DFA U.S. Micro Cap Portfolio (DFSCX) is an institutional class mutual fund managed by Dimensional Fund Advisors L.P. (DFA), a global investment firm that seeks long-term capital appreciation by investing in a broad and diverse group of U.S. micro cap company securities using a market capitalization weighted approach. The portfolio provides exposure to the smallest stocks listed in the U.S. market, including equity securities, futures contracts, and options on futures for U.S. equity indices to manage cash flows and market exposure; it emphasizes well-diversified holdings across micro cap segments, with top positions in companies such as CorVel Corp., Cavco Industries Inc., and Adtalem Global Education Inc. DFA, founded in 1981 and headquartered in Austin, Texas, operates this fund as part of its systematic equity strategies offered through mutual funds, exchange-traded funds, separately managed accounts, and model portfolios targeting institutional and advisor-served investors primarily in the U.S. market.
In recent developments, Dimensional's Investment Committee approved strategy enhancements in August 2025 for select funds, including refinements to emphasize higher profitability and lower relative price securities within small and mid cap value segments, though the U.S. Micro Cap Portfolio maintains its core micro cap focus with ongoing exclusions of lowest profitability securities across eligible size ranges. The firm renewed its transfer agent relationship with SS&C Technologies Holdings Inc. in March 2025 to support mutual funds in the U.S. and U.K., enhancing operational services for funds like DFSCX. Additionally, Dimensional expanded its ETF offerings with UCITS ETF launches on the London Stock Exchange in December 2025, supported by State Street, building on prior U.S. and Australian active ETF introductions while continuing to grow its $821 billion in discretionary assets under management. DFA maintains global operations through 15 offices across the U.S., Canada, U.K., Germany, Netherlands, Australia, Singapore, and Japan.
