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 ANET and financial instruments, such as swap agreements and options, that, in combination, provide 2X daily leveraged exposure to ANET, 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.Arista Networks, Inc. is a cloud networking company that designs and delivers data-driven networking solutions for large data center, cloud, enterprise, and artificial intelligence environments. Arista Networks, Inc. is headquartered in Santa Clara, California. ANET is registered under the Securities Exchange Act of 1934, as amended (the “Exchange Act”).

In addition, information regarding Arista Networks, Inc. may be obtained from other sources including, but not limited to, press releases, newspaper articles, and other publicly disseminated documents. As of June 30, 2026, ANET is assigned to the information technology sector and communications equipment industry, which includes exposure to artificial intelligence.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 ANET 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 ANET 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 communications equipment industry (i.e., hold 25% or more of its total assets in investments that provide leveraged exposure in the information technology sector and communications equipment industry).The Fund will attempt to achieve its investment objective without regard to overall market movement or the increase or decrease of the value of ANET. At the close of the markets each trading day, the Adviser rebalances the Fund’s portfolio so that its exposure to ANET is consistent with the Fund’s investment objective. The impact of ANET’s price movements during the day will affect whether the Fund’s portfolio needs to be rebalanced. For example, if the price of ANET 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 ANET 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 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.
