What Happened Today

Today, the stock market took a hit with the S&P 500 dropping 1.3%, the NASDAQ declining by 1.5%, and the Dow falling 1.0%. This downturn was largely driven by heightened tensions with Iran following recent military actions that have raised concerns about further conflict in the region.
