Consider the following information on Stocks I and II: |
State of Economy | Probability of State of Economy |
Rate of Return if State Occurs |
|
Stock I | Stock II | ||
Recession | .27 | .030 | −.22 |
Normal | .62 | .330 | .14 |
Irrational exuberance | .11 | .190 | .42 |
The market risk premium is 11.2 percent, and the risk-free rate is 4.2 percent. | |
a. | Calculate the beta and standard deviation of Stock I. (Do not round intermediate calculations. Enter the standard deviation as a percent and round both answers to 2 decimal places, e.g., 32.16.) |
b. | Calculate the beta and standard deviation of Stock II. (Do not round intermediate calculations. Enter the standard deviation as a percent and round both answers to 2 decimal places, e.g., 32.16.) |
c. | Which stock has the most systematic risk? |
d. | Which one has the most unsystematic risk? |
e. | Which stock is “riskier”? |
a)
Standard deviation of stock 1 = 15.01%
Expected return on stock 1 = 23.36%
Risk free rate = 4.2%
Market risk premium = 11.2%
23.36% = 4.2% + Beta * 11.2%
Beta = 1.71
b)
Standard deviation of stock 2 = 32.08%
Expected return = 7.36%
7.36% = 4.2% + beta* 11.2%
Beta = 0.28
c)
Beta is the measure of systematic risk, as Stock 1 has higher beta, Stock 1 has higher systematic risk.
d)
Standard deviation is the measure of unsystematic risk. Stock 2 has the highest unsystematic risk.
e)
Unsystematic risk can be mitigated through diversification however the systematic risk cannot be. Thus stock 1 is the riskier of the two.
