Small- and Micro-Cap Stay at the Head of the Class in the Second Quarter

In the bullish second quarter of 2026, small- and micro-cap stocks continued to lead the US equity markets in a robust period for equities of all sizes and styles. Resilience amid mixed signals was once again the main theme, as geopolitical tensions remained unresolved, inflation lingers, and energy prices are still volatile, depending on the changing state of the war with Iran on any given day. On the plus side, the economy was still in solid shape. Consumers were spending, even as they reported lower confidence in economic growth, while the AI buildout continued to gain momentum (though not without controversies of its own, most notably around the enormous amount of energy needed to power data centers).

Against this backdrop, US, stocks roared back from the low or negative returns in 1Q26. For the second quarter, the Russell 2000 Index rose 21.5%, and the Russell Microcap Index gained 25.6%, versus respective gains of 15.1% and 10.7% for the large-cap Russell 1000 Index and mega-cap Russell Top 50 Index. (The tech-heavy Nasdaq Composite was up 21.6% for the same period.)

In a Bullish Quarter, Small- and Micro-Cap Remained in Front

Small- and micro-cap leadership also encompassed longer-term periods. For the year-to-date period ended 6/30/26, the Russell 2000 advanced 22.6%, while the Russell Microcap increased 27.5% compared to a gain of 10.3% for the Russell 1000 and 2.0% for the Russell Top 50. For the one-year period ended 6/30/26, the Russell 2000 was up 40.8%, the Russell Microcap gained 58.5%, the Russell 1000 was up 22.0%, and the Russell Top 50 returned 16.3%.
