9 July 2026 · Source balance: Centre

U.S. stock markets closed higher Thursday as investors reassessed the fallout from renewed Middle East tensions. The Nasdaq Composite gained one point three percent to twenty-six thousand two hundred and seven, while the S and P five hundred rose point eight one percent to seven thousand five hundred and forty-three. The Dow added just point two seven percent. The volatile week began Tuesday when the U.S. Treasury revoked a sanctions waiver on Iranian oil sales and launched strikes on Iranian targets in response to reported attacks on commercial vessels. President Trump declared the U.S. Iran ceasefire over, sending oil prices surging more than four percent Wednesday. However, investors regained confidence Thursday as oil retreated, sliding nearly two percent. Semiconductor stocks led the rebound, with Micron gaining four point five percent. The Nasdaq pared earlier losses while the Dow and S and P five hundred struggled with energy-driven inflation concerns. Markets remain volatile as investors wait for clarity on U.S. Iran tensions and their impact on global energy supplies through the critical Strait of Hormuz.
