# Question: Consider the two excess return index model regression results for

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

RA = .01 + 1.2RM

R- squared = .576

σ ( e) = 10.3%

RB = - .02 + .8RM

R- squared = .436

σ(e) = 9.1%

a. Which stock has more firm- specific risk?

b. Which has greater market risk?

c. For which stock does market movement explain a greater fraction of return variability?

d. Which stock had an average return in excess of that predicted by the CAPM?

e. If rf were constant at 6 percent and the regression had been run using total rather than excess returns, what would have been the regression intercept for stock A?

Are the intercepts of the two regressions consistent with the CAPM? Interpret their values. Suppose that the index model for stocks A and B is estimated with the following results: RA = .03 + .70RM + eA RB = 2.02 + 1.20RM + ...Use the data from The Financial Post in Figure 10.8 to construct the trin ratio for the TSX. Is the trin ratio bullish or bearish? Return to Table 12.1 and calculate the real and nominal rates of return on the RRB bond in the second and third years.
