U.S. stock futures pared early advances as geopolitical tensions offset optimism over potential Iran deal progress.
Dow Jones, S&P 500, and Nasdaq futures climbed early Tuesday on hopes for an Iran nuclear deal, driving crude oil prices lower. Gains narrowed after Iran pledged retaliation for U.S. military strikes conducted Monday, injecting uncertainty into markets.
Futures had extended holiday weekend rallies before the geopolitical shift. Marvell Technology (MRVL), Dell Technologies (DELL), and Costco Wholesale (COST) are set to report earnings this week, adding corporate focus to the session.
No immediate market reaction data was provided, but futures remained off earlier highs as investors weighed risks.
