Vanguard U.S. Growth Fund (VWUSX) is an actively managed open-end mutual fund that seeks long-term capital appreciation by investing primarily in large-capitalization stocks of U.S. companies with above-average earnings growth potential and reasonable stock prices relative to expected earnings; the fund maintains a diversified portfolio across sectors such as technology (approximately 49%), retail trade (17%), finance (11%), and non-durables (9%), with top holdings typically including well-established blue-chip growth names; it offers Investor Shares with a net expense ratio of 0.32%, a minimum initial investment of $3,000, and additional investments from $1, as of mid-2025 managing approximately $10.9 billion in share class assets within a total net assets base exceeding $51 billion. Launched on January 6, 1959, the fund operates from Vanguard's headquarters in Malvern, Pennsylvania, and serves retail and institutional investors across the United States through multiple subadvisors including Wellington Management Company LLP, Jackson Square Partners LLC, Jennison Associates LLC, and Baillie Gifford Overseas Ltd.. In recent years, the fund has undergone advisory realignments, including the 2019 addition of Wellington Management with an increased allocation and the removal of Vanguard Quantitative Equity Group in May 2023; a significant 2018-2019 merger integrated the Vanguard Morgan Growth Fund into VWUSX, enhancing its multi-manager structure and lowering expense ratios to current levels; no major funding rounds, acquisitions, or product launches specific to VWUSX have been announced since 2023, though Vanguard as a firm continues portfolio manager transitions and expense optimizations across its offerings.
