How to Max portfolio gap and Min the portfolio gap daily stdev?!

[hellohere]

Say here are 100 trading days, and here are 20 winning portfolios with daily return 0.25%(100.25)

and two losing portfolio with daily return -0.25%(99.75). 

How to find the optimal portfolio (Winner-Loser) with the max return (Winer-Loser) and the min

daily volatility?!

Though this a a theoretical problem, how to simulate the solution?!

Hello,

I have moved your post to this board 

--> [ Mathematical Optimization, Discrete-Event Simulation, and OR
        Operations Research topics: SAS/OR,
        SAS Optimization, and SAS Simulation Studio ]

as it is more about optimization than about Forecasting and Econometrics (the board where you originally posted).

Start here :

SAS/OR User's Guide: Mathematical Programming
The Quadratic Programming Solver
Example 11.2 Portfolio Optimization
