US Micro Cap stocks show potential despite Russell 2000 decline

After a period of significant gains, smaller US-listed companies have faced recent pressure. The Russell 2000 index experienced a notable decline in September, falling below its August record high due to the macroeconomic environment and the continued dominance of large technology corporations.

Despite this recent weakness, market observers from Royce Investment Partners, a Franklin Templeton subsidiary, suggest that micro caps remain attractive due to low relative valuations and rising earnings. Data shows that micro caps significantly outperformed both small and large caps during much of 2026. For instance, from the market low in April 2025 to the end of June 2026, the Russell Microcap Index rose by 108.4 percent, compared to 74.5 percent for the Russell 2000 and 52.8 percent for the Russell 1000.

Growth in the micro cap segment has been driven largely by the technology sector, specifically semiconductors, semiconductor equipment, biotechnology, banking, and software.
