US stock indexes end sharply higher on Thursday, extending earlier gains after President Donald Trump says planned strikes against Iran have been cancelled. According to reports, the three major US market indexes rise strongly, with the day’s moves described as their biggest daily percentage gains since early April, when the US and Iran agreed to a temporary ceasefire. The rally follows heightened market expectations around potential US-Iran military action, with traders reacting to the change in official plans. The reports characterize the increase as broad-based across Wall Street’s main indexes and note that it continues momentum from the prior session. The cancellation announcement is presented as the immediate catalyst for the market jump, with gains building as the news circulates and investors adjust their expectations for risk, energy prices, and regional stability. Overall, both outlets attribute the sharp rise to the decision to cancel strikes and the resulting reduction in near-term geopolitical risk.
