NEW YORK, (AFP) - Wall Street stocks plunged Wednesday on rising worries about coronavirus lockdowns as France and Germany announced tough new restrictions and US cases continued to climb.

The Dow Jones Industrial Average slumped 3.4 percent, or more than 940 points, to 26,519.95.

The broad-based S&P 500 dropped 3.5 percent to 3,271.03, while the tech-rich Nasdaq Composite Index dove 3.7 percent to 11,004.87.

French President Emmanuel Macron announced that bars, restaurants and non-essential businesses will be forced to close for at least a month, a decision that came only hours after German Chancellor Angela Merkel announced similar measures in Europe's largest economy.

The moves are certain to weigh on Europe's economy and sharpen worries that the US could follow suit in the coming weeks if cases continue to mount.

An estimate of US third-quarter GDP set for release Thursday is expected to show a historically big jump in activity compared to the second quarter, but investors are expecting much more uncertainty in the final quarter of the year.

''The strength of the economy over the summer has been vindicated,'' said FHN Financial's Chris Low. ''But the strength of the fourth quarter is very much up in the air.''

Low said investors have been disappointed with Congress's failure to enact additional stimulus. He also said investors are increasingly worried fiscal support could face obstacles after the Nov. 3 election if the vote again results in a government split between Democrats and Republicans.

While losses were broad-based, Facebook, Twitter and Google parent Alphabet all fell sharply amid a contentious Senate hearing in which Republicans accused the companies of suppressing conservative content.

Among companies reporting results, Boeing slid 4.6 percent as it reported another quarterly loss and announced another additional job cuts. The company will eliminate

another 7,000 positions, taking the two-year total to 30,000.
