Lockheed Martin (LMT) stock jumps while S&P 500 slides – why investors are rushing to defence stocks as US-Iran conflict escalates

Lockheed Martin stock today: Shares of Lockheed Martin Corp moved sharply higher Monday, rising more than 5% in premarket trading as investors rushed into defense names following a dramatic military escalation in the Middle East.

Lockheed Martin (LMT) Stock Surges Today: Middle East Military Escalation Lifts US Defense Stocks But S&P 500 Futures Fall 1.1% as Broader Markets Slide

While broader markets sold off, with futures tracking the S&P 500 down 1.1%, Lockheed Martin stood out as a rare bright spot. The jump came after the US and Israel launched widespread attacks on Iran over the weekend that killed Iranian Supreme Leader Ayatollah Ali Khamenei, ending his 36-year rule. Retaliatory Iranian strikes against US bases in the Middle East killed three US service members, deepening fears of a prolonged conflict.

Why US-Israel Strikes on Iran Shake Global Markets

For investors, the move into Lockheed reflected a familiar pattern. When geopolitical tensions rise, defense contractors often attract buying interest as governments reassess military readiness and potential spending needs. The conflict entered its third day on Monday, with US President Donald Trump warning of further American casualties and saying the fighting could last up to four weeks. That uncertainty has kept markets on edge.


Patrick O’Donnell, Chief Investment Strategist at Omnis Investments, told CNBC that, “It’s very much one of uncertainty at the moment that investors are grappling with,” adding, “Equity markets are a little bit more uncertain about just how long this is going to drag on, for the implication for both growth and inflation that it will have the longer that it goes on. Really, it’s a question of... what’s the duration of this conflict?” as quoted by CNBC.
