Why did most Gulf stock markets rise despite stalled Iran peace talks and disruption in the Strait of Hormuz?

Most Gulf bourses gained because investor sentiment remained resilient amid regional uncertainty, with Saudi Arabia's TASI index rising 0.9%—driven by strong performances from Al Rajhi Bank (+1.5%) and Saudi Aramco (+1%)—and Qatar's index climbing 0.2%, supported by a 1.5% rise in Qatar National Bank; Egypt's EGX30 also advanced 1.1%, buoyed by Telecom Egypt's 3.6% gain following a sharp quarterly profit increase.
