Dimensional Fund Advisors (DFA) and Vanguard have intersecting histories rooted in the development of the first-ever index fund. Vanguard's market-cap weighted index funds have been nothing short of revolutionary and they became synonymous with sensible investing for many good reasons, but Dimensional took implementing the ideas from academic finance a few steps further, leading to their own deserved acclaim. In today's episode, Ben and Dan analyze over 30 years of history between DFA and Vanguard, from their founding and relationship to their rise as global leaders in asset management. We discover how their approaches to foundational finance theory differ, whether diversification is mostly semantics, and how DFA and Vanguard compare to one another over 25 years of matched US-domiciled mutual funds. We also discuss which approach is easier to implement, essential insights for fund advisors, DFA's downsides despite its long-term outperformance of the Vanguard 500, and an uplifting cancer update from Ben in today's After Show. For practical investment takeaways, tune in today!
