Stocks Drop on Omicron Worries, Powell Warning

A post-Thanksgiving retreat in global stock indexes and energy prices intensified Tuesday, reflecting jitters over the impact of a new Covid-19 variant and rising inflation. 

Nearly all the stocks in the S&P 500 fell as investors pulled away from riskier assets and sought haven in government bonds. The financial, communications, industrials, consumer staples and material sectors all declined more than 2%, and all 11 sectors in the index slid at least 1%.
