Funds that, by portfolio practice, invest at least 75% of their equity assets in companies with market capitalizations (on a three-year weighted basis) of less than 300% of the dollar-weighted median market capitalization of the S&P Mid-Cap 400 Index. Mid-Cap Growth funds normally invest in companies with long-term earnings expected to grow significantly faster than the earnings of the stocks represented in a major unmanaged stock index. These funds will normally have an above-average price-to-earnings ratio, price-to-book ratio, and three-year earnings growth figure, compared to the U.S. diversified mid-cap funds universe average.
