In previous chapters, you learned how to use Eagle Performance to analyze single period returns that are calculated and committed or loaded to any performance model with up to eight (8) groupings down to the security level. Using the Performance Analysis report, these single period returns are retrieved and used to calculate longer multi-period returns, risk statistics, and attribution.
However, there are times when you want to do analysis using a grouping for which you have not already calculated and committed returns. Dynamic Aggregated Performance Analysis allows you to aggregate single period security level performance in any grouping by changing the grouping fields in the Performance Analysis report.
In addition, all the multi-period performance, risk, and attribution capability available in the Performance Analysis report is available with Dynamic Performance. This allows you to do what-if analysis without re-running and committing historical performance for the grouping in a new Performance Model.
Since Dynamic Performance can aggregate security level performance into any new grouping, it also has the ability to "look through" a compound instrument, such as an Exchange Traded Fund, into its constituents. These constituents are then aggregated to the dynamic grouping to see a true exposure.
