Suppose you live in a world in which the risk-free rate is 2%.  In this world, the portfolio with the maximum Sharpe Ratio has an expected return of 9.2% and a standard deviation of 12.5%.  An investor wants to create a portfolio in this world that pays exactly a 6% return.  What weight will the investor allocate to the optimal portfolio?  Report your answer in decimal form and round to at least 4 decimals.

Stock D has a standard deviation of 45% per year, and Stock E has a standard deviation of 60% per year.  The correlation between stock D and stock E is 0.40.  What is the covariance?  Round your answer to 4 decimal places.

You are evaluating the following portfolios, along with their expected returns and standard deviations.  Assume the risk-free rate is 3%.   Portfolio Expected Return Standard Deviation A 7% 6% B 9% 8% C 12% 10% D 14% 14% E 10% 12% Which portfolio has the highest Sharpe ratio?
