The stock market faced a notable downturn today, with the Dow Jones Industrial Average dropping over 150 points as investors anticipated the upcoming Federal Reserve meeting and grappled with uncertainties surrounding trade deals. The S&P 500 and Nasdaq also experienced declines, effectively ending their longest winning streaks in two decades. Concerns regarding the impact of trade wars and tariffs, exacerbated by statements from the administration, contributed to the negative sentiment. Companies such as Palantir saw significant losses following disappointing earnings reports, further dampening market morale. As Wall Street prepares for key decisions, traders remain cautious amidst the shifting market landscape.
