Major stock indexes took a body blow Tuesday as wary investors pushed stocks into a massive sell-off on the heels of discouraging manufacturing data. Among the big losers was Magnificent Seven darling Nvidia, which declined more than 9% and led the sell-off in tech and chip stocks on the stock market today.
The Dow Jones Industrial Average fell 1.5%, losing 626 points in the process. The blue-chip index retreated sharply after closing at an all-time high Friday. The S&P 500 dropped 2.1%, or 119 points.
Dragged down by Nvidia, the Nasdaq's losses were harshest among the major indexes. The tech-heavy composite plummeted 3.3%, or 577 points, falling back well below its 50-day moving average. In small-cap stocks, the Russell 2000 posted a 3.2% loss.
Volume was higher on the Nasdaq and the New York Stock Exchange vs. the same time Friday. On the Nasdaq exchange, falling stocks topped rising issues by nearly 4-to-1. And on the New York Stock Exchange, losers beat gainers 3-to-1.
In the bond market, the 10-year Treasury yield fell seven basis points to 3.84%. U.S. crude oil fell 4.4% to $70.33 a barrel, as economy-sensitive assets weakened.
Nvidia Leads Market's Plunge
Nvidia lost 9.5% on the stock market today, as the artificial intelligence chip leader gave back Friday's 1.5% gain and a lot more, falling well below its 50-day line. Shares lost 7.7% last week.
After Friday's close, Nvidia formed a handle, giving it a lower buy point of 131.26, but the stock now sits about 15% below the entry and is flashing a sell signal.
Nvidia lost nearly $280 billion in market capitalization by Tuesday afternoon and was on pace for its largest one-day market cap drop ever recorded, according to Dow Jones Market Data.

Manufacturing Data Comes Up Short
Spurring the market tumble was the final August Purchasing Managers' Manufacturing Index, or PMI, from S&P Global. The reading came in at 47.9 vs. estimates for 48.0.
But it also was substantially down from the 49.6 reading in July. The decrease marks the first drop in seven months as demand has started to wane, S&P Global said.
