Abstract: On the basis of Markowitz mean-variance model, we put f or ward the balanced theory of portfolio profit rate maximization on t he condition that difference coefficient σ/μ is minimized. Using Lag range parameter method, we gain the feasible portfolio decision. At last we give an example analysis.

Key words: difference coefficient σ/μ, balanced thoery, Lagrange multiplier method, portfolio
