Strategy. The Index tracks the performance of domestic and foreign, including developing and emerging, small- and mid-capitalization companies that are involved in the gold and silver mining industry (Junior Gold Miners). The Index Provider, MarketVector Indexes GmbH, defines Junior Gold Miners as those companies that generate at least 50% of their revenues from gold mining/royalties/streaming and/or silver mining/royalties/streaming, or with mining projects that have the potential to generate at least 50% of their revenues from gold mining and/or silver mining. In addition, stocks must meet strict size and liquidity requirements: (1) the full market capitalization has to exceed $150 million in U.S. dollars; (2) the three months average-daily-trading volume must be higher than $1.0 million in U.S. dollars; and (3) the … Show more… The Index tracks the performance of domestic and foreign, including developing and emerging, small- and mid-capitalization companies that are involved in the gold and silver mining industry (Junior Gold Miners).

The Index includes companies from markets that are freely investable to foreign investors, including emerging markets, as that term is defined by the index provider. Each silver mining company will not represent more than 4.5% of the Index and the total weighting of silver mining companies will not constitute more than 20% of the Index, and gold mining companies will not constitute less than 80% of the Index. As of December 31, 2024, the principal suppliers of gold included in the Index were located in twelve countries or territories: Canada, Australia, South Africa, the United Kingdom, the United States, Mexico, China, Indonesia Peru, Turkey, the British Virgin Islands and Jersey. As of December 31, 2024, the Index included 79 constituents which were concentrated in the gold mining industry, which is included in the materials sector. The Index is reviewed semi-annually and rebalanced quarterly. 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, such as swap agreements, 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 track the Index. 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 Funds portfolio so that its exposure to the Index is consistent with the Funds investment objective. The impact of the Indexs movements during the day will affect whether the Funds 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 Funds 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 Funds exposure will need to be reduced. This re-positioning strategy typically results in high portfolio turnover. On a day-to-day basis, the Fund is expected to hold ETFs and 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 Funds 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 Funds investment objective is not a fundamental policy and may be changed by the Funds Board of Trustees without shareholder approval. Because of daily rebalancing and the compounding of each days return over time, the return of the Fund for periods longer than a single day will be the result of each days 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 Indexs volatility and the effects of compounding, it is even possible that the Fund will lose money over time while the Indexs performance increases over a period longer than a single day.
