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	(26%)
Below average	0.1	(11)
Average	0.4	12
Above average	0.2	22
Strong	0.1	56
	1.0

Assume the risk-free rate is 3%. 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: ?
