| Strategy Narrative [Text Block] | The Fund, under normal circumstances, invests at least 80% of the Fund’s net assets (plus borrowings for investment purposes) in financial instruments, including swap agreements and options, that, in combination, provide (1X) daily inverse (opposite) or short exposure to TOPT, consistent with the Fund’s investment objective.TOPT seeks to track the investment results of the S&P 500 Top 20 Select Index (the “S&P Index”), which measures the performance of the 20 largest U.S. companies by float-adjusted market capitalization within the S&P 500® as determined by S&P Dow Jones Indices LLC. The securities in the S&P Index are weighted based on the float-adjusted market value of their outstanding shares subject to capping. For capping purposes, the S&P Index will be rebalanced on a quarterly basis. At each quarterly rebalance in March, June, September, and December, the weight of any single issuer will not exceed 22.5% of the S&P Index; and the aggregate weight of issuers with individual weights exceeding 4.5% will not exceed 48% of the S&P Index. Between rebalances, constituent weights may exceed these constraints due to fluctuations in market value, corporate actions, or other events that change the index composition. TOPT 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 iShares Trust pursuant to the Exchange Act can be located by reference to the Securities and Exchange Commission file number 333-92935 through the Securities and Exchange Commission’s website at www.sec.gov. In addition, information regarding TOPT may be obtained from other sources including, but not limited to, press releases, newspaper articles and other publicly disseminated documents. The Fund will enter into one or more swap agreements with major global financial institutions whereby the Fund and the global financial institution will agree to exchange the return earned on an investment by the Fund in TOPT that is equal, on a daily basis, to -100% of the value of the Fund's net assets. The Adviser attempts to consistently apply leverage to obtain short TOPT exposure for the Fund equal to -100% 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 information technology sector (i.e., hold 25% or more of its total assets in investments that provide inverse exposure in the information technology 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 TOPT. At the close of the markets each trading day, the Adviser rebalances the Fund’s portfolio so that its exposure to TOPT is consistent with the Fund’s investment objective. The impact of TOPT’s price movements during the day will affect whether the Fund’s portfolio needs to be rebalanced. For example, if the price of TOPT 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 TOPT 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. In addition, 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. The Fund has derived all disclosures contained in this document regarding iShares Top 20 U.S. Stocks ETF 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 iShares Top 20 U.S. Stocks ETF 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 TOPT have been publicly disclosed. Subsequent disclosure of any such events or the disclosure of, or failure to disclose, material future events concerning iShares Top 20 U.S. Stocks ETF could affect the value of the Fund’s investments with respect to TOPT 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 -100% of the return of the underlying ETF over the same period. The Fund will lose money if the underlying ETF performance is flat over time, and as a result of daily rebalancing, the underlying ETF’s volatility and the effects of compounding, it is even possible that the Fund will lose money over time while the underlying ETF’s performance decreases over a period longer than a single day. |

The Nasdaq Index is a subset of the Nasdaq-100 Index. The securities in the Nasdaq Index are weighted based on the market value of their outstanding shares subject to capping.

| Strategy Narrative [Text Block] | The Index is designed by Solactive AG (the "Index Provider") to represent the securities of the next generation of U.S. companies that utilize quantum technology to improve the provision of their products and/or services. Quantum technology is a class of technology that use the principles of quantum mechanics (the physics of sub-atomic particles) to make advances in computing and other processes. The Index is a rules-based index and includes U.S.-listed securities of companies in the following quantum technology segments (each, a “Quantum Technology Segment”): ●Quantum Computing Infrastructure and Hardware: This segment encompasses companies that develop and provide the essential physical components, systems, and comprehensive environments necessary for quantum computing, including both hardware and infrastructure services. ●Quantum AI and Machine Learning: This segment focuses on companies that integrate artificial intelligence and machine learning with quantum computing to enhance problem-solving and algorithm efficiency. ●Quantum Software and Applications: Within this segment, companies are dedicated to create software tools and applications to operate quantum computers and utilize their computational power for various specialized tasks. ●Quantum AI and Cryptography: This segment addresses companies that develop quantum-based security mechanisms and engage in advanced research and development to push the boundaries of quantum technologies. To be selected for inclusion in the Index, a security must have a free float market capitalization of at least $100 million (or at least $90 billion for current constituents) and a minimum average daily traded value of at least $1 million over 1 month and over 6 months (or at least $900,000 for current constituents). To identify companies that use quantum technology, the Index Provider uses ARTIS®, its proprietary natural language processing algorithm, to identify into which Quantum Technology Segment(s) a company falls. ARTIS uses keywords to review large volumes of publicly available data, such as company annual reports, published business descriptions, and financial news reports, which the Index Provider believes will identify and classify companies as quantum technology companies, and then ranks the companies based on the number of keyword “hits” in the company’s data. The ARTIS classification system is different than traditional classification systems because it utilizes natural language processing, such as keyword searching, whereas traditional classifications system utilize backward looking metrics, such as a company’s past profits or revenue, to determine the classification of a company. ARTIS produces a score for each company that reflects the company's exposure to quantum technology and considers each Quantum Technology Segment to which a company belongs. Each company is then ranked by its score, and the top 20 companies are selected for inclusion in the Index. The Index is rebalanced semi-annually. As of January 30, 2026, the Index included 20 constituents and were concentrated in the information technology sector with exposure to quantum technology.The Fund, under normal circumstances, invests at least 80% of the Fund’s net assets (plus borrowing for investment purposes) in financial instruments, including swap agreements, futures contracts, or short positions, that, in combination, provide 1X daily inverse (opposite) or short exposure to the Index or to exchange-traded fund ("ETF") that track the Index, consistent with the Fund’s investment objective.The components of the Index and the percentages represented by various sectors in the Index may change over time. The Fund will concentrate its investment in a particular industry or group of industries (i.e., hold 25% or more of its total assets in investments that provide inverse leveraged exposure to a particular industry or group of industries) to approximately the same extent as the Index is so concentrated. The Fund may also gain inverse exposure by investing in a combination of financial instruments, such as swap agreements or futures agreements that provide short exposure to the Index, to a representative sample of the securities in the Index that has aggregate characteristics similar to those of the Index or to an ETF that tracks the same Index or a substantially similar index, or the Fund may short securities of the Index, or short an ETF that tracks the same Index or a substantially similar index. The Fund invests in derivatives as a substitute for directly shorting securities in order to gain inverse exposure to the Index or its components. When the Fund shorts securities, including the securities of another investment company, it borrows shares of that security or investment company, which it then sells. The Fund closes out a short sale by purchasing the security that it has sold short and returning that security to the entity that lent the security. In addition, on a day-to-day basis, the Fund is expected to hold money market funds, deposit accounts with institutions with high quality credit ratings (i.e. investment grade or higher), and/or short-term debt instruments that have terms-to-maturity of less than 397 days and exhibit high quality credit profiles, including U.S. government securities and repurchase agreements. The Fund seeks to remain fully invested at all times consistent with its stated inverse investment objective, but may not always have inverse exposure to all of the securities in the Index, or its weighting of inverse exposure to securities or industries may be different from that of the Index. In addition, the Fund may have inverse exposure to securities, ETFs or financial instruments not included in the Index. In all cases, the investments would be designed to help the Fund track the Index as it seeks to achieve its inverse leveraged investment objective. The Fund will attempt to achieve its investment objective without regard to overall market movement or the increase or decrease of the value of the securities in the Index. At the close of the markets each trading day, Rafferty rebalances the Fund’s portfolio so that its exposure to the Index is consistent with the Fund’s inverse investment objective. For example, if the Index 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 Index has risen on a given day, net assets of the Fund should fall, meaning the Fund’s exposure will need to be reduced and that a shareholder should lose money, a result that is the opposite of traditional index tracking ETFs. This re-positioning strategy may result in high portfolio turnover. 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,” meaning that a relatively high percentage of its assets may be invested in a limited number of issuers of securities. 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.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 -100% of the return of the Index over the same period.

| Strategy Narrative [Text Block] | The Fund, under normal circumstances, invests at least 80% of the Fund’s net assets (plus borrowings for investment purposes) in financial instruments, including swap agreements and options, that, in combination, provide 1X daily inverse (opposite) or short exposure to AAL, consistent with the Fund’s investment objective.American Airlines Group Inc. is a major airline in the United States headquartered in Fort Worth, Texas. AAL 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 American Airlines Group Inc. pursuant to the Exchange Act can be located by reference to the Securities and Exchange Commission file number 001-8400 through the Securities and Exchange Commission’s website at www.sec.gov. In addition, information regarding American Airlines Group Inc. may be obtained from other sources including, but not limited to, press releases, newspaper articles and other publicly disseminated documents. As of January 31, 2026, AAL is assigned to the industrials sector and the airline industry. The Fund will enter into one or more swap agreements with major global financial institutions whereby the Fund and the global financial institution will agree to exchange the return earned on an investment by the Fund in AAL that is equal, on a daily basis, to -100% of the value of the Fund's net assets. The Adviser attempts to consistently apply leverage to obtain short AAL exposure for the Fund equal to -100% 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 industrials sector and the airline industry (i.e., hold 25% or more of its total assets in investments that provide inverse exposure in the industrials sector and the airline 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 AAL. At the close of the markets each trading day, the Adviser rebalances the Fund’s portfolio so that its exposure to AAL is consistent with the Fund’s investment objective. The impact of AAL’s price movements during the day will affect whether the Fund’s portfolio needs to be rebalanced. For example, if the price of AAL 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 AAL 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. In addition, 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. The Fund has derived all disclosures contained in this document regarding American Airlines Group 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 American Airlines Group 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 AAL have been publicly disclosed. Subsequent disclosure of any such events or the disclosure of, or failure to disclose, material future events concerning American Airlines Group Inc. could affect the value of the Fund’s investments with respect to AAL 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 -100% 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 Narrative [Text Block] | The Fund, under normal circumstances, invests at least 80% of the Fund’s net assets (plus borrowings for investment purposes) in financial instruments, including swap agreements and options, that, in combination, provide 1X daily inverse (opposite) or short exposure to ABNB, consistent with the Fund’s investment objective.Airbnb, Inc. engages in the management and operation of an online marketplace. Its marketplace model connects hosts and guests online or through mobile devices to book spaces. The company was founded in 2007 and is headquartered in San Francisco, CA.. ABNB 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 Airbnb, Inc. pursuant to the Exchange Act can be located by reference to the Securities and Exchange Commission file number 001-39778 through the Securities and Exchange Commission’s website at www.sec.gov. In addition, information regarding Airbnb, Inc. may be obtained from other sources including, but not limited to, press releases, newspaper articles and other publicly disseminated documents. As of January 31, 2026, ABNB is assigned to the consumer discretionary sector and the hotels, restaurants & leisure industry. The Fund will enter into one or more swap agreements with major global financial institutions whereby the Fund and the global financial institution will agree to exchange the return earned on an investment by the Fund in ABNB that is equal, on a daily basis, to -100% of the value of the Fund's net assets. The Adviser attempts to consistently apply leverage to obtain short ABNB exposure for the Fund equal to -100% 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 consumer discretionary sector and the hotels, restaurants & leisure industry (i.e., hold 25% or more of its total assets in investments that provide inverse exposure in the consumer discretionary sector and the hotels, restaurants & leisure 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 ABNB. At the close of the markets each trading day, the Adviser rebalances the Fund’s portfolio so that its exposure to ABNB is consistent with the Fund’s investment objective. The impact of ABNB’s price movements during the day will affect whether the Fund’s portfolio needs to be rebalanced. For example, if the price of ABNB 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 ABNB 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. In addition, 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.

| Strategy Narrative [Text Block] | The Fund, under normal circumstances, invests at least 80% of the Fund’s net assets (plus borrowings for investment purposes) in financial instruments, including swap agreements and options, that, in combination, provide 1X daily inverse (opposite) or short exposure to CAT, consistent with the Fund’s investment objective.Caterpillar Inc. is a construction, mining and other engineering equipment manufacturer founded in 1925. Caterpillar Inc. does business on every continent, principally operating through three primary segments – Construction Industries, Resource Industries and Energy & Transportation – and providing financing and related services through their Financial Products segment. CAT 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 Caterpillar Inc. pursuant to the Exchange Act can be located by reference to the Securities and Exchange Commission file number 001-768 through the Securities and Exchange Commission’s website at www.sec.gov. In addition, information regarding Caterpillar Inc. may be obtained from other sources including, but not limited to, press releases, newspaper articles and other publicly disseminated documents. As of January 31, 2026, CAT is assigned to the industrials sector and the machinery industry. The Fund will enter into one or more swap agreements with major global financial institutions whereby the Fund and the global financial institution will agree to exchange the return earned on an investment by the Fund in CAT that is equal, on a daily basis, to -100% of the value of the Fund's net assets. The Adviser attempts to consistently apply leverage to obtain short CAT exposure for the Fund equal to -100% 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 industrials sector and machinery industry (i.e., hold 25% or more of its total assets in investments that provide inverse exposure in the industrials sector and machinery 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 CAT. At the close of the markets each trading day, the Adviser rebalances the Fund’s portfolio so that its exposure to CAT is consistent with the Fund’s investment objective. The impact of CAT’s price movements during the day will affect whether the Fund’s portfolio needs to be rebalanced. For example, if the price of CAT 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 CAT 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. In addition, 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. The Fund has derived all disclosures contained in this document regarding Caterpillar 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 Caterpillar 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 CAT have been publicly disclosed. Subsequent disclosure of any such events or the disclosure of, or failure to disclose, material future events concerning Caterpillar Inc. could affect the value of the Fund’s investments with respect to CAT 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 -100% 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. |

As of January 31, 2026, COST is assigned to the consumer staples sector. The Fund will enter into one or more swap agreements with major global financial institutions whereby the Fund and the global financial institution will agree to exchange the return earned on an investment by the Fund in COST that is equal, on a daily basis, to -100% of the value of the Fund's net assets. The Adviser attempts to consistently apply leverage to obtain short COST exposure for the Fund equal to -100% 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 consumer staples sector (i.e., hold 25% or more of its total assets in investments that provide inverse exposure in the consumer staples 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 COST. At the close of the markets each trading day, the Adviser rebalances the Fund’s portfolio so that its exposure to COST is consistent with the Fund’s investment objective. The impact of COST’s price movements during the day will affect whether the Fund’s portfolio needs to be rebalanced. For example, if the price of COST 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 COST 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. In addition, 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. The Fund has derived all disclosures contained in this document regarding Costco Wholesale Corporation 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 Costco Wholesale 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 COST have been publicly disclosed. Subsequent disclosure of any such events or the disclosure of, or failure to disclose, material future events concerning Costco Wholesale Corporation could affect the value of the Fund’s investments with respect to COST 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 -100% 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. |

Subsequent disclosure of any such events or the disclosure of, or failure to disclose, material future events concerning DraftKings Inc. could affect the value of the Fund’s investments with respect to DKNG 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 -100% 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 Narrative [Text Block] | The Fund, under normal circumstances, invests at least 80% of the Fund’s net assets (plus borrowings for investment purposes) in financial instruments, including swap agreements and options, that, in combination, provide 1X daily inverse (opposite) or short exposure to GM, consistent with the Fund’s investment objective.General Motors Company engages in the designing, manufacturing, and selling of trucks, crossovers, cars, and automobile parts, and in providing software-enabled services and subscriptions. The company was founded in 1908 and is headquartered in Detroit, MI. GM 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 General Motors Company pursuant to the Exchange Act can be located by reference to the Securities and Exchange Commission file number 001-34960 through the Securities and Exchange Commission’s website at www.sec.gov. In addition, information regarding General Motors Company may be obtained from other sources including, but not limited to, press releases, newspaper articles and other publicly disseminated documents. As of January 31, 2026, GM is assigned to the consumer discretionary sector and automobiles industry. The Fund will enter into one or more swap agreements with major global financial institutions whereby the Fund and the global financial institution will agree to exchange the return earned on an investment by the Fund in GM that is equal, on a daily basis, to -100% of the value of the Fund's net assets. The Adviser attempts to consistently apply leverage to obtain short GM exposure for the Fund equal to -100% 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 consumer discretionary sector and automobiles industry (i.e., hold 25% or more of its total assets in investments that provide inverse exposure in the consumer discretionary sector and automobiles 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 GM. At the close of the markets each trading day, the Adviser rebalances the Fund’s portfolio so that its exposure to GM is consistent with the Fund’s investment objective. The impact of GM’s price movements during the day will affect whether the Fund’s portfolio needs to be rebalanced. For example, if the price of GM 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 GM 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. In addition, 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.

| Strategy Narrative [Text Block] | The Fund, under normal circumstances, invests at least 80% of the Fund’s net assets (plus borrowings for investment purposes) in financial instruments, including swap agreements and options, that, in combination, provide 1X daily inverse (opposite) or short exposure to LCID, consistent with the Fund’s investment objective.Lucid Group, Inc. manufactures electric vehicles. It designs, develops, and builds energy storage systems for electric vehicles and supplies automakers with the battery pack system needed to power hybrid, plug-in, and electric vehicles. The company was founded in December 2007 and is headquartered in Newark, California. LCID 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 Lucid Group, Inc. pursuant to the Exchange Act can be located by reference to the Securities and Exchange Commission file number 001-39408 through the Securities and Exchange Commission’s website at www.sec.gov. In addition, information regarding Lucid Group, Inc. may be obtained from other sources including, but not limited to, press releases, newspaper articles and other publicly disseminated documents. As of January 31, 2026, LCID is assigned to the consumer discretionary sector and the automotive industry. The Fund will enter into one or more swap agreements with major global financial institutions whereby the Fund and the global financial institution will agree to exchange the return earned on an investment by the Fund in LCID that is equal, on a daily basis, to -100% of the value of the Fund's net assets. The Adviser attempts to consistently apply leverage to obtain short LCID exposure for the Fund equal to -100% 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 consumer discretionary sector and the automotive industry (i.e., hold 25% or more of its total assets in investments that provide inverse exposure in the consumer discretionary sector and the automotive 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 LCID. At the close of the markets each trading day, the Adviser rebalances the Fund’s portfolio so that its exposure to LCID is consistent with the Fund’s investment objective. The impact of LCID’s price movements during the day will affect whether the Fund’s portfolio needs to be rebalanced. For example, if the price of LCID 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 LCID 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. In addition, 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. The Fund has derived all disclosures contained in this document regarding Lucid Group, 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 Lucid Group, 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 LCID have been publicly disclosed. Subsequent disclosure of any such events or the disclosure of, or failure to disclose, material future events concerning Lucid Group, Inc. could affect the value of the Fund’s investments with respect to LCID 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 -100% 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. |

Information provided to or filed with the Securities and Exchange Commission by NIKE, Inc. pursuant to the Exchange Act can be located by reference to the Securities and Exchange Commission file number 001-10635 through the Securities and Exchange Commission’s website at www.sec.gov. In addition, information regarding NIKE, Inc. may be obtained from other sources including, but not limited to, press releases, newspaper articles and other publicly disseminated documents. As of January 31, 2026, NKE is assigned to the consumer discretionary sector and textiles, apparel & luxury goods industry. The Fund will enter into one or more swap agreements with major global financial institutions whereby the Fund and the global financial institution will agree to exchange the return earned on an investment by the Fund in NKE that is equal, on a daily basis, to -100% of the value of the Fund's net assets. The Adviser attempts to consistently apply leverage to obtain short NKE exposure for the Fund equal to -100% 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 consumer discretionary sector and textiles, apparel & luxury goods industry (i.e., hold 25% or more of its total assets in investments that provide inverse exposure in the consumer discretionary sector and textiles, apparel & luxury goods 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 NKE. At the close of the markets each trading day, the Adviser rebalances the Fund’s portfolio so that its exposure to NKE is consistent with the Fund’s investment objective. The impact of NKE’s price movements during the day will affect whether the Fund’s portfolio needs to be rebalanced. For example, if the price of NKE 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 NKE 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. In addition, 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. The Fund has derived all disclosures contained in this document regarding NIKE, 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 NIKE, 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 NKE have been publicly disclosed. Subsequent disclosure of any such events or the disclosure of, or failure to disclose, material future events concerning NIKE, Inc. could affect the value of the Fund’s investments with respect to NKE 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 -100% 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. |

As a result of its investment strategies, the Fund will be concentrated in the communication services sector and interactive media & services industry (i.e., hold 25% or more of its total assets in investments that provide inverse exposure in 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 RDDT. At the close of the markets each trading day, the Adviser rebalances the Fund’s portfolio so that its exposure to RDDT is consistent with the Fund’s investment objective. The impact of RDDT’s price movements during the day will affect whether the Fund’s portfolio needs to be rebalanced. For example, if the price of RDDT 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 RDDT 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. In addition, 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.

| Strategy Narrative [Text Block] | The Fund, under normal circumstances, invests at least 80% of the Fund’s net assets (plus borrowings for investment purposes) in financial instruments, including swap agreements and options, that, in combination, provide 1X daily inverse (opposite) or short exposure to SONY, consistent with the Fund’s investment objective.Sony Group Corporation engages in the development, design, manufacture, and sale of electronic equipment, instruments, devices, game consoles, and software for consumers, professionals and industrial markets. The company was founded in 1946 and is headquartered in Tokyo, Japan. SONY 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 Sony Group Corporation pursuant to the Exchange Act can be located by reference to the Securities and Exchange Commission file number 001-06439 through the Securities and Exchange Commission’s website at www.sec.gov. In addition, information regarding Sony Group Corporation may be obtained from other sources including, but not limited to, press releases, newspaper articles and other publicly disseminated documents. As of January 31, 2026, SONY is assigned to the consumer discretionary sector and household durables industry. SONY is a Japanese-based company and is traded as an American Depositary Receipt ("ADR") in the United States. The Fund will enter into one or more swap agreements with major global financial institutions whereby the Fund and the global financial institution will agree to exchange the return earned on an investment by the Fund in SONY that is equal, on a daily basis, to -100% of the value of the Fund's net assets. The Adviser attempts to consistently apply leverage to obtain short SONY exposure for the Fund equal to -100% 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 consumer discretionary sector and household durables industry (i.e., hold 25% or more of its total assets in investments that provide inverse exposure in the consumer discretionary sector and household durables 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 SONY. At the close of the markets each trading day, the Adviser rebalances the Fund’s portfolio so that its exposure to SONY is consistent with the Fund’s investment objective. The impact of SONY’s price movements during the day will affect whether the Fund’s portfolio needs to be rebalanced. For example, if the price of SONY 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 SONY 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. In addition, 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. The Fund has derived all disclosures contained in this document regarding Sony Group Corporation 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 Sony Group 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 SONY have been publicly disclosed. Subsequent disclosure of any such events or the disclosure of, or failure to disclose, material future events concerning Sony Group Corporation could affect the value of the Fund’s investments with respect to SONY 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 -100% 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. |

As a result of its investment strategies, the Fund will be concentrated in the industrials sector and the transportation industry (i.e., hold 25% or more of its total assets in investments that provide inverse exposure in the industrials sector and the transportation 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 UBER. At the close of the markets each trading day, the Adviser rebalances the Fund’s portfolio so that its exposure to UBER is consistent with the Fund’s investment objective. The impact of UBER’s price movements during the day will affect whether the Fund’s portfolio needs to be rebalanced. For example, if the price of UBER 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 UBER 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. In addition, 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. The Fund has derived all disclosures contained in this document regarding Uber Technologies 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 Uber Technologies 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 UBER have been publicly disclosed. Subsequent disclosure of any such events or the disclosure of, or failure to disclose, material future events concerning Uber Technologies Inc. could affect the value of the Fund’s investments with respect to UBER 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 -100% 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 Narrative [Text Block] | The Index consists of the top five securities in the S&P 500 Communication Services (Sector) Index, which includes U.S.-listed companies in the communication services industry as classified by Global Industry Classification Standards (GICS). S&P Dow Jones Indices (the “Index Provider”) selects the top five securities of the S&P 500 Communication Services (Sector) Index, based on each security’s floating market capitalization The Index is equal weighted, meaning that at each rebalancing of the Index, the same exposure is provided to each security included in the Index. The Index is rebalanced quarterly and reconstituted annually. The Index has not yet commenced operations as of the date of this Prospectus.The components of the Index and the percentages represented by various sectors in the Index may change over time. The Fund will concentrate its investment in a particular industry or group of industries (i.e., hold 25% or more of its total assets in the stocks of a particular industry or group of industries) to approximately the same extent as the Index is so concentrated.The Fund, under normal circumstances, invests at least 80% of its net assets (plus borrowing for investment purposes) in financial instruments, securities of the Index, and exchange-traded funds ("ETFs") that track the Index, that, in combination, provide 2X daily leveraged exposure to the Index, consistent with the Fund's investment objective. The financial instruments in which the Fund most commonly invests are swap agreements and futures agreements which are intended to produce economically leveraged investment results.The Fund may invest in the securities of the Index, a representative sample of the securities in the Index that has aggregate characteristics similar to those of the Index, an ETF that tracks the Index or a substantially similar index, and derivatives, such as swaps or futures on the Index or on an ETF that tracks the same Index or a substantially similar index, that provide leveraged exposure to the above. The Fund seeks to remain fully invested at all times, consistent with its stated investment objective, but may not always have investment exposure to all of the securities in the Index, or its weighting of investment exposure to securities or industries may be different from that of the Index. In addition, the Fund may invest directly or indirectly in securities not included in the Index. In all cases, the investments would be designed to help the Fund obtain exposure to the Index to achieve its leveraged investment objective. The Fund will attempt to achieve its investment objective without regard to overall market movement or the increase or decrease of the value of the securities in the Index. At the close of the markets each trading day, Rafferty rebalances the Fund’s portfolio so that its exposure to the Index is consistent with the Fund’s investment objective. The impact of the Index’s movements during the day will affect whether the Fund’s portfolio needs to be re-positioned. For example, if the Index 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 Index has fallen on a given day, net assets of the Fund should fall, meaning the Fund’s exposure will need to be reduced. This re-positioning strategy typically results in high portfolio turnover. In addition, on a day-to-day basis, the Fund is expected to hold money market funds, deposit accounts with institutions with high quality credit ratings (i.e., investment grade or higher), and/or short-term debt instruments that have terms-to-maturity of less than 397 days and exhibit high quality credit profiles, including U.S. government securities and repurchase agreements. The Fund may lend securities representing up to one-third of the value of the Fund’s total assets (excluding the value of the collateral received). 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,” meaning that a relatively high percentage of its assets may be invested in a limited number of issuers of securities. 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.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 Index over the same period. The Fund will lose money if the Index performance is flat over time, and as a result of daily rebalancing, the Index’s volatility and the effects of compounding, it is even possible that the Fund will lose money over time while the Index’s performance increases over a period longer than a single day. |

The Fund invests in derivatives as a substitute for directly shorting securities in order to gain inverse leveraged exposure to the Index or its components. When the Fund shorts securities, including the securities of another investment company, it borrows shares of that security or investment company, which it then sells. The Fund closes out a short sale by purchasing the security that it has sold short and returning that security to the entity that lent the security. In addition, on a day-to-day basis, the Fund is expected to hold money market funds, deposit accounts with institutions with high quality credit ratings (i.e. investment grade or higher), and/or short-term debt instruments that have terms-to-maturity of less than 397 days and exhibit high quality credit profiles, including U.S. government securities and repurchase agreements.

The Index is equal weighted, meaning that at each rebalancing of the Index, the same exposure is provided to each security included in the Index. The Index is rebalanced quarterly and reconstituted annually. The Index has not yet commenced operations as of the date of this Prospectus.The Fund, under normal circumstances, invests at least 80% of the Fund’s net assets (plus borrowing for investment purposes) in financial instruments, including swap agreements, futures contracts, or short positions, that, in combination, provide 2X daily inverse (opposite) or short exposure to the Index or to exchange-traded funds ("ETFs") that track the Index, consistent with the Fund’s investment objective. The financial instruments in which the Fund most commonly invests are swap agreements and futures agreements which are intended to produce economically inverse leveraged investment results.The components of the Index and the percentages represented by various sectors in the Index may change over time. The Fund will concentrate its investment in a particular industry or group of industries (i.e., hold 25% or more of its total assets in investments that provide inverse leveraged exposure to a particular industry or group of industries) to approximately the same extent as the Index is so concentrated.The Fund may also gain inverse leveraged exposure by investing in a combination of financial instruments, such as swap agreements or futures agreements that provide short exposure to the Index, to a representative sample of the securities in the Index that has aggregate characteristics similar to those of the Index or to an ETF that tracks the same Index or a substantially similar index, or the Fund may short securities of the Index, or short an ETF that tracks the same Index or a substantially similar index. The Fund invests in derivatives as a substitute for directly shorting securities in order to gain inverse leveraged exposure to the Index or its components. When the Fund shorts securities, including the securities of another investment company, it borrows shares of that security or investment company, which it then sells. The Fund closes out a short sale by purchasing the security that it has sold short and returning that security to the entity that lent the security. In addition, on a day-to-day basis, the Fund is expected to hold money market funds, deposit accounts with institutions with high quality credit ratings (i.e. investment grade or higher), and/or short-term debt instruments that have terms-to-maturity of less than 397 days and exhibit high quality credit profiles, including U.S. government securities and repurchase agreements. The Fund seeks to remain fully invested at all times consistent with its stated inverse leveraged investment objective, but may not always have inverse exposure to all of the securities in the Index, or its weighting of inverse exposure to securities or industries may be different from that of the Index. In addition, the Fund may have inverse exposure to securities, ETFs or financial instruments not included in the Index. In all cases, the investments would be designed to help the Fund track the Index as it seeks to achieve its inverse leveraged investment objective. The Fund will attempt to achieve its investment objective without regard to overall market movement or the increase or decrease of the value of the securities in the Index. At the close of the markets each trading day, Rafferty rebalances the Fund’s portfolio so that its exposure to the Index is consistent with the Fund’s inverse leveraged investment objective. For example, if the Index 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 Index has risen on a given day, net assets of the Fund should fall, meaning the Fund’s exposure will need to be reduced and that a shareholder should lose money, a result that is the opposite of traditional index tracking ETFs. This re-positioning strategy may result in high portfolio turnover. 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,” meaning that a relatively high percentage of its assets may be invested in a limited number of issuers of securities. 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.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 Index over the same period. The Fund will lose money if the Index performance is flat over time, and as a result of daily rebalancing, the Index’s volatility and the effects of compounding, it is even possible that the Fund will lose money over time while the Index’s performance decreases over a period longer than a single day. |

For example, if the Index 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 Index has risen on a given day, net assets of the Fund should fall, meaning the Fund’s exposure will need to be reduced and that a shareholder should lose money, a result that is the opposite of traditional index tracking ETFs. This re-positioning strategy may result in high portfolio turnover. 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,” meaning that a relatively high percentage of its assets may be invested in a limited number of issuers of securities. 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.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 Index over the same period. The Fund will lose money if the Index performance is flat over time, and as a result of daily rebalancing, the Index’s volatility and the effects of compounding, it is even possible that the Fund will lose money over time while the Index’s performance decreases over a period longer than a single day. |

The Fund invests in derivatives as a substitute for directly shorting securities in order to gain inverse leveraged exposure to the Index or its components. When the Fund shorts securities, including the securities of another investment company, it borrows shares of that security or investment company, which it then sells. The Fund closes out a short sale by purchasing the security that it has sold short and returning that security to the entity that lent the security.

| Strategy Narrative [Text Block] | The Index is designed by Solactive AG (the "Index Provider") to represent the securities of the next generation of U.S. companies that utilize quantum technology to improve the provision of their products and/or services. Quantum technology is a class of technology that use the principles of quantum mechanics (the physics of sub-atomic particles) to make advances in computing and other processes. The Index is a rules-based index and includes U.S.-listed securities of companies in the following quantum technology segments (each, a “Quantum Technology Segment”): ●Quantum Computing Infrastructure and Hardware: This segment encompasses companies that develop and provide the essential physical components, systems, and comprehensive environments necessary for quantum computing, including both hardware and infrastructure services. ●Quantum AI and Machine Learning: This segment focuses on companies that integrate artificial intelligence and machine learning with quantum computing to enhance problem-solving and algorithm efficiency. ●Quantum Software and Applications: Within this segment, companies are dedicated to create software tools and applications to operate quantum computers and utilize their computational power for various specialized tasks. ●Quantum AI and Cryptography: This segment addresses companies that develop quantum-based security mechanisms and engage in advanced research and development to push the boundaries of quantum technologies. To be selected for inclusion in the Index, a security must have a free float market capitalization of at least $100 million (or at least $90 billion for current constituents) and a minimum average daily traded value of at least $1 million over 1 month and over 6 months (or at least $900,000 for current constituents). To identify companies that use quantum technology, the Index Provider uses ARTIS®, its proprietary natural language processing algorithm, to identify into which Quantum Technology Segment(s) a company falls. ARTIS uses keywords to review large volumes of publicly available data, such as company annual reports, published business descriptions, and financial news reports, which the Index Provider believes will identify and classify companies as quantum technology companies, and then ranks the companies based on the number of keyword “hits” in the company’s data. The ARTIS classification system is different than traditional classification systems because it utilizes natural language processing, such as keyword searching, whereas traditional classifications system utilize backward looking metrics, such as a company’s past profits or revenue, to determine the classification of a company. ARTIS produces a score for each company that reflects the company's exposure to quantum technology and considers each Quantum Technology Segment to which a company belongs. Each company is then ranked by its score, and the top 20 companies are selected for inclusion in the Index. The Index is rebalanced semi-annually. As of January 30, 2026, the Index included 20 constituents and were concentrated in the information technology sector with exposure to quantum technology.The Fund will concentrate its investment in a particular industry or group of industries (i.e., hold 25% or more of its total assets in the stocks of a particular industry or group of industries) to approximately the same extent as the Index is so concentrated.The Fund, under normal circumstances, invests at least 80% of its net assets (plus borrowing for investment purposes) in financial instruments, securities of the Index, and exchange-traded funds ("ETFs") that track the Index, that, in combination, provide 2X daily leveraged exposure to the Index, consistent with the Fund's 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 the securities of TOPT and financial instruments, such as swap agreements and options, that, in combination, provide 2X daily leveraged exposure to TOPT, consistent with the Fund’s investment objective. The financial instrument in which the Fund most commonly invests is swap agreements, which are intended to produce economically leveraged investment results.TOPT seeks to track the investment results of the S&P 500 Top 20 Select Index (the “S&P Index”), which measures the performance of the 20 largest U.S. companies by float-adjusted market capitalization within the S&P 500® as determined by S&P Dow Jones Indices LLC. The securities in the S&P Index are weighted based on the float-adjusted market value of their outstanding shares subject to capping. For capping purposes, the S&P Index will be rebalanced on a quarterly basis. At each quarterly rebalance in March, June, September, and December, the weight of any single issuer will not exceed 22.5% of the S&P Index; and the aggregate weight of issuers with individual weights exceeding 4.5% will not exceed 48% of the S&P Index. Between rebalances, constituent weights may exceed these constraints due to fluctuations in market value, corporate actions, or other events that change the index composition. TOPT 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 iShares Trust pursuant to the Exchange Act can be located by reference to the Securities and Exchange Commission file number 333-92935 through the Securities and Exchange Commission’s website at www.sec.gov. In addition, information regarding TOPT may be obtained from other sources including, but not limited to, press releases, newspaper articles and other publicly disseminated documents. The Fund will enter into one or more swap agreements with major global financial institutions whereby the Fund and the global financial institution will agree to exchange the return earned on an investment by the Fund in TOPT that is equal, on a daily basis, to 200% of the value of the Fund's net assets. The Adviser attempts to consistently apply leverage to obtain TOPT 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 information technology sector (i.e., hold 25% or more of its total assets in investments that provide leveraged exposure in the information technology 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 TOPT. At the close of the markets each trading day, the Adviser rebalances the Fund’s portfolio so that its exposure to TOPT is consistent with the Fund’s investment objective. The impact of TOPT’s price movements during the day will affect whether the Fund’s portfolio needs to be rebalanced. For example, if the price of TOPT 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 TOPT 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. In addition, 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 Fund may lend securities representing up to one-third of the value of the Fund’s total assets (excluding the value of the collateral received). 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 has derived all disclosures contained in this document regarding iShares Top 20 U.S. Stocks ETF 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 iShares Top 20 U.S. Stocks ETF 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 TOPT have been publicly disclosed. Subsequent disclosure of any such events or the disclosure of, or failure to disclose, material future events concerning iShares Top 20 U.S. Stocks ETF could affect the value of the Fund’s investments with respect to TOPT 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 ETF over the same period. The Fund will lose money if the underlying ETF performance is flat over time, and as a result of daily rebalancing, the underlying ETF’s volatility and the effects of compounding, it is even possible that the Fund will lose money over time while the underlying ETF’s performance increases over a period longer than a single day. |

| Strategy Narrative [Text Block] | The Fund, under normal circumstances, invests at least 80% of its net assets (plus any borrowings for investment purposes) in the securities of QTOP and financial instruments, such as swap agreements and options, that, in combination, provide 2X daily leveraged exposure to QTOP, consistent with the Fund’s investment objective. The financial instrument in which the Fund most commonly invests is swap agreements, which are intended to produce economically leveraged investment results.QTOP seeks to track the investment results of the Nasdaq-100 Top 30 Index (the “Nasdaq Index”), which measures the performance of securities of the 30 largest domestic and international non-financial companies listed on Nasdaq (on the Nasdaq Global Select Market or the Nasdaq Global Market) based on market capitalization, as determined by Nasdaq, Inc. The Nasdaq Index is a subset of the Nasdaq-100 Index. The securities in the Nasdaq Index are weighted based on the market value of their outstanding shares subject to capping. The Nasdaq Index is reconstituted and rebalanced quarterly in March, June, September, and December. For capping purposes, at each quarterly rebalance, the weight of any single issuer will not exceed 22.5% of the Nasdaq Index; and the aggregate weight of issuers with individual weights exceeding 4.5% will not exceed 48% of the Nasdaq Index. Between rebalances, constituent weights may exceed these constraints due to fluctuations in market value, corporate actions, or other events that change the index composition. QTOP 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 iShares Trust pursuant to the Exchange Act can be located by reference to the Securities and Exchange Commission file number 333-92935 through the Securities and Exchange Commission’s website at www.sec.gov. In addition, information regarding QTOP may be obtained from other sources including, but not limited to, press releases, newspaper articles and other publicly disseminated documents. The Fund will enter into one or more swap agreements with major global financial institutions whereby the Fund and the global financial institution will agree to exchange the return earned on an investment by the Fund in QTOP that is equal, on a daily basis, to 200% of the value of the Fund's net assets. The Adviser attempts to consistently apply leverage to obtain QTOP 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 information technology sector (i.e., hold 25% or more of its total assets in investments that provide leveraged exposure in the information technology 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 QTOP. At the close of the markets each trading day, the Adviser rebalances the Fund’s portfolio so that its exposure to QTOP is consistent with the Fund’s investment objective. The impact of QTOP’s price movements during the day will affect whether the Fund’s portfolio needs to be rebalanced. For example, if the price of QTOP 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 QTOP 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. In addition, 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 Fund may lend securities representing up to one-third of the value of the Fund’s total assets (excluding the value of the collateral received). 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 has derived all disclosures contained in this document regarding iShares Nasdaq Top 30 ETF 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 iShares Nasdaq Top 30 ETF 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 QTOP have been publicly disclosed. Subsequent disclosure of any such events or the disclosure of, or failure to disclose, material future events concerning iShares Nasdaq Top 30 ETF could affect the value of the Fund’s investments with respect to QTOP 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 ETF over the same period. The Fund will lose money if the underlying ETF performance is flat over time, and as a result of daily rebalancing, the underlying ETF’s volatility and the effects of compounding, it is even possible that the Fund will lose money over time while the underlying ETF’s performance increases over a period longer than a single day. |

CCL was founded in 1972 and is headquartered in Miami, Florida. CCL 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 Carnival Corporation pursuant to the Exchange Act can be located by reference to the Securities and Exchange Commission file number 001-9610 through the Securities and Exchange Commission’s website at www.sec.gov. In addition, information regarding Carnival Corporation may be obtained from other sources including, but not limited to, press releases, newspaper articles and other publicly disseminated documents. As of January 31, 2026, CCL is assigned to the consumer discretionary sector and the hotels, restaurants & leisure industry. The Fund will enter into one or more swap agreements with major global financial institutions whereby the Fund and the global financial institution will agree to exchange the return earned on an investment by the Fund in CCL that is equal, on a daily basis, to 200% of the value of the Fund's net assets. The Adviser attempts to consistently apply leverage to obtain CCL 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 consumer discretionary sector and the hotel, restaurants & leisure industry (i.e., hold 25% or more of its total assets in investments that provide leveraged exposure in the consumer discretionary sector and the hotel, restaurants & leisure 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 CCL. At the close of the markets each trading day, the Adviser rebalances the Fund’s portfolio so that its exposure to CCL is consistent with the Fund’s investment objective. The impact of CCL’s price movements during the day will affect whether the Fund’s portfolio needs to be rebalanced. For example, if the price of CCL 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 CCL 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. In addition, 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 Fund may lend securities representing up to one-third of the value of the Fund’s total assets (including the value of the collateral received).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 has derived all disclosures contained in this document regarding Carnival Corporation 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 Carnival 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 CCL have been publicly disclosed. Subsequent disclosure of any such events or the disclosure of, or failure to disclose, material future events concerning Carnival Corporation could affect the value of the Fund’s investments with respect to CCL 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. |

In addition, 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 Fund may lend securities representing up to one-third of the value of the Fund’s total assets (including the value of the collateral received). 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.

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 Delta Air Lines, 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 DAL have been publicly disclosed. Subsequent disclosure of any such events or the disclosure of, or failure to disclose, material future events concerning Delta Air Lines, Inc. could affect the value of the Fund’s investments with respect to DAL 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 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 financial instrument in which the Fund most commonly invests is swap agreements, which are intended to produce economically leveraged investment results.Lucid Group, Inc. manufactures electric vehicles. It designs, develops, and builds energy storage systems for electric vehicles and supplies automakers with the battery pack system needed to power hybrid, plug-in, and electric vehicles. The company was founded in December 2007 and is headquartered in Newark, California. LCID 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 Lucid Group, Inc. pursuant to the Exchange Act can be located by reference to the Securities and Exchange Commission file number 001-39408 through the Securities and Exchange Commission’s website at www.sec.gov. In addition, information regarding Lucid Group, Inc. may be obtained from other sources including, but not limited to, press releases, newspaper articles and other publicly disseminated documents. As of January 31, 2026, LCID is assigned to the consumer discretionary sector and automotive industry. The Fund will enter into one or more swap agreements with major global financial institutions whereby the Fund and the global financial institution will agree to exchange the return earned on an investment by the Fund in LCID that is equal, on a daily basis, to 200% of the value of the Fund's net assets. The Adviser attempts to consistently apply leverage to obtain LCID 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 consumer discretionary sector and the automotive industry (i.e., hold 25% or more of its total assets in investments that provide leveraged exposure in the consumer discretionary sector and the automotive 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 LCID. At the close of the markets each trading day, the Adviser rebalances the Fund’s portfolio so that its exposure to LCID is consistent with the Fund’s investment objective. The impact of LCID’s price movements during the day will affect whether the Fund’s portfolio needs to be rebalanced. For example, if the price of LCID 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 LCID 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. In addition, 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.

| Strategy Narrative [Text Block] | The Fund, under normal circumstances, invests at least 80% of its net assets (plus any borrowings for investment purposes) in the securities of O and financial instruments, such as swap agreements and options, that, in combination, provide 2X daily leveraged exposure to O, consistent with the Fund’s investment objective. The financial instrument in which the Fund most commonly invests is swap agreements, which are intended to produce economically leveraged investment results.Realty Income Corporation is a real estate company, which engages in generating dependable monthly cash dividends from a consistent and predictable level of cash flow from operations. The company was founded in 1969 and is headquartered in San Diego, California. O 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 Realty Income Corporation pursuant to the Exchange Act can be located by reference to the Securities and Exchange Commission file number 001-13374 through the Securities and Exchange Commission’s website at www.sec.gov. In addition, information regarding Realty Income Corporation may be obtained from other sources including, but not limited to, press releases, newspaper articles and other publicly disseminated documents. As of January 31, 2026, O is assigned to the real estate sector. The Fund will enter into one or more swap agreements with major global financial institutions whereby the Fund and the global financial institution will agree to exchange the return earned on an investment by the Fund in O that is equal, on a daily basis, to 200% of the value of the Fund's net assets. The Adviser attempts to consistently apply leverage to obtain O 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 real estate sector (i.e., hold 25% or more of its total assets in investments that provide leveraged exposure in the real estate 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 O. At the close of the markets each trading day, the Adviser rebalances the Fund’s portfolio so that its exposure to O is consistent with the Fund’s investment objective. The impact of O’s price movements during the day will affect whether the Fund’s portfolio needs to be rebalanced. For example, if the price of O 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 O 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. In addition, 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 Fund may lend securities representing up to one-third of the value of the Fund’s total assets (including the value of the collateral received).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 has derived all disclosures contained in this document regarding Realty Income Corporation 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 Realty Income 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 O have been publicly disclosed. Subsequent disclosure of any such events or the disclosure of, or failure to disclose, material future events concerning Realty Income Corporation could affect the value of the Fund’s investments with respect to O 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. |

| Strategy Narrative [Text Block] | The Fund, under normal circumstances, invests at least 80% of its net assets (plus any borrowings for investment purposes) in the securities of RKLB and financial instruments, such as swap agreements and options, that, in combination, provide 2X daily leveraged exposure to RKLB, consistent with the Fund’s investment objective. The financial instrument in which the Fund most commonly invests is swap agreements, which are intended to produce economically leveraged investment results.Rocket Lab USA, Inc. is an aerospace company, which engages in the development of rocket launch and control systems for the space and defense industries. The company was founded in 2006 and is headquartered in Long Beach, CA. RKLB 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 Rocket Lab USA, Inc. pursuant to the Exchange Act can be located by reference to the Securities and Exchange Commission file number 001-39560 through the Securities and Exchange Commission’s website at www.sec.gov. In addition, information regarding Rocket Lab USA, Inc. may be obtained from other sources including, but not limited to, press releases, newspaper articles and other publicly disseminated documents. As of January 31, 2026, RKLB is assigned to the industrials sector and aerospace & defense industry. The Fund will enter into one or more swap agreements with major global financial institutions whereby the Fund and the global financial institution will agree to exchange the return earned on an investment by the Fund in RKLB that is equal, on a daily basis, to 200% of the value of the Fund's net assets. The Adviser attempts to consistently apply leverage to obtain RKLB 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 industrials sector and aerospace & defense industry (i.e., hold 25% or more of its total assets in investments that provide leveraged exposure in the industrials sector and aerospace & defense 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 RKLB. At the close of the markets each trading day, the Adviser rebalances the Fund’s portfolio so that its exposure to RKLB is consistent with the Fund’s investment objective. The impact of RKLB’s price movements during the day will affect whether the Fund’s portfolio needs to be rebalanced. For example, if the price of RKLB 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 RKLB 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. In addition, 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 Fund may lend securities representing up to one-third of the value of the Fund’s total assets (including the value of the collateral received). 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 has derived all disclosures contained in this document regarding Rocket Lab USA, 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 Rocket Lab USA, 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 RKLB have been publicly disclosed. Subsequent disclosure of any such events or the disclosure of, or failure to disclose, material future events concerning Rocket Lab USA, Inc. could affect the value of the Fund’s investments with respect to RKLB 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. |

In addition, 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 Fund may lend securities representing up to one-third of the value of the Fund’s total assets (including the value of the collateral received). 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 has derived all disclosures contained in this document regarding United Airlines 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 United Airlines 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 UAL have been publicly disclosed. Subsequent disclosure of any such events or the disclosure of, or failure to disclose, material future events concerning United Airlines Holdings, Inc. could affect the value of the Fund’s investments with respect to UAL 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 financial instrument in which the Fund most commonly invests is swap agreements, which are intended to produce economically leveraged investment results.Uber Technologies, Inc. is a technology platform, which engages in the development and operation of technology applications, networks, and product to power movement from point A to point B. The firm offers ride services and merchants delivery service in 2009 and is headquartered in San Francisco, California. UBER 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 Broadcom Inc. pursuant to the Exchange Act can be located by reference to the Securities and Exchange Commission file number 001-38902 through the Securities and Exchange Commission’s website at www.sec.gov. In addition, information regarding Uber Technologies, Inc. may be obtained from other sources including, but not limited to, press releases, newspaper articles and other publicly disseminated documents. As of January 31, 2026, UBER is assigned to the industrials sector and transportation industry. The Fund will enter into one or more swap agreements with major global financial institutions whereby the Fund and the global financial institution will agree to exchange the return earned on an investment by the Fund in UBER that is equal, on a daily basis, to 200% of the value of the Fund's net assets. The Adviser attempts to consistently apply leverage to obtain UBER 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 industrials sector and the transportation industry (i.e., hold 25% or more of its total assets in investments that provide leveraged exposure in the industrials sector and the transportation 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 UBER. At the close of the markets each trading day, the Adviser rebalances the Fund’s portfolio so that its exposure to UBER is consistent with the Fund’s investment objective. The impact of UBER’s price movements during the day will affect whether the Fund’s portfolio needs to be rebalanced. For example, if the price of UBER 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 UBER has fallen on a given day, net assets of the Fund should fall, meaning the Fund’s exposure will need to be reduced.
