An Investment Adviser is helping a couple plan a retirement portfolio. The adviser has recommended three stocks: Allied Electronics, Bank United, and Consolidated Computers. Following are annual return and variance for each stock and the covariance between stocks:

Stock Combination (i,j)	Covariance
A,B	.4
A,C	.7
B,C	.3

Stock	Annual Return	Covariance
Allied Electronics	.14	.10
Bank United	.10	.04
Consolidated Computers	.12	.08

The couple wants a total portfolio return of at least .11. Determine the proportion of each stock to include in the portfolio to minimize the overall risk.
