Why are tech stocks falling?

Concerns over the timeline for returns on artificial intelligence investments and intensifying competition with China in chip manufacturing have weighed on U.S. technology shares. Investors are questioning when heavy spending by major tech companies on AI infrastructure will translate into earnings. China's accelerating advances in the semiconductor sector have also dampened risk appetite among global investors, with market participants debating whether valuations of AI-focused companies are sustainable. Leading chipmakers and cloud service providers recorded sharp losses in recent trading sessions. Analysts note that regulatory risks, alongside profit expectations for the largest technology firms, are adding pressure on share prices. The performance of U.S.-based tech companies continues to shape sentiment across other sectors in global markets.
