U.S. stocks fell sharply amid a combination of rising oil prices and concerns over weakening semiconductor stocks. The S&P 500 and Nasdaq experienced significant drops, while the Dow managed to hold onto some gains. Investors are closely watching tech earnings reports and the ramifications of ongoing tensions between the U.S. and Iran. Chipmakers like Nvidia and Intel led the declines, contributing to a broader market pullback as worries over AI spending and fluctuating oil prices weighed heavily on investor sentiment. The market is currently navigating through a complex landscape of geopolitical tensions and financial pressures.
