The technology sector is experiencing a significant downturn in pre-market trading, driven by a wave of disappointing earnings reports from industry giants. Alphabet (GOOGL), Amazon (AMZN), and Intel (INTC) all reported figures that fell short of analyst expectations, sparking concerns about the profitability of heavy investments in artificial intelligence. Alphabet's stock plunged over 12% following its report, contributing heavily to the negative sentiment. The sell-off appears concentrated in the tech sector, with Nasdaq 100 futures down sharply.
