8. Tabulate and draw the investment opportunity set of the two risky funds. Use invest- ment proportions for the stock fund of 0% to 100% in increments of 20%. What expected return and standard deviation does your graph show for the minimum-variance portfolio? (LO 6-2) 12. If you were to use only the two risky funds and still require an expected return of 12%, what would be the investment proportions of your portfolio? Compare its standard deviation to that of the optimal portfolio in the previous problem. What do you con- clude? (LO 6-4) tandard deviation of 20%, and 8.
