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	0.1	(24%)
Below average	0.1	(13)
Average	0.4	13
Above average	0.3	38
Strong	0.1	45
	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: ?%
