What Happened Today

On February 4, 2026, the stock market experienced declines, with the S&P 500 falling by 0.8%, the NASDAQ down 1.5%, and the Dow dropping 0.3%. This downturn was largely driven by escalating geopolitical tensions following a US attack on Iran's Kharg Island, which prompted threats of retaliation from Iran and further escalated fears of conflict in the region.

Additionally, reports of a strike on a factory in Isfahan, Iran, which resulted in multiple casualties, added to the overall sense of unease. Speculation around former President Trump's rejection of ceasefire talks only heightened concerns, causing investors to be cautious in a volatile market.
