The Russell 2000 Index is a small-cap stock market index of the bottom 2,000 stocks in the Russell 3000 Index. The index is maintained by FTSE Russell, a subsidiary of the London Stock Exchange Group. The Russell 2000 is by far the most common benchmark for mutual funds that identify themselves as "small-cap", while the S&P 500 index is used primarily for large capitalization stocks. It is the most widely quoted measure of the overall performance of the small-cap to mid-cap company shares. The index represents approximately 8% of the total market capitalization of the Russell 3000 Index. As of 28 February 2017, the weighted average market capitalization for a company in the index is around $2.2 billion; the median market cap is $811 million. The market cap of the largest company in the index is almost $13.2 billion. Its first trades above the 1,000 level occurred May 21–22, 2013. Similar small-cap indices include the S&P 600 from Standard & Poor's, which is less commonly used, along with those from other financial information providers. The ticker symbol on most systems is ^RUT.
