NYSEA:VTAK 23 June 2026

June 23, 2026, 9:21 AM EDT. A global sell-off in technology stocks accelerated Tuesday, with Nasdaq 100 futures down 2.8% and S&P 500 futures sliding 1.4%. South Korea's Kospi plunged nearly 10%, hit hard by memory chip giants Samsung Electronics and SK Hynix, which fell over 12%. In the U.S., chip stocks led losses premarket: Micron dropped 9%, Intel 6.7%, and others shed 5% or more. European markets followed, with ASML down 5% and the Stoxx 600 Technology index falling 3%. Market concerns center on the rising cost of AI infrastructure and potential Federal Reserve rate hikes, stalling the recent AI-driven rally. Investors rotated into defensive sectors like staples, with Walmart and Johnson & Johnson gaining. Energy markets remained stable amid a U.S. waiver on Iranian oil sanctions. Key earnings from AI chipmaker Cerebras and Micron are expected later this week.
