a. What are the risk factors incorporated in the Fama and French three factor models? How are they measured? b. Why do we not subtract the risk-free rate from SMB or HML? Why do we subtract the riskfree rate from Rm ? c. Cahart (1997) incorporated a forth factor so called momentum into the Fama-French model. Define momentum and describe how it is measured. d. Recently, Fama and French (2015) introduce the five-factor model. What is the difference in the way the SMB and HML factors are measured in the three-factor model and the five-factor model? e. Suppose I sort stocks into portfolios by their betas to detect any new return pattern and document the results in the below table. Is there any evidence suggesting a new anomaly (i.e. return pattern not explained by existing asset pricing models) with respect to the CAPM?
