Question: The expected returns and standard deviation of returns for two securities are as follows: Security A Security B Expected Return 0.15 0.35 Standard Deviation (STD)
The expected returns and standard deviation of returns for two securities are as follows:
Security A Security B
Expected Return 0.15 0.35
Standard Deviation (STD) 0.2 0.4
The correlation between the returns is + 0.25.
(a) Calculate the expected return and standard deviation for the following portfolios:
| Portfolio | Expected Return | STD |
| All in A |
|
|
| 0.8 in A and 0.2 in B |
|
|
| 0.5 in A and 0.5 in B |
|
|
| 0.2 in A and 0.8 in B |
|
|
| All in B |
|
|
(c) Calculate the expected return and standard deviation for the following portfolios:
| Portfolio | Expected Return | STD |
| -0.1 in A and +1.1 in B |
|
|
| -0.5 in A and +1.5 in B |
|
|
| -0.5 in B and +1.5 in A |
|
|
- Which portfolios might be held by an investor who likes high mean and low standard deviation?
- What is the expected return of the minimum Variance portfolio?
- Now assume that the correlation between the returns of the two assets is 0. Repeat the exercise. Summarize your results.
| Portfolio | Expected Return | STD |
| All in A |
|
|
| 0.8 in A and 0.2 in B |
|
|
| 0.5 in A and 0.5 in B |
|
|
| 0.2 in A and 0.8 in B |
|
|
| All in B |
|
|
| -0.1 in A and +1.1 in B |
|
|
| -0.5 in A and +1.5 in B |
|
|
| -0.5 in B and +1.5 in A |
