Answer:
r = 0.09 or 9%
Step-by-step explanation:
Using the CAPM, we can calculate the required rate of return on a stock. This is the minimum return required by the investors to invest in a stock based on its systematic risk, the market's risk premium and the risk free rate.
The formula for required rate of return under CAPM is,
r = rRF + Beta * (rM - rRF)
Where,
- rRF is the risk free rate
r = 0.05 + 0.5 * (0.13 - 0.05)
r = 0.09 or 9%
