1. Stock X has a beta of 1.60 and stock Y has a beta of 0.60. Assume the risk-free rate is 2.50% and the expected return on the market portfolio is 10.00%. Over the past ten years, stock X has had an average return of 13.65%, with a standard deviation of 41%, and stock Y has had an average return of 9.25%, with a standard deviation of 28%.
