Worst-Performing S&P Composite 1500 Stocks (Ranked by January–June 2026 Performance Within Index)

The weakest performers highlight where investors chose to reduce exposure. Many of the largest declines occurred in software, information technology (IT) services and enterprise application companies—including Accenture PLC (ACN), Cognizant Technology Solutions Corp. (CTSH) and Intuit Inc. (INTU)—as investors favored businesses supplying the semiconductor, memory and data-center ecosystem. Notably, several laggards continued to report healthy revenue and earnings growth, suggesting that their declines were driven less by deteriorating fundamentals than by valuation compression and a rotation toward companies viewed as more direct beneficiaries of capital spending related to artificial intelligence (AI).
