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	(50%)
Below average	0.2	(10)
Average	0.3	12
Above average	0.3	20
Strong	0.1	56
	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: _______
