U.S. stocks fell in a volatile trading session Wednesday, dragged down by news that the first known case of the Omicron variant was identified in the U.S.
All three major U.S. indexes finished lower in a stark turnaround from earlier in the day. Stocks rallied after the opening bell in an attempt to rebound from their post-Thanksgiving selloff. But the recovery reversed in the afternoon after reports that new Covid-19 infections nearly doubled in South Africa Wednesday and that the Covid-19 Omicron variant was identified in California.
