Stocks are falling again on Thursday as the economic impact of the global coronavirus spread becomes clearer.

The Dow was down more than 825 points, or about 3%, to around 26,265, at mid-day Thursday. The S&P 500-stock index declined around 2.8.% and the tech-heavy Nasdaq composite dropped 2.3%, erasing more than half their gains from Wednesday’s rally.

The Institute of International Finance predicted that U.S. economic growth would slow to 1.3% this year and that global expansion could hit its lowest level since the 2008 financial crisis.
