Answer:
The reward-to-risk ratios for Stocks Y and Z are 7.22 and 5.50 percent, respectively. Since the SML reward-to-risk is 6.70 percent, Stock Y is undervalued and Stock Z is overvalued.
Step-by-step explanation:
Market risk premium is 6.7%
Reward-to-risk ratio of Stock = (Expected return of the Stock - Risk-free rate) / Beta of the Stock
Using equation (1), we therefore have:
Reward-to-risk ratio of Stock Y = (18.2% - 5.2%) / 1.8 = 7.22%
Reward-to-risk ratio Stock Z = (9.6% - 5.2%) / 0.8 = 5.50%
Since the β of the market is one, it implies that SML reward-to-risk is 6.70 perecent.
Therefore, we have:
The reward-to-risk ratios for Stocks Y and Z are 7.22 and 5.50 percent, respectively. Since the SML reward-to-risk is 6.70 percent, Stock Y is undervalued and Stock Z is overvalued.
