# Quantum Stocks Jump as Growth Trade Revives

Nvidia , Micron (NASDAQ:MU) and a long list of AI and quantum computing stocks rallied Monday after the U.S. and Iran reached a peace agreement, giving investors a reason to jump back into some of the market's highest-growth themes.

The biggest gains came from memory-related names. Micron climbed about 8%, while Western Digital surged 13% and Seagate jumped 9%. In South Korea, memory giants Samsung Electronics gained 4.5% and SK Hynix rose 6.4%. Investors appeared to be betting that lower geopolitical risk could improve sentiment toward a sector already benefiting from booming AI infrastructure demand.

The rally spread well beyond memory. AMD gained roughly 8%, Qualcomm rose 6%, and Nvidia added about 2%. Quantum computing stocks were even hotter, with Arqit Quantum soaring 29%, D-Wave rising 13%, Quantum Computing (QUBT) gaining 12%, and Rigetti adding 10%.

Monday's move was a reminder that when geopolitical fears ease, money often rotates quickly back into risk assets and long-duration growth stories. The next thing to watch is whether details of the Iran agreement hold up and whether the rally has enough momentum to extend beyond the initial relief trade.
