Assume that you manage an $11.00 million mutual fund that has a beta of 1.25 and a 9.50% required return. The risk-free rate is 2.20%. You now receive another $5.00 million, which you invest in stocks with an average beta of 0.80. What is the required rate of return on the new portfolio? (Hint: You must first find the market risk premium, then find the new portfolio beta.) Do not round your intermediate calculations. a. 10.38% b. 10.63% C. 9.09% d. 8.43 8.68%
