NEW YORK (AP) — More drops for artificial-intelligence stocks are hitting Wall Street Thursday, but gains for the rest of the market are keeping U.S. indexes near their records.
The S&P 500 was virtually unchanged in midday trading after erasing an early loss. The weakness for AI stocks dragged the Nasdaq composite down 0.4%, but the Dow Jones Industrial Average was up 440 points, or 0.9%, as of 11 a.m. Eastern time as the majority of U.S stocks climbed.
The sharp drops for AI stocks began on Wall Street Wednesday and then whipped around the world to send South Korea’s Kospi down 7.6% and Japan’s Nikkei 225 down 4.9% before returning to the United States.
It’s their latest stunning swing after they led the market for years. Companies are pouring money into AI in hopes of bigger profits and improved productivity. But data centers and AI chips cost money, and many companies have been borrowing the cash to get them.
Now, after yields in bond markets worldwide hit their highest levels in years, worries are rising about how resilient that boom in spending can be. Many AI-related companies have already taken on debt to build out their aspirations, and stocks are struggling under the debt loads.
CoreWeave, which offers AI computing power to customers over the cloud, fell 5.2% a day after tumbling 15.5%. It said in the summer that it had $4.41 billion in principal payments to make on its debt over the second half of this year and another $6.18 billion in 2027. It had more than $5.5 billion in cash, as of June 30.
High yields in the bond market also generally make investors less willing to pay high prices for stocks, particularly those seen as the most expensive.
Nvidia, the chip company that’s ridden the AI boom to become Wall Street’s most valuable company, fell 1.9% and was the day’s heaviest weight on the S&P 500. It came into the day with a nearly 1,415% gain since the end of 2022.
The losses came despite a strong profit report from a bellwether of the AI industry. Taiwan Semiconductor Manufacturing Co. reported a profit for the latest quarter that topped analysts’ high expectations, and Chief Financial Officer Wendell Huang said it expects strong demand to continue in the final three months of 2026.
Its stock that trades in the United States fell 2.6%.
A day earlier, another major player in the AI industry likewise delivered a strong profit report that failed to stir excitement for the industry. Christophe Fouquet, the CEO of ASML in the Netherlands, said demand has been so strong because of AI that some customers are talking about placing orders for as far out as 2029 or even 2030.
Outside of AI, stocks were more resilient.
Marsh & McLennan climbed 6.4% to help lead the market after the insurance and professional services firm reported a stronger profit for the latest quarter than analysts expected. The company, which updated its brand name to Marsh early this year, also delivered higher revenue than expected.
Expectations are high for profits at all kinds of companies this reporting season, which began in earnest this week. Companies will need to surpass them to keep driving their stock prices to more records when high inflation and many other worries are weighing on Wall Street.
Seven out of every 10 stocks within the S&P 500 rose. But because AI stocks have become so big in market value, their stock movements have more effect on the index and can drown out the rest of the market.
Treasury yields fell in the bond market on Thursday, which means investors are willing to pay higher prices to buy U.S. government bonds. Treasurys have a reputation as a safer investment, one with less risk of the borrower going bankrupt, and investors often flock to them when feeling nervous.
The yield on the 10-year Treasury fell to 5.07% from 5.19% late Wednesday. It had topped 5.30% earlier this month and touched its highest level since 2002 because of worries about high inflation, signals of a strong U.S. economy and other factors.
The drop in yields came even though another report signaled inflation has worsened by even more in the United States than economists expected.
Several reports on the U.S. economy also came in stronger than economists expected, which typically push yields upward. One report said U.S. retailers made more money last month than economists expected, while another said fewer U.S. workers applied for unemployment benefits last week than expected.
In stock markets abroad, South Korea’s loss was the headliner. Its Kospi index is dominated by two chip companies, Samsung Electronics and SK Hynix, and it fell to its worst day since July. It has dropped 39% since setting a record in June.
Indexes were stronger in Europe, and London’s FTSE 100 rallied 1.1% for one of the world’s biggest gains.
