Russell U.S. Indexes
A complete U.S. stock market view
Russell U.S Indexes are the leading U.S. equity benchmarks for institutional investors¹. Our broad range of U.S. indexes allow investors to track current and historical market performance by specific size, investment style and other market characteristics.
Since launching our research-based U.S. indexes in 1984, we continue to create products that give investors an edge in the complex investment universe.
In 1987, based on research showing that major investing styles move in and out of favor over time, we developed separate benchmarks for tracking growth and value stocks. This groundbreaking innovation has now become industry standard. Today, Russell is a leading provider of comprehensive equity style indexes.
Comprehensive and representative.
Russell's U.S. Indexes cover 98% of the U.S. equity investable universe and include companies determined to be part of the U.S. equity market according to Russell's robust country classification methodology.
Transparent and rules-based.
Modular design makes Russell indexes practical and easy to use for both active and passive managers.
Industries and sectors are represented by a wide variety of securities, rather than samples found in other indexes.
Indexes are updated quarterly and rebuilt annually to ensure that securities are included in the appropriate market cap and style index.
Many elements of Russell's index methodology are now considered industry standard, including float adjustment and multi-factor style.
