The scope of an overlay program can be narrow or broad depending on each investor’s objectives and constraints. This framework allows for seamless integration of overlay with investment staff, underlying investment managers, and other stakeholders. Overlay solutions are highly customizable; investors may choose one or more components to alleviate specific portfolio shortfalls and inefficiencies.

Investing in an overlay program involves risk. All investments are subject to loss. Learn more.
