You are on the board of the Springfield College Endowment Fund (SCEF), which is evaluating two potential managers for its investments: Mr. Monty Burns (MB) and Mr. Waylon Smithers (WS). The expected returns on portfolios MB and WS are 11% and 14%, respectively. The beta of MB is 0.8 while that of WS is 1.5. The T-Bill rate is 7%, while the expected return of the market index is 12%.
