Question: 1. Calculate the (a) expected return, (b) standard deviation, and (c) coefficient of variation for an investment with the following probability distribution: Probability Payoff 0.45
1. Calculate the (a) expected return, (b) standard deviation, and (c) coefficient of variation for an investment with the following probability distribution:
| Probability | Payoff |
| 0.45 | 32.0% |
| 0.35 | -4.0 |
| 0.20 | -20.0 |
2. Of the $60,000 invested in a two-stock portfolio, 40 percent is invested in Stock S and 60 percent is invested in Stock X. If Stock S has a beta coefficient equal to 1.5 and the beta of the portfolio is 2.1, what is the beta coefficient of Stock X?
3. Suppose the risk-free rate of return is 4 percent and the market return is expected to be 12 percent. What is the required rate of return for a stock with a beta coefficient equal to 2.5?
Please you excel if possible.
