The closing numbers: U.S. stocks suffered their worst session since the April 2025 tariff crash on Thursday. The S&P 500 fell 334.89 points, or 4.36%, to 7,353.73. The Dow Jones Industrial Average dropped 1,833.06 points, or 3.44%, to 51,523.06, wiping out Wednesday's 1,569-point post-midterm surge. The Nasdaq Composite plunged 1,421.52 points, or 5.52%, to 24,315.00, closing in correction territory and below its 200-day moving average. The small-cap Russell 2000 lost 4.45%.
The driver – an AI trade unwind: Investors dumped 2026's biggest AI winners as hedge funds rushed to lock in gains before year-end, while the Democrats' sweep of Congress raised regulatory concerns over AI data-center buildouts. The PHLX Semiconductor Index collapsed 12.25%, its worst day in years, and Nomura strategist Charlie McElligott described the selling as "shooting the generals." Retail investors joined in, selling a net $358 million in individual stocks by mid-afternoon, according to Vanda Research — on track for their biggest net-selling day since March 2020. Oil added to the pressure, with WTI crude near $90 and Brent near $98 per barrel amid uncertainty over a U.S.-Iran deal.
Chipmakers: Nvidia, Micron and AMD led the rout. AMD fell about 15% during the session even as CEO Lisa Su told Yahoo Finance the market was being "a little bit short-sighted" about AI demand.
SpaceX and Tesla: Both Elon Musk-led companies dropped more than 9% during the session as Democratic wins in Washington and Texas raised doubts about a potential merger and data-center expansion.
AI software: Palantir and CrowdStrike each fell more than 10% at their lows, with Cloudflare, Oracle and Palo Alto Networks also sharply lower, while Salesforce and Adobe were little changed.
주요 지수: 11월 5일(목) 뉴욕 증시는 2025년 4월 관세 충격 이후 최악의 하루를 기록했습니다. S&P 500은 334.89포인트(4.36%) 내린 7,353.73, 다우존스 산업평균지수는 1,833.06포인트(3.44%) 급락한 51,523.06으로 전날의 1,569포인트 중간선거 랠리를 모두 반납했습니다. 나스닥 종합지수는 1,421.52포인트(5.52%) 폭락한 24,315.00으로 마감하며 조정 국면(고점 대비 10% 이상 하락)에 진입했습니다.
하락 원인: 연말을 앞두고 헤지펀드들이 올해 수익을 확정하기 위해 AI 주도주를 대거 매도했고, 민주당의 의회 장악으로 AI 데이터센터 규제 우려가 커졌습니다. 필라델피아 반도체지수는 12.25% 폭락했으며, 개인 투자자들도 2020년 3월 이후 최대 규모의 순매도에 나섰습니다. 국제유가는 미-이란 협상 불확실성 속에 WTI 배럴당 약 90달러로 올랐습니다.
주요 종목: 엔비디아·마이크론·AMD 등 반도체주가 급락을 주도했고 AMD는 장중 약 15% 하락했습니다. 스페이스X와 테슬라는 합병 및 데이터센터 확장에 대한 규제 우려로 장중 9% 넘게 떨어졌으며, 팔란티어와 크라우드스트라이크도 장중 10% 이상 하락했습니다.
