Answer:
The equilibrium rate of return on this stock using the APT is 19.80%.
Step-by-step explanation:
According to given data described in the question, In order to calculate the the equilibrium rate of return using the APT, we would have to use the following formula:
E(rj) = rf + bj1RP1 + bj2RP2 + bj3RP3 + bj4RP4 + ... + bjnRPn
Therefore, Equilibrium rate of return = 8% + 0.7*8%+0.4*5%+0.6*7%
= 19.80%
The equilibrium rate of return on this stock using the APT is 19.80%.
