Vanguard PRIMECAP Fund Admiral Shares (VPMAX) is an open-end mutual fund that seeks long-term capital appreciation by investing primarily in mid- and large-capitalization stocks with above-average earnings growth potential not reflected in their current market prices; the portfolio emphasizes growth-oriented equities in sectors such as information technology (approximately 28%), health care (24%), consumer discretionary (15%), industrials (13%), and financials (9%), with top holdings including Eli Lilly & Co., Alphabet Inc., Micron Technology Inc., Microsoft Corp., and NVIDIA Corp. The Admiral Shares class, with a net expense ratio of 0.29%, a minimum initial investment of $50,000, and total net assets exceeding $71 billion as of recent data, features low turnover of 3.8% and benchmarks performance against the S&P 500 Index. Launched on November 12, 2001, and domiciled in the United States with operations focused on U.S. investors, the fund is subadvised by PRIMECAP Management Company, which has maintained a longstanding partnership with The Vanguard Group, Inc. since the late 1980s. In a notable recent development, Vanguard reopened the PRIMECAP Fund, including VPMAX Admiral Shares, to all investors without restriction in May 2023 after it had been closed to new accounts since 2004, enabling broader access to PRIMECAP's research-driven investment approach. PRIMECAP Management continues to oversee the fund with a team of five portfolio managers, upholding a long-term orientation with average holding periods of around 20 years for flagship positions.
