US stocks mixed; Qualcomm, Intel, Oracle surge

The divergence between the Dow and Nasdaq underscores a rotation toward AI and semiconductor names, with Qualcomm's Amazon deal and Intel's pricing strategy driving outsized moves. The market is rewarding companies with clear AI-linked catalysts, while broader indices remain tepid. Oracle's gain suggests continued appetite for AI infrastructure plays beyond chips. The key question is whether this sector-specific momentum can broaden out, or if the AI trade remains a narrow lift for select names.
