What is Russell 2000?

Russell 2000 Index

Quick Answer

The Russell 2000 is an index that measures the performance of 2,000 small-cap companies in the United States. It is widely used to gauge the health of the small-cap segment of the stock market and reflects the economic conditions affecting smaller businesses.

Overview

The Russell 2000 is a stock market index that represents 2,000 small-cap companies in the U.S. It is part of the broader Russell 3000 Index, which includes the 3,000 largest U.S. stocks. Investors and analysts look at the Russell 2000 to understand how smaller companies are performing compared to larger ones, as these smaller firms can be more sensitive to economic changes. Small-cap companies, which make up the Russell 2000, typically have a market capitalization between $300 million and $2 billion. These companies often have more growth potential but can also carry higher risks compared to larger, established firms. For example, a small tech startup that is gaining traction in its market may be included in the Russell 2000, and its performance can significantly impact the index. The importance of the Russell 2000 lies in its ability to provide insights into the overall economy. When the index is performing well, it often indicates that small businesses are thriving, which can lead to job creation and economic growth. Conversely, a decline in the Russell 2000 may signal challenges for smaller companies, reflecting broader economic issues that could affect investors and consumers alike.
