Approach: Think broadly. Act decisively.

Alpha is a rare commodity, but there is more than one way to mine it. Loomis Sayles’ investment teams are empowered to pursue alpha in their own distinct ways. Backed by deep proprietary research and integrated risk analysis, every team looks to take prudent risks when deep insight creates a legitimate informational or analytical edge.
