Today, major U.S. stock indexes, including the Dow, S&P 500, and Nasdaq, experienced significant declines as rising Treasury yields surpassed 4%, coupled with increasing oil prices. The Dow dropped nearly 400 points, reflecting investor anxiety over geopolitical tensions in the Middle East and concerns regarding upcoming economic data and corporate earnings. Analysts noted that the market's slump is also influenced by wavering expectations for Federal Reserve rate cuts. Despite some sectors showing resilience, the overall market sentiment remains cautious as investors navigate these challenges.
