US stock futures were little changed on Tuesday as markets awaited developments from trade talks between the US and China taking place in London. Treasury Secretary Scott Bessent and senior officials met with their Chinese counterparts on Monday to discuss rare earth shipments and the potential easing of export restrictions, with further negotiations expected early Tuesday. On Monday, the S&P 500 and Nasdaq Composite posted modest gains of 0.09% and 0.31%, respectively, while the Dow closed flat, reflecting a cautious start to the week. In corporate news, Apple fell 1.2% amid a lack of major AI announcements at its WWDC event, while Qualcomm jumped 4.1% on its $2.4 billion acquisition of Alphawave. Looking ahead, investors are focused on small business sentiment data due Tuesday, along with key inflation reports later in the week. Earnings results from GameStop and J.M. Smucker Co. are also on the docket.
