US stock futures surged Monday as investors cheered a halt to hostilities between the US and Iran, a development that pulled oil prices lower and reignited a tech-led rally. The S&P 500, Nasdaq, and Dow futures all moved higher, with Nasdaq futures leading the charge as dip buyers returned to technology shares.

The breakthrough came after both nations called a halt to attacks, marking the most significant de-escalation in the region in weeks. The truce drove a muted session in oil markets, which had been pricing in a risk premium from potential supply disruptions. Investors now turn attention to whether peace talks will resume in earnest.

Bloomberg reported Nasdaq futures outperforming as the underlying rally in tech stocks took hold. Reuters noted that while futures climbed, the fragile nature of the truce kept oil markets "on edge." CNBC's live coverage highlighted that gains were broad-based, with the Dow also joining the advance alongside positive news from SpaceX, which rallied on its addition to the Nasdaq-100 index, according to Investor's Business Daily.

Easing geopolitical risk could clear a path for the Federal Reserve to maintain its current policy stance, though some analysts caution that any renewed skirmish would quickly reverse the sentiment. Meanwhile, the dip-buying in tech suggests institutional investors see recent pullbacks as buying opportunities.

Some market participants remain skeptical. CNBC noted the truce is "fragile," and a sudden breakdown in talks could reignite volatility. The coming days will test whether this rally has legs or is merely a relief bounce.
