Barra Aegis System
The world's most powerful equity portfolio and risk analysis system.

To be an outstanding performer, you must take risks. But which risks will pay off? Success comes from taking the right risk at the right time. Knowing when to take risk and when to avoid it is an extremely delicate balancing act.

The Barra Aegis System helps investment professionals achieve superior performance. Combined with their intuition, skills and knowledge, portfolio managers use Aegis to better understand and manage risk and return.

Powered by Barra's industry-standard, multiple factor models, Aegis provides a framework for risk decomposition and performance attribution. By attributing risk to its common factor sources, you are able to align your strategy, allowing risk where you have confidence, and eliminating or neutralizing it where you do not.

Barra Aegis allows you to:
	Manage risk to maximize return with an in-depth understanding of the risk in your portfolio
	Consider risk, return, transaction costs and tax implications simultaneously to create optimal portfolios
	Understand sources of risk and their contribution to performance
	Leverage Barra's industry leading risk models for single, regional or global portfolios
