Russell 1000 Index: Guide to Large-Cap US Stocks
Understanding the Russell 1000 Index: America's largest 1,000 publicly traded companies.
What Is the Russell 1000 Index?
The Russell 1000 Index is one of the most widely recognized stock market benchmarks in the United States, designed to track the performance of the largest 1,000 publicly traded companies. This index represents approximately 93% of the total market capitalization of investable U.S. equities, making it a comprehensive measure of large-cap stock performance. The index is maintained by FTSE Russell, a subsidiary of the London Stock Exchange Group, and was officially launched on January 1, 1984. The Russell 1000 serves as a crucial performance benchmark for institutional and individual investors alike, providing insight into how the largest and most established American companies are performing in the stock market.
The index uses a market capitalization-weighted methodology, which means that larger companies have a greater influence on the index’s movements than smaller companies. This weighting system ensures that the index accurately reflects the true market value of the companies it represents. As of December 31, 2024, the stocks in the Russell 1000 Index had a weighted average market capitalization of $1.013 trillion and a median market capitalization of $15.7 billion, demonstrating the significant scale of companies included in this benchmark.
How the Russell 1000 Index Works
The Russell 1000 Index operates as a market-capitalization-weighted index, meaning each company’s influence on the index is proportional to its total market value. The price of the Russell 1000 is measured in points rather than dollars, even though the individual stocks that comprise it are measured in dollar amounts. The index price represents the weighted average of all components, so as individual stocks rise and fall, the overall index follows accordingly based on the weighting of each component.
The index is part of a broader family of Russell indexes that segment the U.S. stock market based on company size. The Russell 1000 specifically captures large-cap stocks, and it works in conjunction with the Russell 2000 Index, which tracks approximately 2,000 small-cap stocks. Together with the Russell 2000, the Russell 1000 makes up the Russell 3000 Index, which represents about 96% of the total U.S. stock market capitalization and provides comprehensive coverage of the investable U.S. equity universe.

Annual Russell Reconstitution
Each year in June, FTSE Russell conducts an annual reconstitution, also known as rebalancing, of all Russell indexes. During this process, stocks within the index are reweighted based on their updated market capitalizations. Companies may be added to or removed from the Russell 1000 based on changes in their market capitalization or other relevant factors. This annual reconstitution ensures that the index accurately reflects the current composition of the largest U.S. companies and maintains its integrity as a market benchmark.
