EXPECTED RETURNS

Stocks A and B have the following probability distributions of expected future returns:

Probability	A	B
0.1	(5%)	(32%)
0.3	6	0
0.3	16	19
0.2	20	30
0.1	33	37

1. Calculate the expected rate of return, r_B, for Stock B (r_A = 13.40%.) Do not round intermediate calculations. Round your answer to two decimal places. %

2. Calculate the standard deviation of expected returns, _A, for Stock A (_B = 19.46%.) Do not round intermediate calculations. Round your answer to two decimal places. %

3. Now calculate the coefficient of variation for Stock B. Round your answer to two decimal places.

4. Is it possible that most investors might regard Stock B as being less risky than Stock A?

   1. 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.
   2. 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.
   3. 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.
   4. 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.
   5. 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.
