Since Operation Midnight Hammer began in June 2025, defense stocks have experienced a significant rally that reflects broader shifts in U.S. geopolitical strategy and military spending. Major contractors like Lockheed Martin climbed 3.6% following the operation, while RTX (Raytheon Technologies) gained 1.8% in the immediate aftermath, adding to its impressive full-year 2025 performance of 27%.
This article examines how the defense sector responded to the operation and what has transpired since, including the current state of these stocks and the forces that continue to shape their performance. The defense stock market reaction to Operation Midnight Hammer illustrates how military events and strategic decisions directly influence investor confidence in aerospace and defense companies. Beyond the initial post-operation gains, the sector has continued to experience record valuations through early 2026, driven by factors including a $961.6 billion defense budget authorization for FY 2026 and substantial order backlogs that extend deep into the 2030s. However, recent weeks have brought renewed volatility as geopolitical conditions have shifted, reminding investors that defense stocks remain sensitive to international events and policy changes.

What Was Operation Midnight Hammer and Its Market Impact?
Operation Midnight Hammer marked a significant U.S. military response in mid-2025, with immediate effects on investor sentiment in the defense sector. The operation triggered measurable positive reactions across major defense contractors, signaling investor confidence that such geopolitical events would sustain demand for military hardware and advanced systems. Lockheed Martin’s 3.6% gain in the immediate aftermath reflected this optimism, as not as a single catalyst but as evidence of an ongoing security environment that would support defense spending. This contrasts with historical patterns where singular military events might trigger larger one-day swings. Instead, the market appeared to absorb the operation as part of a broader, multiyear shift toward elevated defense expenditures and technological modernization initiatives.
Immediate Stock Performance Following the Operation
The immediate post-operation period saw defense contractors climb on expectations of sustained government support and the likelihood of increased demand for their products and services. RTX’s 1.8% gain following Operation Midnight Hammer added momentum to what would become a strong overall year, with the company ultimately delivering a 27% total return for 2025. This performance reflected not just the immediate geopolitical event but the broader narrative that the U.S.
military would require substantial capital investments in the coming years. However, the gains were uneven across the sector, and some contractors saw larger moves than others. L3Harris’s 2.8% jump and Northrop Grumman’s 2.3% climb were healthy responses, but investors also recognized that different contractors serve different mission areas and have different exposure to the specific types of operations that might occur. This divergence in performance foreshadowed the selective nature of defense stock movements throughout 2025 and into 2026, where company-specific factors like order backlogs, contract wins, and management commentary have often mattered as much as broader geopolitical news.
The Broader Defense Sector Rally and Market Context
The context surrounding Operation Midnight Hammer included broader recognition that U.S. military strategy was shifting toward greater readiness and capability investments. By early February 2026, aerospace and defense stocks were hitting all-time highs amid what market analysts have labeled the “Security Supercycle”—a multiyear period in which geopolitical conditions, technological advancement needs, and political will are aligning to support substantial defense spending. This environment has proven more powerful than any single operation in driving sustained investor interest.
The $961.6 billion U.S. Defense Budget authorization for FY 2026 provides concrete evidence of political commitment to this spending trajectory. Beyond annual appropriations, defense contractors are carrying order backlogs that extend into the 2030s, with Lockheed Martin alone holding approximately $194 billion in unfilled orders and General Dynamics experiencing a 30% increase in its backlog. These backlogs represent genuine demand visibility that extends far beyond any single fiscal year, giving investors confidence that the defense sector has a durable growth runway regardless of how specific geopolitical events unfold.
Should Investors Consider Defense Stocks as Part of a Portfolio?
The performance of defense stocks since Operation Midnight Hammer and throughout 2026 has attracted considerable investor attention, but it’s important to understand both the strengths and limitations of this sector for portfolio construction. Defense contractors offer several advantages: they operate under long-term government contracts, have predictable cash flows from sustained spending, and are rarely subject to the competitive disruption that affects commercial industries. The record backlogs and authorized federal spending provide visibility into future revenues that is difficult to find elsewhere in the market. Yet there are meaningful tradeoffs to consider.
Defense stocks can be volatile in response to geopolitical events and policy changes, as demonstrated by Northrop Grumman’s 3.9% decline on March 23, 2026 following signals of de-escalation and pauses in certain military operations. Investors must have a realistic timeline and be prepared to weather periods of weakness when tensions ease or when political currents shift away from military spending. Additionally, regulatory oversight, trade policy, and export controls can all impact profitability in ways that affect defense contractors differently than other industries. A balanced approach would involve recognizing the sector’s strengths while being realistic about its cyclicality and sensitivity to geopolitical shifts.
Volatility and Geopolitical Risk Factors
The defense sector’s recent experience illustrates a fundamental reality: while the long-term trend toward higher defense spending appears robust, near-term volatility remains a consistent feature. Northrop Grumman’s 3.9% decline on March 23, 2026 was directly attributed to Trump administration signals about pausing Iran strikes and broader geopolitical de-escalation. This sharp reversal, occurring just weeks after the company had gained 2.3% in the immediate post-Operation Midnight Hammer period, demonstrates how quickly sentiment can shift when there are credible signs that military action may not occur.
This volatility pattern presents both a warning and an opportunity for investors. The warning is straightforward: defense stocks are not defensive in the traditional sense and should not be held with the expectation of stable, predictable returns regardless of geopolitical conditions. The opportunity lies in recognizing that these swings often create buying or selling opportunities for investors with appropriate risk tolerances and time horizons. Short-term traders and investors close to retirement may find the volatility uncomfortable, while longer-term investors can potentially benefit from the underlying strength of the Security Supercycle while being willing to withstand interim downturns.
The Role of Pentagon Spending and Defense Contracts
The mechanism underlying the defense sector’s strength is straightforward: sustained federal spending on weapons systems, military technology, and infrastructure drives revenue and earnings for companies like Lockheed Martin, RTX, Northrop Grumman, and L3Harris. The $961.6 billion FY 2026 defense budget is not a theoretical number but an appropriation that translates into contracts these companies can count on. Lockheed Martin’s $194 billion unfilled backlog represents work already contracted and funded; the company will deliver these systems over the coming years, generating predictable revenue and earnings.
The record backlogs also signal that the government is not simply authorizing spending in the current fiscal year but is committing to multiyear programs that will sustain these contractors through the decade. This creates a form of visibility that commercial businesses rarely have, making it easier for investors to model future earnings and cash flow. The 30% increase in General Dynamics’ backlog during this period shows the breadth of demand across multiple contractors, suggesting that the benefits of the Security Supercycle are not concentrated in a single company but spread across the sector.
Looking Ahead: What’s Next for Defense Stocks in 2026?
As defense stocks navigate 2026, the fundamental drivers of the Security Supercycle remain in place: geopolitical uncertainty, aging military equipment, technological modernization needs, and political support for defense spending all point toward sustained demand. However, the near-term path will likely remain uneven, with periods of strength interrupted by volatility when tensions ease or when specific military actions are postponed or cancelled. The pause in Iran strikes that triggered the March 23 decline illustrates this reality and suggests that investors should prepare for similar reversals.
The key question for defense stocks going forward is whether the Security Supercycle can maintain momentum despite this volatility. With backlogs extending into the 2030s and a $961.6 billion budget in place, the structural support for defense spending appears durable. However, political conditions, international developments, and shifts in strategic priorities could all alter the trajectory. Investors considering exposure to this sector should do so with a clear understanding that defense stocks offer meaningful long-term growth potential but will require the ability to tolerate near-term swings and the discipline to avoid overweighting a sector that remains dependent on geopolitical conditions.
Conclusion
Defense stocks delivered meaningful gains following Operation Midnight Hammer in June 2025, with Lockheed Martin, RTX, Northrop Grumman, and L3Harris all climbing in the weeks after the operation. These gains reflected investor confidence that the geopolitical environment would sustain elevated defense spending and that government contracts would continue to flow to major contractors. However, the subsequent nine months have demonstrated that while the underlying Security Supercycle remains intact, near-term volatility will continue to shape stock price movements, as exemplified by geopolitical de-escalation triggering a 3.9% decline for Northrop Grumman on March 23, 2026.
Moving forward, the defense sector’s long-term outlook remains supported by record backlogs, substantial federal budget commitments, and multiyear visibility into government spending. However, investors should approach this sector with realistic expectations about volatility and with a clear understanding that geopolitical events will continue to create both opportunities and risks. The Security Supercycle appears durable, but successful investing in defense stocks requires the ability to weather near-term turbulence while maintaining conviction in the sector’s longer-term fundamentals.
