NEW YORK (Oct 7): U.S. stocks ended down more than 1% on Tuesday after President Donald Trump said he was calling off negotiations with Democratic lawmakers on coronavirus relief legislation until after the election.

Stocks were higher before the remarks, but reversed course after Trump made the comments on Twitter.

The S&P 500 fell to a session low shortly after the tweet, taking the index down more than 2% from its session high. Airline shares also tumbled, with United Airlines ending down 3.6% on the day, and the Cboe Volatility index climbed to a session high.

"Much of the rally we've seen in the last week in particular was based on hopes for an additional stimulus package," said Robert Phipps, director at Per Stirling Capital Management in Austin, Texas. "There's now a whole lot less reason to put money to work before the election."

Cases of the virus are still on the rise across much of the country, and hopes that a stimulus deal was still possible had helped stocks to recoup recent losses sparked by the news that Trump had contracted COVID-19.

The Dow Jones Industrial Average fell 375.88 points, or 1.34%, to 27,772.76, the S&P 500 lost 47.66 points, or 1.40%, to 3,360.97 and the Nasdaq Composite dropped 177.88 points, or 1.57%, to 11,154.60.

"Clearly the markets were pricing in some possibility of stimulus," said Chris Zaccarelli, chief investment officer at Independent Advisor Alliance in Charlotte, North Carolina.

But, he said, it was probably unlikely lawmakers would have reached a compromise with their current proposals.

Earlier in the session, Federal Reserve Chair Jerome Powell warned that the U.S. economic recovery remained far from complete.

Powell said the domestic rebound could still slip into a downward spiral if the coronavirus is not effectively controlled and growth sustained.

Consumer discretionary shares were among the biggest weights on the S&P 500, with the sector falling 2.1% on the day, but most of the major sectors were down at least 1%.

Declining issues outnumbered advancing ones on the NYSE by a 1.54-to-1 ratio; on Nasdaq, a 1.37-to-1 ratio favored decliners.

The S&P 500 posted 31 new 52-week highs and no new lows; the Nasdaq Composite recorded 114 new highs and 17 new lows.

Volume on U.S. exchanges was 10.55 billion shares, compared with the 9.79 billion average for the full session over the last 20 trading days.
