US stocks closed higher on Monday as investors tried to stabilize the market following last week’s losses driven by cracks in AI-related trading and concerns over new tariffs. The S&P 500 rose 0.2%, the Nasdaq 100 advanced 0.4%, and the Dow Jones added 69 points, supported by gains in tech and AI-focused companies such as Nvidia (+2.1%), AMD (+1.2%), and Micron Technology (+4.2%). Video game company Electronic Arts jumped 4.5% after announcing a $55 billion take-private deal, reflecting broader M&A momentum that has topped $1 trillion this year. Market participants are closely watching the risk of a US government shutdown, which could delay key economic releases, including Friday’s nonfarm payroll report, raising uncertainty around the Federal Reserve’s rate-cut decisions. Despite these headwinds, equities remain on track for modest September gains, with the S&P 500 up nearly 3%, the Dow rising 1%, and the tech-heavy Nasdaq outperforming with a 5% rally.
