Solutions

Expert Solution

Expected return=weight in A*return of A+weight in B*return of B
Standard deviation=sqrt((weight of A*standard deviation of A)^2+(weight of B*standard deviation of B)^2+2*weight of A*standard deviation of A*weight of B*standard deviation of B*correlation)

1.
=0.7*0.11+0.3*0.17=0.128

2.
=sqrt((0.7*0.01)^2+(0.3*0.04)^2+2*0.7*0.01*0.3*0.04*1)=0.019000

3.
=0.7*0.11+0.3*0.17=0.128
4.
=sqrt((0.7*0.01)^2+(0.3*0.04)^2+2*0.7*0.01*0.3*0.04*0.65)=0.017384

5.
=0.7*0.11+0.3*0.17=0.128

6.
=sqrt((0.7*0.01)^2+(0.3*0.04)^2+2*0.7*0.01*0.3*0.04*0.30)=0.015601

7.
=0.7*0.11+0.3*0.17=0.128

8.
=sqrt((0.7*0.01)^2+(0.3*0.04)^2+2*0.7*0.01*0.3*0.04*0)=0.013892

9.
=0.7*0.11+0.3*0.17=0.128

10.
=sqrt((0.7*0.01)^2+(0.3*0.04)^2+2*0.7*0.01*0.3*0.04*(-0.30))=0.011942

11.
=0.7*0.11+0.3*0.17=0.128

12.
=sqrt((0.7*0.01)^2+(0.3*0.04)^2+2*0.7*0.01*0.3*0.04*(-0.65))=0.009154

13.
=0.7*0.11+0.3*0.17=0.128

14.
=sqrt((0.7*0.01)^2+(0.3*0.04)^2+2*0.7*0.01*0.3*0.04*(-1))=0.005000
