Stock futures edged lower while Treasuries rose Monday morning, the first trading day of March, following massive U.S.-Israel air attacks on Iran.
Here are some of Monday’s biggest stock movers:
Biggest stock gainers
- Lockheed Martin (LMT) +7% – Defense stocks rallied on geopolitical tensions following recent U.S.–Israel strikes on Iran, which have heightened demand expectations for military systems and spending amid fears of broader conflict. Other major defense names such as Northrop Grumman (NOC) +5%, General Dynamics (GD) +4%, RTX (RTX) +6%, and L3Harris Technologies (LHX) +5.6% also advanced, reflecting a broader market rotation into the sector amid rising regional risk.
- EOG Resources (EOG) +6% – Oil stocks rallied on surging crude prices amid escalating Middle East tensions, with Brent crude jumping 9% to around $79 per barrel and WTI climbing 8% to roughly $72 after U.S., Israeli, and Iranian strikes disrupted supply chains near the Strait of Hormuz. Peers also advanced sharply, led by Occidental Petroleum (OXY) and ConocoPhillips (COP) up about 6%, Exxon Mobil (XOM) gained 5%, Chevron (CVX) was up 4%, and Devon Energy (DVN) +6.5%, while oilfield services names Halliburton (HAL) +5% and Schlumberger (SLB) +4%; refiners Valero Energy (VLO) and Marathon Petroleum (MPC) also climbed ~3%.
Biggest stock losers
- Delta Air Lines (DAL) -5% – Airline stocks broadly declined after U.S. and Israeli strikes on Iran disrupted major Middle Eastern airports, including Dubai, grounding flights and triggering one of the sharpest aviation shocks in recent years. Shares of American Airlines (AAL), United Airlines (UAL), and Alaska Air Group (ALK) dropped more than 5%, while Ryanair Holdings (RYAAY) and Joby Aviation (JOBY) fell about 4%, with thousands of flights across the Middle East affected, according to flight-tracking data from FlightAware.
- FedEx (FDX) -3% – Shares fell after announcing it has temporarily suspended pickup and delivery services across several Middle Eastern countries due to recent regional airspace closures. Services in Bahrain, Kuwait, Iraq, Qatar, and the United Arab Emirates have been halted until further notice, and shipments to and from other markets in the region may experience extended transit times.
- Berkshire Hathaway (BRK.B) -2% – Shares slipped after reporting a nearly 30% Y/Y drop in quarterly operating earnings to $10.2B in what marked Warren Buffett’s final quarter as CEO, as insurance operations weighed on results. Insurance underwriting earnings fell more than 54% to $1.6B, and insurance investment income declined about 25% to $3.1B, contributing to a 13% annual drop in insurance operating earnings to $19.8B in 2025, while the BNSF railroad and energy segments delivered comparatively stronger performance.
