Stocks plummeted on Wall Street today, closing sharply lower as investors grappled with mounting concerns over credit stress, geopolitical tensions, and the disruptive potential of artificial intelligence. The decline reflected a broad-based sell-off across major indices, with technology and financial stocks bearing the brunt of the selling pressure. The S&P 500 fell approximately 1.2%, while the Nasdaq Composite dropped 1.8%, marking one of the sharpest daily declines in months. Analysts cited rising borrowing costs and uncertainty surrounding global conflicts as primary drivers of the sell-off, amplifying fears that corporate earnings growth could be stunted. The market's sharp retreat underscored the fragile sentiment prevailing despite recent economic data suggesting resilience in the labor market.
