Calculation of Expected Return of Cyclon:

State Return % Probability Expected Ret.(Ret.*Prob.)
Boom 18 0.15 2.7
Normal 7 0.85 5.95
Expected return of Cyclon 8.65

Calculation of Standard Deviation of Cyclon:

State Return % Expected Ret. Deviation(Ret.-Exp Ret.) Deviation2
Boom 18 2.7 15.3 234.09
Normal 7 5.95 1.05 1.1025
Total of Deviation2 235.1925
S.D.(=√Total of Deviation2) 15.335987

Calculation of Portfolio Return in Boom:

Boom (Prob 15%)
Company Return % Weight Weighted Return
Cyclone 18 0.4 7.2
Blooper 12 0.6 7.2
Portfolio Return 14.4

Calculation of Portfolio Return in Normal:

Normal(Prob 85%)
Company Return % Weight Weighted Return
Cyclone 7 0.4 2.8

State Portfolio Return % Probability Expected Ret.(Ret.*Prob.)
Boom 14.4 0.15 2.16
Normal 6.4 0.85 5.44
Expected Portfolio return 7.6

Calculation of Standard Deviation of returns of Portfolio:

State Portfolio Return % Expected Ret. Deviation(Ret.-Exp Ret.) Deviation2
Boom 14.4 7.6 6.8 46.24
Normal 6.4 7.6 -1.2 1.44
Total of Deviation2 47.68
S.D.(=√Total of Deviation2) 6.9050706

Calculatin of Portfolio Beta:

Stock Beta Weight Product(Beta*Weight)
AA 0.64 0.3 0.192
BB 1.48 0.5 0.74
CC 1.04 0.2 0.208
Portfolio Beta 1.14

Calculation of Expected return Rj (CAPM Return).:

Rj=Risk Free ret(Rf) + Beta(Risk Premium)

Rj(AA)=2.5+.64(8)

=2.5+5.12

=7.62

Rj(BB)=2.5+1.48(8)

=2.5+11.84

=14.34

Rj(CC)=2.5+1.04(8)

=2.5+8.32

=10.82
