Global Stock Markets Mixed as AI Deals Lift Tech but Broader Sentiment Sours

Major stock markets were mixed today: although deals in artificial-intelligence between companies like Amazon and OpenAI provided impetus to tech names, broader investor sentiment cooled. The NASDAQ Composite rose, but the Dow Jones Industrial Average slipped, reflecting uneven breadth. Analysts attributed the move to profit-taking after recent gains, divergence in sector momentum and concern over stretched valuations. The dollar’s strength and fading macro data also weighed as tech-driven rallies now face growth–valuation trade-offs.
