Problem 8-6
Expected returns
Stocks A and B have the following probability distributions of expected future returns:
Probability | A | B |
0.1 | -7% | -38% |
0.2 | 6 | 0 |
0.4 | 14 | 18 |
0.2 | 24 | 25 |
0.1 | 28 | 47 |
Calculate the expected rate of return, rB, for Stock
B (rA = 13.70%.) Do not round intermediate calculations.
Round your answer to two decimal places.
%
Calculate the standard deviation of expected returns,
σA, for Stock A (σB = 21.17%.) Do not round
intermediate calculations. Round your answer to two decimal
places.
%
Now calculate the coefficient of variation for Stock B. Round your answer to two decimal places.
Is it possible that most investors might regard Stock B as being less risky than Stock A?
Expected returns=Sum(probability*returns)
Standard deviation=Sqrt(Sum(probability*(returns-expected returns)^2))
Coefficient of variation=Standard deviation/expected returns
1.
=0.1*(-38%)+0.2*0%+0.4*18%+0.2*25%+0.1*47%
=13.100%
2.
=sqrt(0.1*(-7%-13.70%)^2+0.2*(6%-13.70%)^2+0.4*(14%-13.70%)^2+0.2*(24%-13.70%)^2+0.1*(28%-13.70%)^2)
=9.82%
3.
=21.17%/13.100%
=1.616030534
4.
If Stock B is less highly correlated with the market than A, then
it might have a lower beta than Stock A, and hence be less risky in
a portfolio sense.
