Internet reports that as Trump's latest tariffs approach, the U.S. stock market is facing a potentially fragile moment. The S & P 500 index has fallen about 5% from its historical closing high on February 19. A series of weak economic reports in the United States have raised concerns about economic growth, and tariffs have added to the market outlook. Analysts generally believe that imposing tariffs on foreign imports could fuel inflation and cut corporate profits. Chuck Carlson, CEO of Horizon Investment Services, said: Currently, the market still views tariffs more as a negotiating tool than as a long-term strategy, and if that starts to change, I think it will have a negative impact on the stock market.
