The market index has a standard deviation of 22% and the risk-free rate is 8%.
a. What is the standard deviation of stocks A and B?
b. Suppose that we were to construct a portfolio with proportions:
|
Stock A: |
0.3 |
|
Stock B: |
0.45 |
|
T-bills: |
0.25 |
Compute the expected return, standard deviation, beta, and nonsystematic standard deviation of the portfolio.
