T. Rowe Price New Horizons Fund (PRNHX) is an open-end mutual fund that seeks long-term capital growth by investing primarily in common stocks of small, emerging growth companies, preferably early in their corporate life cycle; it may also invest in companies offering accelerating earnings growth due to rejuvenated management, new products, or structural changes, with a portfolio emphasizing small- and mid-cap growth stocks across sectors such as technology (approximately 28%), healthcare (21%), and industrials (18%). The fund offers diversified exposure through holdings including Dayforce Inc., Lattice Semiconductor Corp., Teledyne Technologies Inc., and argenx SE ADR, alongside aggregate miscellaneous equity positions; it maintains a net expense ratio of 0.79%, total net assets exceeding $14 billion, and is available to U.S. investors with a minimum initial investment of $2,500. Launched on June 3, 1960, and domiciled in the United States, the fund operates with a focus on U.S. stocks (88%) supplemented by non-U.S. equities (6%) and limited cash holdings.
In recent major changes, Shaun Currie joined as co-portfolio manager with Joshua K. Spencer on July 21, 2025, assuming sole portfolio manager and Investment Advisory Committee chair responsibilities effective October 1, 2025, following Spencer's departure on September 30, 2025. Portfolio adjustments during late 2024 and 2025 included significant sales such as trimming Paylocity to manage position size, alongside additions like Fabrinet for its advanced optical packaging capabilities amid accelerating chip development; these shifts supported ongoing bets in high-conviction sectors like data centers and cryptocurrency exposure. While T. Rowe Price Group, the fund's sponsor, pursued broader strategic partnerships such as with Goldman Sachs in 2025 for retirement and wealth investment solutions, no fund-specific acquisitions, funding rounds, or name changes were reported within the last two years.
