NEW YORK (AP) — An early swoon shook the U.S. stock market on Friday, as Nvidia, bitcoin, gold and other high flyers swung on an increasingly antsy Wall Street, but it quickly calmed.
After starting the day with a sharp drop of 1.3%, the S&P 500 erased all of it and then meandered up and down before finishing with a slight dip of 0.1%. The Nasdaq composite flipped to a gain of 0.1%, while the Dow Jones Industrial Average trimmed its loss to 309 points, or 0.7%, after earlier being down nearly 600.
AI stocks were again at the center of the action, a day after dragging Wall Street to one of its worst drops since its springtime sell-off. Nvidia, which has become the poster child of the frenzy around artificial-intelligence technology, began the day with a loss of 3.4%. It then stormed back to a rise of 1.8% and yanked the market in its wake.
Critics have been warning that the U.S. stock market could be primed for a drop because of how high prices have shot since April, leaving them looking too expensive. They pointed in particular to stocks swept up in the AI mania. Nvidia’s stock has more than doubled in four of the last five years, for example, and the chip company is still up more than 40% for this year so far.
Even with sharp swings for the S&P 500 the last couple of weeks, the index that dictates the movements for many 401(k) accounts remains within 2.3% of its record set late last month.
“Occasional market drops are the price of the ticket for the ride,” said Brian Jacobsen, chief economist at Annex Wealth Management.
Outside of tech, Walmart edged down 0.1% after saying CEO Doug McMillon will retire in January in a surprise move. It had been down as much as 3.6% in the morning. McMillon helped the retailer embrace technology more.
All told, the S&P 500 fell 3.38 points to 6,734.11. The Dow Jones Industrial Average dropped 309.74 to 47,147.48, and the Nasdaq composite rose 30.23 to 22,900.59.
One way companies can tamp down criticism about too-high stock prices is to deliver solid growth in profits. That’s raising the stakes for Nvidia’s profit report coming Wednesday, when it will say how much it earned during the summer.
If it falls short of analysts’ expectations, more drops could be on the way. That would have a big effect on the market because Nvidia has grown to become Wall Street’s largest stock by value. That gives Nvidia’s stock movements a bigger effect on the S&P 500 than any other’s, and it can almost single-handedly steer the index’s direction on any given day.
Another way for stock prices broadly to look less expensive is if interest rates fall. That’s because bonds paying less in interest can make investors willing to pay higher prices for stocks and other kinds of investments.
