The Russell 2000 tracks the 2,000 smallest companies in the Russell 3000 Index, making it the premier benchmark for U.S. small-cap stocks.

Why It Matters

Small-cap companies are more domestically focused than large-caps, so the Russell 2000 is a better indicator of the U.S. domestic economy. These companies derive the majority of their revenue from within the United States.

Rate Sensitivity

Small caps tend to carry more debt relative to their size, making them highly sensitive to interest rate changes. Rate cuts disproportionately benefit Russell 2000 companies.

Market Impact

Russell 2000 outperformance signals a broadening rally and healthy domestic economy. Underperformance suggests narrow market leadership (a "top-heavy" market led by mega-caps).
