On April 15, Jin10 reported that optimism surrounding the resumption of peace talks between the U.S. and Iran has led to a significant rebound in the S&P 500 Index, which is nearing its historical high. According to Jin10, this positive sentiment is expected to boost Asian stock markets at their opening. Steve Sosnick, Chief Strategist at Interactive Brokers, commented, "The key is not whether the peace talks have made substantial progress, but whether we can reasonably expect potential progress. The power of sentiment often outweighs reality." Strategist Michael Ball analyzed that the rise in the S&P 500 is driven by the market's belief that the war with Iran will not cause a widespread economic shock. With the ceasefire agreement holding, Saudi Arabia's east-west pipeline resuming operations, and Iran considering halting shipments through the Strait of Hormuz to advance negotiations, each headline about diplomatic efforts reduces perceived tail risks for traders.
