Stack x has a 10.0 th expected return, a beta confficent of 0.9 , and a 401 standard deviation of expected refurn. Stock Y has a 12.5 th expected return, a beta coeff cient of 1.2 , and a 20. 0\% standard deviation. The risk-free rate is 6%, and the market risk prenlum is 5%.

Par aliensifdd investors the rejevant risk a measured by beta. Therdore, the stock with the bher beta is more rishy. 5tock x has the lower beta so it is moce fisky than 5 bock Y. It. for diversified inventors the felevant risk is measured by standard dev at on ol expected returnk. Therefort, the stock a th the lower standard deviation of expected retums is more risicy stock y has the ioper stahcard deviation so is is more righ thas 5 sock x : III for diversfied mvestors the cesevam tisk is meatured by beta. Therefore, the wheck whth the higher beta is less irisky. Stock Y has the higher beta so it is less risky than 5 toek x. x mere risky. Stock X Nas the higher standard deviation ao it a more ribky than 5 tock Y decimal pisces 5=
