U.S. stock futures saw a slight increase on Tuesday morning, following a sharp decline on Wall Street the previous day. This decline was driven by weakened sentiment towards AI investments ahead of Nvidia’s earnings announcement scheduled for Wednesday. The upcoming report is anticipated to yield insights into the highly scrutinized AI sector, with many predicting that Nvidia will likely surpass expectations yet again. Concerns intensified after it was revealed that Peter Thiel divested nearly USD 100 million worth of his Nvidia shares. Investors are also focused on the forthcoming earnings reports from Target and Walmart, alongside a series of delayed U.S. economic indicators, including the September jobs data, prior to the Federal Reserve’s upcoming meeting. Fed Vice Chair, Philip Jefferson, highlighted potential risks to the labor market and emphasized the importance of a cautious policy strategy. In corporate developments, Berkshire Hathaway increased its investment in Alphabet by purchasing 17.9 million shares during the third quarter, while reducing its stakes in Bank of America and Apple. Additionally, Ford has partnered with Amazon to offer certified used vehicles on the retail giant's platform, making it the second leading automaker to do so.
