Semiconductor stocks roared back to life on June 11, 2026, after President Donald Trump announced a significant diplomatic breakthrough with Iran, sending chip shares sharply higher.
Advanced Micro Devices (AMD), Micron Technology (MU), Arm Holdings (ARM), and Marvell Technology (MRVL) each climbed 6% or more as investors rushed back into growth-oriented technology names.
Intel (INTC) outpaced many of its peers, with shares rising over 7% after a research firm suggested the company should consider raising capital to support its ongoing turnaround efforts.
President Trump said a formal signing with Iran could come “soon,” adding that he had called off planned military strikes against the country, helping ease months of geopolitical tension.
The diplomatic news sent crude oil prices sharply lower, a development that historically benefits growth and technology sectors by reducing inflationary pressure across the broader economy.
Major indices recovered strongly, with the Nasdaq gaining 2.5%, the S&P 500 rising 1.8%, and the Dow Jones Industrial Average climbing 1.9% as markets closed decisively higher.
Futures markets had already telegraphed the rebound, with Nasdaq futures up 2.07% and S&P 500 futures rising 1.25% ahead of the regular trading session opening.
The broader memory chip and storage sector moved alongside Micron, with Seagate and Western Digital each gaining 5.6%, while SanDisk rose 5.25% during the session.
South Korean chipmakers also benefited from the improved global sentiment, with Samsung gaining 4.5% and SK Hynix climbing 6.42% in overseas trading.
The sharp single-day recovery came after the previous session saw significant selling pressure driven by escalating U.S.-Iran tensions and fresh consumer price index data showing the highest annual inflation rate in three years.
Investors appeared willing to look past the recent inflation data once the geopolitical risk premium tied to Middle East conflict began to fade following Trump’s announcement.
The dual tailwinds of easing tensions and falling oil prices created a favorable backdrop for technology and semiconductor names that had been under pressure in recent weeks.
