Fama Macbeth regression refers to a procedure to run regression for panel data (where there are N different individuals and each individual corresponds to multiple periods T, e.g. They compare the movement of the prices from time to time. In two previous posts, we calculated and then visualized the CAPM beta of a portfolio by fitting a simple linear model. # In my portfolio, I show how the popular Fama-MacBeth (1973) procedure is constructed in R. # The procedure is used to estimate risk premia and determine the validity of asset pricing models. First, for some background information read Kevin Goulding’s blog post, Mitchell Petersen’s programming advice, Mahmood Arai’s paper/note and code (there is an earlier version of the code with some more comments in it).

Using thousands of random stock portfolios, Fama and French conducted studies to test their model and found that when size and value factors are combined with the beta factor, they could then explain as much as 95% of the return in a diversified stock portfolio. The relation between average returns and beta is more or less flat. Now, there are also the four-factor and the five-factor versions of the model, which require more information to calculate but give more detailed results. It has become common practice in the asset pricing literature to look at both 1-factor and 3-factor alphas.

I find Fama-MacBeth appealing for accounting for time-effects (it's easy to calculate time-varying betas, for example) it has easy intuition for the financial literature, and ; it can be applied to unbalanced panels. one regression per period) and then aggregating the regression coefficients. Small Minus Big (SMB) is one of three factors in the Fama/French stock pricing model, used to explain portfolio returns. Robert B. A multi-factor model uses many factors in its computations to explain market phenomena and/or equilibrium asset prices. By including these two additional factors, the model adjusts for this outperforming tendency, which is thought to make it a better tool for evaluating manager performance.
