This includes companies providing blockchain technology services, including operation of digital asset trading platforms or payment gateways that facilitate payments made with digital assets and companies active in the development or integration of blockchain software and blockchain applications; ? Non-Fungible Tokens (NFT) & Tokenization Companies that enable users to be a part of the digital economy through NFT where each NFT is unique and can be tracked through the blockchain. This includes companies active in NFT trading platform business, or companies having engaged in NFT business by launching NFT auction, issuing NFT or providing NFT brokerage service; ? Decentralized Finance Companies that are engaged in the development or provision of decentralized payment technologies and/or that are involved in the provision of technologies, infrastructure, or hardware used to develop or operate decentralized payment systems; and ? Digital Asset Mining Hardware Companies that are involved in the manufacture, distribution or assembly of cryptocurrency mining equipment. To be eligible for inclusion in the Index, the securities must be listed on the NYSE, NASDAQ, or the NYSE American, have a share class market capitalization of at least $500,000,000, and have an average daily traded value of at least $5,000,000. Once the eligible universe of securities has been identified, companies are selected for inclusion in the Index by the Index Provider, using ARTIS , the Index Providers proprietary natural language processing algorithm. ARTIS uses key words 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 having significant exposure to the provision of products and/or services that contribute to the distributed ledger or decentralized payment technology and then ranks the companies based on the number of key word hits in the companys data. The ARTIS classification system is different than traditional classification systems because it utilizes natural language processing, such as key word searching, and does not utilize backward looking metrics, such as a companys past profits or revenue, to determine the classification of a company. Companies are only eligible for inclusion in the Index if they generate at least 50% of their revenue from Crypto Industry Businesses. The Index consists of at least the top 5 ranked companies and then selects additional securities from the current constituents and newly eligible constituents, with a minimum of 25, from those ranking as most relevant. The index is rebalanced and reconstituted quarterly. As of December 31, 2024, the Index consisted of 25 constituents which were concentrated in the information technology and financial sectors. The Fund does not invest directly in cryptocurrency, non-fungible tokens or any other digital asset. 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.
