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 | (38%) |
Below average | 0.1 | (12) |
Average | 0.4 | 13 |
Above average | 0.3 | 20 |
Strong | 0.1 | 47 |
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:
Expected Return = Sum of (probability*Return)
Variance formula = Sum of (Probability * (Actual return - Required
return)^2)
Standard deviation formula = √ Variance
Coefficient of Variation = standard deviation/Expected
Return
Sharpe ratio = (Expected Return - risk free rate)/Standard
deviation
Probability Return of stock
Product =Prob.*Return Return deviation
Squared deviation Product = Sq dev * Prob.

Variance = 4.4849%
Standard deviation=
21.18%
Coefficient of Variation = 21.18%/10.90%=
1.9429
Sharpe ratio = (10.90% -3%)/21.18%
=0.3730
