Defense stocks rally as Middle East conflict drives sector re-rating
Lockheed Martin up 30% in 2026 as US defense budget tops $1 trillion and NATO allies boost military spending targets
Lockheed Martin shares have surged nearly 30% in 2026, leading a broader rally in defense stocks as escalating Middle East tensions and a landmark US defense spending reshape investor expectations for the aerospace and defense sector.
The Bethesda-based contractor's stock hit a 52-week high of $692 on March 2 before settling at $627.43 as of March 22, giving the company a market capitalization of $145.2bn. The surge came after "Operation Epic Fury," a joint military campaign targeting strategic Iranian assets on February 28, which triggered the closure of the Strait of Hormuz and sent crude oil prices spiking.
The conflict has fundamentally altered how investors value defense companies. Historically trading at 15 to 18 times forward earnings, defense stocks are now commanding "tech-like" multiples, with Lockheed Martin fetching approximately 31 times earnings. The re-rating reflects what analysts call the end of the "peace dividend" era and the emergence of defense contractors as structural growth beneficiaries in a period of prolonged global instability.
"The market perceives a structural shift in global security, anticipating a multi-year cycle of high-intensity conflict and massive munitions replenishment," according to market analysis following the operation. The sector's rally accelerated after the US defense budget surpassed $1 trillion in 2026, with projections for fiscal year 2027 trending even higher.
The "One Big Beautiful Bill Act" contributed an additional $113bn for immediate military modernization, pushing total 2026 defense spending beyond the historic trillion-dollar threshold. Meanwhile, NATO allies have raised their defense spending targets to 5% of GDP—more than double the previous 2% benchmark—signaling a broader Western commitment to military preparedness.
Lockheed Martin, with its trailing price-to-earnings ratio of 29.16 and forward P/E of 20.88, remains above its 50-day moving average of $625.05. Analysts have set a consensus target price of $663.21, with 21 analysts rating the stock a hold or better. The company's $21.52 in diluted earnings per share and quarterly revenue growth of 9.1% year-over-year provide fundamental support for the valuation expansion.
The broader defense sector has followed Lockheed Martin's lead. RTX Corporation shares jumped 6.5% in early March, while Northrop Grumman gained 6%. The aerospace and defense sub-sectors have significantly outperformed the broader S&P 500 this year, as investors rotate toward companies seen as direct beneficiaries of increased global defense expenditure.
Geopolitical tensions remain elevated, with explosions reported in Tehran as Israel completed a wave of strikes on March 23, underscoring the continued relevance of military assets and missile defense systems. The US Navy is preparing for an expanded, permanent presence in both the Middle East and Indo-Pacific to secure critical shipping lanes, further bolstering the long-term demand outlook for defense contractors.
However, risks remain. Some analysts have raised concerns about valuation levels after the sector's rapid ascent, noting that defense stocks now trade at premiums to historical averages. Additionally, supply chain disruptions, policy shifts, and technological advances favoring AI and autonomous systems could pressure traditional contractors that fail to adapt quickly enough.
The industry is increasingly moving toward "Software-Defined Defense," rewarding contractors that integrate high-margin AI and digital backbones into their hardware platforms. Companies that successfully bridge the gap between traditional military hardware and next-generation technology are likely to maintain their elevated multiples, while laggards may see their valuations compress.
For now, Lockheed Martin's 30% year-to-date gain reflects the convergence of immediate geopolitical catalysts and longer-term structural changes in global defense spending. With the US "Dream Military" budget proposal for 2027 seeking authorization of $1.5 trillion, the sector's rally may have further room to run—provided the geopolitical backdrop remains supportive.
