Expected Return of assetA=R1 | 1% | |||||||
Expected Return of assetB=R2 | 1% | |||||||
S1=Standard Deviation of assetA | 1% | |||||||
S2=Standard Deviation of assetB | 1% | |||||||
Variance of asset A=V1 | 1 | %% | ||||||
Variance of asset B=V2 | 1 | %% | ||||||
Correlation between asset A and B=Corr(1,2) | -0.25 | |||||||
Covariance(1,2)=Cov(1,2)=Corr(1,2)*S1*S2=0 | -0.25 | %% | ||||||
w1=Investment in asset A | ||||||||
w2=Investment in asset B | ||||||||
Portfolio Return=Rp(Percentage) | ||||||||
w1*R1+w2*R2=w1*1+w2*1=w1+w2 | ……..Equation (1) | |||||||
Vp=Portfolio Variance=(w1^2)*V1+(w2^2)*1+2*w1*w2*(-0.25) | ||||||||
Vp=Portfolio Variance=(w1^2)*+(w2^2)-0.5*w1*w2….....Equation(2) | ||||||||
