Multiple Choice
13.7 percent
13.3 percent
15.7 percent
14.5 percent
12.0 percent
Total Portfolio value = Value of Fund A + Value of Fund B |
=27000+33000 |
60000 |
Weight of Fund A = Value of Fund A/Total Portfolio Value |
= 27000/60000 |
=0.45 |
Weight of Fund B = Value of Fund B/Total Portfolio Value |
= 33000/60000 |
=0.55 |
std dev=( w2A*σ2(RA) + w2B*σ2(RB) + 2*(wA)*(wB)*Cor(RA, RB)*σ(RA)*σ(RB))^0.5
=(0.45^2*21^2+0.55^2*11^2+2*0.45*0.55*0.21*21*11)^(1/2)
=12.244%
sharpe ratio = (portfolio return-riskfree rate)/std dev
0.7771104=(portfolio return-2.5)/12.244
portfolio return=12%
