Answer:
rE = 0.1486 or 14.86%
Step-by-step explanation:
The expected rate of return of a stock is the mean return that is expected to be earned by the stock considering the different scenarios that can occur, the return in these scenarios and the probability of the occurrence of these scenarios. The formula for expected rate of return of stock is,
rE = pA * rA + pB * rB + ... + pN * rN
Where,
- pA, pB, ... represents the probability that scenario A, B and so on will occur or the probability of each scenario
- rA, rB, ... represents the return in scenario A, B and so on
rE = 0.21 * 0.2 + 0.72 * 0.15 + 0.07 * -0.02
rE = 0.1486 or 14.86%
