Index Investing Choosing the Right Manager Matters

We've been building and managing some of the world's most successful index funds for 40 years. Our goal? To deliver cost-effective index return outcomes with no surprises or unintended biases.

Indexing is our Core

We helped pioneer the indexing category by creating institutional-caliber index funds, and today, indexed assets represent the majority of our AUM and revenues. As the investment arm of State Street Corporation—which is entrusted with 10% of the world’s assets1 —we are built to devote significant resources toward supporting evolving client needs through product development, process improvement and infrastructure enhancement. In today’s fast changing world, that commitment to continued innovation matters.
