Calculate the expected return and standard deviation of two securities.
Expected or Average return =sum of (Prob.*Return)
Variance formula = Sum of (Probability * (Actual return - Expected
return)^2)
Standard deviation formula = √ Variance
Market condition Prob. Return A
Prob*Return (Prob.*( return- Expected return)^2)
Trough 0.05 -20.00
-1.00 32.51
Recession 0.40 -5.00
-2.00 44.10
Expansion 0.50 15.00
7.50 45.13
Peak 0.05 20.00
1.00 10.51
Total
5.50 132.25
Expected Return= 5.50 %
Variance of stock Investment is 132.25
standard deviation = √(132.25)
11.50 %
So, Expected return of A is 5.5% and standard deviation is
11.50%
Market condition Prob. Return
B Prob*Return (Prob.*( return- Expected
return)^2)
Trough 0.05 2.00
0.10 0.00
Recession 0.40 2.00
0.80 0.00
Expansion 0.50 2.00
1.00 0.00
Peak 0.05 2.00 0.10
0.00
Total
2.00 0.00
Expected Return= 2.00 %
Variance of stock Investment is 0.00
standard deviation = √(0)
0.00 %
So, Expected return of B is 2% and standard deviation is
0%
