Market Risk. The prices of securities held by the fund may decline in response to market risks. Medium Sized Companies Risk. Medium-sized companies often have less predictable earnings, more limited product lines, markets, distribution channels or financial resources and the management of such companies may be dependent upon one or few key people. The market movements of equity securities of medium-sized companies may be more abrupt and volatile than the market movements of equity securities of larger, more established companies or the stock market in general. Historically, medium-sized companies have sometimes gone through extended periods when they did not perform as well as larger companies. In addition, equity securities of medium-sized companies generally are less liquid than larger companies. This means that the Fund could have greater difficulty selling such securities at the time and price that the Fund would like. Growth Investing Risk. The fund invests in "growth stocks," which may be more volatile than other investment styles because growth stocks are more sensitive to investor perceptions of an issuing company?s growth potential. Foreign Risk. The risks of investing in securities of foreign issuers, including emerging market issuers, can include fluctuations in foreign currencies, foreign currency exchange controls, political and economic instability, differences in securities regulation and trading, and foreign taxation issues. REIT's Risk. REITs are susceptible to risk associated with the ownership of real estate and the real estate industry in general. In addition, REITs depends on specialized management skills, may not be diversified, may have less trading volume and may be subject to more abrupt or erratic price movements than the overall securities market. Investments in REITs may involve duplication of management fees and certain other expenses. Derivatives Risk. The fund may use enhanced investment techniques such as derivatives. The principal risk of derivatives is that the fluctuations in their values may not correlate perfectly with the overall securities markets. Derivatives are subject to counterparty risk—the risk that the other party will not complete the transaction with the fund.
