What is the Fama and French Three Factor Model? 

The Fama and French Three Factor Model is explains stock returns. Eugene Fama and Kenneth French cultivated this model to analyze beyond the traditional way of CAPM (Capital Asset Pricing Model). The three factors in the Fama and French three-factor model are the following, 

  • – Size (SMB – Small Minus Big): In this model, small-cap stocks generally have a higher return than large-cap stocks.
  • – Value (HML – High Minus Low): In this model, the emphasis is placed on value stocks over growth stocks, with the specification of excess return on a high book-to-market ratio. 
  • – Market Risk (Portfolio’s return less than the risk-free rate of return): In this model, market risk is calculated by the excess return of the overall market over the risk-free rate.

One of the three factors in the model is size, but specifically, an emphasis on the small minus big anomaly. Both Eugene and Kenneth discovered that small-cap stocks generally outperform large-cap companies. 

Two main reasons for the success of small-cap stocks are the excess risk that small-cap stocks take on because of a higher cost of capital or when investors incorrectly price the value of the stocks, which results in higher performance.
