The characteristics of the risky funds are as follows: Expected Return Standard Deviation Stock fund (S) 20% 30% Bond fund (B) 12 15 The correlation between the fund returns is 10. 9. You require that your portfolio yield an expected return of 14%, and that it be efficient, that is on the steepest feasible CAL a What is the standard deviation of your portfolio? b. What is the proportion invested in the money market fund and each of the two risky funds? 10. If you were to use only the two risky funds and still require an expected return of 14%, what would be the investment proportions of your portfolio? Compare its standard deviation to that of the optimized portfolio in Problem 9. What do you conclude? 8. What is the Smare a MO 9.
