Wall Street Falls on AI Bubble and Inflation Fears

Wall Street ended sharply lower on Friday, as concerns over an artificial intelligence (AI) stock bubble and persistent inflation pressures spooked investors. Technology and AI-linked stocks led the decline, prompting a rotation into more defensive sectors such as consumer staples and healthcare.

The S&P 500 fell more than 1%, while the Nasdaq Composite dropped around 1.6%, marking its steepest decline in weeks. The Dow Jones Industrial Average also slipped, though losses were more modest due to its lower exposure to high-growth tech stocks.

The sell-off was triggered by disappointing results and outlooks from major tech companies. Semiconductor giant Broadcom warned that margins could tighten despite AI-related revenue growth, reigniting fears that AI valuations may have outpaced fundamentals. Oracle’s earlier guidance also failed to impress investors, adding pressure on the sector.

Rising U.S. Treasury yields further weighed on sentiment, as some Federal Reserve policymakers expressed concerns that inflation remains too high to justify aggressive rate cuts. Higher yields make high-valuation stocks less attractive compared to safer investments, prompting investors to shift toward defensive sectors.

Market breadth weakened as declining issues significantly outnumbered advancers, reflecting broad-based selling. Even some previously strong AI and tech leaders saw sharp losses. A few stocks, such as Lululemon, bucked the trend with gains on strong profit forecasts, but these were not enough to offset the overall market decline.

Investors are now closely watching upcoming U.S. economic data, including inflation and employment figures, for indications of the Federal Reserve’s next moves. Analysts say the combination of stretched tech valuations, rising yields, and economic uncertainty has fueled caution on Wall Street.
