Answer:
Stock Y is undervalued because the reward-to-risk ratio for Stock Y is higher than the SML
Stock Z is overvalued because the reward-to-risk ratio for Stock Z is lower than the SML
Explanation:
From the question,
It is given:
FOR STOCK Y
Stock expected return = 14.7%
Stock beta = 1.4
risk-free rate is 5.2%
The Reward-to-risk ratio is given by the difference between the stock expected return and risk free rate divided by the stock beta.
Therefore
Reward-to-risk ratio for stock Y = (14.7% - 5.2%)/1.4
= 6.79%
FOR STOCK Z
Stock expected return = 8.7%
Stock beta = 0.7
risk-free rate is 5.2%
Therefore
Reward-to-risk ratio for stock Z = (8.7% - 5.2%)/0.7
= 5%
FOR SML
market risk premium = 6.2%
Risk rate = 5.2
Therefore
Reward-to-risk ratio for SML = (6.2%)/6.2 - 5.2
= 6.20%
Stock Y is undervalued because the reward-to-risk ratio for Stock Y is higher than the SML
Stock Z is overvalued because the reward-to-risk ratio for Stock Z is lower than the SML
