US stocks opened the week sharply lower as investors braced for a busy slate of delayed economic releases and a key round of tech earnings, with the Dow plunging 1.1% while the S&P 500 and Nasdaq slid 0.8% and 0.7% respectively. The selloff was led by renewed weakness in big tech with Nvidia down 1.9% ahead of quarterly results due after the close on Wednesday a pivotal test of whether AI related valuations are sustainable and the move was amplified by broad selling across other large caps. At the same time risk pricing has shifted materially as Fed funds futures now imply roughly a 40-45% chance of a 25bp cut in December which is pushing traders to seek clarity from this week’s jobs and other delayed data releases. Alphabet (+3%) bucked the trend after Berkshire Hathaway disclosed a multibillion dollar stake in the company which underpinned its gains and highlighted selective bargain hunting amid the broader selloff.
