U.S. stock futures held steady on Tuesday following a robust start to the week for Wall Street, buoyed by a recovery in artificial intelligence-related stocks. On Monday, the Dow Jones Industrial Average increased by 0.15%, the S&P 500 climbed by 0.26%, and the Nasdaq Composite rose by 0.48%, driven by gains in technology and AI-centric companies including Nvidia (+2.1%), AMD (+1.2%), and Micron Technology (+4.2%). The previous week saw equities face challenges due to concerns over the cyclical nature of AI-related investments, coupled with issues such as rising debt and constraints in energy capacity. Nonetheless, investor sentiment remains positive about the sector's profit prospects and the potential for further reinvestment, which could sustain its momentum. In the backdrop, the threat of a federal government shutdown persists as the October 1st funding deadline approaches. As it stands, all three major indices are poised to end September on a higher note, with the Dow up by 1.7%, the S&P 500 increasing by 3.1%, and the Nasdaq advancing by 5.3%.
