U.S. stock futures paused Wednesday as investors parsed the latest headlines on the Omicron variant amid thin trading in the final days of the year.
Futures tied to the S&P 500 added less than 0.1% after the broad-market index closed down 0.1% on Tuesday but still notched its second-highest closing level. Nasdaq-100 futures climbed 0.1%, suggesting muted gains for technology stocks after the opening bell. Dow Jones Industrial Average were flat.
