Assume that you manage a risky portfolio with an expected rate of return of 15% and a standard deviation of 29%. The T-bill rate is 5%.

Stock A	22	%
Stock B	31	%
Stock C	47	%

A client prefers to invest in your portfolio a proportion (y) that maximizes the expected return on the overall portfolio subject to the constraint that the overall portfolio's standard deviation will not exceed 20%.
