Nasdaq Rallies as Chip Stocks Surge Despite Iran Tensions

The Nasdaq composite closed sharply higher in a session defined by a striking divergence: while geopolitical anxiety over Iran cast a shadow across broader risk sentiment, a powerful surge in semiconductor stocks proved strong enough to carry the technology-heavy index decisively into positive territory. It was a reminder that in today's market, sector-specific momentum can overwhelm macro-level fear.

Chipmakers, which have become a bellwether for both artificial intelligence enthusiasm and global supply-chain health, led the advance.

For investors, that concentration is both a source of outsized gains and a latent vulnerability should sentiment in the chip sector reverse.
