Stocks fell further on Wall Street Tuesday after the head of the Federal Reserve said the central bank is considering hastening a plan to ease support for the economy even as investors worry about the impact of a new coronavirus variant. The S&P 500 fell 1.8% and the Dow Jones Industrial Average fell 1.8%. Markets had opened lower after the head of Moderna told the Financial Times that he expected current vaccines would struggle with the omicron variant.
