What Is Russell 2000 Index?

Stock indices are an important part of financial markets and provide information for a basket of stocks, not just one. Created in 1984, by the Frank Russell Company, the Russell 2000 index quickly became a household name. While indices like S&P 500 act as a reference point for large-capitalization stocks, Russell 2000 reflects small-cap stocks in the United States.

Russell 2000 Definition

The Russell 2000 index measures the performance of approximately 2,000 smallest-cap American companies. The index is market-cap weighted, meaning the weight of its components changes relative to the total market capitalization.

The index is operated by FTSE Russell, of the London Stock Exchange (LSE) Group. The subsidiary also maintains other indices that it should not be confused with. The Russell 3,000 index lists the largest 3,000 US companies. The largest 1,000 companies, out of these, are listed on the Russell 1,000 index. The rest, which is small/mid-caps, is a subset of the smaller components within Russell 3,000 and belongs to Russell 2,000.
