U.S. stocks faced their worst day in over a month as major indexes, including the Dow, Nasdaq, and S&P 500, significantly tumbled. The decline was largely driven by a renewed sell-off in technology stocks, with heavy losses in key players such as Nvidia and other AI-related companies contributing to investor fears. As concerns about interest rates intensified and hopes for a Federal Reserve rate cut dwindled, traders adjusted their expectations in response to the evolving economic landscape. The Dow fell by 800 points, marking a significant shift in market sentiment, while the Nasdaq also experienced a notable drop of 2.3%. Analysts are expressing caution as economic uncertainty looms, impacting the technology sector and leading to considerable volatility in the markets.
