Portfolio Aggregate

Portfolio Aggregate (PA) is in principle a regular portfolio, with positions being the sum of positions of the constituent portfolios. PA stores the breakdown of positions by constituent portfolios, rather than simply adding the securities up. Furthermore, PA remains “linked” to its constituent portfolios, meaning that a change to a constituent portfolio would automatically be reflected in the PA. The scope of uses is very wide and depends on the type of institution and objectives of the analysis. Pension funds could upload all its portfolios and then have an aggregate view in terms of breakdown by mandates or individual managers. Asset managers could see aggregate exposure to specific countries, sectors or currencies, and overall risk. A private bank would have an immediate snapshot of all its accounts etc.
