The ETFs and mutual funds in which the Fund may invest are referred to as "underlying funds" throughout this Prospectus. The underlying funds generally invest in equity securities and derivatives. The underlying funds may invest in both domestic and international securities, including securities from emerging markets. The underlying funds may invest in small and medium capitalization companies and derivative instruments such as put and call options on stocks and stock indices, and index futures contracts and options thereon. The underlying funds may use leverage and inverse strategies, including strategies that seek to earn multiples of the returns of a particular segment of the investment market or the markets as a whole. The Fund may invest directly in derivatives, such as futures contracts, and may establish both long and short positions. The Fund expects to rebalance its investments in underlying funds that use leverage and/or inverse strategies on an ongoing basis as market movements dictate and there is no limitation on the amount of the Fund?s assets that may be invested in these types of underlying funds. However, the Fund is subject to limits designed to comply with applicable regulatory requirements, including Rule 18f-4 under the Investment Company Act of 1940. The Fund employs risk management procedures in connection with its derivatives strategies, including monitoring of notional exposure and stress testing. Potomac Fund Management, Inc., the investment advisor to the Fund (the ?Advisor?), utilizes technical analysis based quantitative systems to guide its decision-making process for the Fund. The Advisor?s investment process seeks to identify trends to determine the strength or weakness in the current market environment. This part of the Advisor?s process analyzes over 100 technical trading indicators built through a multitude of programming platforms. Each indicator is rigorously tested on an individual basis to determine the combinations that provide what the Advisor perceives to be the best indication of market direction. The technical trading indicators are then combined into sophisticated algorithmic composites that guide the Advisor?s decision-making process. The Fund will generally use funds that hold a broad-based basket of equity securities. If the Advisor?s algorithmic composites point to a rising market, the Fund will invest in ETFs that provide leveraged exposure of a particular market index, such as the S&P 500 Index. During downward trending markets, the Advisor will attempt to reduce downside exposure by limiting the Fund?s investments to cash and cash equivalents. The Advisor may also invest in fixed income securities with longer maturities. If the trend is, in the Advisor?s view, weak enough the Fund?s assets may be invested in ETFs that provide inverse exposure of a particular market index, such as the S&P 500 Index. The Fund is a ?non-diversified? fund, which means it can invest in fewer securities at any one time than a diversified fund and can invest more of its assets in securities of a single issuer than a diversified fund. Also, the Fund may invest in a limited number of sectors but has no intention to concentrate its investments in any particular industry. The Fund may also engage in short-term trading and have a portfolio turnover rate significantly in excess of 100%. Show less
