NEW YORK — December 18, 2025 — After a bruising few sessions driven by data-center financing jitters, the AI trade is finding its footing again at midday. A cooler-than-expected inflation read helped lift rate-cut hopes, while Micron’s blockbuster outlook for AI-linked memory demand reignited risk appetite across semiconductors and the broader tech complex.
