An individual has $20,000 invested in a stock with a beta of 0.3 and another $60,000 invested in a stock with a beta of 2.3. If these are the only two investments in her portfolio, what is her portfolio's beta? Do not round Intermediate calculations. Round your answer to two decimal places. 6. Problem 8.07 (Portfolio Required Return) Suppose you are the money manager of a $4.66 million investment fund. The fund consists of four stocks with the following investments and betas: Stock Investment Beta $ 580,000 1.50 B 800,000 (0.50) 1,480,000 1.25 D 1,800,000 0.75 If the market's required rate of return is 12% and the risk-free rate is 6%, what is the fund's required rate of return? Do not round intermediate calculations. Round your answer to two decimal places. % 8. Problem 8.09 (Required Rate of Return) Stock R has a beta of 2.0, Stock S has a beta of 0.95, the required return on an average stock is 13%, and the risk-free rate of return is 4%. By how much does the required return on the riskier stock exceed the required return on the less risky stock? Round your answer to two decimal places. 14. Problem 8.15 (CAPM and Required Return) HR Industries (MRI) has a beta of 1.1; LR Industries's (LRI) beta is 0.5. The risk-free rate is 6%, and the required rate of return on an average stock is 13%. The expected rate of inflation built into a falls by 1.5 percentage points, the real risk-free rate remains constant, the required return on the market falls to 10.5%, and all betas remain constant. After all of these changes, what will be the difference in the required returns for HRI and LRI? Do not round Intermediate calculations. Round your answer to two decimal places. %
