Dow Rises as Iran Pause Eases Tensions; Tech Stocks Surge
Markets rallied after Iran signaled a halt to strikes, while Marvell and Corning posted notable moves driven by sector momentum.
U.S. equity markets found firmer footing on Tuesday as geopolitical anxiety receded following reports that Iran had paused its military strikes, giving investors enough breathing room to rotate back into risk assets. The Dow Jones Industrial Average climbed as the news filtered through trading desks, reflecting how sensitive markets have become to Middle East developments that carry implications for oil supply chains and global stability.

Corning's move similarly warrants attention given its exposure to fiber-optic and display technologies that feed into infrastructure spending cycles.
