EXPECTED RETURNS

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

Probability	A	B
0.1	(10%)	(35%)
0.2	3	0
0.3	11	19
0.3	19	27
0.1	32	47

1. Calculate the expected rate of return, r_B, for StockB (r_A = 11.80%.) 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 = 21.10%.) Do not roundintermediate calculations. Round your answer to two decimalplaces.
   %

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

4. Is it possible that most investors might regard Stock B as beingless 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 lessrisky 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 asrisky 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 lessrisky 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 morerisky 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 lessrisky in a portfolio sense.
