In a tumultuous day for Wall Street, major tech stocks faced significant declines after disappointing earnings reports from giants Microsoft and Meta. The Nasdaq Composite dropped over 2%, dragging the S&P 500 and Dow down as well. Both companies reported soaring profits linked to their AI initiatives; however, investor concerns over high spending and insufficient infrastructure expansion weighed heavily on their stock prices. As analysts warn of increasing caution among investors regarding the sustainability of AI investments, tech stocks have suffered a sharp sell-off, erasing gains made throughout October. The tech sell-off was further exacerbated by investors bracing for upcoming earnings from Amazon and Apple, signaling a challenging outlook for the tech sector.
