Self-Indexing

We provide a global suite of proprietary indexes backed by our vast resources, informed by our exceptional knowledge of indexing, and forged by a robust and methodical process.

Why Us?

Developed by an asset manager

State Street is a global titan of asset management, with more than $2.8 Trillion in AUM (as of March 31, 2019) across more than 500 different strategies. Our indexes are developed in-house and leverage 40 years of indexing heritage and the collective expertise of some 150+ professionals in 7 hubs across the globe. Indexes are not just a product to us: as a pioneer of index investing, we have extensive experience implementing them, and we understand how details like rebalance dates and frequency can erode or preserve investor wealth. We have applied this experience and provide a suite of indexes built by an asset manager for asset managers.

Methodical Process

Our indexes provide a comprehensive and unbiased barometer for their respective market segments because of the transparent, rules-based approach with which we construct them. Indexes are reconstituted at appropriate intervals to ensure continued representation of the market.

Breadth

We currently provide a broad array of factor weighted and capitalization weighted indexes, across the emerging and developed worlds, and covering the entire capitalization spectrum. We also construct focus or niche indexes that enable more-granular and targeted exposure selection. The consistent construction methodology behind our indexes ensures a perfectly modular index line-up.

The foundations of our mission do not expire. We will always pursue responsible investing as a means to enable economic prosperity and social progress. We will continue to develop proprietary indexes that adhere to this mission and embody it. To let us know your thoughts, comments, or suggestions as we do so, please email us.

The Indexes

In total, we have more than twelve investable proprietary indexes. Each of these indexes is the product of a rigorous and highly-disciplined approach to indexing built on exhaustive research and experience. Learn more about these indexes below.

SSGA Gender Diversity Index

This is the first index of its kind, and is a landmark on the ESG landscape.
