NEW YORK (AP) — Computer chipmakers and other winners of the artificial-intelligence boom are slumping again Thursday and weighing on stock markets worldwide. They're drowning out strength for most of the rest of Wall Street, leaving U.S. stock indexes close to flat.
The S&P 500 was virtually unchanged, a day after it pulled within 0.5% of its all-time high set last month. The Dow Jones Industrial Average was up 81 points, or 0.2% as of 10:30 a.m.
Eastern time, and the Nasdaq composite was 0.5% lower.
The majority of stocks on Wall Street rose after several of the country's biggest companies reported better profits for the latest quarter than analysts expected.
Abbott jumped 11.8% after the healthcare company delivered a fatter profit than expected and raised its forecast for earnings over the full year. UnitedHealth Group climbed 4.4% after likewise reporting better results than Wall Street expected.
But a 1% move for Nvidia's stock packs more punch on the S&P 500 than a 1% move for any other company because it's the largest on Wall Street by value.
And Nvidia fell 1.7%, making it the heaviest weight on the index. Other AI winners also sank, giving back some of their stellar gains for the year so far.
Micron Technology fell 4.1% to shave its gain for the year so far to 204%. Sandisk fell 7.4% but is still up 530% for the year so far. Western Digital sank 5.7% but is still up 181% for the year so far.
Such stocks have been under pressure for weeks because of worries that their prices shot too high and that voracious demand for computer memory and processors may not be sustainable if AI ends up not producing as much profit and productivity as promised.
The losses came even though Taiwan Semiconductor Manufacturing Co., a bellwether of the chip industry, reported a stronger profit for the latest quarter than analysts expected. Its stock in Taiwan rose 1.2%, but its stock that trades in the United States fell 1.5%.
In South Korea, drops for AI winners like Samsung Electronics and SK Hynix dragged the Kospi index down 6.4%. It’s been among the world’s shakiest markets in recent weeks because of how dominant the two AI winners are in it.
The day before, the Kospi jumped 6.2%, but it’s also had drops of 8.9%, 7.8% and 5.3% in the last two weeks.
A hike to interest rates by the Bank of Korea also weighed on stocks in Seoul, the first by the bank since 2023.
Higher interest rates can keep a lid on inflation, but they also slow the economy and hurt prices for all kinds of investments. And worries are rising that the Federal Reserve and other central banks around the world may have to raise rates to rein in the effects of expensive oil.
The price for a barrel of Brent crude rose another 0.6% to $85.43 Thursday and is near a one-month high. The Strait of Hormuz is at the center of fighting between the United States and Iran, and the worry is that oil tankers won’t be able to use it to carry crude from the Persian Gulf to customers worldwide.
That rise in oil prices helped the 10-year Treasury yield climb to 4.58% from 4.55% late Wednesday and just 3.97% before the war with Iran began.
Reports on the U.S. economy came in mixed, which added to the eddies swirling through the bond market. One report said shoppers spent less at U.S. retailers last month than economists expected. But underlying trends were perhaps more encouraging. After ignoring sales at gasoline stations, U.S. consumers remain resilient.
A separate report said fewer U.S. workers applied for unemployment benefits last week, an indication of a solid job market, while a third report said manufacturing in the mid-Atlantic region is better than economists expected.
In stock markets abroad, indexes fell across much of Europe and Asia, including drops of 1.8% in Shanghai and 2.8% in Tokyo.
Hong Kong’s Hang Seng was an outlier and rose 1.3%. Alibaba rose after China’s cyberspace regulator said Wednesday it had approved the Apple Intelligence AI tool for use in China. An Alibaba spokesperson said its Qwen model will be integrated into Apple Intelligence.
