US stock futures mixed as Trump visits China with tech leaders; Nvidia, Nextpower, and Red Cat in focus

US stock futures showed mixed results with Dow Jones futures falling while S&P 500 and Nasdaq 100 futures rose, following President Trump's visit to China accompanied by major tech CEOs including Nvidia's Jensen Huang and Apple's Tim Cook. Key stocks in focus include Nextpower, which surged after strong earnings and acquisition news, MaxCyte with a significant share jump post-earnings, and Red Cat Holdings which dropped after a public offering. Market sentiment is influenced by steady Treasury yields, expectations of unchanged Fed rates in June, and optimism about AI-driven growth despite geopolitical uncertainties. Investors are also watching upcoming economic data such as the producer price index and Fed speeches for further market direction.
