They wrote a series of papers that cast doubt on the validity of the Capital Asset Pricing Model (CAPM), which posits that a stock's beta alone should explain its average return.

[5] Also in 2007, Professor French was elected to the American Academy of Arts and Sciences (AAAS).
French is a board member of Dimensional Fund Advisors[6] in Austin, Texas, where he also works as consultant and head of investment policy.
