Fund Risk. If the Fund does not grow large in size once it commences trading, it will be at greater risk than larger funds of wider bid-ask spreads for its shares, trading at a greater premium or discount to NAV, liquidation and/or a stop to trading. Any resulting liquidation of the Fund could cause the Fund to incur elevated transaction costs for the Fund and negative tax consequences for its shareholders.

Absence of Prior Active Market Risk. While the Fund’s Shares are listed on Cboe BZX Exchange, Inc. (the “Exchange”), there can be no assurance that an active trading market for Shares will develop or be maintained. The Fund’s distributor does not maintain a secondary market in Shares.

 

NEOS Ethereum High Income ETF | Portfolio Turnover Risk [Member]

Portfolio Turnover Risk. Due to its investment strategy, the Fund may buy and sell securities, and option contracts, frequently. This may result in higher transaction costs and additional capital gains tax liabilities, which may affect the Fund’s performance.

 

NEOS Ethereum High Income ETF | Spot Ether ETP Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Spot Ether ETP Risk. The value of a Spot Ether ETP security may be more volatile than the market as a whole and may perform differently from the value of the market as a whole. It is possible that Spot Ether ETP issuer-specific attributes may cause an investment held by the Fund in such Spot Ether ETP to be more volatile than the market generally.

 

Many of the risks associated with Spot Ether ETP securities are the same as the risks of owning Ether directly. See Ether Risk.

 

Spot Ether ETPs have been in existence a relatively short period of time with a short trading history. Trading in Spot Ether ETP shares is a recent development. If a Spot Ether ETP’s creation and redemption process is interrupted or experiences difficulties, the arbitrage mechanism utilized by authorized participants to reduce the differences between the Spot Ether ETP’s market price and net asset value may not work as intended and the market price of the Ether ETP shares may fall or otherwise diverge from the Spot Ether ETP’s net asset value, which may result in the Spot Ether ETP’s shares trading at an increased premium or discount. A Spot Ether ETP may suspend the issuance of shares at any time which will impact the price of shares of a Spot Ether ETP, resulting in significant difference (premium/discount) between the Spot Ether ETP’s market price and its net asset value. Additionally, the Fund may be unable to transact in the shares of the Spot Ether ETP at an acceptable price and therefore the Fund may be unable to achieve its investment objective.

 

Cybersecurity or other threats to a Spot Ether ETP’s account at its custodian could result in the halting of the Spot Ether ETP’s operations and a loss of the Spot Ether ETP’s assets, which could result in a reduction of the value of the shares of the Spot Ether ETP and the Fund.

 

Spot Ether ETPs are subject to custodian risk including if the custodian fails to provide services as required or terminates the custodian agreement.

 

Spot Ether ETPs determine the spot price of Ether and calculate their net asset values in reliance on composite indexes and other pricing sources. These indexes have a limited operating history. Thus, there is a risk that the price reported by the indexes could fail to track the global Ether price, which would adversely affect the value of a Spot Ether ETP’s shares and the Fund. The value of a Spot Ether ETP as represented by an index or other pricing source used by a Spot Ether ETP could be adversely affected by trading activity on digital asset platforms.

 

Spot Ether ETPs are not registered as an investment company subject to the 1940 Act. Accordingly, investors in Spot Ether ETPs do not have the protections expressly provided by that statute, including: provisions preventing Spot Ether ETP insiders from managing a Spot Ether ETP to their benefit and to the detriment of shareholders; provisions preventing a Spot Ether ETP from issuing securities having inequitable or discriminatory provisions; provisions preventing management by irresponsible persons; provisions preventing the use of unsound or misleading methods of computing Spot Ether ETP earnings and asset value; provisions prohibiting suspension of redemptions (except under limited circumstances); provisions limiting fund leverage; provisions imposing a fiduciary duty on fund managers with respect to receipt of compensation for services; and provisions preventing changes in a Spot Ether ETP’s character without the consent of shareholders. Because the Fund invests in one or more Spot Ether ETPs indirectly through the Subsidiary, the Fund’s investments are expected to be subject to loss as a result of these risks.

 

Spot Ether ETPs are subject to management fees and other expenses, and the Fund’s investments in Spot Ether ETPs will create higher costs for the Fund compared to the costs of the Fund owning Ether directly.

 

NEOS Ethereum High Income ETF | Ether Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Ether Risk. The value of the Fund’s investment in Spot Ether ETPs and options on Ether-related instruments is subject to fluctuations in the value of Ether. Ether is a relatively new innovation and the market for Ether is subject to rapid price swings, changes and uncertainty. The further development of the Ether Network and the acceptance and use of Ether are subject to a variety of factors that are difficult to evaluate. The value of Ether has been, and may continue to be, substantially dependent on speculation, such that trading and investing in these assets generally may not be based on fundamental analysis. The slowing, stopping or reversing of the development of the Ether Network or the acceptance of Ether may adversely affect the price of Ether. Ether is subject to the risk of fraud, theft, manipulation or security failures, operational or other problems that impact ether trading venues. Additionally, if one or a coordinated group of validators were to gain control of 33% or more of staked Ether, they would have the ability to execute extensive attacks, manipulate transactions and fraudulently obtain ether. If such a validator or group of validators were to gain control of one-third of staked ether, they could halt payments. A significant portion of ether is held by a small number of holders sometimes referred to as “whales”. Transactions by these holders may influence the price of ether and these holders may have the ability to manipulate the price of Ether.

 

Unlike the exchanges for more traditional assets, such as equity securities and futures contracts, Ether and the digital asset trading venues on which it trades are largely unregulated and highly fragmented and digital asset trading venues may be operating out of compliance with regulations. As a result of the lack of regulation, individuals or groups may engage in fraud or market manipulation (including using social media to promote Ether in a way that artificially increases the price of Ether). Investors may be more exposed to the risk of theft, fraud and market manipulation than when investing in more traditional asset classes. Over the past several years, a number of digital asset trading venues have been closed due to fraud, failure or security breaches. Investors in Ether may have little or no recourse should such theft, fraud or manipulation occur and could suffer significant losses.

 

Legal or regulatory changes may negatively impact the operation of the Ethereum Network or restrict the use of Ether. The digital asset trading venues upon which Ether trades have been subject to enforcement actions by regulatory authorities, and the Ether Futures ETFs and Spot Ether ETPs may be negatively impacted by such regulatory enforcement actions. Any such actions could significantly reduce the number of venues upon which Ether trades and could negatively impact the Ether futures contracts held by the Ether Futures ETFs that reference the price of Ether or the Ether held by the Spot Ether ETPs.

 

In addition, digital asset trading venues, Ether validators, and other participants may have significant exposure to other digital assets. Instability in the price, availability or legal or regulatory status of those instruments may adversely impact the operation of the digital asset trading venues and the Ethereum Network. The realization of any of these risks could result in a decline in the acceptance of Ether and consequently a reduction in the value of Ether, Ether futures contracts, and shares of the Spot Ether ETPs and options on Ether-related instruments held by the Fund. Such occurrences could also impair the Ether-related instruments’ ability to meet their investment objective pursuant to their respective investment strategy.

 

Lastly, the creation of a “fork” (as described above) or a substantial giveaway of ether (sometimes referred to as an “air drop”) may result in significant and unexpected declines in the value of ether, Ether-related instruments, and the Fund. A fork may be intentional, such as the ‘Merge.’ The ‘Merge’ refers to protocol changes altering the method by which transactions are validated.

 

The realization of any of these risks could result in a decline in the acceptance of Ether and consequently a reduction in the value of Ether, Spot Ether ETPs, options on Ether-related instruments, and the Fund.

 

NEOS Ethereum High Income ETF | Ether Tax Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Ether Tax Risk. By investing in Spot Ether ETPs indirectly through the Subsidiary, the Fund will obtain exposure to the crypto asset Ether within the federal tax requirements that apply to the Fund. However, because the Subsidiary is a controlled foreign corporation organized under the laws of the Cayman Islands, any income received by the Fund from its investments in the Subsidiary will be passed through to the Fund as ordinary income, which may be taxed at less favorable rates than capital gains.

 

A direct investment by the Fund in a Spot Ether ETP will generally be treated as a direct investment in Ether for U.S. federal income tax purposes. In order to qualify for the special tax treatment accorded a regulated investment company (“RIC”) and its shareholders, Subchapter M of the Internal Revenue Code of 1986, as amended (the “Code”) requires, among other things, that at least 90% of the Fund’s income be “qualifying income.” Although the income from a direct investment in Spot Ether ETPs is not treated as qualifying income, the income generated from the Fund’s options on the Spot Ether ETPs or indices that use one or more Spot Ether ETPs as the reference asset is considered qualifying income because the option itself is the relevant security for purposes of Section 851(b)(2)) of the Code.

 

To the extent the IRS disagrees with this view, then the Fund may fail to qualify as a RIC under the Code. If, in any year, the Fund fails to qualify as a RIC and was ineligible to or was not able to cure such failure, the Fund would be taxed in the same manner as an ordinary corporation and subject to U.S. federal income tax on all its income at the fund level. The resulting taxes could substantially reduce the Fund’s net assets and the amount of income available for distribution. In addition, in order to requalify for taxation as a RIC, the Fund could be required to recognize unrealized gains, pay substantial taxes and interest, and make certain distributions. See “Options Risk” and “Derivatives Risk” below for additional risks regarding the Fund’s options strategy.

 

NEOS Ethereum High Income ETF | Ether Futures ETFs Risks [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Ether Futures ETFs Risks. The Ether Futures ETFs do not invest directly in Ether. Instead, the Ether Futures ETFs obtain indirect exposure to Ether by investing in Ether futures. The market for derivatives linked to Ether may be less developed, and potentially less liquid and more volatile, than more established markets. While these markets have grown substantially since Ether derivatives commenced trading, there can be no assurance that this growth will continue. The price for Ether futures and options is based on a number of factors, including the supply of and the demand for these derivatives. Market conditions and expectations, position limits, accountability levels, collateral requirements, availability of counterparties, and other factors each can impact the supply of and demand for these derivatives. Additionally, due to the high margin requirements that are unique to Ether futures contracts, the Ether Futures ETFs may experience difficulty maintaining the desired level of exposure to Ether solely through futures contracts. If an Ether Futures ETF is unable to achieve such exposure it may not be able to meet its investment objective and the Ether Futures ETF’s returns may be different or lower than expected. Additionally, collateral requirements may require the Ether Futures ETFs to liquidate their positions, potentially incurring losses and expenses, when it otherwise would not do so. Investing in derivatives like Ether futures may be considered aggressive and may expose the Ether Futures ETFs to significant risks. These risks include counterparty risk and liquidity risk.

 

NEOS Ethereum High Income ETF | Custody Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Custody Risk. Security breaches, computer malware and computer hacking attacks have been a prevalent concern in relation to digital assets. The Ether held by the Spot Ether ETPs’ custodian will likely be an appealing target to hackers or malware distributors seeking to destroy, damage or steal the Spot Ether ETPs’ ether. To the extent that the Spot Ether ETPs and their service providers are unable to identify and mitigate or stop new security threats or otherwise adapt to technological changes in the digital asset industry, a Spot Ether ETP’s ether may be subject to theft, loss, destruction or other attack. The Spot Ether ETPs have put security procedures in place to prevent such theft, loss or destruction, including but not limited to, offline storage, or cold storage, multiple encrypted private key “shards”, and other measures. Nevertheless, the security procedures cannot guarantee the prevention of any loss due to a security breach, software defect or act of God that may be borne by the Spot Ether ETPs and the security procedures may not protect against all errors, software flaws or other vulnerabilities in an Spot Ether ETP’s technical infrastructure, which could result in theft, loss or damage of its assets. The Spot Ether ETPs do not control the operations of their service providers or their implementation of such security procedures and there can be no assurance that such security procedures will actually work as designed or prove to be successful in safeguarding a Spot Ether ETP’s assets against all possible sources of theft, loss or damage. Assets not held in cold storage, such as assets held in a trading account, may be more vulnerable to security breach, hacking or loss than assets held in cold storage. Furthermore, assets held in a trading account are held on an omnibus, rather than segregated basis, which creates greater risk of loss. The security procedures and operational infrastructure may be breached due to the actions of outside parties, error or malfeasance of an employee of an Spot Ether ETP’s service providers, and, as a result, an unauthorized party may obtain access to the Spot Ether ETP’s account at the custodian where its ether is held, the relevant private keys (and therefore ether) or other data or property of a Spot Ether ETP. Additionally, outside parties may attempt to fraudulently induce employees of a Spot Ether ETP or its service providers to disclose sensitive information in order to gain access to a Spot Ether ETP’s infrastructure. As the techniques used to obtain unauthorized access, disable or degrade service, or sabotage systems change frequently, or may be designed to remain dormant until a predetermined event and often are not recognized until launched against a target, a Spot Ether ETP and its service providers may be unable to anticipate these techniques or implement adequate preventative measures.

Derivatives Risk. Options are a derivative investment. The use of derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities and other traditional investments. These risks include (i) the risk that the counterparty to a derivative transaction may not fulfil its contractual obligations; (ii) risk of mispricing or improper valuation; and (iii) the risk that changes in the value of the derivative may not correlate perfectly with the underlying asset, rate or index. Derivative prices are highly volatile and may fluctuate substantially during a short period of time. Such prices are influenced by numerous factors that affect the markets, including, but not limited to: changing supply and demand relationships; government programs and policies; national and international political and economic events, changes in interest rates, inflation and deflation and changes in supply and demand relationships.

Exchange Traded Funds (“ETFs”) Risk. The Fund is structured as an ETF. As a result, the Fund is subject to special risks, including:

 

NEOS Long/Short Equity Income ETF | Not Individually Redeemable [Member]  
Prospectus [Line Items]  
Risk [Text Block]
  ● Not Individually Redeemable. The Fund’s shares (“Shares”) are not redeemable by retail investors and may be redeemed only by Authorized Participants at net asset value (“NAV”) and only in Creation Units. A retail investor generally incurs brokerage costs when selling shares.
NEOS Long/Short Equity Income ETF | Trading Issues [Member]  
Prospectus [Line Items]  
Risk [Text Block]
  ● Trading Issues. Trading in Shares on the Exchange may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in Shares inadvisable, such as extraordinary market volatility. There can be no assurance that Shares will continue to meet the listing requirements of the Exchange which may result in the Shares being delisted. An active trading market for the Shares may not be developed or maintained. If the Shares are traded outside a collateralized settlement system, the number of financial institutions that can act as Authorized Participants that can post collateral on an agency basis is limited, which may limit the market for the Shares.
NEOS Long/Short Equity Income ETF | Market Price Variance Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]
  ● Market Price Variance Risk. The market prices of Shares will fluctuate in response to changes in NAV and supply and demand for Shares and will include a “bid-ask spread” charged by the exchange specialists, market makers or other participants that trade the Shares. There may be times when the market price and the NAV vary significantly. This means that Shares may trade at a discount to NAV.
  ○ In times of market stress, market makers may step away from their role market making in the Shares and in executing trades, which can lead to differences between the market value of the Shares and the Fund’s NAV.
  ○ The market price of the Shares may deviate from the Fund’s NAV, particularly during times of market stress, with the result that investors may pay significantly more or significantly less for the Shares than the Fund’s NAV, which is reflected in the bid and ask price for the Shares or in the closing price.
  ○ In stressed market conditions, the market for the Shares may become less liquid in response to the deteriorating liquidity of the Fund’s portfolio. This adverse effect on the liquidity of the Shares may, in turn, lead to differences between the market value of the Shares and the Fund’s NAV.
NEOS Long/Short Equity Income ETF | Authorized Participant Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]
  ● Authorized Participant Risk. Only an Authorized Participant may engage in creation or redemption transactions directly with the Fund. The Fund has a limited number of institutions that may act as an Authorized Participant on an agency basis (i.e., on behalf of other market participants). To the extent that Authorized Participants exit the business or are unable to proceed with creation or redemption orders with respect to the Fund and no other Authorized Participant is able to step forward to create or redeem Creation Units, Fund shares may be more likely to trade at a premium or discount to net asset value and possibly face trading halts or delisting. Authorized Participant concentration risk may be heightened for securities or instruments that have lower trading volumes.
Additionally, purchases and redemptions of creation units primarily with cash rather than through in-kind delivery of portfolio securities may cause the Fund to incur certain costs, including brokerage costs or taxable gains or losses that it might not have incurred if it made a redemption in-kind, and therefore decrease the Fund’s NAV to the extent not offset by a transaction fee payable by an AP.

 

NEOS Long/Short Equity Income ETF | Issuer Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Issuer Risk. Changes in the financial condition or credit rating of an issuer or counterparty, changes in specific economic or political conditions that affect a particular type of security or issuer, and changes in general economic or political conditions can affect the value of a security or instrument value. The values of securities of smaller, less well-known issuers can be more volatile than those of larger issuers. Issuer-specific events can have a negative impact on the value of the Fund.

 

NEOS Long/Short Equity Income ETF | Market and Geopolitical Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Market and Geopolitical Risk. The increasing interconnectivity between global economies and financial markets increases the likelihood that events or conditions in one region or financial market may adversely impact issuers in a different country, region or financial market. Securities in the Fund’s portfolio may underperform due to inflation (or expectations for inflation), interest rates, global demand for particular products or resources, natural disasters, climate change and climate-related events, pandemics, epidemics, terrorism, international conflicts, regulatory events and governmental or quasi-governmental actions. The occurrence of global events similar to those in recent years may result in market volatility and may have long term effects on financial markets worldwide.

 

 

NEOS Long/Short Equity Income ETF | Options Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Options Risk. Buying and selling (writing) options are speculative activities and entail greater than ordinary investment risks. Options enable the Fund to purchase exposure that is significantly greater than the premium paid. Consequently, the value of such options can be volatile, and a small investment in options can have a large impact on the performance of the Fund. The Fund risks losing all or part of the cash paid (premiums) for purchasing options. Even a small decline in the value of a reference asset underlying call options or a small increase in the value of a reference asset underlying put options can result in the entire investment in such options being lost. The Fund’s options also may fail to track the performance of their underlying reference asset, which may limit the effectiveness of the Fund’s strategy. The potential loss from written options can exceed the Fund’s initial investment in such options and could be unlimited.

 

NEOS Long/Short Equity Income ETF | Tax Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Tax Risk. The Fund invests in derivatives. The federal income tax treatment of a derivative may not be as favorable as a direct investment in an underlying asset. Derivatives may produce taxable income and taxable realized gain. Derivatives may adversely affect the timing, character and amount of income the Fund realizes from its investments. As a result, a larger portion of the Fund’s distributions may be treated as ordinary income rather than as capital gains. In addition, certain derivatives are subject to mark-to-market or straddle provisions of the Internal Revenue Code of 1986, as amended (the “Internal Revenue Code”). If such provisions are applicable, there could be an increase (or decrease) in the amount of taxable dividends paid by the Fund.

 

NEOS Long/Short Equity Income ETF | Valuation Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Valuation Risk. The price the Fund could receive upon the sale of a security or other asset may differ from the Fund’s valuation of the security or other asset, particularly for securities or other assets that trade in low volume or volatile markets or that are valued using a fair value methodology as a result of trade suspensions or for other reasons. In addition, the value of the securities or other assets in the Fund’s portfolio may change on days or during time periods when shareholders will not be able to purchase or sell the Fund’s shares. The Fund’s ability to value investments may be impacted by technological issues or errors by pricing services or other third- party service providers.

 

NEOS Long/Short Equity Income ETF | Cybersecurity Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Cybersecurity Risk. The computer systems, networks and devices used by the Fund and its service providers to carry out routine business operations employ a variety of protections designed to limit damage or interruption from computer viruses, network failures, computer and telecommunication failures, infiltration by unauthorized persons and security breaches. Despite the various protections utilized by the Fund and its service providers, systems, networks, or devices potentially can be breached. The Fund and its shareholders could be negatively impacted as a result of a cybersecurity breach.

 

NEOS Long/Short Equity Income ETF | Equity Securities Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Equity Securities Risk. The net asset value of the Fund will fluctuate based on changes in the value of the equity securities held by the Fund. The value of a security may decline for a number of reasons that may directly relate to the issuer as well as due to general industry or market conditions. Common stock is subordinated to preferred securities and debt in a company’s capital structure. Common stock has the lowest priority, and the greatest risk, with respect to dividends and any liquidation payments in the event of an issuer’s bankruptcy. Equity prices can fall rapidly in response to developments affecting a specific company or industry, or to changing economic, political or market conditions.

 

NEOS Long/Short Equity Income ETF | New Fund Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

New Fund Risk. The Fund is a new fund, with limited operating history, which may result in additional risks for investors in the Fund. There can be no assurance that the Fund will grow to or maintain an economically viable size, in which case the Board of Trustees may determine to liquidate the Fund. While shareholder interests will be the paramount consideration, the timing of any liquidation may not be favorable to certain individual shareholders.

 

NEOS Long/Short Equity Income ETF | Absence of Prior Active Market Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Absence of Prior Active Market Risk. While the Fund’s Shares are listed on Cboe BZX Exchange, Inc. (the “Exchange”), there can be no assurance that an active trading market for Shares will develop or be maintained. The Fund’s distributor does not maintain a secondary market in Shares.

 

NEOS Long/Short Equity Income ETF | Portfolio Turnover Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Portfolio Turnover Risk. Due to its investment strategy, the Fund may buy and sell securities frequently. This may result in higher transaction costs and additional capital gains tax liabilities, which may affect the Fund’s performance.

 

NEOS Long/Short Equity Income ETF | Short Selling Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Short Selling Risk. If a security sold short, the Fund may have to cover its short position at a higher price than the short sale price, resulting in a loss. Because losses on short sales arise from increases in the value of the security sold short, such losses are theoretically unlimited. The Fund may not be able to successfully implement its short sale strategy due to limited availability of desired securities or for other reasons.

 

NEOS Long/Short Equity Income ETF | Model Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Model Risk. Like all quantitative analysis, the investment model used by the Adviser carries a risk that the used might be based on one or more incorrect assumptions, including as a result of the Adviser’s incorrect assumptions and determinations with respect to the quality and/or relevance of the inputs and relationship between the inputs. If the model or data used by the Adviser are incorrect or incomplete, any decision the Adviser makes in reliance thereon may lead the Fund to include or exclude certain securities in its portfolio that would have otherwise been included or excluded if the model or data was correct or complete. Rapidly changing and unforeseen market dynamics could lead to a decrease in the short-term effectiveness of the model and could have an adverse effect on the securities selected for the Fund. No assurance can be given that the Fund will be successful under all or any market conditions.
