Answer:
The current market rate is 8%
Step-by-step explanation:
The market rate is the return on market or the market portfolio. To calculate the market rate (rM) we will use the CAPM equation which is used to calculate the required rate of return on a stock or portfolio. The formula for required rate of return under CAPM is,
r = rRF + Beta * (rM - rRF)
Where,
- rRF is the risk free rate
- rM is the market rate
We already know the value of r, rRF and Beta. We will input these values in the above equation to calculate the market rate.
0.12 = 0.04 + 2 * (rM - 0.04)
0.12 - 0.04 = 2 * rM - 0.08
0.08 + 0.08 = 2 * rM
0.16 / 2 = rM
rM = 0.08 or 8%
