Investment performance calculators have witnessed steady growth in functionality during the past couple of decades. Leveraging huge data management platforms that contain exception management and workflow capabilities, calculators provide upstream integration capabilities. By expanding calculation breadth to include attribution effects and risk statistics, they are knocking on front office doors. As vendor consolidation occurs and performance systems endeavor to deliver one-stop solutions, it is important to understand design mechanisms related to each functionality that drives system efficiencies. In this paper, we examine returns and ex-post risk statistics.

Refer to Part 1 of this two-part series which lists the subset of risk statistics with which we are concerned and the benefits of calculating these in a performance calculator.

This Part 2 delves into systemic factors that enable efficient computation of risk statistics and why conventional architectures encounter scaling issues.
