Mr. Malone wants to change the overall risk of his portfolio. Currently, his portfolio is a combination of risky assets with beta of 1.25 and an expected return of 14%. He will add a risk-free asset (U.S. Treasury bill) to his portfolio. if he wants a beta of 1.00, what percent of his wealth should be in the risky portfolio and what percent should be in the risk-free asset? If he wants a beta of 0.75? I he wants a beta of 0.50? If he wants a beta of 0.25? Is there a pattern here?
