T. Rowe Price New Horizons Fund, Inc.
Actively managed U.S. stock fund
The fund seeks long-term capital growth by investing primarily in common stocks of small, rapidly growing companies.
The fund invests in common stocks of small, emerging growth companies selected for characteristics including effective management, innovation, pricing flexibility, and sound financial practices, often early in their corporate life cycle before broad market recognition. The portfolio may include privately held companies and recent IPOs, and may concentrate significantly in single economic sectors such as information technology, industrials, or health care. Foreign stocks may be held alongside U.S. equities in pursuit of the fund's objectives.

How it has done
PRNHX share class · total returns with dividends reinvested
Volatility over the last 12 months: 14.13%. 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 3 share classes hold the same portfolio
| Share class | Expense ratio | 1 year | 3 years | 5 years | Worst fall |
|---|---|---|---|---|---|
| 0.79% | +26.06% | +34.11% | -7.04% | -18.88% | |
| 0.66% | +26.22% | +34.64% | -6.47% | -18.84% | |
| 0.00% | +27.06% | +37.33% | -3.39% | -18.66% |
These classes hold the same portfolio, so the 3.65pp spread over 5 years is the cost difference between them — roughly 0.73pp a year — not a difference in what they own.
