The stock market fell on Tuesday, with more extensive losses than investors have seen in quite a while. The Nasdaq Composite fell more than 100 points, or just over 1.6%, while the S&P 500 and Dow Jones Industrials had more modest declines. Negative comments from central bank leaders in the U.S. and Europe added to concerns about the ability of the Trump administration to move forward on its business-friendly domestic agenda, weighing down the market.
