Small Minus Big (SMB) is one of three factors in the Fama/French stock pricing model, used to explain portfolio returns. These factors are determined by use of a regression analysis. In this data set, we have 10 companies, each one having 20 years of data. Some of you are confusing Fama-Macbeth which is a regression technique with regression on Fama-French factors. Importing and Wrangling the Fama French Factors. 5 comments. Fama-Macbeth method has nothing to do with any factor or risk or return. These include "momentum," "quality," and "low volatility," among others. The Fama MacBeth methodology is one way to deal with panel data.

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.
Perform Fama-French three-factor model regression analysis for one or more ETFs or mutual funds, or alternatively use the capital asset pricing model (CAPM) or Carhart four-factor model regression analysis. In support of market inefficiency, the outperformance is explained by market participants incorrectly pricing the value of these companies, which provides the excess return in the long run as the value adjusts.

This is relevant because the Fama-French portfolios (typically people use the 5x5 size and book-to-market portfolios) are your test assets which you use to estimate the factor model betas. Gerard Hoberg
Many papers in the empirical finance literature implement tests of asset pricing models either via Fama-French time-series regressions or via Fama-Macbeth cross-sectional regressions. I understand fama french, I'm a little confused on what fama macbeth is and how it is different and how it is applied here.

The Fama-French five-factor model which added two factors, profitability and investment, came about after evidence showed that the three-factor model was an inadequate model for expected returns because it’s three factors overlook a lot of the variation in average returns related to profitability and investment (Fama and French, 2015).

Researchers have expanded the Three-Factor model in recent years to include other factors. …
Portfolio standard deviation. Different methods and models of pricing securities and thereby determining expected returns on capital investments has been improved and developed over the years. Given the ability to explain 95% of a portfolio’s return versus the market as a whole, investors can construct a portfolio in which they receive an average expected return according to the relative risks they assume in their portfolios. Basically right now I have my returns and factors that I calculated for hundreds of stocks over the past several years. Thus, iM is the covariance risk of asset i in M measured relative to the average covariance risk of assets, which is just the variance of the market return. hide. Implied cost of equity (ICC) Herding behavior. So in total there are N x T obs. For the method described here, the only data requirements are the return on a market index and the return on the stock, over the estimation period, if CAPM is used. In support of market efficiency, the outperformance is generally explained by the excess risk that value and small-cap stocks face as a result of their higher cost of capital and greater business risk. show that the Fama French portfolios have a strong factor structure which biases the researcher in favor of factor models. The FM regressions in Table III confirm the importance of book‐to‐market equity in explaining the cross‐section of average stock returns. Here are a few: 1. Today, we move beyond CAPM’s simple linear regression and explore the Fama French (FF) multi-factor model of equity risk/return.
However, this is a common mistake, and here’s why. After discussing the value and momentum effect mostly in terms of investment strategies, in the following the Fama-French three-factor model  and Carhart’s survey of mutual fund returns including momentum  will be discussed. … Fama-MacBeth: a Replication The basic theoretical claim described in FM and resulting from the Sharpe-Lintner version of the CAPM simply states that variability in market betas accounts for a significant portion of the cross-sectional variability of stock returns at a certain point in .
