Russell US Indexes

The modular index construction of our Russell US Indexes allows tracking of current and historical market performance by market segment or investment style.

The Russell US Indexes, from mega cap to microcap, serve as leading benchmarks for institutional investors. The modular index construction allows investors to track current and historical market performance by specific market segment (large/mid/small/microcap) or investment style (growth/value/defensive/dynamic). All sub-indexes roll up to the Russell 3000® Index.

Combining the Russell 3000® Index with the Russell Microcap® Index, the Russell 3000E® Index provides the broadest coverage of investable US equities, which includes up to the 4,000 largest US stocks by total market capitalization as of the reconstitution rank date. The Russell US Indexes can be used as performance benchmarks, or as the basis for index-linked products including index tracking funds, derivatives and Exchange Traded Funds (ETFs).

The Russell US ESG Indexes are a broad-based, alternatively-weighted US equity index family based on the Russell US Indexes. The indexes are designed to measure the performance of megacap to microcap securities that meet an improved index-level ESG profile, while maintaining similar risk/return characteristics to the underlying universe.

How to decide when to add an IPO to indexes

You might assume all indexes automatically add qualified stocks once they've gone public. However, not all indexes do. And unless a stock is included in the index, it can’t have an impact on index performance. Do you know how your index decides when to add new IPOs?
