Dimensional Fund Advisors (DFA) is a global investment firm founded in 1981. It applies academic research to create investment strategies, focusing on passive investing with a twist, targeting higher expected returns through asset allocation rather than market timing or stock picking[1][3]. DFA offers mutual funds, ETFs, separately managed accounts, and model portfolios[2]. Their target audience includes institutional investors and individual clients through selected advisory firms[3]. The unique selling proposition is their scientific approach to investing, leveraging research from Nobel laureates like Eugene Fama and Kenneth French to minimize trading costs and maximize returns[2][3].
