Which asset will be selected? Use an appropriate risk measure
Expected return of asset A=E= sum of (probability*return of condition)
=.1*10+.36*11+.24*9+.16*7+.09*10.2+.05*6.8 =9.498%
Variance of asset A= sum of (probability*(E-returns)^2)
=.1*(9.498-10)^2+.36*(9.498-11)^2+.24*(9.498-9)^2+.16*(9.498-7)^2+.09*(9.498-10.2)^2+.05*(9.498-6.8)^2
=2.303596
Std dev A= sqrt(variance) = sqrt(2.303596) =1.517%
--
Expected return of asset B=E= sum of (probability*return of condition)
=.14*10.1+.39*12+.21*11+.15*8+.03*7.7+.08*13=10.875%
Variance of asset B= sum of (probability*(E-returns)^2)
=.14*(10.875-10.1)^2+.39*(10.875-12)^2+.21*(10.875-11)^2+.15*(10.875-8)^2+.03*(10.875-7.7)^2+.08*(10.875-13)^2
=2.484475
Std dev B= sqrt(variance) = sqrt(2.484475) =1.576%
--
Coefficient of variation= std dev/return
coefficient of variation asset A=1.517/9.498= .1597
coefficient of variation asset B=1.576/10.875=.145
----From Coefficient of variation; lowest value asset is selected which is Asset B
