The Dow stood still while the semiconductor index alone jumped more than 3%.

October 27, 2026 · Read the Korean original

Major indices

  • Dow 52,377.57 +0.03%
  • S&P 500 7,722.60 +0.60%
  • Nasdaq 26,477.81 +1.18%
  • PHLX Semiconductor 11,445.24 +3.26%

What set the tone overnight in the US was consumer sentiment. The Conference Board's confidence index came in at 91.7, far above the roughly 81.0 the market had penciled in, while twelve-month inflation expectations eased to 5.8% but were described as still elevated. That combination, an economy holding up with price expectations refusing to bend, was read as leaving the Federal Reserve no reason to move in a hurry. With the view hardening that the Federal Open Market Committee meeting on the 27th and 28th will end in a hold at 3.75-4.00%, Treasury yields picked no direction, and CNBC reported the 10-year up by less than a basis point around the 4.995% mark. The dollar firmed slightly, and WTI fell about 1% as word of a Saudi Arabia-Iran meeting in Tehran spread hope that Middle East tensions could cool.

The indexes did not move together. The Dow rose 0.03% and effectively stood still, while the S&P 500 gained 0.60% and the Nasdaq 1.18%, and the Philadelphia Semiconductor Index jumped 3.26% on Nasdaq's own index page with all 30 members higher. That gap is the character of the session. Money did not spread across the market but crowded into a single line, AI and chips, while the Dow was held back by Boeing (BA, aircraft manufacturing), which reported third-quarter results.

Three catalysts did the lifting, and all of them concerned who funds AI. Anthropic's Nasdaq listing filing carried expectations over from the previous day, and Oracle (ORCL, cloud and databases) said it would scale its deployment of NVIDIA's (NVDA, AI accelerators) next-generation Vera Rubin servers to multi-gigawatt size while also bringing in Google TPUs and Cerebras chips. Broadcom (AVGO, networking and custom AI chips) rose on a reported financing arrangement backing some 63 billion dollars of Anthropic chip and equipment purchases, and AMD (AMD, CPUs and GPUs) climbed more than 5% during the session on an expanded AI infrastructure partnership with Meta. The other side slipped quietly. Energy lost more than 2% as crude fell, and Xylem (XYL, water infrastructure equipment), which cut its full-year guidance, dropped by double digits. With SoFi (SOFI, digital finance) and Pentair (PNR, water treatment equipment) surging on raised guidance, stocks outside AI were again sorted by their outlook alone.

Korea opens today after a session in which the KOSPI rebounded more than 3%. The overnight strength in chips is a helpful backdrop, but what decides direction is SK Hynix's third-quarter results due today. Depending on the memory outlook and the shareholder-return plan, the overnight move may or may not carry through. On the AI data-center side, power and generation equipment names including Bloom Energy (BE, fuel-cell power) rose together, leaving room for power-infrastructure expectations to revive. Cheaper crude may ease input costs for chemicals and refining, though one round of Middle East talks is hardly enough to settle the direction.

Tonight brings the Federal Open Market Committee decision and the chair's press conference, followed by big-tech earnings. The index moves, the Oracle and Broadcom announcements and the confidence reading are facts confirmed by disclosures and closing coverage, while whether this flow carries into Korean chips and power infrastructure remains the reading of the market and the press.
