Wall Street took a nosedive late in the session on Tuesday, reversing solid gains to close deep in negative territory after President Donald Trump announced he was calling off talks on coronavirus relief legislation until after the Nov. 3 election.
All three major U.S. stock indexes closed more than 1% lower.
"The markets finally ran out of hope Speaker (Nancy) Pelosi and (Treasury) Secretary (Steven) Mnuchin would pull a rabbit out of a hat," said Chris Zaccarelli, chief investment officer at Independent Advisor Alliance in Charlotte, North Carolina.
Trump's announcement in a tweet came on the heels of U.S. Federal Reserve Chair Jerome Powell's warning of dire economic repercussions if Congress failed to pass additional fiscal stimulus.
"Powell called for Congress to act quickly and Trump effectively pulled the rug out from under that," said Oliver Pursche, president of Bronson Meadows Capital Management in Fairfield, Connecticut. "It's troubling, given the statements Chairman Powell made earlier today."
In remarks delivered online to the National Association for Business Economics, Powell warned the U.S. economy could slip into a downward spiral if the coronavirus is not contained and Congress fails to deliver additional fiscal support to businesses and households.
