Editing Russell Indexes (section)

==History==
[[Seattle, Washington]]-based Russell's index began in 1984 when the firm launched its family of U.S. indices to measure U.S. market segments and hence better track the performance of investment managers. The resulting methodology produced the broad-market [[Russell 3000 Index]] and sub-components such as the small-cap [[Russell 2000 Index]]. Using a rules-based and transparent process, Russell forms its indexes by listing all companies in descending order by [[market capitalization]] adjusted for [[Public float|float]], which is the actual number of shares available for trading. In the United States, the top 3,000 stocks (those of the 3,000 largest companies) make up the broad-market Russell 3000 Index. The top 1,000 of those companies make up the large-cap Russell 1000 Index, and the bottom 2,000 (the smallest companies) make up the small-cap Russell 2000 Index.
