How major US stock indexes fared Thursday

By The Associated Press

U.S. stocks spun lower in a dizzying day of trading Thursday as worries about the viral outbreak that started in China knocked the S&P 500 off its record high.

The market started the day higher following another round of stronger-than-expected reports on the U.S. economy, but it slumped suddenly in the late morning only to pare its losses later.

Market watchers didn’t see one clear trigger for the movements, which were reminiscent of the market’s sudden shifts during the height of the U.S.-China trade war. Several companies warned of the hit to profits they’re expecting due to the virus.

The S&P 500 index fell 12.92 points, or 0.4%, to 3,373.23.
