Russell 3000 Index

Russell 3000 Index

An index, weighted for market capitalization, of the 3,000 largest publicly-traded companies in the United States. While not as famous as the Dow Jones Industrial Average or the S&P 500, some analysts believe that the Russell 3000 Index accomplishes much the same thing: providing a snapshot of how well the U.S. economy is performing by gauging demand for shares in its largest publicly-traded companies. It is managed by the Russell Investment Group. See also: Benchmark, Russell 2000 Index, Russell 1000 Index.
