A sell-off in shares of US technology firms has continued for a third day, dragging down all three major American stock indexes more than 2%.
Apple was the biggest loser on the Dow, falling more than 6.7%. Amazon, Facebook and Microsoft also dropped at least 4%.
The falls mark a sharp downturn from gains seen earlier in 2020, which had helped US markets rebound from losses triggered by the pandemic.
The gains had defied expectations.
The latest dip comes as the global economy is expected to shrink by roughly 5% this year. Concerns about coronavirus continue to weigh on business activity and add to trade tensions.
