US stock market loses $4 trillion amid tariff fears

U.S. stock markets have experienced a significant sell-off, losing over $4 trillion in value from the S&P 500's peak last month, primarily due to President Donald Trump's controversial tariffs and the resulting economic uncertainty. The S&P 500 fell 2.7% and the Nasdaq Composite dropped 4% on a single day, marking their largest declines this year. Investors are increasingly concerned about the potential for a recession as tariffs on key trading partners like Canada, Mexico, and China continue to create volatility. Analysts indicate a major shift in market sentiment, with many strategies that previously worked no longer effective. The administration appears to be accepting of market declines, prioritizing broader economic goals over immediate market stability. Upcoming reports on inflation and government funding are closely watched as investors seek clarity in this turbulent environment.
