The general message of the Fama‐French tests (confirmed in detail by Chen (1991)) is that D/P and the default spread are high (expected returns on stocks and bonds are high) when times have been poor (growth rates of output have been persistently low). Stocks that moved more than the market had a … The analysis is based on asset returns and factor returns published on …
(Of course, all equilibrium model must be arbitrage-free, but not vice-versa.)
This has got me very confused. Ivo Welch, The Fama and French Three-Factor Model and Leverage: Compatibility with the Modigliani and Miller Propositions, By
one regression per period) and then aggregating the regression coefficients.

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. These factors are determined by use of a regression analysis. As empha- Many of the documented patterns are highly significant and seem almost certainly to be real, i.e., they are unlikely to be due to random chance or data-snooping biases. This is an extension to the regular three-factor model, created by Mark Carhart. There is a lot of debate about whether the outperformance tendency is due to market efficiency or market inefficiency. For example, load the grunfeld dataset from web. This correspondence also helps to clarify the interpretation of the estimates from the two methods: The Fama-Macbeth test is better suited for APT tests, while the plain Fama-French test is better suited for equilibrium tests. Fama-French 25 Portfolio Return Averages. The Fama Macbeth regression is to first run regression for each period cross-sectinally, i.e. Investors attention. This correspondence also helps to clarify the interpretation of the estimates from the two methods: The Fama-Macbeth test is better suited for APT tests, while the plain Fama-French test is better suited for equilibrium tests. (2004) and Carhart (1997) use the Fama MacBeth procedure to test such relationship. Re-… Today, we move beyond CAPM’s simple linear regression and explore the Fama French (FF) multi-factor model of equity risk/return. But this fama french 5-factor model still raises many questions. Some of you are confusing Fama-Macbeth which is a regression technique with regression on Fama-French factors. Small Minus Big (SMB) is one of three factors in the Fama/French stock pricing model, used to explain portfolio returns. However since my dataset suffers from both time series and cross sectional correlation. Ekaterini Panopoulou
Read more. In other words, the three factors used are SMB (small minus big), HML (high minus low) and the portfolio's return less the risk free rate of return. Prof. Maxim Ulrich talks about the seminal work of Fama, MacBeth (1973). 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. Mihály Ormos, ...

Again, size-unrelated beta has little explanatory power, even if it is the only explanatory variable.

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. We will document each step for importing and cleaning this data, to an extent that might be overkill. Basically right now I have my returns and factors that I calculated for hundreds of stocks over the past several years. Note: This page contains links to the data sources and the Octave source code which I used to generate the plots in my Visualizing the Small Cap and Value Effects post.
We use the cross-section regression approach of Fama and MacBeth (FM 1973) to construct cross-section factors corresponding to the time-series factors of Fama a In a previous post, we reviewed how to import the Fama French 3-Factor data, wrangle that data, and then regress our portfolio returns on the factors.Please have a look at that previous post, as the following work builds upon it.
