Strategy [Heading]	<span style="color:#000000;font-family:Arial;font-size:9.025pt;font-weight:bold;">Principal Investment Strategy</span>
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 SKHY and financial instruments, such as swap agreements and options, that, in combination, provide 2X daily leveraged exposure to SKHY, 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.SK hynix Inc. (“SK hynix”) is a South Korean global semiconductor company that engages in the manufacture and sale of semiconductor devices. The core products of the company are memory semiconductors, including dynamic random-access memory (“DRAM”) and NAND Flash memory. SK hynix also operates a foundry business. After completion of the issuance of its American depository shares, SK hynix will be 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 SK hynix Inc. pursuant to the Exchange Act can be located by reference to the Securities and Exchange Commission file number 333-296987 through the Securities and Exchange Commission’s website at www.sec.gov. SK hynix only recently issued its American depository shares. Consequently, public information filed with the Securities and Exchange Commission is limited. In addition, information regarding SK hynix Inc. may be obtained from other sources including, but not limited to, SK hynix's website (www.skhynix.com), press releases, newspaper articles and other publicly disseminated documents. As of the date of this Prospectus, SK hynix is assigned to the information technology sector and the semiconductor industry, which includes exposure to artificial intelligence. As of the date of this Prospectus, the market capitalization of SK Hynix is over $1 trillion USD. 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 SKHY 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 SKHY 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 and semiconductor industry (i.e., hold 25% or more of its total assets in investments that provide leveraged exposure in the information technology sector and semiconductor 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 SKHY. At the close of the markets each trading day, the Adviser rebalances the Fund’s portfolio so that its exposure to SKHY is consistent with the Fund’s investment objective. The impact of SKHY’s price movements during the day will affect whether the Fund’s portfolio needs to be rebalanced. For example, if the price of SKHY 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 SKHY 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 SK hynix 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 SK hynix 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 SKHY have been publicly disclosed. Subsequent disclosure of any such events or the disclosure of, or failure to disclose, material future events concerning SK hynix Inc. could affect the value of the Fund’s investments with respect to SKHY 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.
