Stock Y has a beta of 1.4 and an expected return of 15.2 percent. Stock Z has a beta of .7 and an expected return of 9.1 percent. If the risk-free rate is 5.4 percent and the market risk premium is 6.4 percent, the reward-to-risk ratios for stocks Y and Z are __________ and __________ percent, respectively. Since the SML reward-to-risk is percent, Stock Y is (undervalued or overvalued?) and Stock Z is (undervalued or overvalued). (Do not round intermediate calculations.
