The Indexes

SSGA Gender Diversity Index

The SSGA Gender Diversity Index is designed to track the performance of US large-cap companies that lead their industry sectors in advancing women by promoting  gender diversity on their boards and in senior
leadership positions. This is the first index of its kind, and is a landmark on the ESG landscape.

State Street Global Advisors is currently seeking feedback on potential changes to the SSGA Gender Diversity Index. Please send any feedback you may have.

SSGA US Low-Volatility Indexes

These include the SSGA US Large-Cap Low-Volatility Index and the SSGA US Small-Cap Low-Volatility Index. The indexes are designed to track the performance of US large-and small-cap companies, respectively, that exhibit low volatility (a measure of the magnitude of movements in a stock’s price over time). This index suite applies our proprietary factor definitions, distilling years of research and experience.

US Cap-Weighted Indexes

These include the SSGA Large-Cap Index, SSGA Small-Cap Index, and the SSGA Total-Market Index. These indexes are designed to provide a comprehensive and unbiased barometer for their broad respective market segments. They are reconstituted semi-annually to ensure continued appropriate representation of each market segment. This index suite enables us to democratize investing even more by facilitating the provision of ultra low-cost funds.
