Answer:
The new required rate of return is 14.38%
Explanation:
The old required rate of return was 11.75%.
Using the SML equation and plugging in the known components, we will calculate the beta for the stock.
0.1175 = 0.055 + β * 0.0475
(0.1175 - 0.055) / 0.0475 = β
β or beta = 1.316
The same equation will be used to calculate the new required rate of return.
The beta and risk free rate are same.
The new market risk premium is 6.75% (4.75 + 2)
The new required rate of return (r) is,
r = 0.055 + 1.316 * 0.0675
r = 0.14383 or 14.383%
