Question: Consider the two (excess return) index model regression results for A and B: Stock A R A = -1 % + 1.1 R M R

Consider the two (excess return) index model regression results for A and B:

Stock A

RA = -1 % + 1.1 RM

R -square = 0.640

Residual standard deviation = 8.9%

Stock A

RB = 3 % + 1.4 R M

R square= 0.764

Residual standard deviation= 7.3%

1. Which stock has more firm-specific risk and why?

2. Which has greater market risk and why?

3. For which stock does market movement explain a greater fraction of return variability and why?

4. If rf were constant at 4% and the regression had been run using total rather than excess returns, what would have been the regression intercept for stock A?
