B. Fama‐MacBeth Regressions. The relation between average returns and beta is more or less flat. Investopedia uses cookies to provide you with a great user experience.
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.

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.
