Stocks fell on Friday, led by major tech shares, as Wall Street wrapped up a difficult week in which coronavirus cases rose, U.S. fiscal stimulus talks broke down and traders braced for next week’s presidential election.

The Dow Jones Industrial Average closed 157.51 points lower, or 0.6%, at 26,501.60. At one point, the Dow was down more than 500 points. The S&P 500 dropped 1.2% to 3,269.96 and the Nasdaq Composite pulled back 2.5% to 10,911.59.

The Dow and S&P 500 fell 6.5% and 5.6%, respectively, and posted their biggest weekly losses since March. The Nasdaq lost more than 5% over that time period and also had its worst one-week performance since March.

“Massive policy stimulus, positive medical developments and high hopes for a return to pre-pandemic economic activity levels have provided a solid boost to equity markets,” strategists at MRB Partners wrote in a note. “However, mounting new economic restrictions, particularly in Europe, despite being forecastable and in lagged response to the re-acceleration in COVID-19 infections, only caught investors’ attention this week, triggering sharp losses.”

In Washington, Senate Majority Leader Mitch McConnell adjourned the Senate until Nov. 9, making it highly unlikely for Democrats and Republicans to reach a deal on new fiscal stimulus before the election on Tuesday. Treasury Secretary Steven Mnuchin, meanwhile, accused House Speaker Nancy Pelosi of miscasting the state of the stalled negotiations, calling it a “political stunt.”

Traders had been betting on both sides reaching a stimulus deal before Tuesday’s vote as some recent data shows the economic recovery could stall without new aid. This is all taking place as traders prepare for choppy market moves next week amid the U.S. presidential election.

Data compiled by RealClearPolitics showed former Vice President Joe Biden holding an average lead of more than 7 percentage points over President Donald Trump. However, that lead has narrowed since early October.

The Dow, S&P 500 and Nasdaq all posted their first back-to-back monthly losses since March. The Dow lost more than 6% this month while the S&P 500 and Nasdaq each declined by more than 5% in October.

Dow futures fall 200 points amid England stay-at-home order, U.S. election uncertainty

Stock futures fell in overnight trading on Sunday amid concern rising coronavirus cases could slow the global economy.

The losses came as England adopted a stay-at-home order and as traders braced for Tuesday’s U.S. presidential election, where a contested fight for president or the Senate could delay a much-needed fiscal stimulus for the U.S. economy.

Futures on the Dow Jones Industrial Average were down by 200 points. S&P 500 futures dipped 0.6% and Nasdaq 100 futures traded 0.5% lower.
