The Dow Jones Industrial Average suffered a loss of 548 points Thursday after watching 830 points evaporate on Wednesday, sending the two-day decline well over 1,000 points. The Dow has now lost 5.3 percent of its value over the past two days, the most significant dip in the indicator since February 2018, the Associated Press noted.
