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	(26%)
Below average	0.1	(12)
Average	0.3	11
Above average	0.3	30
Strong	0.2	51
	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.
