Question: Excel Online Structured Activity: Expected Returns: Discrete Distribution The market and Stock J have the following probability distributions: Probability r M r J 0.3 14.00
Excel Online Structured Activity: Expected Returns: Discrete Distribution
The market and Stock J have the following probability distributions:
| Probability | rM | rJ | ||
| 0.3 | 14.00 | % | 21.00 | % |
| 0.4 | 8.00 | 5.00 | ||
| 0.3 | 20.00 | 11.00 | ||
Calculate the expected rate of return for the market. Do not round intermediate calculations. Round your answer to two decimal places = 13.4%
Calculate the expected rate of return for Stock J. Do not round intermediate calculations. Round your answer to two decimal places. = 11.6%
Calculate the standard deviation for the market. Do not round intermediate calculations. Round your answer to two decimal places.
Calculate the standard deviation for Stock J. Do not round intermediate calculations. Round your answer to two decimal places.
I was able to figure out the expected rate of return ... but not really confident on how to find the standard deviation for the market and Stock J. Please help me understand :) Thanks!
