Normal 51% 10% 14% 10%
Recession 15% 4% 1% 12%

Benefits of diversification. Sally Rogers has decided to invest her wealth equally across the following three​ assets:

a.  What are her expected returns and the risk from her investment in the three​ assets? How do they compare with investing in asset M​ alone?  

Hint​: Find the standard deviations of asset M and of the portfolio equally invested in assets​ M, N, and O.

b.  Could Sally reduce her total risk even more by using assets M and N​ only, assets M and O​ only, or assets N and O​ only? Use a​ 50/50 split between the asset​ pairs, and find the standard deviation of each asset pair.

Suppose an economy has three states: boom, normal, and recession. Assume that the probability of a boom state is 0.2, a normal state is 0.5, and a recession state is 0.3. And there are three stocks in this economy, called Alpha, Beta, and Gamma respectively. The return performance of these stocks has been summarized by the following table: Alpha Beta Gamma boom 15% 28% 1% normal 6% 12% 3% recession -12% -30% 20% (Please show your intermediate processes, instead of...
