Summary Introduction

To calculate: The risk-free rate to the opportunity set which tangent is to be drawn. The result of the expected return and the standard deviation of the optimal portfolio are also to be determined.

Introduction: The portfolio risk is defined as the combination of assets which carries its own risk with each investment.

The standard deviation is used to determine that in which manner the values from a data set vary from its mean value. This is calculated by the square root of the variance.

standard deviation=variance

The expected return is defined as the return which is obtained on the risky asset that is expected in future.

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 8%. The probability distribution of the risky funds is as follows: Expected Return Standard Deviation Stock fund (S) 19% 34% Bond fund (B) 10 18 The correlation between the fund returns is 0.11. Solve numerically for the proportions of each asset and for the expected return and standard deviation of the optimal risky portfolio. (Do not round intermediate calculations.
