Linear Programming . 1. Define 3 variables. 2. Write a statement that tells what is to be maximized or minimized. 3. List the constraints (restrictions). 4. Label the axes. a. Graph the constraints (mostly using intercepts). b. Shade intersected areas. c. Label points of intersection as you graph. 5.

programming models have also been proposed for managing a bank's investment security portfolio, including those by Booth [1972] and Bradley and Crane [1973].

The problem is to allocate your money over available investments to maximize your final wealth. This example uses the solver-based approach.

For example, let us say that we have $10,000 that we would like to allocate. If we multiply the weights by this total portfolio value, the result will be dollar amounts of each asset. So if the optimal weight for Apple is 0.15, we need $1500 worth of Apple stock.

portfolio with 100 stocks would only require 302 terms to fully describe its distribution (100 alphas, 100 betas, 100 residual variances, plus the market return and the market variance). Compared to the more than 5000 terms of the Markowitz method, this is a big improvement.

OPTIMIZATION OF INVESTMENT 65 3. Linear Programming By means of linear programming we can optimize (maximize or minimize) a linear function of "n" variables subject to restrictions given by "m" linear equa-tions, for values of "n" larger or equal to zero. That is, it is desired to optimize the function: (1.3) Z - 71X1 + 72Xz + + YjXj + + -ynX ...

This model can be thought of as a generalization of both the least-squares and linear programming problems. QP’s are popular in many areas, such as finance, where the linear term in the objective refers to the expected negative return on an investment, and the squared term corresponds to the risk (or variance of the return).
