Market SummaryRead ▾

The semiconductor sector exploded overnight, with SOXL surging 18.06% as Nvidia's $2B strategic investment in Marvell (+12.6%) and multiple ecosystem partnerships (Coherent +8.2%, NXP +5.3%) reinforced AI infrastructure dominance. Broader strength followed as Trump's Iran de-escalation eased supply chain anxiety, driving gains across chip equipment (LRCX +6.5%, KLAC +6.1%, AMAT +5.3%), memory (WDC +7.1%, SNDK +9.5%), and semiconductor-adjacent plays (PLTR +6.2%, VRT +6.4%). The only notable casualty was Constellation Energy (CEG -7.5%), which disappointed with weak 2030 guidance, while McCormick (MKC -5.5%) slipped on integration concerns following its $44.8B Unilever Foods deal announcement.

Recommendation

Buy:** Overweight semiconductor equipment (KLAC, LRCX, AMAT) and AI infrastructure enablers (PLTR, VRT, LITE)—these names have genuine catalyst momentum and benefit from sustained capex cycles. **Avoid:** CEG at current levels pending clarity on long-term guidance; McCormick merger arbitrage carries execution risk. **Hold:** Broad tech (QQQ +3.31%) appears fairly valued on this relief rally; trim if positions exceed sector weighting targets, but selective AI-exposed names offer better risk/reward than the index.
