The Dow Jones Industrial Average retreated on Friday, with the benchmark headed for its worst week in about two years as the salvo of trade policy actions unnerved investors.

The blue-chip Dow slid 134 points, or 0.3%. The S&P 500 lost 0.5%, while the Nasdaq Composite tumbled 0.8%.

A weaker-than-expected jobs report released Friday raised further concerns about an economic softening and sent Treasury yields lower. Nonfarm payrolls increased by 151,000 jobs in February, less than the consensus forecast for 170,000 from economists polled by Dow Jones. The unemployment rate ticked higher to 4.1%.

That came as stocks have been on a roller-coaster ride this week with President Donald Trump’s tariff policies worrying investors about future U.S. growth and inflation. Trump said on Thursday that a swath of goods from Canada and Mexico that are covered by the North American trade agreement known as USMCA would be exempt from the announced duties until April 2.

That move effectively walked back much of the original plan for levies on the two countries, along with China. But the market has still sold-off this week, with uncertainty mounting amid constant updates and a lack of clarity around what to expect longer term.

“The market does not like uncertainty,” said Glen Smith, chief investment officer at GDS Wealth Management. “While we expect the market to find its footing and recover from the tariff-driven selloff, investors should brace for continued choppiness until these uncertainties clear.”

This market rout put the three major averages on course for their worst weeks this year. The Dow and S&P 500 have slid 3.1% and 4.2%, respectively, now poised to each notch their worst weeks since March 2023.

The Nasdaq Composite has dropped 4.9%, on track for its worst week going back to September. The Nasdaq is officially in correction territory, which means the tech-heavy index closed 10% off its recent high.

Treasury Secretary Scott Bessent acknowledged to CNBC on Friday that the economy could be starting “roll a bit.” However, Bessent said that was due to a transition from the policies of the previous administration. Bessent said any tariffs implemented would be a “one-time price adjustment” and not spark lasting inflation.

Financial and consumer discretionary stocks led the market down on Friday, with both S&P 500 sectors sliding more than 2%. Both are also slated to register their worst weekly performances in more than a year.
