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	(32%)
Below average	0.2	(11)
Average	0.3	13
Above average	0.3	31
Strong	0.1	51
	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.
