Russell 1000

Capture the complete US large cap universe

Discover the Russell 1000

It is a common misperception that two indexes covering the same market segment must be, essentially, interchangeable. But a better constructed index can enable you to capture your clients’ investment requirements with greater precision and provide you with earlier access to fast-growing stocks. How an index is constructed and maintained may sound theoretical – but the potential impact on performance is real.

Discover the difference

The Russell 1000 index is designed to be different from its competitors. Its blueprint – how it is built and how it is governed – is what sets it apart from the competition. Its distinctiveness filters down to the stocks that are included and when they are included.

Our index methodology doesn’t try to time the market or allow committees to dictate when new symbols are added to the index. The Russell methodology is rules-based and transparent, allowing asset managers and investment consultants to be confident they are truly tracking a core part of their asset allocation.
