1. Explain how differences in allocations between the risk-free security and the market portfolio can determine the level of market risk.

2. Based on the probability and percentage of return for the three economic states in the table below, compute the expected return.

Economic State Probability Percentage of Return
Fast Growth 0.10 60
Slow Growth 0.50 30
Recession 0.40 -23

3. If the risk-free rate is 7 percent and the risk premium is 4 percent, what is the required return?
4. Suppose that the average annual return on the Standard and Poor's 500 Index from 1969 to 2005 was 14.8 percent. The average annual T-bill yield during the same period was 5.6 percent. What was the market risk premium during these 10 years?
5. Conglomco has a beta of 0.32. If the market return is expected to be 12 percent and the risk-free rate is 5 percent, what is Hastings' required return? Use the capital asset pricing model (CAPM) to calculate Conglomco's required return.
6. Calculate the beta of a portfolio that includes the following stocks:
- Conglomco stock, which has a beta of 3.9 and comprises 35 percent of the portfolio.
- Supercorp stock, which has a beta of 1.7 and comprises 25 percent of the portfolio.
- Megaorg stock, which has a beta of 0.3 and comprises 40 percent of the portfolio.

#### Solution Preview

1) A risk-free security has zero risk, i.e. Beta = 0. A market portfolio has market risk, i.e. Beta = 1. By observing the differences in the allocations between the risk-free security and market portfolio, the level of market risk can be determined. For example, if 25% of the market is invested in risk-free securities, while 75% of the portfolio is invested in the market, then the portfolio will have Beta = 75%.

2) Expected return = (probability of Fast Growth * % Return of Fast ...
