Jay is reviewing his portfolio of investments, which include certain stocks and bonds. He has a large amount tied up in U.S. Treasury bills paying 3.4%. He is considering moving some of his funds from the T-bills into a stock. The stock has a beta of 1.29. If Jay expects a return of 13.5% from the stock (a little better than the current market return of 12.7%), should he buy the stock or leave his funds in the T-bill?
