e. Adding more such stocks will reduce the portfolio's market risk but not its unsystematic risk.
48. Which of the following statements is CORRECT? (Assume that the riskfree rate is a constant.)

50. Mikkelson Corporation's stock had a required return of 11.75% last year, when the riskfree rate was 5.50% and the market risk premium was 4.75%. Then an increase in investor risk aversion caused the market risk premium to rise by 2%. The riskfree rate and the firm's beta remain unchanged. What is the company's new required rate of return? (Hint: First calculate the beta, then find the required return.)
