AI and Tech Stocks Sell Off Sharply as S&P 500 Falls 4.4%

· 6 sources

AP reports the S&P 500 tumbled 4.4% in a brutal AI stock sell-off, while Bloomberg notes Treasuries rallied and CNBC says Asian chip stocks fell.

What happened

AP News reports that a brutal sell-off in AI stocks sent Wall Street reeling, with the S&P 500 tumbling 4.4%. Bloomberg says Treasuries surged as the tech-stock decline stoked demand for havens.

MarketWatch describes Wall Street voices asking whether this is the big one for the stock market as technology shares plunged. CNBC reports that the Nasdaq sell-off hit Asian chip stocks, with SK Hynix, Samsung, Softbank and TSMC all tumbling.

GuruFocus reports that Micron Technology shares plunged more than 17% amid the semiconductor selloff and labor disputes, and published a separate piece on what the 17% drop implies for the company's valuation.

Context

Government bonds are often sought by investors during sharp equity declines, which tends to push their prices up.

Why it matters

The move across AI-linked and chip stocks, including NVIDIA, Micron, AMD, Sandisk and Intel, shows how closely the sector's shares have been moving together in this episode.
