Strategy Narrative [Text Block]

The Fund, under normal circumstances, invests in swap agreements that provide 200% daily exposure to GME equal to at least 80% of its net assets (plus any borrowings for investment purposes). The Fund may also seek to achieve its investment objective by purchasing call options on GME or by investing directly in the common stock of GME. The Adviser will determine the allocation of the Fund’s investments in swap agreements, call options and direct investments in GME 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 GME is 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 GME 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 (GME) 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 GME 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 GME is assigned (i.e., hold 25% or more of its total assets in investments that provide leveraged exposure in the industry to which GME is assigned). As of the date of this prospectus, GME is assigned to the consumer discretionary sector and the specialty retail 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 GME. At the close of the markets each trading day, the Adviser rebalances the Fund’s portfolio so that its exposure to GME is consistent with the Fund’s investment objective. The impact of GME’s price movements during the day will affect whether the Fund’s portfolio needs to be rebalanced. For example, if the price of GME 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 GME 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 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.

GameStop Corp. is an American video game, consumer electronics, and gaming merchandise retailer. It also sells various related services. GME 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 GameStop Corp. pursuant to the Exchange Act can be located by reference to the Securities and Exchange Commission file number 1-32637 through the Securities and Exchange Commission’s website at www.sec.gov. In addition, information regarding GameStop Corp. may be obtained from other sources including, but not limited to, press releases, newspaper articles and other publicly disseminated documents. As of the date of this prospectus, GME is assigned to the consumer discretionary sector and the specialty retail industry.

The Fund has derived all disclosures contained in this document regarding GameStop Corp. 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 GameStop Corp. 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 GME have been publicly disclosed. Subsequent disclosure of any such events or the disclosure of, or failure to disclose, material future events concerning GameStop Corp. could affect the value of the Fund’s investments with respect to GME 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 in swap agreements that provide 200% inverse (opposite) daily exposure to MARA equal to at least 80% of the Fund’s net assets (plus borrowings for investment purposes). The Fund may also seek to achieve its investment objective by purchasing put options on MARA or by engaging in short sales of the common stock of MARA. The Adviser will determine the allocation of the Fund’s investments in swap agreements, put options and short sales of MARA 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. Short sales of the common stock of MARA is typically less efficient than the use of swap agreements because short sales 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 MARA that is equal, on a daily basis, to -200% of the value of the Fund’s net assets. If the Adviser determines to use put options, the Fund will purchase exchange traded put options, including “FLEX Options,” with MARA as the reference security. Put options give the holder (i.e., the buyer) the right to sell an asset and the seller (i.e., the writer) the obligation to purchase the asset 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.

If the Adviser determines to engage in short sales on the common stock of MARA, the Fund will sell shares of MARA that it has borrowed. When executing a short sale, the Fund borrows the security from a third party and sells it at the then current market price. The Fund is then obligated to buy the security on a later date and return the security to the lender. The Fund will realize a profit if the price of the underlying stock decreases or incur a loss if the price of the underlying stock increases while the Fund is holding the borrowed security. The Fund may reinvest the proceeds of its short sales.

The Adviser attempts to consistently apply leverage to obtain short MARA 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 MARA is assigned (i.e., hold 25% or more of its total assets in investments that provide inverse exposure in the industry to which MARA is assigned). As of the date of this prospectus, MARA is assigned to the information technology sector and the 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 MARA. At the close of the markets each trading day, the Adviser rebalances the Fund’s portfolio so that its exposure to MARA is consistent with the Fund’s investment objective. The impact of MARA’s

price movements during the day will affect whether the Fund’s portfolio needs to be rebalanced. For example, if the price of MARA has fallen 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 MARA has risen 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.

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.

MARA Holdings Inc. is a digital asset technology company, which engages in mining cryptocurrencies, with a focus on the blockchain ecosystem and the generation of digital assets. MARA 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 MARA Holdings Inc. pursuant to the Exchange Act can be located by reference to the Securities and Exchange Commission file number 001-36555 through the Securities and Exchange Commission’s website at www.sec.gov. In addition, information regarding MARA Holdings Inc. may be obtained from other sources including, but not limited to, press releases, newspaper articles and other publicly disseminated documents. As of the date of this prospectus, MARA is assigned to the information technology sector and the software industry.

The Fund has derived all disclosures contained in this document regarding MARA Holdings 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 MARA Holdings 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 MARA have been publicly disclosed. Subsequent disclosure of any such events or the disclosure of, or failure to disclose, material future events concerning MARA Holdings Inc. could affect the value of the Fund’s investments with respect to MARA 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 decreases 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 Portfolio Concentration [Text] The Fund, under normal circumstances, invests in swap agreements that provide 200% inverse (opposite) daily exposure to MARA equal to at least 80% of the Fund’s net assets (plus borrowings for investment purposes).

Strategy Narrative [Text Block]

The Fund, under normal circumstances, invests in swap agreements that provide 200% daily exposure to RBLX equal to at least 80% of its net assets (plus any borrowings for investment purposes). The Fund may also seek to achieve its investment objective by purchasing call options on RBLX or by investing directly in the common stock of RBLX. The Adviser will determine the allocation of the Fund’s investments in swap agreements, call options and direct investments in RBLX 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 RBLX is 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 RBLX 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 (RBLX) 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 RBLX 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 RBLX is assigned (i.e., hold 25% or more of its total assets in investments that provide leveraged exposure in the industry to which RBLX is assigned). As of the date of this prospectus, RBLX is assigned to the communication services sector and the entertainment 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 RBLX. At the close of the markets each trading day, the Adviser rebalances the Fund’s portfolio so that its exposure to RBLX is consistent with the Fund’s investment objective. The impact of RBLX’s price movements during the day will affect whether the Fund’s portfolio needs to be rebalanced. For example, if the price of RBLX 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 RBLX 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 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.

Strategy Narrative [Text Block]

The Fund, under normal circumstances, invests in swap agreements that provide 200% inverse (opposite) daily exposure to PLTR equal to at least 80% of the Fund’s net assets (plus borrowings for investment purposes). The Fund may also seek to achieve its investment objective by purchasing put options on PLTR or by engaging in short sales of the common stock of PLTR. The Adviser will determine the allocation of the Fund’s investments in swap agreements, put options and short sales of PLTR 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. Short sales of the common stock of PLTR is typically less efficient than the use of swap agreements because short sales 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 PLTR that is equal, on a daily basis, to -200% of the value of the Fund’s net assets. If the Adviser determines to use put options, the Fund will purchase exchange traded put options, including “FLEX Options,” with PLTR as the reference security. Put options give the holder (i.e., the buyer) the right to sell an asset and the seller (i.e., the writer) the obligation to purchase the asset 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.

If the Adviser determines to engage in short sales on the common stock of PLTR, the Fund will sell shares of PLTR that it has borrowed. When executing a short sale, the Fund borrows the security from a third party and sells it at the then current market price. The Fund is then obligated to buy the security on a later date and return the security to the lender. The Fund will realize a profit if the price of the underlying stock decreases or incur a loss if the price of the underlying stock increases while the Fund is holding the borrowed security. The Fund may reinvest the proceeds of its short sales.

The Adviser attempts to consistently apply leverage to obtain short PLTR 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 PLTR is assigned (i.e., hold 25% or more of its total assets in investments that provide inverse exposure in the industry to which PLTR is assigned). As of the date of this prospectus, PLTR is assigned to the information technology sector and the 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 PLTR. At the close of the markets each trading day, the Adviser rebalances the Fund’s portfolio so that its exposure to PLTR is consistent with the Fund’s investment objective.

The Fund may also seek to achieve its investment objective by purchasing call options on ARM or by investing directly in the ADRs of ARM. The Adviser will determine the allocation of the Fund’s investments in swap agreements, call options and direct investments in ARM ADRs based upon various factors including, but not limited to, counterparty capacity, financing charges, liquidity, collateral availability, and overall market conditions for a particular instrument.

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 in swap agreements that provide 200% inverse (opposite) daily exposure to SHOP equal to at least 80% of the Fund’s net assets (plus borrowings for investment purposes). The Fund may also seek to achieve its investment objective by purchasing put options on SHOP or by engaging in short sales of the common stock of SHOP. The Adviser will determine the allocation of the Fund’s investments in swap agreements, put options and short sales of SHOP 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. Short sales of the common stock of SHOP is typically less efficient than the use of swap agreements because short sales 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 SHOP that is equal, on a daily basis, to -200% of the value of the Fund’s net assets. If the Adviser determines to use put options, the Fund will purchase exchange traded put options, including “FLEX Options,” with SHOP as the reference security. Put options give the holder (i.e., the buyer) the right to sell an asset and the seller (i.e., the writer) the obligation to purchase the asset 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.

If the Adviser determines to engage in short sales on the common stock of SHOP, the Fund will sell shares of SHOP that it has borrowed. When executing a short sale, the Fund borrows the security from a third party and sells it at the then current market price. The Fund is then obligated to buy the security on a later date and return the security to the lender. The Fund will realize a profit if the price of the underlying stock decreases or incur a loss if the price of the underlying stock increases while the Fund is holding the borrowed security. The Fund may reinvest the proceeds of its short sales.

The Adviser attempts to consistently apply leverage to obtain short SHOP 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 SHOP is assigned (i.e., hold 25% or more of its total assets in investments that provide inverse exposure in the industry to which SHOP is assigned). As of the date of this prospectus, SHOP is assigned to the information technology sector and the 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 SHOP. At the close of the markets each trading day, the Adviser rebalances the Fund’s portfolio so that its exposure to SHOP is consistent with the Fund’s investment objective. The impact of SHOP’s

price movements during the day will affect whether the Fund’s portfolio needs to be rebalanced. For example, if the price of SHOP has fallen 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 SHOP has risen 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.

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.

When executing a short sale, the Fund borrows the security from a third party and sells it at the then current market price. The Fund is then obligated to buy the security on a later date and return the security to the lender. The Fund will realize a profit if the price of the underlying stock decreases or incur a loss if the price of the underlying stock increases while the Fund is holding the borrowed security. The Fund may reinvest the proceeds of its short sales.

The Adviser attempts to consistently apply leverage to obtain short SNOW 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 SNOW is assigned (i.e., hold 25% or more of its total assets in investments that provide inverse exposure in the industry to which SNOW is assigned). As of the date of this prospectus, SNOW is assigned to the information technology sector and the IT 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 SNOW. At the close of the markets each trading day, the Adviser rebalances the Fund’s portfolio so that its exposure to SNOW is consistent with the Fund’s investment objective. The impact of SNOW’s

price movements during the day will affect whether the Fund’s portfolio needs to be rebalanced. For example, if the price of SNOW has fallen 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 SNOW has risen 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.

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.

In addition, information regarding Snowflake Inc. may be obtained from other sources including, but not limited to, press releases, newspaper articles and other publicly disseminated documents. As of the date of this prospectus, SNOW is assigned to the information technology sector and the IT services industry.

The Fund has derived all disclosures contained in this document regarding Snowflake 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 Snowflake 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 SNOW have been publicly disclosed. Subsequent disclosure of any such events or the disclosure of, or failure to disclose, material future events concerning Snowflake Inc. could affect the value of the Fund’s investments with respect to SNOW 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 decreases 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 Portfolio Concentration [Text] The Fund, under normal circumstances, invests in swap agreements that provide 200% inverse (opposite) daily exposure to SNOW equal to at least 80% of the Fund’s net assets (plus borrowings for investment purposes).

The Fund, under normal circumstances, invests in swap agreements that provide 200% daily exposure to AVGO equal to at least 80% of its net assets (plus any borrowings for investment purposes). The Fund may also seek to achieve its investment objective by purchasing call options on AVGO or by investing directly in the common stock of AVGO. The Adviser will determine the allocation of the Fund’s investments in swap agreements, call options and direct investments in AVGO 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 AVGO is 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 AVGO 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 (AVGO) if it chooses to exercise a call option and either hold or sell the security in the secondary markets.

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, under normal circumstances, invests in swap agreements that provide 200% inverse (opposite) daily exposure to AVGO equal to at least 80% of the Fund’s net assets (plus borrowings for investment purposes). The Fund may also seek to achieve its investment objective by purchasing put options on AVGO or by engaging in short sales of the common stock of AVGO. The Adviser will determine the allocation of the Fund’s investments in swap agreements, put options and short sales of AVGO 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. Short sales of the common stock of AVGO is typically less efficient than the use of swap agreements because short sales 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 AVGO that is equal, on a daily basis, to -200% of the value of the Fund’s net assets. If the Adviser determines to use put options, the Fund will purchase exchange traded put options, including “FLEX Options,” with AVGO as the reference security. Put options give the holder (i.e., the buyer) the right to sell an asset and the seller (i.e., the writer) the obligation to purchase the asset at a certain defined price.

The FLEX Options are listed on the Chicago Board Options Exchange.

If the Adviser determines to engage in short sales on the common stock of AVGO, the Fund will sell shares of AVGO that it has borrowed. When executing a short sale, the Fund borrows the security from a third party and sells it at the then current market price. The Fund is then obligated to buy the security on a later date and return the security to the lender. The Fund will realize a profit if the price of the underlying stock decreases or incur a loss if the price of the underlying stock increases while the Fund is holding the borrowed security. The Fund may reinvest the proceeds of its short sales.

Subsequent disclosure of any such events or the disclosure of, or failure to disclose, material future events concerning Palo Alto Networks Inc. could affect the value of the Fund’s investments with respect to PANW 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 decreases 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, under normal circumstances, invests in swap agreements that provide 200% daily exposure to TSM equal to at least 80% of its net assets (plus any borrowings for investment purposes). The Fund may also seek to achieve its investment objective by purchasing call options on TSM or by investing directly in ADRs of TSM. The Adviser will determine the allocation of the Fund’s investments in swap agreements, call options and direct investments in TSM ADRs 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 ADRs of TSM is 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 TSM 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 (TSM) 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 TSM 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 TSM is assigned (i.e., hold 25% or more of its total assets in investments that provide leveraged exposure in the industry to which TSM is assigned). As of the date of this prospectus, TSM is assigned to the information technology sector and the semiconductors and semiconductor equipment 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 TSM. At the close of the markets each trading day, the Adviser rebalances the Fund’s portfolio so that its exposure to TSM is consistent with the Fund’s investment objective. The impact of TSM’s price movements during the day will affect whether the Fund’s portfolio needs to be rebalanced. For example, if the price of TSM 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 TSM 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 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 FLEX Options are listed on the Chicago Board Options Exchange.

If the Adviser determines to engage in short sales on the ADRs of TSM, the Fund will sell shares of TSM that it has borrowed. When executing a short sale, the Fund borrows the security from a third party and sells it at the then current market price. The Fund is then obligated to buy the security on a later date and return the security to the lender. The Fund will realize a profit if the price of the underlying stock decreases or incur a loss if the price of the underlying stock increases while the Fund is holding the borrowed security. The Fund may reinvest the proceeds of its short sales.

The Adviser attempts to consistently apply leverage to obtain short TSM 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 TSM is assigned (i.e., hold 25% or more of its total assets in investments that provide inverse exposure in the industry to which TSM is assigned).

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.

If the Adviser determines to engage in short sales on the common stock of COIN, the Fund will sell shares of COIN that it has borrowed. When executing a short sale, the Fund borrows the security from a third party and sells it at the then current market price. The Fund is then obligated to buy the security on a later date and return the security to the lender. The Fund will realize a profit if the price of the underlying stock decreases or incur a loss if the price of the underlying stock increases while the Fund is holding the borrowed security. The Fund may reinvest the proceeds of its short sales.

The Adviser attempts to consistently apply leverage to obtain short COIN 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 COIN is assigned (i.e., hold 25% or more of its total assets in investments that provide inverse exposure in the industry to which COIN is assigned). As of the date of this prospectus, COIN is assigned to the financial sector and the capital markets 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 COIN. At the close of the markets each trading day, the Adviser rebalances the Fund’s portfolio so that its exposure to COIN is consistent with the Fund’s investment objective. The impact of COIN’s

price movements during the day will affect whether the Fund’s portfolio needs to be rebalanced. For example, if the price of COIN has fallen 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 COIN has risen 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.

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.

Coinbase Global, Inc. operates as a secure hosted cryptocurrency exchange platform. COIN is registered under the Securities Exchange Act of 1934, as amended (the “Exchange Act”).

In addition, information regarding Coinbase Global, 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 Coinbase Global, 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 Coinbase Global, 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 COIN have been publicly disclosed. Subsequent disclosure of any such events or the disclosure of, or failure to disclose, material future events concerning Coinbase Global, Inc. could affect the value of the Fund’s investments with respect to COIN 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 decreases 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 Portfolio Concentration [Text] The Fund, under normal circumstances, invests in swap agreements that provide 200% inverse (opposite) daily exposure to COIN equal to at least 80% of the Fund’s net assets (plus borrowings for investment purposes).

The Fund, under normal circumstances, invests in swap agreements that provide 200% daily exposure to AAPL equal to at least 80% of its net assets (plus any borrowings for investment purposes). The Fund may also seek to achieve its investment objective by purchasing call options on AAPL or by investing directly in the common stock of AAPL. The Adviser will determine the allocation of the Fund’s investments in swap agreements, call options and direct investments in AAPL 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 AAPL is 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 AAPL 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.

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 (AAPL) if it chooses to exercise a call option and either hold or sell the security in the secondary markets.

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, under normal circumstances, invests in swap agreements that provide 200% inverse (opposite) daily exposure to GOOG equal to at least 80% of the Fund’s net assets (plus borrowings for investment purposes). The Fund may also seek to achieve its investment objective by purchasing put options on GOOG or by engaging in short sales of the common stock of GOOG. The Adviser will determine the allocation of the Fund’s investments in swap agreements, put options and short sales of GOOG 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. Short sales of the common stock of GOOG is typically less efficient than the use of swap agreements because short sales 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 GOOG that is equal, on a daily basis, to -200% of the value of the Fund’s net assets. If the Adviser determines to use put options, the Fund will purchase exchange traded put options, including “FLEX Options,” with GOOG as the reference security. Put options give the holder (i.e., the buyer) the right to sell an asset and the seller (i.e., the writer) the obligation to purchase the asset at a certain defined price.

The FLEX Options are listed on the Chicago Board Options Exchange.

If the Adviser determines to engage in short sales on the common stock of GOOG, the Fund will sell shares of GOOG that it has borrowed. When executing a short sale, the Fund borrows the security from a third party and sells it at the then current market price. The Fund is then obligated to buy the security on a later date and return the security to the lender. The Fund will realize a profit if the price of the underlying stock decreases or incur a loss if the price of the underlying stock increases while the Fund is holding the borrowed security. The Fund may reinvest the proceeds of its short sales.

The Adviser attempts to consistently apply leverage to obtain short GOOG 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 GOOG is assigned (i.e., hold 25% or more of its total assets in investments that provide inverse exposure in the industry to which GOOG is assigned). As of the date of this prospectus, GOOG is assigned to the communication services sector and interactive media & 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 GOOG. At the close of the markets each trading day, the Adviser rebalances the Fund’s portfolio so that its exposure to GOOG is consistent with the Fund’s investment objective. The impact of GOOG’s price movements during the day will affect whether the Fund’s portfolio needs to be rebalanced. For example, if the price of GOOG has fallen 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 GOOG has risen on a given day, net assets of the Fund should fall, meaning the Fund’s exposure will need to be reduced.

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 decreases over a period longer than a single day.

Strategy Portfolio Concentration [Text] The Fund, under normal circumstances, invests in swap agreements that provide 200% inverse (opposite) daily exposure to GOOG equal to at least 80% of the Fund’s net assets (plus borrowings for investment purposes).

The Fund, under normal circumstances, invests in swap agreements that provide 200% daily exposure to MSFT equal to at least 80% of its net assets (plus any borrowings for investment purposes). The Fund may also seek to achieve its investment objective by purchasing call options on MSFT or by investing directly in the common stock of MSFT. The Adviser will determine the allocation of the Fund’s investments in swap agreements, call options and direct investments in MSFT 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 MSFT is 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 MSFT 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 (MSFT) 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 MSFT 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 MSFT is assigned (i.e., hold 25% or more of its total assets in investments that provide leveraged exposure in the industry to which MSFT is assigned). As of the date of this prospectus, MSFT 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 MSFT. At the close of the markets each trading day, the Adviser rebalances the Fund’s portfolio so that its exposure to MSFT is consistent with the Fund’s investment objective. The impact of MSFT’s price movements during the day will affect whether the Fund’s portfolio needs to be rebalanced. For example, if the price of MSFT 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 MSFT 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 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 Fund, under normal circumstances, invests in swap agreements that provide 200% inverse (opposite) daily exposure to MSFT equal to at least 80% of the Fund’s net assets (plus borrowings for investment purposes). The Fund may also seek to achieve its investment objective by purchasing put options on MSFT or by engaging in short sales of the common stock of MSFT. The Adviser will determine the allocation of the Fund’s investments in swap agreements, put options and short sales of MSFT 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. Short sales of the common stock of MSFT is typically less efficient than the use of swap agreements because short sales 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 MSFT that is equal, on a daily basis, to -200% of the value of the Fund’s net assets. If the Adviser determines to use put options, the Fund will purchase exchange traded put options, including “FLEX Options,” with MSFT as the reference security. Put options give the holder (i.e., the buyer) the right to sell an asset and the seller (i.e., the writer) the obligation to purchase the asset 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.

If the Adviser determines to engage in short sales on the common stock of MSFT, the Fund will sell shares of MSFT that it has borrowed. When executing a short sale, the Fund borrows the security from a third party and sells it at the then current market price. The Fund is then obligated to buy the security on a later date and return the security to the lender. The Fund will realize a profit if the price of the underlying stock decreases or incur a loss if the price of the underlying stock increases while the Fund is holding the borrowed security. The Fund may reinvest the proceeds of its short sales.

The Adviser attempts to consistently apply leverage to obtain short MSFT 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 MSFT is assigned (i.e., hold 25% or more of its total assets in investments that provide inverse exposure in the industry to which MSFT is assigned). As of the date of this prospectus, MSFT is assigned to the technology sector and the computer software industry.
