Market Close – Wednesday, October 21, 2026

U.S. stocks rose across the board on Wednesday as SpaceX's quarterly results reignited enthusiasm for the AI trade just ahead of Big Tech earnings. The S&P 500 gained 0.58% (+44.60) to close at 7,757.17, the Dow Jones Industrial Average added 0.69% (+360.21) to 52,856.09, and the tech-heavy Nasdaq Composite jumped 1.05% (+278.04) to 26,702.86, led by chipmakers.

What Drove the Market

SpaceX lifts the AI trade. SpaceX's AI-fueled quarterly results sparked a rally in AI-linked names, with Nvidia and AMD both moving higher and the Nasdaq-100 outperforming the broader market. Investors are also positioning for Tesla and Meta, which report after Wednesday's close to kick off Big Tech earnings season. Stocks largely shrugged off an afternoon jump in oil: Brent crude climbed toward $110 a barrel after Saudi Arabia reported an attack on an Aramco oil field in its Eastern Region.

Notable Movers

SpaceX (SPCX) +7.8% — Shares surged after quarterly results, and Elon Musk said SpaceX and Tesla have each formed special committees to discuss a potential merger. Tesla (TSLA) rose 3.4% to $386.47 ahead of its own earnings.

Netflix (NFLX) about -5% — The streamer's fourth-quarter revenue forecast of $13.44 billion missed estimates, and it cut 2026 ad revenue guidance from $3 billion to $2.7 billion.

AT&T (T) about -6% — The carrier fell after third-quarter postpaid phone additions came in below estimates amid concerns over SpaceX's Starlink mobile ambitions. Elsewhere, Super Micro Computer (SMCI) jumped as much as 12% after raising its quarterly revenue forecast by $4 billion, and cybersecurity stocks rallied 5-7% after emergency patches for a critical PHP flaw.

한국어 요약

10월 21일(수) 미국 증시는 일제히 상승 마감했습니다. S&P 500 지수는 0.58%(+44.60) 오른 7,757.17, 다우존스 산업평균지수는 0.69%(+360.21) 오른 52,856.09, 기술주 중심의 나스닥 종합지수는 1.05%(+278.04) 오른 26,702.86에 장을 마쳤습니다.

상승 요인: 스페이스X의 AI 사업 호조가 담긴 분기 실적이 AI 관련주 투자 심리를 되살렸고, 엔비디아·AMD 등 반도체주가 나스닥 상승을 이끌었습니다. 장 마감 후 테슬라와 메타의 실적 발표를 앞두고 기대감도 커졌습니다. 사우디 아람코 유전 피격 소식으로 브렌트유가 배럴당 110달러 가까이 올랐지만 증시에 미친 영향은 제한적이었습니다.

주요 종목: 스페이스X는 실적 발표와 함께 일론 머스크가 테슬라와의 합병 논의를 위한 특별위원회 구성을 밝히면서 약 7.8% 급등했고, 테슬라도 3.4% 올랐습니다. 넷플릭스는 4분기 매출 전망이 예상치를 밑돌고 광고 매출 가이던스를 하향하면서 약 5% 하락했으며, AT&T는 가입자 증가 부진과 스타링크 경쟁 우려로 약 6% 떨어졌습니다. 슈퍼마이크로는 매출 전망 상향으로 한때 12% 급등했습니다.
