Final answer:
The expected holding-period return is 14.25% and the standard deviation of the holding-period return is 23.53%.
Step-by-step explanation:
To calculate the expected holding-period return, we need to find the weighted average of the returns in each scenario, using the probabilities that each scenario will occur. Since all three scenarios are equally likely, the probability is 1/3 for each scenario.
In the boom scenario, the return is calculated as (Dividend + End-of-year price - Stock Price) / Stock Price = (3.00 + 60 - 50) / 50 = 26%.
In the normal economy scenario, the return is (1.20 + 58 - 50) / 50 = 18.4%.
In the recession scenario, the return is (0.75 + 49 - 50) / 50 = -1.5%.
To calculate the expected holding-period return, we multiply each scenario's return by its probability and sum them up: (0.33 * 26%) + (0.33 * 18.4%) + (0.33 * -1.5%) = 14.25%.
To calculate the standard deviation of the holding-period return, we need the deviation of each scenario's return from the expected return. The deviations are: Boom: 26% - 14.25% = 11.75%, Normal economy: 18.4% - 14.25% = 4.15%, Recession: -1.5% - 14.25% = -15.75%. Square each deviation and multiply by its probability: (0.33 * 11.75%²) + (0.33 * 4.15%²) + (0.33 * -15.75%²) = 55.47%. Finally, take the square root of this value to get the standard deviation: √55.47% = 23.53%.
