A stock's returns have the following distribution:

Demand for the Company's Products	Probability of This Demand Occurring	Rate of Return If This Demand Occurs
Weak	0.2	(30%)
Below average	0.3	(11)
Average	0.3	11
Above average	0.1	28
Strong	0.1	66
	1.0

Assume the risk-free rate is 2%. Calculate the stock's expected return, standard deviation, coefficient of variation, and Sharpe ratio. Do not round intermediate calculations. Round your answers to two decimal places.

Stock's expected return:

Standard deviation:

Coefficient of variation:

Sharpe ratio:

B.

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

Probability	A	B
0.2	(8%)	(23%)
0.2	5	0
0.2	13	22
0.1	23	30
0.3	39	41

Calculate the expected rate of return, , for Stock B ( = 16.00%.) Do not round intermediate calculations. Round your answer to two decimal places. %

Calculate the standard deviation of expected returns, A, for Stock A (B = 23.85%.) 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.
