On Monday, the US stock market experienced an uptick, with the S&P 500 advancing by 0.3%, the Nasdaq increasing by 0.5%, and the Dow Jones climbing approximately 60 points. This rise was largely driven by optimism surrounding AI-related collaborations. Notably, AMD's stock surged by over 30% following an agreement with OpenAI to supply 6 gigawatts of AMD GPUs over several years, a deal that also grants OpenAI a warrant for up to 160 million AMD shares. The leading sectors of the day included utilities, industrials, and technology, while consumer staples and real estate underperformed. Among mega-cap stocks, Microsoft (+0.8%), Alphabet (+0.8%), and Tesla (+3.3%) saw gains, whereas Apple remained relatively unchanged, and Nvidia (-1.4%), Amazon (-0.8%), Meta (-2%), and Broadcom (-2.8%) experienced declines. Concurrently, the government shutdown persisted into its sixth day, following the Senate's fourth unsuccessful attempt to pass spending proposals on Friday. Legislators are scheduled to reconvene on Monday to vote on a Democratic funding plan and a Republican-led stopgap bill, although neither is anticipated to pass.
