On Monday, U.S. stock futures declined with S&P 500 futures decreasing by 0.8%, jeopardizing a nine-day winning streak, the longest since November 2004. Meanwhile, Nasdaq 100 futures fell by 1%, and Dow Jones futures dropped approximately 270 points. This downturn in market sentiment stemmed from stalled trade negotiations between the U.S. and China. President Donald Trump mentioned there were no plans to converse with Chinese President Xi Jinping this week, though he suggested potential upcoming trade agreements with unspecified nations. Additionally, markets are on edge awaiting the release of the ISM Services PMI later in the day, as well as the Federal Reserve's policy announcement set for Wednesday. On the corporate scene, major tech companies saw their premarket trading numbers decline, including Apple (-1.1%), Microsoft (-0.6%), Nvidia (-1.5%), Amazon (-1.6%), Meta (-1.1%), Alphabet (-0.9%), and Tesla (-0.9%). Furthermore, Berkshire Hathaway's shares fell approximately 2% in premarket trading following Warren Buffett's announcement of his intention to step down at the end of the year, signaling the end of his six-decade leadership of the conglomerate.
