Market SummaryRead ▾

Broad-based selling hit equities overnight with SPY down 1.70% and QQQ down 1.85%, but the real damage clustered in technology and utilities. Super Micro Computer's 33.3% collapse—triggered by co-founder indictment for smuggling $2.5 billion in restricted Nvidia servers to China—ignited a domino effect across semiconductors: WDC -7.5%, STX -5.4%, INTC -5.0%, and CIEN -7.0% all fell as investors reassessed supply chain risk. Utilities took parallel hits with VST -12.8%, CEG -10.9%, and NRG -9.7%, while Middle East geopolitical tensions and elevated oil prices compounded sell-off pressure across industrials (FIX -6.1%) and materials (MOS -10.0% on BofA downgrade). Profit-taking also struck momentum names: SNDK -8.1% after a 1,200% year-long surge, and IRM -5.1% following a 29% three-month rally.

Recommendation

Avoid semiconductor and AI infrastructure plays until SMCI legal clarity emerges and supply-chain concerns subside—WDC and STX face extended headwinds. Energy and utility stocks appear oversold on geopolitical noise rather than fundamentals; selective nibbling on CEG (post-antitrust divestiture clarity) and VST (despite valuation concerns) may reward contrarian buyers within 1-2 weeks. Hold broad indices; this is sector-specific bloodletting, not systemic market failure.
