As concerns about the stability of China’s real estate market and a brewing funding battle in the U.S. government caught fire, every major sector of the Standard & Poor’s 500 Index declined and 95 of the 100 companies listed on the Nasdaq 100 Index dropped. The Dow dropped as much as 972 points and closed at 33,970.47, down 614.41 points, or 1.8%, for the worst day since July. The S&P fell 1.7% and the Nasdaq 2.2%, the largest one-day drops for both since May. Investors were already wary that the delta variant of the coronavirus could hurt the economy, but battles in Washington over a vast spending bill proposed by Democrats and raising the government’s debt limit (to avoid a government shutdown) are compounding concerns, analysts said.
