Question

Consider the following information: Portfolio Expected Return Beta Risk-free 8 % 0 Market 10.2 1.0 A 8.2 0.7 a. Calculate the expected return of portfolio A with a beta of 0.7. (Round your answer to 2 decimal places.) Expected return % b. What is the alpha of portfolio A. (Negative value should be indicated by a minus sign. Round your answer to 2 decimal places.) Alpha % c. If the simple CAPM is valid, is the above situation possible? Yes No

Answer 1

Following Information provided -

Portfolio	Portfolio Return	Beta
Risk Free	8%	0
Market	10.20%	1
A	8.20%	0.7
