Qusetion: Consider the two (excess return) index model regression results for A and B:
RA = -1.3% + 1.5RM
R-square = 0.670
Residual standard deviation = 13.6%
RB = 0.7% + 1.2RM
R-square = 0.572
Residual standard deviation = 12.2%
a. Which stock has more firm-specific risk?
b. Which stock has greater market risk?
c. For which stock does market movement has a greater fraction of return variability?
d. If rf were constant at 6.8% and the regression had been run using total rather than excess returns, what would have been the regression intercept for stock A? (Negative value should be indicated by a minus sign. Round your answer to 2 decimal place. Omit the "%" sign in your response.)
