Stocks are opening sharply lower on Wall Street as investors turn jittery once again in the face of rising numbers of coronavirus infections in many U.S. states and countries.
The S&P 500 finished the day down nearly 6%. The Dow Jones also finished on a sour note, losing more than 1,800 points for the day.
Stocks have been rallying over the past two months at a rate that many skeptics said was unsustainable and that didn't reflect the dire condition of the economy.
The Federal Reserve warned a day earlier that the road to recovery would be long. European and Asian markets also fell. Bond yields fell. The price of crude oil dropped 7%.
