Does the Fama-French three-factor model and Carhart four-factor model explain portfolio returns better than CAPM? : - A study performed on the Swedish stock market.
Abstract:
This essay will compare the capital asset pricing model (CAPM), Fama and French threefactor
model and Carhart´s four-factor model, to see which of these models that can explain
portfolio excess returns best on the Swedish stock market. This thesis will tempt to validate
the three and four-factor models because of the limited amount of research done on the
Swedish stock market. The results indicate that the three-factor model improves explanatory
power for portfolio returns in comparison to the CAPM, and the four-factor model gives a
small improvement in the explanatory power compared to the three-factor model. The results
also indicate that all models have a low explanatory power when the market is volatile.
