U.S. Stock Market Today Adds $1 Trillion as Ceasefire Hopes Boost Markets

U.S. stocks rallied Monday, adding roughly $1 trillion in market value as investors responded to signs of easing tensions between Israel and Iran. The S&P 500 rose 1.02%, adding about $713 billion in market capitalization, while the Nasdaq gained 2.68%, adding approximately $946 billion. The move followed comments from President Donald Trump that Israel and Iran are seeking an immediate ceasefire and that negotiations remain ongoing. Markets viewed the developments as reducing geopolitical risk, helping fuel a rebound in equities after last week’s sharp selloff.
