The fund will normally invest at least 80% of its net assets (including any borrowings for investment purposes) in a diversified portfolio of common stocks of mid-cap companies whose earnings T. Rowe Price expects to grow at a faster rate than the average company. The fund defines mid-cap companies as those whose market capitalization (number of shares outstanding multiplied by share price) falls within the range of either the S&P MidCap 400® Index or the Russell Midcap® Growth Index. As of December 31, 2019, the market capitalization ranges for the S&P MidCap 400® Index and the Russell Midcap® Growth Index were approximately $1.1 billion to $19.4 billion, and $1.2 billion to $78.6 billion, respectively. The market capitalization of the companies in the fund’s portfolio and the S&P and Russell indices changes over time; the fund will not automatically sell or cease to purchase stock of a company it holds just because the company’s market capitalization grows or falls outside these ranges.
