The roughly 10 percent drop in U.S. indexes yesterday was only half as bad as the daily drop on Oct. 19, 1987. The S&P 500 is back to where it was in January 2019. His approval rating tends to move in line with the markets, an association that he often encourages. In mid-February, the S&P 500 was up nearly 60 percent since the 2016 election and 50 percent higher than the day of Mr. Trump’s inauguration. Now, the index is 16 percent higher than Election Day and 9 percent above inauguration levels.
