U.S. stock markets experienced a notable downturn as the S&P 500 snapped its seven-day winning streak, primarily driven by a decline in tech stocks, particularly Oracle, which raised concerns regarding AI profitability and cloud margins. The Dow Jones also fell, reflecting broader economic worries that have begun to overshadow optimism from recent market rallies. Investors are increasingly cautious as labor market uncertainties persist and inflation fears rise, prompting a reevaluation of market positions. As the shutdown enters its seventh day, the impact on investor sentiment is becoming clear, leading to mixed responses across key indices. Futures remain flat as traders await further cues from upcoming Fed speakers.
