Micron-Led AI Rally Lifts Wall Street Into Year-End

Cooling inflation alongside Micron’s upbeat outlook boosted confidence heading into the Santa Claus window.

Overview

  • U.S. stocks rose for a second session, with the S&P 500 up about 0.9%, the Nasdaq up 1.3%, and the Dow up 0.4%, trimming earlier-week losses.
  • Micron hit a record after strong results and guidance, helping propel Nvidia, AMD and Alphabet as the AI trade regained momentum.
  • Oracle jumped after ByteDance signed binding agreements creating a U.S. TikTok joint venture that includes a 15% stake for Oracle alongside Silver Lake and MGX.
  • Nike slumped after reporting weaker margins tied to soft China sales and product mix changes, underscoring divergence with tech strength.
  • A delayed November CPI came in cooler than expected, though analysts flagged shutdown-related distortions, while traders weighed 2026 Fed easing odds, options expirations, and a BoJ rate hike to 0.75% that coincided with a weaker yen.
