Hiro asked:
Here’s my problem:
A mutual-funds company’s newsletter says, “A well-diversified portfolio includes assets with low correlations.” The newsletter includes a table of correlation between the returns on various classes of investments. For example, the correlation between municipal bonds and large-cap stocks is 0.50, and the correlation between municipal bonds and small-cap stocks is 0.21.
a.) Rachel invests heavily in municipal bonds. She want to diversity by adding an investment whose returns do not closely follow the returns on her bonds. Should she choose large-cap stocks or small-cap stocks for this purpose? Explain your answer.
b.) If Rachel wants an investment that tends to increase when the return on her bonds drop, what kind of correlation should she look for?
This isn’t a real investing question, it’s just a problem in my homework that I have no idea how to figure out. Please help me….
