Iran peace-talk progress steadies US stock futures

US stock index futures trimmed early losses Sunday evening after Iran signaled major progress in peace talks in Switzerland; S&P 500 futures fell about 0.4% to 7,539.25, Nasdaq-100 futures about 0.4% to 30,592, and Dow futures about 0.3% to 51,848, as traders weighed geopolitical tensions against a tech rally and upcoming economic data (PMIs and PCE). Mediation updates from Pakistan and Qatar contrasted with Trump’s threats of strikes, keeping risk sentiment sensitive to U.S.-Iran developments.
