Fama and french three factor model research paper
Capm vs three factor model
In a recent paper, Foye, Mramor and Pahor propose an alternative three factor model that replaces the market value of equity component with a term that acts as a proxy for accounting manipulation. Foye tested the five-factor model and in the UK and raises some serious concerns. Since these companies have experienced some sort of difficulty, it seems plausible that they would be exposed to greater risk of bankruptcy or other financial troubles than their more highly valued counterparts. The first being the ability to categorize investments depending on how their returns vary with different risk factors. BA measures of the exposure an asset has to market risk although this beta will have a different value from the beta in a CAPM model as a result of the added factors , SA measures the level of exposure to size risk and HA measures the level of exposure to value risk. Firstly, he questions the way in which Fama and French measure profitability. Hire Writer SMB, which stands for Small Minus Big, is designed to measure the additional return investors have historically received by investing in stocks of companies with relatively small market capitalization. Whilst a momentum factor wasn't included in the model since few portfolios had statistically significant loading on it, Cliff Asness , former PhD student of Eugene Fama and co-founder of AQR Capital has made the case for its inclusion. By comparing the realized returns with that predicted by the CAPM model, we find that the model is often incorrect.
Firstly, he questions the way in which Fama and French measure profitability. The historical returns of a particular portfolio are regressed against the historical values of the three factors, generating estimates of the coefficients. The difference arises from whether or not one believes in the efficient market theory.
If the model fully explains stock returns, the estimated alpha should be statistically indistinguishable from zero. The first being the ability to categorize investments depending on how their returns vary with different risk factors.
These factors are calculated with combinations of portfolios composed by ranked stocks BtM ranking, Cap ranking and available historical market data. Hire Writer SMB, which stands for Small Minus Big, is designed to measure the additional return investors have historically received by investing in stocks of companies with relatively small market capitalization.
