Summary · why it matters
U.S. stock index futures tumbled on Tuesday as a global rout in technology shares intensified, with September S&P 500 E-Mini futures down 1.26% and Nasdaq 100 E-Mini futures down 2.47%. Chip and AI infrastructure stocks led the pre-market declines, as Micron Technology slumped over 8%, Marvell Technology slid more than 7%, and Intel sank over 6%, following a selloff in Korean and Japanese chipmakers that fueled concerns about the sustainability of the AI-driven rally. The pullback also reflected growing unease over sky-high tech valuations and the prospect of a Federal Reserve interest rate hike this year, with rate futures pricing a 32.1% chance of a 25-basis-point increase at the July FOMC meeting. In Europe, the Euro Stoxx 50 Index fell 1.53%, dragged lower by chip and AI-related stocks, while a survey showed Eurozone private-sector activity contracted for a third straight month in June. Asian markets also closed sharply lower, with Japan's Nikkei 225 Stock Index dropping 3.55% and China's Shanghai Composite Index losing 1.37%, as investors locked in profits on richly valued tech names. Investors now await preliminary U.S. purchasing managers' surveys, with economists expecting the June S&P Global Manufacturing PMI to come in at 54.6 and the Services PMI at 51.1, along with earnings reports from FedEx, Cerebras Systems, and Carnival Corporation.
