T. Rowe Price Mid-Cap Growth Fund, Inc.
Actively managed U.S. stock fund
The fund seeks to provide long-term capital appreciation by investing in mid-cap stocks with potential for above-average earnings growth.
The fund invests in a diversified portfolio of mid-cap common stocks selected for above-average earnings growth potential, favoring companies with proven products, strong earnings records, demonstrated growth sustainability, exposure to growing industries, or valuations that appear to undervalue their prospects. The fund may also hold privately held companies and recent IPOs to a limited extent. Because performance depends on the adviser's stock selections, the fund's results will diverge from any benchmark.

How it has done
RPMGX share class · total returns with dividends reinvested
Volatility over the last 12 months: 11.11%. Past returns are a record, not a forecast.
May 2026 and Jun 2026 have been filed since the trailing figures were struck, so they are not in the table above or the curve — every figure here shares one cut-off, which is what makes them comparable with other funds.
The 5 share classes hold the same portfolio
| Share class | Expense ratio | 1 year | 3 years | 5 years | Worst fall |
|---|---|---|---|---|---|
| 0.75% | +13.47% | +29.86% | +14.10% | -13.16% | |
| 1.01% | +13.22% | +28.88% | +12.67% | -13.21% | |
| 1.29% | +12.88% | +27.75% | +11.07% | -13.28% | |
| 0.63% | +13.63% | +30.38% | +14.84% | -13.12% | |
| 0.00% | +14.34% | +32.86% | +18.50% | -12.98% |
These classes hold the same portfolio, so the 7.44pp spread over 5 years is the cost difference between them — roughly 1.49pp a year — not a difference in what they own.
