Note: It's more commonly just referred as "pag" or the "portfolio analytics group."  I don't think I've met anyone who's casually referred to it as "the PEH-AY-GEE" unless they were spelling out loud.  Well, this is just from the website.

Portfolio Analytics Group (PAG)

The Portfolio Analytics Group is a risk management and analytics group in BlackRock that utilizes sophisticated analytics within our fixed income, equity and alternatives businesses to help our clients and portfolio managers achieve good portfolio risk-adjusted returns. PAG provides the daily risk management measurement and reporting and ad-hoc analytical support to over $5 trillion worth of assets under risk management across thousands of portfolios. Analysts will gain a broad understanding of the asset and risk management business which includes: learning about the wide range of securities our clients trade, how they are priced in the market, how we analyze them within BRS and what sensitivities they have to various market factors. The group is also responsible for developing, maintaining and enhancing the technology that is used to support the trading and reporting needs of BlackRock Solution’s risk management clients.
