In a recent episode of Behind the Ticker, Rob Harvey, Vice President at Dimensional Fund Advisors (DFA), shared his personal journey into asset management and gave an in-depth look at DFA’s unique approach to building portfolios, particularly their work in the ETF space. Harvey described how he first encountered Dimensional while managing external asset managers at Cisco Systems, where their emphasis on evidence-based investing and disdain for market predictions immediately stood out. After attending a Dimensional conference and hearing academic legends like Eugene Fama and Ken French present, Harvey was convinced and eventually joined DFA, relocating to Austin, Texas.

Harvey explained that DFA’s core mission is to help investors achieve their financial goals by providing investment solutions based on robust academic research, rather than focusing on marketing or chasing hot trends. He emphasized Dimensional’s long-standing partnership model with financial advisors, which prioritizes education, client communication, and long-term outcomes over product sales. This commitment to advisors and evidence-based investing remains central even as DFA expands its reach through ETFs, making their historically advisor-only strategies accessible to a broader audience without compromising their foundational principles.

The conversation focused heavily on DFA’s investment philosophy, particularly their emphasis on factors like size, value, and profitability, which are systematically applied across all portfolios. Harvey noted that DFA is highly disciplined in vetting new research before incorporating it into their strategies, ensuring that any new factors—such as profitability, which was added in 2012—meet a high bar for robustness and persistence across time and markets. DFA’s portfolios are managed actively on a daily basis, providing flexibility to capture real-world developments in ways traditional index funds cannot, while maintaining low fees and broad diversification.

Harvey also provided an overview of DFAI

, Dimensional’s International Core Equity ETF. He described DFAI as a market-wide, low-tracking-error strategy that lightly tilts toward premiums like small size, value, and profitability, offering enhanced expected returns over a standard index fund. DFAI differs from traditional international index funds by including a broader set of securities, especially micro-caps, and by incorporating real-time momentum screens to avoid value traps and boost performance. Harvey positioned DFAI as an ideal core international equity holding for advisors seeking to move beyond passive indexing without sacrificing diversification or cost efficiency.
