U.S. stock markets surged to new record highs as the S&P 500 and Dow Jones rallied on the back of strong corporate earnings linked to artificial intelligence and optimistic signals regarding a potential Iran deal. Investors showed renewed confidence as corporate profits continued to rise, and easing oil prices contributed to the upbeat market sentiment. Notable tech companies like Palantir saw significant gains, further boosting the indices. Speculation surrounding the reopening of the Strait of Hormuz has also played a pivotal role in driving market optimism, as Wall Street appears to be shaken off previous concerns over inflation.
