The Dow Jones Industrial Average dropped 1,338.46 points, around 6.3 percent, to 19,898.92. That is the first close below 20,000 since February 2017. The Dow was even lower earlier in the day, at one point falling to levels unseen since December 2016.

The S&P 500 fell 5.2 percent. The Nasdaq Composite dropped 4.7 percent. The small cap Russell 2000 was smashed with a 10.42 percent decline, highlighting just how devastating investors think the coronavirus and social distancing will be to smaller businesses.

That could reflect a view that investors believe the rescue package will be effective, leading interest rates higher in the future.
