4.3 Results of the regressions for the CAPM
Since part of our research is to test whether or not the FF3FM outperforms the CAPM on the
Swedish market, we conducted a regression analysis for each of the sixteen dependent
portfolios in compliance with the model: Rit - Rft = a + bi[Rmt-Rft]
The intercept and its related p-values, the coefficient for the explanatory variable as well as
the value of the adjusted r-squared are presented for the period of 2005 – 2009 in table 9.
For the CAPM portfolios there are three portfolios where α is positively significant at the 5 %
level, S_2, 2_L and 3_L. The adjusted R² lies between 18 % and 83 %, which is well below
the FF3FM values (41 % - 88 %). Just as we did for the FF3FM regression, we excluded the
2007 portfolios and redid the regression; the results are presented in table 9.
