US stocks fall as another bumpy week of trading nears end

Stocks are falling in afternoon trading on Wall Street Friday, as another zig-zag week for markets closes out following an abrupt loss of momentum this month.

The S&P 500 was down 1.3%, on pace for its third straight weekly loss.

The Dow Jones Industrial Average fell 295 points, or 1.1%, to 27,608, as of 2:29 p.m. Eastern time, and the Nasdaq composite slid 1.5% after initially eking out a gain earlier in the day. Smaller stocks also fell, with the Russell 2000 index of small caps down 0.9%.

Analysts warned that the day’s trading could be even bumpier than usual. Futures and options on stocks and indexes are set to expire in an event known as “quadruple witching,” which can drive swings in prices.

Stocks have swirled this week despite the Federal Reserve’s saying it expects to keep short-term interest rates at record lows through 2023. Low rates typically turbocharge the market by encouraging investors to pay higher prices for stocks, but some investors may have been looking for the Fed to be even more aggressive.

Growth in some areas of the economy has also slowed after unemployment benefits and other aid from the federal government expired, and partisan disagreements in Congress are holding up a possible renewal of support. Investors say it’s essential that such aid arrives.

“To the extent that you don’t get an additional fiscal cushion, the economy is going to be impacted by it,” said Brian Levitt, global market strategist at Invesco.

Rising tensions between the world’s two largest economies are also continuing to keep markets on edge. The United States said on Friday that it will ban downloads of the Chinese apps TikTok and WeChat on Sunday. It cited national security and data privacy concerns.

President Donald Trump’s targeting of the Chinese tech industry has caused intermittent worries in the market about a possible retaliation against the U.S. industry.

Big Tech stocks already stumbled sharply this month on worries that their prices have grown too expensive following their virtuosic performance through the pandemic. Surging shares of Apple, Microsoft, Amazon and others helped carry Wall Street back to record heights, even as the pandemic walloped much of the economy, as the coronavirus accelerated work-from-home and other trends that benefit them.

But they suddenly lost momentum two weeks ago, causing the market to swing with them. Because these companies have grown so massive, their stock movements have huge sway over broad market indexes, such as the S&P 500.

“We certainly got a little short-term overbought and we headed into a time of the year that is not great for markets,” Levitt said.

On Friday, several Big Tech stocks continued slipping. Apple was down 2.4%, and Microsoft fell 2%.

Also on the long list of concerns for markets is how the pandemic progresses, whether a vaccine for COVID-19 could indeed be available in early 2021 as many investors expect and what November’s U.S. presidential election will do to the economy.

Treasury yields remain very low, showing the powerful strength of the Federal Reserve and continued expectations by bond investors for only modest economic growth and inflation. The yield on the 10-year Treasury slipped to 0.68% from 0.69% late Thursday.

A preliminary report on Friday said that consumer sentiment is improving at a faster pace than economists expected, which is key for an economy where spending by consumers is the main driver. But it follows other reports this week that showed growth in retail sales slowed last month and the number of layoffs across the country remains stubbornly high.

Other stock markets around the world made mostly modest moves.

In Europe, the German DAX lost 0.7%, and the French CAC 40 sank 1.2%. The FTSE 100 in London fell 0.7%. Markets in Asia closed mostly higher.

Benchmark U.S. crude oil fell 0.2% to $40.89 to per barrel. Brent crude, the international standard, fell 0.8% to $42.95 per barrel.
