Stocks A and B have the following probability distributions of expected future returns:
Probability | A | B | ||
0.1 | (13 | %) | (21 | %) |
0.2 | 6 | 0 | ||
0.5 | 16 | 20 | ||
0.1 | 20 | 29 | ||
0.1 | 40 | 45 |

Now calculate the coefficient of variation for Stock B. Do not round intermediate calculations. Round your answer to two decimal places.
Is it possible that most investors might regard Stock B as being less risky than Stock A?
-Select which one is correct.
Assume the risk-free rate is 1.5%. What are the Sharpe ratios for Stocks A and B? Do not round intermediate calculations. Round your answers to four decimal places.
Stock A:
Stock B:
Are these calculations consistent with the information obtained from the coefficient of variation calculations in Part b?
-Select which one is correct.
Answer:
Part a. and Part b. | |||||||
Probability | A | B | PirAi | PirBi | Std.DivA | Std.Div.B | |
0.1 | -13% | -21% | -1.30% | -2.10% | 0.72% | 1.32% | |
0.2 | 6% | 0 | 1.20% | 0.00% | 0.12% | 0.47% | |
0.5 | 16% | 20% | 8.00% | 10.00% | 0.02% | 0.11% | |
0.1 | 20% | 29% | 2.00% | 2.90% | 0.04% | 0.19% | |
0.1 | 40% | 45% | 4.00% | 4.50% | 0.68% | 0.88% | |
13.90% | 15.30% | 12.61% | 17.22% | ||||
Coefficient of variation for stock B = | 1.13 | ||||||
0.91 | |||||||
In multiple choice questions, the correct answer is IV | |||||||
If Stock B is less highly correlated with the market than A, then it might have a higher beta than Stock A, and hence be more risky in a portfolio sense. | |||||||
Part c. | |||||||
Sharpe Ratio = (Expected return - Risk free rate) / Standard deviation | |||||||
Stock A | 0.9837 | ||||||
Stock B | 0.8013 | ||||||
In multiple choice questions, the correct answer is III | |||||||
In a stand-alone risk sense A is less risky than B. If Stock B is less highly correlated with the market than A, then it might have a higher beta than Stock A, and hence be more risky in a portfolio sense. |
