A pension fund manager is considering three mutual funds. The first is a stock fund, the second is a long-term government and corporate bond fund, and the third is a T-bill money market fund that yields a rate of 5.0%. The probability distribution of the risky funds is as follows: Expected Return Standard Deviation Stock fund (S) 11% 40% Bond fund (B) 6 20 The correlation between the fund returns is 0.16. Solve numerically for the proportions of each asset and for the expected return and standard deviation of the optimal risky portfolio.

Answer:

portfolio invested in stocks  = 73.20%

Portfolio invested in Bond = 26.80%

Expected return on optimal risky portfolio [ E(rp) ] = 9.66%

STD on Optimal Risky portfolio = 30.60%

Explanation:

Correlation between the funds return = 0.16

Determine the portfolio invested in each asset ( using excel )

expected risk premium on stock fund [ E(rps)]  = 6%

Expected risk premium on Bond fund [ E(rpb) ] = 1%

std of stock rise premium ( бs) = 40%

std on bond rise premium ( бb) = 20%

correlation between funds [ rp(sb) ] = 0.16

Variance of stock fund ( бs^2 ) = 0.16

variance of bond fund ( бb^2 ) = 0.04

Using excel formula ( as seen in the attached screen shot )

First calculate the covariance of stock and Bond fund = 0.0128

portfolio invested in stocks  = 73.20%

Portfolio invested in Bond = 26.80%

Expected return on optimal risky portfolio [ E(rp) ] = 9.66%

STD on Optimal Risky portfolio = 30.60%
