How major US stock indexes fared Wednesday

Major U.S. stock indexes closed essentially flat Wednesday after an early rebound rally faded in the final minutes of trading.

The topsy-turvy day came as health authorities around the world take steps to monitor and contain a deadly virus outbreak in China to keep it from spreading globally.

Gains in technology, financial and health care stocks were offset by losses in industrial, energy, real estate and other sectors. Bond yields rose.
