PORTAX Software > Inputs > Group Constraints Editor

There are two basic types of constraints: additive and relative.  An additive restriction would be to restrict the sum of all equities to be less than a constant percentage such as:


Large Cap + Small Cap + International Equity 50%


A relative restriction restricts the proportions between assets such as:


Large Cap = 2 x Small Cap


The Group Constraints Editor has 30 available constraints organized by column.   Each column has a row listing of the current assets set up in the Asset Editor.  A constraint is specified by entering a non-zero coefficient for a specific asset.  After the asset listing are the following four fields:

This is ≤, = or ≥.


This varies between 0% and 100%.


This sets which periods to apply a group constraint.


This is a notation field for a group constraint.
