Rank (Models)
When adding or editing a rank-based security or submodel within a model, use Rank to enter a number from 0 to 999. The numbers do not have to be sequential. Larger numbers have greater buy priority and smaller numbers have greater sell priority. This rank gives a priority order for achieving a target.
When you create or edit a model, either a Security Level model or Allocation model, you can choose to make that model rank- or goal-based.
Goal-Based Models.Goal-based models focus on obtaining the goal position for individual securities. A goal-based model gives a definite allocation mix over time. During a rebalance, Tamarac Trading will recommend trades to get goal-based models back to these exact target allocations or as close as it can.
Rank-Based Models.Rank-based models give priority to achieving the target for the asset class or model rather than all the individual securities within the model. Once you classify a model as rank-based, you can then assign ranks—anywhere from 0 to 999—within that model. When a rank-based model is rebalanced, the targets are adjusted based on the current holdings, the rank, and the targets of the security or model. These create more model flexibility and can also be used to accommodate legacy positions and restricted securities.
