Stock market today: Live updates

S&P 500 futures moved lower Monday night as traders watched rising geopolitical tensions amid the conflict between the U.S. and Iran.

S&P 500 futures slipped 0.2%, while Nasdaq 100 futures were off 0.3%. Futures tied to the Dow Jones Industrial Average lost 85 points, or nearly 0.2%.

The S&P 500 and Nasdaq Composite closed the previous session in the green, marking a sharp reversal from their lows earlier in the session. The broad-market index closed just above the flatline, while the tech-heavy Nasdaq gained nearly 0.4%. The 30-stock Dow lost 73 points, or 0.15% — far off of its lows of the day when the index dropped nearly 600 points.

Investors bought the dip in stocks, which were initially lower to start the new trading week on fears that the widening conflict between U.S. and Iranian forces would weigh on markets. Several defense and energy companies rallied on Monday. Northrop Grumman and Palantir were among the S&P 500’s best performers, up 6% and 5.8%, respectively. A roughly 3% jump in Nvidia helped lift the broader market.

“Historically, what in the near term seems like a geopolitical crisis tends to be largely resolved from a market perspective over the ensuing six months, and where it’s not, it’s often because of an economic downturn that the geopolitical crisis didn’t cause,” Carson Group chief market strategist Ryan Detrick said in a note. “We believe the market has already been pricing in the possibility of a conflict for a month, which may limit the size of a further move and may cause a quicker rebound when the market sees a likely path to resolution.”

Global crude oil prices surged Monday on worries that the U.S.-Iran conflict could disrupt oil infrastructure and push up fuel prices, adding inflationary risks. An Iranian Revolutionary Guard commander said the Strait of Hormuz—the world’s most vital transit route for crude oil—is closed and that Iran would set ablaze ships attempting the route, Reuters reported, citing Iranian media.

Monday was the third day of the U.S. war against Iran after joint U.S.-Israeli military strikes killed Supreme Leader Ayatollah Ali Khamenei over the weekend. U.S. military leaders said more forces are headed to the region and President Donald Trump said the war is projected to last four to five weeks, but that it could go on “far longer than that.”

Heading into Tuesday, investors are awaiting key earnings from cybersecurity company CrowdStrike and retailer Target. Quarterly reports from chipmaker Broadcom and membership warehouse giant Costco are due later this week.
