AI-driven tech rebound lifts U.S. equities in Q2 2026, with the S&P 500 surging 15.4% amid lower oil prices and strong earnings.
U.S. equities rallied in Q2 2026, with the S&P 500 rising 15.4%—its strongest quarter since 2020—fueled by AI infrastructure spending and a semiconductor rebound. The Russell 3000 also climbed 15.4%, while technology stocks, initially lagging, emerged as market leaders.
The gains accelerated in late June after a U.S.-Iran peace deal reduced oil prices, easing inflation concerns. Despite economic resilience, high valuations and negative cash flow in major tech firms raised caution. The London Company Income Equity Strategy returned 12.3% for the quarter, trailing the Russell 1000 Value Index’s 13.9% gain.
Cisco Systems (CSCO) was highlighted as a key beneficiary of AI infrastructure demand, contributing to the tech sector’s outperformance. Defensive and energy sectors underperformed as investors rotated into growth-oriented stocks.
