Bloomberg: Sell-off in chip stocks drags U.S. stocks to end lower this week, as AI valuation concerns weigh on market performance.

U.S. stocks closed lower this week, weighed down by the ongoing slump in chip stocks, Bloomberg reported. While a University of Michigan survey showed long-term inflation expectations came in below forecasts, easing some concerns about interest rate hikes, that failed to offset selling pressure in chip stocks. Steve Sosnick, chief strategist at Interactive Brokers, noted the S&P 500 briefly turned positive during the session before erasing gains quickly, mirroring multiple failed rebound attempts investors have seen this week. Worries over AI valuations have spread from Asian markets to U.S. trading. Two prominent Chinese hedge funds said AI stocks are in a bubble that could burst. Shares of Japan’s SoftBank Group fell after The New York Times reported OpenAI may delay its IPO until 2027. South Korea’s KOSPI index triggered a trading halt for the second time this week due to a sharp drop in chip stocks, later paring some of those losses. In the U.S., data from Bank of America showed investors pulled capital out of U.S. stocks for the first time in three months, with outflows hitting $8.5 billion. Cameron Dawson, chief investment officer at Newedge Wealth, said a key question is whether the market has the patience to wait for returns on investments from hyperscale cloud providers. Richard Reyle, chief investment officer at Questar Capital Partners, said he will not buy large-cap tech or AI stocks at current levels, as their dominance is weakening; the Magnificent Seven and Bitcoin peaked nine months ago and have yet to recover. Separately, crude oil prices extended declines as tanker traffic through the Strait of Hormuz remained steady. Brian Jacobsen, chief economic strategist at Annex Wealth Management, said the peak in energy prices is behind us, leaving room for headline inflation to cool, though price pressures have not fully vanished.
