Wall Street Ends Sharply Lower, Dow Loses 971 Points

U.S. stocks suffered steep losses Monday as U.S. President Donald Trump ramped up his attacks on Federal Reserve Chair Jerome Powell, prompting investors to worry about the central bank's independence even as they grapple with the effects of Trump's trade war.

All three major indexes tumbled, with big losses in the "Magnificent Seven" group of megacap growth stocks weighing heaviest on the tech-laden Nasdaq.

Trump escalated his criticism of Powell on Monday, saying the U.S. economy is headed for a slowdown "unless Mr. Too Late, a major loser, lowers interest rates NOW," in a bellicose Truth Social post which raised concerns over the Fed's autonomy.

"Countries that have an independent central bank grow faster, have lower inflation; they have better economic outcomes for their people," said Jed Ellerbroek, portfolio manager at Argent Capital Management in St. Louis. "And politicians trying to influence the Fed is a really bad idea, and it's very scary for the market."

The Sino-U.S. trade rift deepened after Beijing warned other countries against striking deals with the United States at China's expense, adding fuel to the spiraling tariff war between the world's two largest economies.

"Companies are ... not sure how to respond, waiting for final answers from the United States about tariff rates," Ellerbroek added. "What makes it dispiriting, I think, is the fact that this is like self-inflicted; we're in this situation by choice, by this administration's choice."

According to preliminary data, the S&P 500 lost 124.87 points, or 2.36%, to end at 5,157.81 points, while the Nasdaq Composite lost 407.77 points, or 2.50%, to 15,878.68. The Dow Jones Industrial Average fell 971.82 points, or 2.48%, to 38,170.41.
