Portfolio risk Here are some historical data on the risk characteristics of Bank of America and Starbucks:
Assume the standard deviation of the return on the market was 23.0%.
- a. The correlation coefficient of Bank of America’s return versus Starbucks is .30. What is the standard deviation of a portfolio invested half in each share?
- b. What is the standard deviation of a portfolio invested one-third in Bank of America, one-third in Starbucks, and one-third in risk-free Treasury bills?
- c. What is the standard deviation if the portfolio is split evenly between Bank of America and Starbucks and is financed at 50% margin, that is, the investor puts up only 50% of the total amount and borrows the balance from the broker?
- d. What is the approximate standard deviation of a portfolio composed of 100 stocks with betas of 1.57 like Bank of America? How about 100 stocks like Starbucks? (Hint: Part (d) should not require anything but the simplest arithmetic to answer.)
