Consider the two (excess return) index model regression results for A and B : R A = 1.1% + 0.95 R M R -square =

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

RA = 1.1% + 0.95RM

R-square = 0.488

Residual standard deviation = 9.2%

RB = 0.4% + 1.4RM

R-square = 0.576

Residual standard deviation = 12.5%

1) If rf were constant at 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.)

Intercept _____%

Question 2:

Suppose that the index model for stocks A and B is estimated from excess returns with the following results:

RA = 2.8% + 1.00RM + eA

RB = 1% + 1.3RM + eB

M = 18%; R-squareA = 0.27; R-squareB = 0.13

Assume you create portfolio P with investment proportions of 0.70 in A and 0.30 in B.

1. What is the standard deviation of the portfolio? (Do not round your intermediate calculations. Round your answer to 2 decimal places.)

3. What is the firm-specific variance of your portfolio? (Do not round your intermediate calculations. Round your answer to 4 decimal places.)
