In a turbulent trading session, Wall Street closed down amid substantial losses in technology stocks, raising concerns about upcoming earnings reports, particularly from Tesla. The Dow Jones Industrial Average plummeted over 600 points, representing its worst performance in more than a month, while the S&P 500 suffered its largest drop in two weeks. Analysts indicated that rising Treasury yields and disappointing earnings from major players like Boeing and Nvidia exacerbated negative sentiment, leading to a widespread sell-off. Investors remain cautious as they navigate the implications of increasing interest rates and mixed corporate earnings ahead.
