1. Calculate the return and standard deviation for the following stock, in an economy with five possible states. If a Boom (Probability=25%) economy occurs, then the expected return is 50%. If a Good (Probability=25%) economy occurs, then the expected return is 25%. If a Normal (Probability=20%) economy occurs, then the expected return is 15%. If a Bad (Probability=20%) economy occurs, then the expected return is 0%. If a Recession (Probability=10%) economy occurs, then the expected return is -18%. Show your work.

2. You are an investor in common stock, and you currently hold a well-diversified portfolio which has an expected return of 10 percent, a beta of 1.2, and a total value of $ 14 ,000.
