US stock futures edged lower on Thursday as investors continued to monitor developments in the Middle East amid heightened uncertainty over efforts to end the Iran war. The White House maintained that talks are ongoing, with the Trump administration reportedly sending a 15-point proposal to Iran via Pakistan aimed at resolving the conflict. Top Iranian authorities are reviewing the US plan but signaled no intention of entering talks with Washington. Tehran said it would reject a US ceasefire offer, instead countering with a five-point proposal that includes sovereign control over the Strait of Hormuz. In regular trading on Wednesday, the Dow rose 0.66%, the S&P 500 gained 0.54%, and the Nasdaq Composite advanced 0.77%, supported by a pullback in oil prices on hopes for a diplomatic resolution to the conflict. Investors now turn to the latest weekly jobless claims data on Thursday for fresh signals on labor market conditions.
