This Paper Could Change How You Invest
Ben Felix breaks down Fama and French's 1993 three-factor model paper, which showed that size and value factors alongside market beta explain ~90% of return differences across diversified portfolios — up from ~60% with CAPM alone.
- The Fama-French three-factor model (market + size + value) jumped explanatory power from ~60% to ~93% across 25 test portfolios, leaving near-zero unexplained alpha in most cases.
- Active managers who beat the market usually did so via factor exposure (small caps, value stocks) — replicable cheaply without paying active fees.
- The later five-factor model added profitability (RMW) and investment (CMA), pushing explanatory power toward 95% and becoming the workhorse model in academic finance.
- Dimensional Fund Advisors and Avantis Investors are the main fund companies translating this factor research into purchasable low-cost portfolios.
- > "The cross-section of average returns on US common stocks shows little relation to the market betas of the Sharpe-Lintner asset pricing model." — Fama & French
