T. Rowe Price Growth Stock Fund (PRGFX) is an open-end mutual fund managed by T. Rowe Price Group, Inc., that seeks long-term capital growth through investments primarily in common stocks of large-cap growth companies; it normally invests at least 80% of its net assets in such equities, with a focus on U.S. stocks supplemented by select foreign securities, and maintains a non-diversified portfolio emphasizing sectors like technology, communication services, and consumer cyclical. The fund offers investors exposure to high-conviction growth holdings including NVIDIA Corp., Microsoft Corp., Apple Inc., Alphabet Inc., and Broadcom Inc., which comprise a significant portion of its approximately $53 billion in total net assets as of late 2025; it features a net expense ratio of 0.65%, daily pricing, a minimum initial investment of $2,500, and targets individual investors, retirement plans, institutions, and financial intermediaries in the large growth category benchmarked against the S&P 500 and Russell Growth indices. Launched on April 11, 1950, the fund operates from T. Rowe Price's headquarters in Baltimore, Maryland, with the parent firm's global presence across 17 international offices serving clients in 55 countries. In recent developments, comanager Jim Stillwagon, who joined the firm in 2017, assumed the lead manager role effective January 1, 2025, ahead of the accelerated departure of prior lead manager Joe Fath on August 1, 2025, ensuring an orderly transition while maintaining the strategy's Above Average People rating; these changes reflect T. Rowe Price's ongoing commitment to experienced active management amid its focus on growth investing.
