ACTIVE MANAGEMENT RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

ACTIVE MANAGEMENT RISK. The Fund is actively-managed and its performance reflects investment decisions that the Adviser makes for the Fund. In managing the Fund’s investment portfolio, the portfolio managers will apply investment techniques and risk analyses, including through the use of technology, automated processes, algorithms, or other management systems, that may not operate as intended or produce the desired result. Such judgments about the Fund’s investments may prove to be incorrect. If the investments selected and the strategies employed by the Fund fail to produce the intended results, the Fund could underperform as compared to other funds with similar investment objectives and/or strategies, or could have negative returns.

 

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, Fund 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.

 

CASH TRANSACTIONS RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

CASH TRANSACTIONS RISK. The Fund currently expects to effect a significant portion of its creations and redemptions for cash, rather than in-kind securities. Paying redemption proceeds in cash rather than through in-kind delivery of portfolio securities may require the Fund to dispose of or sell portfolio securities or other assets at an inopportune time to obtain the cash needed to meet redemption orders. This may cause the Fund to sell a security and recognize a capital gain or loss that might not have been incurred if it had made a redemption in-kind. As a result, the Fund may pay out higher or lower annual capital gains distributions than ETFs that redeem in-kind. The use of cash creations and redemptions may also cause Fund Shares to trade in the market at greater bid-ask spreads or greater premiums or discounts to the Fund’s NAV. Furthermore, the Fund may not be able to execute cash transactions for creation and redemption purposes at the same price used to determine the Fund’s NAV. To the extent that the maximum additional charge for creation or redemption transactions is insufficient to cover the execution shortfall, the Fund’s performance could be negatively impacted.

 

CLEARING MEMBER DEFAULT RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

CLEARING MEMBER DEFAULT RISK. Transactions in some types of derivatives, including the options held by the Fund, are required to be centrally cleared (“cleared derivatives”). In a transaction involving cleared derivatives, the Fund’s counterparty is a clearinghouse, such as the OCC, rather than a bank or broker. Since the Fund is not a member of clearinghouses, and only members of a clearinghouse (“clearing members”) can participate directly in the clearinghouse, the Fund will hold cleared derivatives through accounts at clearing members. With regard to its cleared derivatives positions, the Fund will make payments (including margin payments) to, and receive payments from, a clearinghouse through their accounts at clearing members. Customer funds held at a clearing organization in connection with any options contracts are held in a commingled omnibus account and are not identified to the name of the clearing member’s individual customers. As a result, assets deposited by the Fund with any clearing member as margin for its options position may, in certain circumstances, be used to satisfy losses of other clients of the Fund’s clearing member. In addition, although clearing members guarantee performance of their clients’ obligations to the clearinghouse, there is a risk that the assets of the Fund might not be fully protected in the event of the clearing member’s bankruptcy. The Fund is also subject to the risk that a limited number of clearing members are willing to transact on the Fund’s behalf, which heightens the risks associated with a clearing member’s default. If a clearing member defaults, the Fund could lose some or all of the benefits of a transaction entered into by the Fund with the clearing member. The loss of a clearing member for the Fund to transact with could result in increased transaction costs and other operational issues that could impede the Fund’s ability to implement its investment strategy. If the Fund cannot find a clearing member to transact with on the Fund’s behalf, the Fund may be unable to effectively implement its investment strategy.

 

COSTS OF BUYING AND SELLING FUND SHARES RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

COSTS OF BUYING AND SELLING FUND SHARES RISK. Due to the costs of buying or selling Fund Shares, including brokerage commissions imposed by brokers and bid/ask spreads, frequent trading of Fund Shares may significantly reduce investment results and an investment in Fund Shares may not be advisable for investors who anticipate regularly making small investments.

 

COUNTERPARTY RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

COUNTERPARTY RISK. The Fund is subject to counterparty risk by virtue of its investments in options contracts. Transactions in some types of derivatives, including options, are required to be centrally cleared (cleared derivatives). In a transaction involving cleared derivatives, the Fund’s counterparty is a clearing house rather than a bank or broker. Since the Fund is not a member of clearing houses and only members of a clearing house (clearing members) can participate directly in the clearing house, the Fund will hold cleared derivatives through accounts at clearing members. In cleared derivatives positions, the Fund will make payments (including margin payments) to and receive payments from a clearing house through their accounts at clearing members. Customer funds held at a clearing organization in connection with any options contracts are held in a commingled omnibus account and are not identified to the name of the clearing members’ individual customers. As a result, assets deposited by the Fund with any clearing member as margin for options may, in certain circumstances, be used to satisfy losses of other clients of the Fund’s clearing member. In addition, although clearing members guarantee performance of their clients’ obligations to the clearing house, there is a risk that the assets of the Fund might not be fully protected in the event of the clearing members’ bankruptcy, as the Fund would be limited to recovering only a pro rata share of all available funds segregated on behalf of the clearing members’ customers for the relevant account class. The Fund is also subject to the risk that a limited number of clearing members are willing to transact on the Fund’s behalf, which heightens the risks associated with a clearing members’ default. If a clearing member defaults, the Fund could lose some or all of the benefits of a transaction entered into by the Fund with the clearing member. If the Fund cannot find a clearing member to transact with on the Fund’s behalf, the Fund may be unable to effectively implement its investment strategy.

 

CYBER SECURITY RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Cyber security Risk. The Fund is susceptible to operational risks through breaches in cyber security. A breach in cyber security refers to both intentional and unintentional events that may cause the Fund to lose proprietary information, suffer data corruption or lose operational capacity. Such events could cause the Fund to incur regulatory penalties, reputational damage, additional compliance costs associated with corrective measures and/or financial loss. Cyber security breaches may involve unauthorized access to the Fund’s digital information systems through “hacking” or malicious software coding but may also result from outside attacks such as denial-of-service attacks through efforts to make network services unavailable to intended users. In addition, cyber security breaches of the issuers of securities in which the Fund invests or the Fund’s third-party service providers, such as its administrator, transfer agent, custodian, or sub-adviser, as applicable, can also subject the Fund to many of the same risks associated with direct cyber security breaches. Although the Fund has established risk management systems designed to reduce the risks associated with cyber security, there is no guarantee that such efforts will succeed, especially because the Fund does not directly control the cyber security systems of issuers or third-party service providers.

 

DEBT SECURITIES RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

DEBT SECURITIES RISK. The Fund will invest in various types of debt securities, which may be used for collateral for the Fund’s options contracts and/or swap agreements and may be used to generate additional income. Investments in debt securities subject the holder to the credit risk of the issuer. Credit risk refers to the possibility that the issuer or other obligor of a security will not be able or willing to make payments of interest and principal when due. Generally, the value of debt securities will change inversely with changes in interest rates. To the extent that interest rates rise, certain underlying obligations may be paid off substantially slower than originally anticipated and the value of those securities may fall sharply. During periods of falling interest rates, the income received by the Fund may decline. If the principal on a debt security is prepaid before expected, the prepayments of principal may have to be reinvested in obligations paying interest at lower rates. Debt securities generally do not trade on a securities exchange making them generally less liquid and more difficult to value than common stock.

 

DERIVATIVES RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

DERIVATIVES RISK. Derivatives are financial instruments that derive value from the underlying reference asset or assets, such as stocks, bonds, or funds (including ETFs), interest rates or indexes. The Fund’s investments in derivatives may pose risks in addition to, and greater than, those associated with directly investing in securities or other ordinary investments, including risk related to the market, imperfect correlation with underlying investments or the Fund’s other portfolio holdings, higher price volatility, lack of availability, counterparty risk, liquidity, valuation, and legal restrictions. The use of derivatives is a highly specialized activity that involves investment techniques and risks different from those associated with ordinary portfolio securities transactions. The use of derivatives may result in larger losses or smaller gains than directly investing in securities. When the Fund uses derivatives, there may be imperfect correlation between the value of the underlying instrument and the derivative, which may prevent the Fund from achieving its investment objectives. Because derivatives often require only a limited initial investment, the use of derivatives may expose the Fund to losses in excess of those amounts initially invested. In addition, the Fund’s investments in derivatives are subject to the following risks:

 

OPTIONS CONTRACTS RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

OPTIONS CONTRACTS RISK. The use of options contracts involves investment strategies and risks different from those associated with ordinary portfolio securities transactions. The prices of options are volatile and are influenced by, among other things, actual and anticipated changes in the value of the underlying instrument, including the anticipated volatility, which are affected by fiscal and monetary policies and by national and international political events, changes in the actual or implied volatility or the reference asset, the time remaining until the expiration of the options contract and economic events. For the Fund in particular, the values of the options contracts in which it invests are substantially influenced by the values of the underlying instruments. The Fund may experience substantial downside from specific option positions and certain option positions held by the Fund may expire worthless. The options held by the Fund are exercisable at the strike price on their expiration date. As an option approaches its expiration date, its value typically increasingly moves with the value of the underlying instrument. However, prior to expiry, the value of an option generally does not increase or decrease at the same rate as the underlying instrument. There may at times be an imperfect correlation between the movement in values of options contracts and the underlying instrument, and there may at times not be a liquid secondary market for certain options contracts. The value of the options held by the Fund will be determined based on market quotations or other recognized pricing methods. As the options contracts are exercised or expire the Fund will enter into new options contracts, a practice referred to as rolling.

 

DISTRIBUTION RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

DISTRIBUTION RISK. As part of the Fund’s investment objectives, the Fund seeks to provide current income. There is no assurance that the Fund will make a distribution at any given time. If the Fund does make distributions, the amounts of such distributions will likely vary greatly from one distribution to the next. Additionally, the distributions, if any, may consist of returns of capital, which would decrease the Fund’s NAV and trading price over time. As a result, an investor may suffer significant losses to their investment.

 

DISTRIBUTION TAX RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

DISTRIBUTION TAX RISK. The Fund currently expects to make distributions on a regular basis. While the Fund will normally pay its income as distributions, the Fund’s distributions may exceed the Fund’s income and gains for the Fund’s taxable year. The Fund may be required to reduce its distributions if it has insufficient income. Additionally, there may be times the Fund needs to sell securities when it would not otherwise do so and could cause the distributions from that sale to constitute return of capital. Distributions in excess of the Fund’s current and accumulated earnings and profits will be treated as a return of capital. Return of capital distributions do not represent income or gains generated by the Fund’s investment activities and should not be interpreted by shareholders as such. Distributions in excess of the Fund’s minimum distribution requirements, but not in excess of the Fund’s earnings and profits, will be taxable to Fund shareholders and will not constitute nontaxable returns of capital. A return of capital distribution generally will not be currently taxable but will reduce the shareholder’s cost basis and will result in a higher capital gain or lower capital loss when those Fund shares on which the distribution was received are sold. Once a Fund shareholder’s cost basis is reduced to zero, further distributions (in excess of earnings and profits) will be treated as capital gain, if the Fund shareholder holds shares of the Fund as capital assets. Additionally, any capital returned through distributions will be distributed after payment of Fund fees and expenses. Because the Fund’s distributions may consist of return of capital, the Fund may not be an appropriate investment for investors who do not want their principal investment in the Fund to decrease over time or who do not wish to receive return of capital in a given period. In the event that a shareholder purchases shares of the Fund shortly before a distribution by the Fund, the entire distribution may be taxable to the shareholder even though a portion of the distribution effectively represents a return of the purchase price.

 

DIVIDEND RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

DIVIDEND RISK. There is no guarantee that the issuers of the Fund’s portfolio securities will declare dividends in the future or that, if declared, they will either remain at current levels or increase over time.

 

EQUITY SECURITIES RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

EQUITY SECURITIES RISK. Equity securities are subject to changes in value, and their values may be more volatile than those of other asset classes. Equity securities prices fluctuate for several reasons, including changes in investors’ perceptions of the financial condition of an issuer or the general condition of the relevant equity market, such as market volatility, or when political or economic events affecting an issuer occur. Common stock prices may be particularly sensitive to rising interest rates, as the cost of capital rises and borrowing costs increase. Common stocks generally subject their holders to more risks than preferred stocks and debt securities because common stockholders’ claims are subordinated to those of holders of preferred stocks and debt securities upon the bankruptcy of the issuer.

 

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 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 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.

 

HIGH PORTFOLIO TURNOVER RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

HIGH PORTFOLIO TURNOVER RISK. The Fund may actively and frequently trade all or a significant portion of the Fund’s holdings. A high portfolio turnover rate increases transaction costs, which may increase the Fund’s expenses. Frequent trading may also cause adverse tax consequences for investors in the Fund due to an increase in short-term capital gains.

 

INFLATION RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

INFLATION RISK. Inflation risk is the risk that the value of assets or income from investments will be less in the future as inflation decreases the value of money. As inflation increases, the present value of the Fund’s assets and distributions may decline. This risk is more prevalent with respect to fixed income securities held by the Fund.

 

Interest Rate Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

INTEREST RATE RISK. Interest rate risk is the risk that the value of the debt securities in the Fund’s portfolio will decline because of rising market interest rates. Interest rate risk is generally lower for shorter term debt securities and higher for longer-term debt securities. Duration is a reasonably accurate measure of a debt security’s price sensitivity to changes in interest rates and a common measure of interest rate risk. Duration measures a debt security’s expected life on a present value basis, taking into account the debt security’s yield, interest payments and final maturity. In general, duration represents the expected percentage change in the value of a security for an immediate 1% change in interest rates. For example, the price of a debt security with a three-year duration would be expected to drop by approximately 3% in response to a 1% increase in interest rates. Therefore, prices of debt securities with shorter durations tend to be less sensitive to interest rate changes than debt securities with longer durations. As the value of a debt security changes over time, so will its duration.

 

LARGE CAPITALIZATION COMPANIES RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

LARGE CAPITALIZATION COMPANIES RISK. Large capitalization companies may be less able than smaller capitalization companies to adapt to changing market conditions. Large capitalization companies may be more mature and subject to more limited growth potential compared with smaller capitalization companies. During different market cycles, the performance of large capitalization companies has trailed the overall performance of the broader securities markets.

 

LEVERAGE RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

LEVERAGE RISK. 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. Derivative instruments involve a degree of leverage and as a result, a relatively small price movement in derivative instruments may result in immediate and substantial losses to the Fund.

 

LIQUIDITY RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

LIQUIDITY RISK. Some securities held by the Fund, including options contracts, may be difficult to sell or be illiquid, particularly during times of market turmoil. Markets for securities or financial instruments could be disrupted by a number of events, including, but not limited to, an economic crisis, natural disasters, epidemics/pandemics, new legislation or regulatory changes inside or outside the United States. Illiquid securities may be difficult to value, especially in changing or volatile markets. If the Fund is forced to sell an illiquid security at an unfavorable time or price, the Fund may be adversely impacted. There is no assurance that a security that is deemed liquid when purchased will continue to be liquid. Market illiquidity may cause losses for the Fund.

 

MARKET MAKER RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

market maker Risk. The Fund faces numerous market trading risks, including the potential lack of an active market for Fund Shares due to a limited number of market makers. Decisions by market makers or authorized participants to reduce their role or step away from these activities in times of market stress could inhibit the effectiveness of the arbitrage process in maintaining the relationship between the underlying values of the Fund’s portfolio securities and the Fund Share price. The Fund may rely on a small number of third-party market makers to provide a market for the purchase and sale of Fund Shares. Any trading halt or other problem relating to the trading activity of these market makers could result in a dramatic change in the spread between the Fund’s NAV and the price at which the Fund Shares are trading on the Exchange, which could result in a decrease in value of Fund Shares. This reduced effectiveness could result in Fund Shares trading at a discount to NAV and also in greater than normal intraday bid-ask spreads for Fund Shares.

 

MARKET RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Market Risk. Market risk is the risk that a particular investment, or Fund Shares in general, may fall in value. Securities are subject to market fluctuations caused by real or perceived adverse economic, political, and regulatory factors or market developments, changes in interest rates and perceived trends in securities prices. Fund Shares could decline in value or underperform other investments. In addition, local, regional or global events such as war, acts of terrorism, market manipulation, government defaults, government shutdowns, regulatory actions, political changes, diplomatic developments, the imposition of sanctions and other similar measures, spread of infectious diseases or other public health issues, recessions, natural disasters, or other events could have a significant negative impact on the Fund and its investments. Any of such circumstances could have a materially negative impact on the value of the Fund Shares, the liquidity of an investment, and may result in increased market volatility. During any such events, Fund Shares may trade at increased premiums or discounts to their NAV, the bid/ask spread on Fund Shares may widen and the returns on investment may fluctuate.

 

MONEY MARKET/SHORT-TERM SECURITIES RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

MONEY MARKET/SHORT-TERM SECURITIES RISK. To the extent that the Fund invests in money market or short-term securities, the Fund may be subject to certain risks associated with such investments. An investment in a money market fund or short-term securities is not a bank deposit and is not insured or guaranteed by any bank, the Federal Deposit Insurance Corporation or any other government agency. It is possible for the Fund to lose money by investing in money market funds. A money market fund may not achieve its investment objective. Changes in government regulations may affect the value of an investment in a money market fund.

 

NEW FUND RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

NEW FUND RISK. The Fund is a recently organized management investment company with limited operating history. As a result, prospective investors do not have a track record or history on which to base their investment decisions.

 

OPERATIONAL RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

OPERATIONAL RISK. The Fund is subject to risks arising from various operational factors, including, but not limited to, human error, processing and communication errors, errors of the Fund’s service providers, counterparties or other third-parties, failed or inadequate processes and technology or systems failures. The Fund relies on third-parties for a range of services, including custody. Any delay or failure relating to engaging or maintaining such service providers may affect the Fund’s ability to meet its investment objective. Although the Fund and Adviser seek to reduce these operational risks through controls and procedures, there is no way to completely protect against such risks.

 

PREMIUM/DISCOUNT RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

PREMIUM/DISCOUNT RISK. As with all ETFs, Fund Shares may be bought and sold in the secondary market at market prices. Although it is expected that the market price of Fund Shares will approximate the Fund’s NAV, there may be times when the market price of Fund Shares is more than the NAV intraday (premium) or less than the NAV intraday (discount) due to supply and demand of Fund Shares or during periods of market volatility. This risk is heightened in times of market volatility and volatility in the Fund’s portfolio holdings, periods of steep market declines, and periods when there is limited trading activity for Fund Shares in the secondary market, in which case such premiums or discounts may be significant. If an investor purchases Fund Shares at a time when the market price is at a premium to the NAV of Fund Shares or sells at a time when the market price is at a discount to the NAV of Fund Shares, then the investor may sustain losses that are in addition to any losses caused by a decrease in NAV.

 

PRICE PARTICIPATION RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

PRICE PARTICIPATION RISK. The Fund employs an investment strategy that includes the sale of call options contracts, which limits the degree to which the Fund will participate in increases in value experienced by the Underlying Securities. This means that if the Underlying Securities experience an increase in value above the strike price of the sold call options, the Fund will likely not experience that increase to the same extent and may significantly underperform the Underlying Securities. Additionally, because the Fund is limited in the degree to which it will participate in increases in value experienced by the Underlying Securities, but has full exposure to any decreases in value experienced by the Underlying Securities, the NAV of the Fund may decrease over any given time period. The Fund’s NAV is dependent on the value of each options portfolio, which is based principally upon the performance of the Underlying Securities. The degree of participation in the Underlying Securities’ gains the Fund will experience will depend on prevailing market conditions, especially market volatility, at the time the Fund enters into the sold call options contracts and will vary over time. The value of the options contracts is affected by changes in the value and dividend rates of the Underlying Securities, changes in interest rates, changes in the actual or perceived volatility of the Underlying Securities and the remaining time to the options’ expiration, as well as trading conditions in the options market. As the price of the Underlying Securities changes and time moves towards the options contract’s expiration date, the value of the options contracts, and therefore the Fund’s NAV, will change. However, it is not expected for the Fund’s NAV to directly correlate on a day-to-day basis with the returns of the Underlying Securities. The amount of time remaining until the options contract’s expiration date affects the impact of the potential options contract income on the Fund’s NAV, which may not be in full effect until the expiration date of the Fund’s options contracts. Therefore, while changes in the price of the Underlying Securities will result in changes to the Fund’s NAV, the Fund generally anticipates that the rate of change in the Fund’s NAV will be different than that experienced by the Underlying Securities.

 

SMALL AND/OR MID CAPITALIZATION COMPANIES RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

SMALL AND/OR MID CAPITALIZATION COMPANIES RISK. Small and/or mid capitalization companies may be more vulnerable to adverse general market or economic developments, and their securities may be less liquid and may experience greater price volatility than large capitalization companies as a result of several factors, including limited trading volumes, fewer products or financial resources, management inexperience and less publicly available information. Accordingly, such companies are generally subject to greater market risk than large capitalization companies.

 

SPECIAL TAX RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

SPECIAL TAX RISK. The Fund intends to qualify annually and to elect to be treated as a regulated investment company (“RIC”) under the Code. To qualify for the favorable U.S. federal income tax treatment generally accorded to RICs, the Fund must, among other things: (i) in each taxable year, derive at least 90% of its gross income from dividends, interest, payments with respect to securities loans and gains from the sale or other disposition of stock, securities or foreign currencies or other income derived with respect to its business of investing in such stock, securities or currencies, or net income derived from interests in certain publicly traded partnerships; (ii) diversify its portfolio holdings so that, at the end of each quarter of the taxable year, (a) at least 50% of the market value of the Fund’s assets is represented by cash and cash items (including receivables), U.S. government securities, the securities of other RICs and other securities, with such other securities of any one issuer generally limited for the purposes of this calculation to an amount not greater than 5% of the value of the Fund’s total assets and not greater than 10% of the outstanding voting securities of such issuer, and (b) not more than 25% of the value of its total assets is invested in the securities (other than U.S. government securities or the securities of other RICs) of any one issuer, or two or more issuers which the Fund controls which are engaged in the same, similar or related trades or businesses, or the securities of one or more of certain publicly traded partnerships (the “Diversification Tests”); and (iii) distribute at least 90% of its investment company taxable income (which includes, among other items, dividends, interest and net short-term capital gains in excess of net long-term capital losses) and at least 90% of its net tax-exempt interest income each taxable year. There are certain exceptions for failure to qualify as a RIC if the failure is for reasonable cause, or is de minimis, and certain corrective action is taken and certain tax payments are made by the Fund.

 

The Fund intends to enter into financial instruments on the Underlying Security. At least quarterly, the Fund will need to meet the Diversification Tests to maintain its RIC status. This may require selling some financial instruments referencing the Underlying Security in order to purchase other assets that meet the Diversification Tests. Such sales and purchases could affect the investment return of the Fund and may require the Fund to make distributions that were not otherwise required.

 

If the Fund were to fail to meet the qualifying income test or asset diversification test and fail to qualify as a RIC, it would be taxed in the same manner as an ordinary corporation, and distributions to its shareholders would not be deductible by the Fund in computing its taxable income, which would adversely affect the Fund’s performance.

 

TRADING ISSUES RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

TRADING ISSUES RISK. Although Fund Shares are listed for trading on a national securities exchange, and may be traded on other U.S. exchanges, there can be no assurance that Fund Shares will trade with any volume, or at all, on any stock exchange. In stressed market conditions, the liquidity of Fund Shares may begin to mirror the liquidity of the Fund’s underlying portfolio holdings, which can be significantly less liquid than Fund Shares. Trading in Fund Shares on the Exchange may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in Fund Shares inadvisable. In addition, trading in Fund Shares on the Exchange is subject to trading halts caused by extraordinary market volatility pursuant to the Exchange’s “circuit breaker” rules. There can be no assurance that the requirements of the Exchange necessary to maintain the listing of the Fund will continue to be met or will remain unchanged. The Fund may have difficulty maintaining its listing on the Exchange in the event the Fund’s assets are small, the Fund does not have enough shareholders, or if the Fund is unable to proceed with creation and/or redemption orders.

 

U.S. GOVERNMENT SECURITIES RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

U.S. GOVERNMENT SECURITIES RISK. U.S. government securities are subject to interest rate risk but generally do not involve the credit risks associated with investments in other types of debt securities. As a result, the yields available from U.S. government securities are generally lower than the yields available from other debt securities. U.S. government securities are guaranteed only as to the timely payment of interest and the payment of principal when held to maturity.

 

VALUATION RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

VALUATION RISK. The Fund may hold securities or other assets that may be valued on the basis of factors other than market quotations. This may occur because the asset or security does not trade on a centralized exchange, or in times of market turmoil or reduced liquidity. There are multiple methods that can be used to value a portfolio holding when market quotations are not readily available. The value established for any portfolio holding at a point in time might differ from what would be produced using a different methodology or if it had been priced using market quotations. Portfolio holdings that are valued using techniques other than market quotations, including “fair valued” assets or securities, may be subject to greater fluctuation in their valuations from one day to the next than if market quotations were used. In addition, there is no assurance that the Fund could sell or close out a portfolio position for the value established for it at any time, and it is possible that the Fund would incur a loss because a portfolio position is sold or closed out at a discount to the valuation established by the Fund at that time. The Fund’s ability to value investments may be impacted by technological issues or errors by pricing services or other third-party service providers.

NON-DIVERSIFICATION RISK. The Fund is classified as “non-diversified” under the 1940 Act. As a result, the Fund is only limited as to the percentage of its assets which may be invested in the securities of any one issuer by the diversification requirements imposed by the Internal Revenue Code of 1986, as amended (the “Code”). The Fund may invest a relatively high percentage of its assets in a limited number of issuers. As a result, the Fund may be more susceptible to a single adverse economic or regulatory occurrence affecting one or more of these issuers, experience increased volatility and be highly invested in certain issuers.
