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
  1. Calculate the expected rate of return, , for Stock B ( = 13.90%.) Do not round intermediate calculations. Round your answer to two decimal places.

      %

  2. Calculate the standard deviation of expected returns, σA, for Stock A (σB = 17.22%.) Do not round intermediate calculations. Round your answer to two decimal places.

      %

    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?

    1. If Stock B is more 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.
    2. If Stock B is more highly correlated with the market than A, then it might have the same beta as Stock A, and hence be just as risky in a portfolio sense.
    3. 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.
    4. 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.
    5. If Stock B is more highly correlated with the market than A, then it might have a higher beta than Stock A, and hence be less risky in a portfolio sense.

    -Select which one is correct.

  3. 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?

    1. In a stand-alone risk sense A is less risky than B. If Stock B is more highly correlated with the market than A, then it might have the same beta as Stock A, and hence be just as risky in a portfolio sense.
    2. 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 lower beta than Stock A, and hence be less risky in a portfolio sense.
    3. 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.
    4. In a stand-alone risk sense A is more risky than B. 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.
    5. In a stand-alone risk sense A is more 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.

    -Select which one is correct.

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.
