Wall Street falls as Trump imposes tariffs, but not as badly as feared

The threat of a punishing trade war sent Wall Street on a rollercoaster on Monday, with indexes initially falling sharply on worries about Donald Trump’s tariffs before paring their losses after Mexico said it had negotiated a one-month reprieve.
The S&P 500 ended up falling 0.8% after Asian and European indexes logged worse drops. The Dow Jones Industrial Average lost 122 points, or 0.3%, and the Nasdaq composite sank 1.2%.
