Sample Exam 1 Questions 1) Assume that there are two risky assets, A and B, that are not perfectly correlated, and that asset A has a higher mean and a higher variance than asset B. There is no riskless asset. Draw a curve that shows the means and standard deviations of portfolios that combine the two assets. On this graph, include and label the following: a) Points (labeled “A” and “B”) that show the means and standard deviations of assets A and B. b) The parts of the curve (labeled “short A” and “short B”) that can only be attained by shorting each asset. c) The point “L” representing the portfolio that has the lowest mean return that any risk- averse investor would ever choose. d) The point “50/50” that is achieved by putting 50% of your portfolio in each asset.

2) Continue to assume that the two risky assets, A and B, are not perfectly correlated. Now, however, asset A has a higher mean and a lower variance than asset B. Furthermore, assume that a riskless asset now exists, and that it’s return is less than the expected return of B (and hence less than the expected return of A). Now draw two curves that show the means and standard deviations of portfolios that combine the two assets. (You can put both curves on the same graph or use two graphs.) Draw the first curve so that the tangent portfolio contains a long position in each asset. Draw the second curve so that the tangent portfolio contains a long position in asset A and a short position in asset B. Label the locations of assets A and B and of the tangent portfolios implied by each curve.
a) Explain, in the context of the first curve, why no investor would optimally choose to put all his wealth into risky asset A. For the same standard deviation, the investor would rather invest in portfolio X, which combines an investment in the tangent portfolio with a short position in the riskless asset. The portfolio X offers the same standard deviation but a higher mean b) Which curve is consistent with a higher correlation between the two assets? In the first curve, asset B has a net positive demand, while in the second curve asset B has a negative demand. Since B has a lower mean and a higher variance, investors would only hold it if it offered major diversification benefits, or had a low correlation with asset A.

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
