To find the fraction of wealth to invest in Stock fund that will result in the risky portfolio with maximum Sharpe ratio the following formula to determine the weight of Stock fund in risky portfolio should be used |
Where | |||||
Stock fund | E[R(d)]= | 19.00% | |||
Bond fund | E[R(e)]= | 12.00% | |||
Stock fund | Stdev[R(d)]= | 35.00% | |||
Bond fund | Stdev[R(e)]= | 15.00% | |||
Var[R(d)]= | 0.12250 | ||||
Var[R(e)]= | 0.02250 | ||||
T bill | Rf= | 5.00% | |||
Correl | Corr(Re,Rd)= | 0.11 | |||
Covar | Cov(Re,Rd)= | 0.0058 | |||
Stock fund | Therefore W(*d) (answer a-1)= | 0.2612 | |||
Bond fund | W(*e)=(1-W(*d)) (answer a-1)= | 0.7388 | |||
Expected return of risky portfolio (answer a-2)= | 13.83% | ||||
Risky portfolio std dev (answer a-2)= | 15.12% | ||||
Sharpe ratio= | (Port. Exp. Return-Risk free rate)/(Port. Std. Dev) | =(0.1383-0.05)/0.1512 | =0.584 | ||
Where | |||||
Var = std dev^2 | |||||
Covariance = Correlation* Std dev (r)*Std dev (d) | |||||
Expected return of the risky portfolio = E[R(d)]*W(*d)+E[R(e)]*W(*e) | |||||
Risky portfolio standard deviation =( w2A*σ2(RA)+w2B*σ2(RB)+2*(wA)*(wB)*Cor(RA,RB)*σ(RA)*σ(RB))^0.5 |
