<h1>U.S. Markets Plunge; Dow Drops 1,042 Points Amid Tariff Concerns and Tech Stock Declines</h1> The U.S. stock market experienced a significant downturn, with the Dow Jones dropping 1,042 points and the S&P 500 falling by 3.2%, marking one of the worst trading days in years. Concerns over economic policies, particularly tariffs under President Donald Trump, have fueled market volatility, with fears of a potential recession. Major tech stocks, including Nvidia and Tesla, suffered sharp declines. Investors are shifting towards safer assets like U.S. Treasury bonds, pushing yields down. Despite market turmoil, some dealmaking continues, such as Rocket's acquisition of Redfin. Global markets also showed mixed reactions, with declines in Europe and Asia.
