Answer:
The current market rate is 8%
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,
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%
