Security B has an expected return of 12 percent, a standard deviation of returns of 10 percent, a correlation with the market of 0.7, and a beta coefficient of 1.0. Which security is riskier? Why?.

2- An individual has \$35,000 invested in a stock which has a beta of 0.8 and \$40,000 invested in stock with a beta of 1.4. If these are the only two investment in her portfolio, what is her portfolio's beta?

3- Assume that the risk -free rate is 5 percent and the market risk premium is 6 percent. What is the expected return for the overall stock market? what is the required rate of return on a stock that has a beta of 1.2?
