Market Summary

U.S. equities closed sharply higher on Wednesday as a wave of strong third-quarter earnings reignited enthusiasm for the AI trade and pushed technology back into a leadership role. The S&P 500 gained 44.60 points (+0.58%) to close at 7757.24, the Nasdaq Composite surged 278.04 points (+1.05%) to 26723.30, and the DJIA added 360.21 points (+0.69%) to finish at 52856.30. The Nasdaq’s outperformance reflected a broad-based rally in semiconductor, hardware, and software names, fueled by blowout results from SpaceX (SPCX) and Super Micro Computer (SMCI).

The session’s momentum was driven almost entirely by earnings catalysts rather than macro developments. SpaceX and Super Micro Computer both delivered guidance that reinforced expectations for continued heavy investment in AI computing infrastructure, lifting the PHLX Semiconductor Index by 2.0% and driving the Information Technology sector to the top of the S&P 500 standings. That strength extended into mega-caps (NVIDIA, Tesla) and industrials, while a reversal of Tuesday’s broader rotation left Communication Services, Health Care, Consumer Staples, and Real Estate in negative territory. Netflix and AT&T were notable laggards following disappointing guidance despite otherwise solid prints.

Markets briefly wobbled in the afternoon on a Reuters report that the State Department was preparing to order non-emergency personnel departures from Gulf-region embassies, which lifted crude oil and pressured equities before a State Department clarification narrowed the scope to Saudi Arabia. Stocks recovered the bulk of the dip into the close. Treasuries sold off late in the session, with yields rising modestly across the curve, while all three major averages reclaimed or held above their 50-day moving averages. With Meta Platforms and Tesla reporting after the close, attention now shifts to whether AI-driven enthusiasm can be sustained into Thursday’s session.

Key Earnings & Movers

SpaceX (SPCX) 159.28, +11.49 (+7.77%) — Strong earnings/guidance; signaled it could rent out AI compute capacity multiple times over.
Super Micro Computer (SMCI) 35.55, +3.08 (+9.49%) — Raised preliminary Q1 revenue to $18.5–$19.5 bln from prior $14.5–$15.5 bln guidance.
Tesla (TSLA) 386.47, +12.76 (+3.41%) — Rallied ahead of its after-the-close earnings report.
NVIDIA (NVDA) 221.86, +5.39 (+2.49%) — Contributed to broad AI-trade strength.
United Airlines (UAL) 101.67, +3.90 (+3.99%) — Favorable earnings reaction lifted Industrials.
Meta Platforms (META) 697.52, +3.27 (+0.47%) — Reported earnings beat after the close (per After Hours headline: “Meta Platforms jumps on earnings beat”).
Netflix (NFLX) 65.04, -3.65 (-5.31%) — Earnings beat overshadowed by weak Q4 guidance and reduced full-year ad revenue outlook.
AT&T (T) 21.91, -1.51 (-6.45%) — Beat earnings estimates but slowing subscriber growth raised competitive concerns.
Alphabet (GOOG) 330.95, -5.45 (-1.62%) — Drag on Communication Services.
Abbott Laboratories (ABT) — Traded lower on in-line Q3 results (EPS $1.42; revenue +14.5% yr/yr to $13.01 bln) but a reduced FY26 comparable sales growth outlook (~6% vs. prior 6.5–7.5%); announced plan to spin off its Nutrition business by end of 2027.

Stock Spotlight

Super Micro Computer (SMCI) was the standout mover of the session, surging 9.49% to $35.55 after issuing preliminary fiscal Q1 2027 figures that dramatically exceeded prior guidance. The company now estimates revenue of $18.5–$19.5 billion, well above its earlier $14.5–$15.5 billion range and the $14.94 billion FactSet consensus — with the $19 billion midpoint roughly 27% above both benchmarks. Gross margin guidance was also lifted to 12.0–12.5% from a prior 10.4–10.8% range, a 165-basis-point improvement at the midpoint that implies gross profit of approximately $2.33 billion versus $1.59 billion previously — a roughly 46% increase.

Management attributed the upside primarily to favorable customer and product mix rather than stronger pricing power, and the new margin estimate still sits below Q4’s 17.5% GAAP margin, meaning the update reflects sequential margin compression even as it beats expectations. The figures remain preliminary pending the November 3 earnings call, which should clarify whether the strength reflects durable demand or shipment timing, and whether SMCI’s FY27 revenue guidance of $65–$72 billion warrants revision. The update reverberated across the AI infrastructure trade, lifting related names including NVIDIA and contributing to the PHLX Semiconductor Index’s 2.0% gain.

Bond Market & Treasuries
