Problem 6-05 Expected Return: Discrete Distribution A stock's return has the following distribution: Demand for the Company's Products Probability of This Demand Occurring Rate of Return if This Demand Occurs (%) Weak 0.1 -30% Below average 0.2 -8 Average 0.4 15 Above average 0.2 35 Strong 0.1 75 1.0 Calculate the stock's expected return. Round your answer to two decimal places. % Calculate the standard deviation. Round your answer to two decimal places. %

Answer #1

E(r) = [Pi x Ri]

= [0.1 x -30%] + [0.2 x -8%] + [0.4 x 15%] + [0.2 x 35%] + [0.1 x 75%]

= -3% - 1.6% + 6% + 7% + 7.5% = 15.9%

(r) = [{Pi
x (E(r) - Ri)^{2}}]^{1/2}

= [{0.1 x (15.9% + 30%)^{2}} + {0.2 x (15.9% +
8%)^{2}} + {0.4 x (15.9% - 15%)^{2}} + {0.2 x
(15.9% - 35%)^{2}} + {0.1 x (15.9% -
75%)^{2}}]^{1/2}

= [210.68%^{2} + 114.24%^{2} + 0.32%^{2}
+ 72.96%^{2} + 349.28%^{2}]^{1/2} =
[747.49%^{2}]^{1/2} = 27.34%
