Strategy. Under normal circumstances, the Fund invests substantially all (at least 80%) of its net assets in equity securities of Energy Services Companies that are traded in the United States and in derivatives, which primarily consist of futures contracts and options on securities, futures contracts, and stock indices. The Advisor employs a proprietary quantitative and qualitative methodology to identify Energy Services Companies in which to invest. The methodology utilizes screens based on price, liquidity, and tradability. The securities are then weighted using a proprietary modified capitalization weighting methodology.

The Advisor employs a proprietary quantitative and qualitative methodology to identify Energy Services Companies in which to invest. The methodology utilizes screens based on price, liquidity, and tradability. The securities are then weighted using a proprietary modified capitalization weighting methodology. The portfolio may be further adjusted to comply with regulatory investment limitations or as determined appropriate by the Advisor. The Fund may invest to a significant extent in the securities of Energy Services Companies that have small to mid-sized capitalizations. Energy Services Companies are engaged in one or more businesses in the energy services field, including those that provide services and equipment to companies engaged in the production, refinement or distribution of oil, gas, electricity, and coal; companies involved with the production and development of newer sources of energy such as nuclear, geothermal, oil shale, and solar power; companies involved with onshore or offshore drilling; companies involved in production and well maintenance; companies involved in exploration engineering, data and technology; companies involved in energy transport; and companies involved in equipment and plant design or construction. The Fund also may purchase American Depositary Receipts (ADRs) to gain exposure to foreign Energy Services Companies and U.S. government securities. Investments in derivative instruments, such as futures and options, have the economic effect of creating financial leverage in the Funds portfolio because such investments may give rise to losses that exceed the amount the Fund has invested in those instruments. Financial leverage will magnify, sometimes significantly, the Funds exposure to any increase or decrease in prices associated with a particular reference asset resulting in increased volatility in the value of the Funds portfolio. The value of the Funds portfolio is likely to experience greater volatility over short-term periods. While such financial leverage has the potential to produce greater gains, it also may result in greater losses, which in some cases may cause the Fund to liquidate other portfolio investments at a loss to comply with limits on leverage imposed by the Investment Company Act of 1940, satisfy margin or collateral requirements, or meet redemption requests. In an effort to ensure that the Fund is fully invested on a day-to-day basis, the Fund may conduct any necessary trading activity at or just prior to the close of the U.S. financial markets. As of March 31, 2025, the Fund has significant exposure to the Energy Sector, as that sector is defined by the Global Industry Classification Standard, a widely recognized industry classification methodology developed by MSCI, Inc. and Standard & Poor's Financial Services LLC. Also, as of March 31, 2025, the Fund's investments are concentrated (i.e., more than 25% of its assets) in securities issued by companies in the Energy Equipment & Services Industry, a separate industry within the Energy Sector. The Fund is non-diversified and, therefore, may invest a greater percentage of its assets in a particular issuer in comparison to a diversified fund. Show less
