| Prospectus [Line Items] | |
| Strategy [Heading] | Principal Investment Strategies |
| Strategy Narrative [Text Block] | The Fund, under normal circumstances, invests at least 80% of its net assets (plus any borrowings for investment purposes) in financial instruments that are designed to provide, in the aggregate, 200% exposure to the price performance of ALMU on a daily basis. The Fund may also seek to achieve its investment objective by purchasing call options on ALMU or by investing directly in the common stock of ALMU. The Adviser will determine the allocation of the Fund’s investments in swap agreements, call options and direct investments in ALMU common stock based upon various factors including, but not limited to, counterparty capacity, financing charges, liquidity, collateral availability, and overall market conditions for a particular instrument. Direct investments in common stock of ALMU are typically less efficient than the use of swap agreements because direct investments in common stock do not provide leveraged returns. This may result in the Fund not achieving its 200% daily investment objective. The Fund will enter into one or more swap agreements with financial institutions whereby the Fund and the financial institution will agree to exchange the return earned on an investment by the Fund in ALMU that is equal, on a daily basis, to 200% of the value of the Fund's net assets. If the Adviser determines to use call options, the Fund will purchase exchange traded call options, including “FLEX Options.” Call options give the holder (i.e., the buyer) the right to buy an asset (or receive cash value of the asset, in case of certain call options) and the seller (i.e., the writer) the obligation to sell the asset (or deliver cash value of the asset, in case of certain call options) at a certain defined price. FLexible EXchange® Options (“FLEX Options”) are customized options contracts that trade on an exchange but provide investors with the ability to customize key contract terms like strike price, style and expiration date while achieving price discovery in competitive, transparent auctions markets and avoiding the counterparty exposure of over-the-counter (OTC) options positions. Like traditional exchange-traded options, FLEX Options are guaranteed for settlement by the OCC, a market clearinghouse that guarantees performance by counterparties to certain derivatives contracts. The FLEX Options are listed on the Chicago Board Options Exchange. The Fund may take delivery of the underlying security (ALMU) if it chooses to exercise a call option and either hold or sell the security in the secondary markets. The Adviser attempts to consistently apply leverage to obtain ALMU exposure for the Fund equal to 200% of the value of its net assets and expects to rebalance the Fund’s holdings daily to maintain such exposure. As a result of its investment strategies, the Fund will be concentrated in the industry to which ALMU is assigned (i.e., hold 25% or more of its total assets in investments that provide leveraged exposure in the industry to which ALMU is assigned). As of the date of this prospectus, ALMU is assigned to the technology sector and the semiconductors industry. The Fund will attempt to achieve its investment objective without regard to overall market movement or the increase or decrease of the value of ALMU. At the close of the markets each trading day, the Adviser rebalances the Fund’s portfolio so that its exposure to ALMU is consistent with the Fund’s investment objective. The impact of ALMU’s price movements during the day will affect whether the Fund’s portfolio needs to be rebalanced. For example, if the price of ALMU has risen on a given day, net assets of the Fund should rise, meaning that the Fund’s exposure will need to be increased. Conversely, if the price of ALMU has fallen on a given day, net assets of the Fund should fall, meaning the Fund’s exposure will need to be reduced. This daily rebalancing typically results in high portfolio turnover. On a day-to-day basis, the Fund is expected to hold money market funds, deposit accounts with institutions with high quality (investment grade) credit ratings, and/or short-term debt instruments that have terms-to-maturity of less than 397 days and exhibit high quality (investment grade) credit profiles, including U.S. government securities and repurchase agreements. Generally, the Fund pursues its investment objective regardless of market conditions and does not generally take defensive positions. If the Fund’s underlying security moves more than 50% on a given trading day in a direction adverse to the Fund, the Fund’s investors would lose all of their money. The Fund may invest in other exchange-traded funds for cash management purposes. Such exchange-traded funds may include The Laddered T-Bill ETF, a series of the REX ETF Trust, which the Board of Trustees of the Fund has determined to be within the same group of investment companies as the Fund. The terms “daily,” “day,” and “trading day,” refer to the period from the close of the markets on one trading day to the close of the markets on the next trading day. The Fund is “non-diversified,” under the Investment Company Act of 1940, as amended. Additionally, the Fund’s investment objective is not a fundamental policy and may be changed by the Fund’s Board of Trustees without shareholder approval. Aeluma, Inc. develops optoelectronic and electronic devices for sensing, communication, and computing applications in the United States. As of April 2026, the market capitalization of Aeluma, Inc. is approximately $300 million. ALMU is registered under the Securities Exchange Act of 1934, as amended (the “Exchange Act”). Information provided to or filed with the Securities and Exchange Commission by Aeluma, Inc. pursuant to the Exchange Act can be located by reference to the Securities and Exchange Commission file number 001-42570 through the Securities and Exchange Commission’s website at www.sec.gov. In addition, information regarding Aeluma, Inc. may be obtained from other sources including, but not limited to, press releases, newspaper articles and other publicly disseminated documents. The Fund has derived all disclosures contained in this document regarding Aeluma, Inc. from the publicly available documents described above. Neither the Fund, the Trust, the Adviser nor any affiliate has participated in the preparation of such documents. Neither the Fund, the Trust, the Adviser nor any affiliate makes any representation that such publicly available documents or any other publicly available information regarding Aeluma, Inc. is accurate or complete. Furthermore, the Fund cannot give any assurance that all events occurring prior to the date of the prospectus (including events that would affect the accuracy or completeness of the publicly available documents described above) that would affect the trading price of ALMU have been publicly disclosed. Subsequent disclosure of any such events or the disclosure of, or failure to disclose, material future events concerning Aeluma, Inc. could affect the value of the Fund’s investments with respect to ALMU and therefore the value of the Fund. Because of daily rebalancing and the compounding of each day’s return over time, the return of the Fund for periods longer than a single day will be the result of each day’s returns compounded over the period, which will very likely differ from 200% of the return of the underlying security over the same period. The Fund will lose money if the underlying security performance is flat over time, and as a result of daily rebalancing, the underlying security’s volatility and the effects of compounding, it is even possible that the Fund will lose money over time while the underlying security’s performance increases over a period longer than a single day. The Fund may enter into swap agreements with a limited number of counterparties. If the underlying security has a dramatic move in price that causes a material decline in the Fund’s NAV over certain stated periods agreed to by the Fund and the counterparty, the terms of a swap agreement between a Fund and its counterparty may permit the counterparty to immediately close out all swap transactions with the Fund. There is a risk that no suitable counterparties will be willing to enter into, or continue to enter into, transactions with the Fund and, as a result, the Fund may not be able to achieve its leveraged investment objective or may decide to change its leveraged investment objective.

The Fund may take delivery of the underlying security (COMP) if it chooses to exercise a call option and either hold or sell the security in the secondary markets. The Adviser attempts to consistently apply leverage to obtain COMP exposure for the Fund equal to 200% of the value of its net assets and expects to rebalance the Fund’s holdings daily to maintain such exposure. As a result of its investment strategies, the Fund will be concentrated in the industry to which COMP is assigned (i.e., hold 25% or more of its total assets in investments that provide leveraged exposure in the industry to which COMP is assigned). As of the date of this prospectus, COMP is assigned to the real estate sector and the real estate services industry. The Fund will attempt to achieve its investment objective without regard to overall market movement or the increase or decrease of the value of COMP. At the close of the markets each trading day, the Adviser rebalances the Fund’s portfolio so that its exposure to COMP is consistent with the Fund’s investment objective. The impact of COMP’s price movements during the day will affect whether the Fund’s portfolio needs to be rebalanced. For example, if the price of COMP has risen on a given day, net assets of the Fund should rise, meaning that the Fund’s exposure will need to be increased. Conversely, if the price of COMP has fallen on a given day, net assets of the Fund should fall, meaning the Fund’s exposure will need to be reduced. This daily rebalancing typically results in high portfolio turnover. On a day-to-day basis, the Fund is expected to hold money market funds, deposit accounts with institutions with high quality (investment grade) credit ratings, and/or short-term debt instruments that have terms-to-maturity of less than 397 days and exhibit high quality (investment grade) credit profiles, including U.S. government securities and repurchase agreements. Generally, the Fund pursues its investment objective regardless of market conditions and does not generally take defensive positions. If the Fund’s underlying security moves more than 50% on a given trading day in a direction adverse to the Fund, the Fund’s investors would lose all of their money. The Fund may invest in other exchange-traded funds for cash management purposes. Such exchange-traded funds may include The Laddered T-Bill ETF, a series of the REX ETF Trust, which the Board of Trustees of the Fund has determined to be within the same group of investment companies as the Fund. The terms “daily,” “day,” and “trading day,” refer to the period from the close of the markets on one trading day to the close of the markets on the next trading day. The Fund is “non-diversified,” under the Investment Company Act of 1940, as amended. Additionally, the Fund’s investment objective is not a fundamental policy and may be changed by the Fund’s Board of Trustees without shareholder approval. Compass, Inc. operates a company-owned and franchised real estate brokerage business under various brands, and provides an end-to-end technology platform for residential real estate. The company offers the Compass Platform, a technology platform that provides an integrated suite of cloud-based software for customer relationship management, marketing, client service, brokerage services, and other functionalities for the real estate industry, as well as title, escrow, and mortgage services. As of April 2026, the market capitalization of Compass, Inc. is approximately $6.1 billion. COMP is registered under the Securities Exchange Act of 1934, as amended (the “Exchange Act”). Information provided to or filed with the Securities and Exchange Commission by Compass, Inc. pursuant to the Exchange Act can be located by reference to the Securities and Exchange Commission file number 001-40291 through the Securities and Exchange Commission’s website at www.sec.gov. In addition, information regarding Compass, Inc. may be obtained from other sources including, but not limited to, press releases, newspaper articles and other publicly disseminated documents. The Fund has derived all disclosures contained in this document regarding Compass, Inc. from the publicly available documents described above. Neither the Fund, the Trust, the Adviser nor any affiliate has participated in the preparation of such documents. Neither the Fund, the Trust, the Adviser nor any affiliate makes any representation that such publicly available documents or any other publicly available information regarding Compass, Inc. is accurate or complete. Furthermore, the Fund cannot give any assurance that all events occurring prior to the date of the prospectus (including events that would affect the accuracy or completeness of the publicly available documents described above) that would affect the trading price of COMP have been publicly disclosed. Subsequent disclosure of any such events or the disclosure of, or failure to disclose, material future events concerning Compass, Inc. could affect the value of the Fund’s investments with respect to COMP and therefore the value of the Fund. Because of daily rebalancing and the compounding of each day’s return over time, the return of the Fund for periods longer than a single day will be the result of each day’s returns compounded over the period, which will very likely differ from 200% of the return of the underlying security over the same period. The Fund will lose money if the underlying security performance is flat over time, and as a result of daily rebalancing, the underlying security’s volatility and the effects of compounding, it is even possible that the Fund will lose money over time while the underlying security’s performance increases over a period longer than a single day. The Fund may enter into swap agreements with a limited number of counterparties. If the underlying security has a dramatic move in price that causes a material decline in the Fund’s NAV over certain stated periods agreed to by the Fund and the counterparty, the terms of a swap agreement between a Fund and its counterparty may permit the counterparty to immediately close out all swap transactions with the Fund. There is a risk that no suitable counterparties will be willing to enter into, or continue to enter into, transactions with the Fund and, as a result, the Fund may not be able to achieve its leveraged investment objective or may decide to change its leveraged investment objective.

| Strategy Narrative [Text Block] | The Fund, under normal circumstances, invests at least 80% of its net assets (plus any borrowings for investment purposes) in financial instruments that are designed to provide, in the aggregate, 200% exposure to the price performance of ERO on a daily basis. The Fund may also seek to achieve its investment objective by purchasing call options on ERO or by investing directly in the common stock of ERO. The Adviser will determine the allocation of the Fund’s investments in swap agreements, call options and direct investments in ERO common stock based upon various factors including, but not limited to, counterparty capacity, financing charges, liquidity, collateral availability, and overall market conditions for a particular instrument. Direct investments in common stock of ERO are typically less efficient than the use of swap agreements because direct investments in common stock do not provide leveraged returns. This may result in the Fund not achieving its 200% daily investment objective. The Fund will enter into one or more swap agreements with financial institutions whereby the Fund and the financial institution will agree to exchange the return earned on an investment by the Fund in ERO that is equal, on a daily basis, to 200% of the value of the Fund's net assets. If the Adviser determines to use call options, the Fund will purchase exchange traded call options, including “FLEX Options.” Call options give the holder (i.e., the buyer) the right to buy an asset (or receive cash value of the asset, in case of certain call options) and the seller (i.e., the writer) the obligation to sell the asset (or deliver cash value of the asset, in case of certain call options) at a certain defined price. FLexible EXchange® Options (“FLEX Options”) are customized options contracts that trade on an exchange but provide investors with the ability to customize key contract terms like strike price, style and expiration date while achieving price discovery in competitive, transparent auctions markets and avoiding the counterparty exposure of over-the-counter (OTC) options positions. Like traditional exchange-traded options, FLEX Options are guaranteed for settlement by the OCC, a market clearinghouse that guarantees performance by counterparties to certain derivatives contracts.

If the Fund’s underlying security moves more than 50% on a given trading day in a direction adverse to the Fund, the Fund’s investors would lose all of their money. The Fund may invest in other exchange-traded funds for cash management purposes. Such exchange-traded funds may include The Laddered T-Bill ETF, a series of the REX ETF Trust, which the Board of Trustees of the Fund has determined to be within the same group of investment companies as the Fund. The terms “daily,” “day,” and “trading day,” refer to the period from the close of the markets on one trading day to the close of the markets on the next trading day. The Fund is “non-diversified,” under the Investment Company Act of 1940, as amended. Additionally, the Fund’s investment objective is not a fundamental policy and may be changed by the Fund’s Board of Trustees without shareholder approval. NU Holdings Ltd. provides a digital banking platform in Brazil, Mexico, Colombia, the Cayman Islands, and the United States. As of April 2026, the market capitalization of NU Holdings Ltd. is approximately $75 billion. NU is organized in the Cayman Islands and is headquartered in Brazil, and is registered under the Securities Exchange Act of 1934, as amended (the “Exchange Act”). Information provided to or filed with the Securities and Exchange Commission by NU Holdings Ltd. pursuant to the Exchange Act can be located by reference to the Securities and Exchange Commission file number 001-41129 through the Securities and Exchange Commission’s website at www.sec.gov. In addition, information regarding NU Holdings Ltd. may be obtained from other sources including, but not limited to, press releases, newspaper articles and other publicly disseminated documents. The Fund has derived all disclosures contained in this document regarding NU Holdings Ltd. from the publicly available documents described above. Neither the Fund, the Trust, the Adviser nor any affiliate has participated in the preparation of such documents. Neither the Fund, the Trust, the Adviser nor any affiliate makes any representation that such publicly available documents or any other publicly available information regarding NU Holdings Ltd. is accurate or complete. Furthermore, the Fund cannot give any assurance that all events occurring prior to the date of the prospectus (including events that would affect the accuracy or completeness of the publicly available documents described above) that would affect the trading price of NU have been publicly disclosed. Subsequent disclosure of any such events or the disclosure of, or failure to disclose, material future events concerning NU Holdings Ltd. could affect the value of the Fund’s investments with respect to NU and therefore the value of the Fund. Because of daily rebalancing and the compounding of each day’s return over time, the return of the Fund for periods longer than a single day will be the result of each day’s returns compounded over the period, which will very likely differ from 200% of the return of the underlying security over the same period. The Fund will lose money if the underlying security performance is flat over time, and as a result of daily rebalancing, the underlying security’s volatility and the effects of compounding, it is even possible that the Fund will lose money over time while the underlying security’s performance increases over a period longer than a single day. The Fund may enter into swap agreements with a limited number of counterparties. If the underlying security has a dramatic move in price that causes a material decline in the Fund’s NAV over certain stated periods agreed to by the Fund and the counterparty, the terms of a swap agreement between a Fund and its counterparty may permit the counterparty to immediately close out all swap transactions with the Fund. There is a risk that no suitable counterparties will be willing to enter into, or continue to enter into, transactions with the Fund and, as a result, the Fund may not be able to achieve its leveraged investment objective or may decide to change its leveraged investment objective.

| Strategy Narrative [Text Block] | The Fund, under normal circumstances, invests at least 80% of its net assets (plus any borrowings for investment purposes) in financial instruments that are designed to provide, in the aggregate, 200% exposure to the price performance of RCT on a daily basis. The Fund may also seek to achieve its investment objective by purchasing call options on RCT or by investing directly in the common stock of RCT. The Adviser will determine the allocation of the Fund’s investments in swap agreements, call options and direct investments in RCT common stock based upon various factors including, but not limited to, counterparty capacity, financing charges, liquidity, collateral availability, and overall market conditions for a particular instrument. Direct investments in common stock of RCT are typically less efficient than the use of swap agreements because direct investments in common stock do not provide leveraged returns. This may result in the Fund not achieving its 200% daily investment objective. The Fund will enter into one or more swap agreements with financial institutions whereby the Fund and the financial institution will agree to exchange the return earned on an investment by the Fund in RCT that is equal, on a daily basis, to 200% of the value of the Fund's net assets. If the Adviser determines to use call options, the Fund will purchase exchange traded call options, including “FLEX Options.” Call options give the holder (i.e., the buyer) the right to buy an asset (or receive cash value of the asset, in case of certain call options) and the seller (i.e., the writer) the obligation to sell the asset (or deliver cash value of the asset, in case of certain call options) at a certain defined price. FLexible EXchange® Options (“FLEX Options”) are customized options contracts that trade on an exchange but provide investors with the ability to customize key contract terms like strike price, style and expiration date while achieving price discovery in competitive, transparent auctions markets and avoiding the counterparty exposure of over-the-counter (OTC) options positions. Like traditional exchange-traded options, FLEX Options are guaranteed for settlement by the OCC, a market clearinghouse that guarantees performance by counterparties to certain derivatives contracts. The FLEX Options are listed on the Chicago Board Options Exchange. The Fund may take delivery of the underlying security (RCT) if it chooses to exercise a call option and either hold or sell the security in the secondary markets. The Adviser attempts to consistently apply leverage to obtain RCT exposure for the Fund equal to 200% of the value of its net assets and expects to rebalance the Fund’s holdings daily to maintain such exposure. As a result of its investment strategies, the Fund will be concentrated in the industry to which RCT is assigned (i.e., hold 25% or more of its total assets in investments that provide leveraged exposure in the industry to which RCT is assigned). As of the date of this prospectus, RCT is assigned to the technology sector and the computer software industry. The Fund will attempt to achieve its investment objective without regard to overall market movement or the increase or decrease of the value of RCT. At the close of the markets each trading day, the Adviser rebalances the Fund’s portfolio so that its exposure to RCT is consistent with the Fund’s investment objective. The impact of RCT’s price movements during the day will affect whether the Fund’s portfolio needs to be rebalanced. For example, if the price of RCT has risen on a given day, net assets of the Fund should rise, meaning that the Fund’s exposure will need to be increased. Conversely, if the price of RCT has fallen on a given day, net assets of the Fund should fall, meaning the Fund’s exposure will need to be reduced. This daily rebalancing typically results in high portfolio turnover. On a day-to-day basis, the Fund is expected to hold money market funds, deposit accounts with institutions with high quality (investment grade) credit ratings, and/or short-term debt instruments that have terms-to-maturity of less than 397 days and exhibit high quality (investment grade) credit profiles, including U.S. government securities and repurchase agreements.

Neither the Fund, the Trust, the Adviser nor any affiliate makes any representation that such publicly available documents or any other publicly available information regarding Southern Copper Corporation is accurate or complete. Furthermore, the Fund cannot give any assurance that all events occurring prior to the date of the prospectus (including events that would affect the accuracy or completeness of the publicly available documents described above) that would affect the trading price of SCCO have been publicly disclosed. Subsequent disclosure of any such events or the disclosure of, or failure to disclose, material future events concerning Southern Copper Corporation could affect the value of the Fund’s investments with respect to SCCO and therefore the value of the Fund. Because of daily rebalancing and the compounding of each day’s return over time, the return of the Fund for periods longer than a single day will be the result of each day’s returns compounded over the period, which will very likely differ from 200% of the return of the underlying security over the same period. The Fund will lose money if the underlying security performance is flat over time, and as a result of daily rebalancing, the underlying security’s volatility and the effects of compounding, it is even possible that the Fund will lose money over time while the underlying security’s performance increases over a period longer than a single day. The Fund may enter into swap agreements with a limited number of counterparties. If the underlying security has a dramatic move in price that causes a material decline in the Fund’s NAV over certain stated periods agreed to by the Fund and the counterparty, the terms of a swap agreement between a Fund and its counterparty may permit the counterparty to immediately close out all swap transactions with the Fund. There is a risk that no suitable counterparties will be willing to enter into, or continue to enter into, transactions with the Fund and, as a result, the Fund may not be able to achieve its leveraged investment objective or may decide to change its leveraged investment objective.

| Strategy Narrative [Text Block] | The Fund, under normal circumstances, invests at least 80% of its net assets (plus any borrowings for investment purposes) in financial instruments that are designed to provide, in the aggregate, 200% exposure to the price performance of SIL on a daily basis. The Fund may also seek to achieve its investment objective by purchasing call options on SIL or by investing directly in the shares of SIL. The Adviser will determine the allocation of the Fund’s investments in swap agreements, call options and direct investments in SIL shares based upon various factors including, but not limited to, counterparty capacity, financing charges, liquidity, collateral availability, and overall market conditions for a particular instrument. Direct investments in shares of SIL are typically less efficient than the use of swap agreements because direct investments in shares do not provide leveraged returns. This may result in the Fund not achieving its 200% daily investment objective. The Fund will enter into one or more swap agreements with financial institutions whereby the Fund and the financial institution will agree to exchange the return earned on an investment by the Fund in SIL that is equal, on a daily basis, to 200% of the value of the Fund's net assets. If the Adviser determines to use call options, the Fund will purchase exchange traded call options, including “FLEX Options.” Call options give the holder (i.e., the buyer) the right to buy an asset (or receive cash value of the asset, in case of certain call options) and the seller (i.e., the writer) the obligation to sell the asset (or deliver cash value of the asset, in case of certain call options) at a certain defined price. FLexible EXchange® Options (“FLEX Options”) are customized options contracts that trade on an exchange but provide investors with the ability to customize key contract terms like strike price, style and expiration date while achieving price discovery in competitive, transparent auctions markets and avoiding the counterparty exposure of over-the-counter (OTC) options positions. Like traditional exchange-traded options, FLEX Options are guaranteed for settlement by the OCC, a market clearinghouse that guarantees performance by counterparties to certain derivatives contracts. The FLEX Options are listed on the Chicago Board Options Exchange. The Fund may take delivery of the underlying security (SIL) if it chooses to exercise a call option and either hold or sell the security in the secondary markets. The Adviser attempts to consistently apply leverage to obtain SIL exposure for the Fund equal to 200% of the value of its net assets and expects to rebalance the Fund’s holdings daily to maintain such exposure. As a result of its investment strategies, the Fund will be concentrated indirectly in the industry to which SIL is concentrated (i.e., the industry in which SIL holds 25% or more of its total assets). SIL concentrates its investments in a particular industry or group of industries to approximately the same extent that the index that it seeks to replicate is concentrated. As of the date of this prospectus, SIL was concentrated in the metals and mining industry and had significant exposure to the materials sector. The Fund will attempt to achieve its investment objective without regard to overall market movement or the increase or decrease of the value of SIL. At the close of the markets each trading day, the Adviser rebalances the Fund’s portfolio so that its exposure to SIL is consistent with the Fund’s investment objective. The impact of SIL’s price movements during the day will affect whether the Fund’s portfolio needs to be rebalanced. For example, if the price of SIL has risen on a given day, net assets of the Fund should rise, meaning that the Fund’s exposure will need to be increased. Conversely, if the price of SIL has fallen on a given day, net assets of the Fund should fall, meaning the Fund’s exposure will need to be reduced. This daily rebalancing typically results in high portfolio turnover. On a day-to-day basis, the Fund is expected to hold money market funds, deposit accounts with institutions with high quality (investment grade) credit ratings, and/or short-term debt instruments that have terms-to-maturity of less than 397 days and exhibit high quality (investment grade) credit profiles, including U.S. government securities and repurchase agreements. Generally, the Fund pursues its investment objective regardless of market conditions and does not generally take defensive positions. If the Fund’s underlying security moves more than 50% on a given trading day in a direction adverse to the Fund, the Fund’s investors would lose all of their money. The Fund may invest in other exchange-traded funds for cash management purposes. Such exchange-traded funds may include The Laddered T-Bill ETF, a series of the REX ETF Trust, which the Board of Trustees of the Fund has determined to be within the same group of investment companies as the Fund. The terms “daily,” “day,” and “trading day,” refer to the period from the close of the markets on one trading day to the close of the markets on the next trading day. The Fund is “non-diversified,” under the Investment Company Act of 1940, as amended. Additionally, the Fund’s investment objective is not a fundamental policy and may be changed by the Fund’s Board of Trustees without shareholder approval. The Global X Silver Miners ETF is an ETF managed by Global X Management Company LLC.
