Stocks A and B have the following probability distributions of expected future returns:
Probability | A | B | ||
0.1 | (15 | %) | (37 | %) |
0.1 | 4 | 0 | ||
0.5 | 14 | 23 | ||
0.2 | 19 | 27 | ||
0.1 | 39 | 37 |

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?
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?
a. Expected return of B =0.1*-37%+0.1*0%+0.5*23%+0.2*27%+0.1*37%
=16.90%
b. Standard Deviation of A
=(0.1*(-15%-13.60%)^2+0.1*(4%-13.60%)^2+0.5*(14%-13.60%)^2+0.2*(19%-13.60%)^2+0.1*(39%-13.60%)^2)^0.5=12.71%
Coefficient of Variation =Standard Deviation/Expected Return of B
=19.96%/16.90% =1.18
Option
III is correct option because lower the beta lower
is the risk.
c. Sharpe Ratio of A =(Return of A-Risk free rate)/Standard
Deviation=(13.60%-1.5%)/12.71% =0.9523
Sharpe Ratio of B =(Return of A-Risk free rate)/Standard
Deviation=(16.90%-1.5%)/19.96% =0.7715
Option
IV is correct option
