1. You can form a portfolio of two assets, A and B, whose returns have the following characteristics:
|
Stock |
Expected Return |
Standard Deviation |
Correlation |
|
A |
10% |
20% |
 |
| Â | Â | Â |
.5 |
|
B |
15 |
40 |
 |
If you demand an expected return of 12%, what are the portfolio weights? What is the portfolio’s standard deviation?
2. Here are some historical data on the risk characteristics of Dell and McDonald’s:
| Â |
Dell |
McDonald’s |
|
β (beta) |
1.41 |
.77 |
|
Yearly standard deviation of return (%) |
30.9 |
17.2 |
Assume the standard deviation of the return on the market was 15%.
a. The correlation coefficient of Dell’s return versus McDonald’s is .31. What is the standard deviation of a portfolio invested half in Dell and half in McDonald’s?
b. What is the standard deviation of a portfolio invested one-third in Dell, one-third in McDonald’s, and one-third in risk-free Treasury bills?
c. What is the standard deviation if the portfolio is split evenly between Dell and McDonald’s and is financed at 50% margin, i.e., 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 1.41 like Dell? How about 100 stocks like McDonald’s? ( Hint: Part (d) should not require anything but the simplest arithmetic to answer.)
