Just as for the 2008 portfolios neither one of the α:s are positively significant at the 5 % level
for the 2009 portfolios. The adjusted R² value lies between 29 % and 92 %. Here we actually
get an anomaly in the form of a single negative R² value -7% for one of the portfolios.
Since the value of the adjusted R² were as low as 41 % for the period 2005 – 2009, we redid
the regression but this time we excluded the 2007 portfolios.
