Final answer:
The expected return for a portfolio is calculated by multiplying the return for each scenario by the probability of that scenario occurring, and then summing up these values.
Step-by-step explanation:
The expected return for a portfolio is calculated by multiplying the return for each scenario by the probability of that scenario occurring, and then summing up these values.
In this case, we have three scenarios: Bear, Normal, and Bull. The probability and return rates for each scenario are given.
Bear: Probability = 0.3, Return = -25%
Normal: Probability = 0.2, Return = 0%
Bull: Probability = 0.5, Return = 24%
To calculate the expected return, we multiply the probability of each scenario by its return rate and sum up these values:
- Bear: 0.3 * (-25%) = -7.5%
- Normal: 0.2 * 0% = 0%
- Bull: 0.5 * 24% = 12%
Adding up these values gives us:
Expected Return = -7.5% + 0% + 12% = 4.5%
