U.S. Investors Flock to Defense Stocks Amid successive outbreaks of geopolitical risks such as the Russia-Ukraine war and tensions between the U.S. and Iran, U.S. institutional investors are accelerating capital injections into the defense industry. According to reports from Britain's Financial Times, data shows that net inflows into U.S.-listed defense ETFs in the first quarter of this year reached $4.8 billion, whereas the figure was only $283 million a year ago, and two years ago even recorded net outflows. Meanwhile, annual committed contributions by U.S. public pension plans to defense-focused private equity funds more than doubled between 2022 and 2025, while overall private equity commitments declined by 2% during the same period. In the first quarter of this year, commitments to defense funds continued to grow at a double-digit pace, while allocations to the broader private equity market remained in contraction. Behind these capital flows lies a redefinition by investors of defense spending from a "cyclical trade" to a "multi-year demand story." ## From Cyclical Trades to Structural Themes Matthew Bartolini, Head of Global Research Strategy at State Street Investment Management, stated plainly: "What has happened over the past year is that we now face a market defined by higher geopolitical risks and less global cooperation. Defense spending has shifted from what was once a cyclical trade to something with more multi-year demand characteristics." The logic is not complex: wars are ongoing, military budgets are rising, and orders are pouring in. European defense expenditure surged by 60% between 2020 and 2025. Earlier this April, the White House proposed a fiscal year 2027 military budget of up to $1.5 trillion, a significant increase from the current $901 billion. External risks further reinforce this narrative. The possibility of direct confrontation between Russia and NATO, along with further escalation in the Middle East—these potential conflicts lead investors to believe that higher military spending may be structural rather than temporary. A report released last December by the Council on Foreign Relations noted: "The world has undeniably become more violent and disorderly. In fact, the number of armed conflicts has now reached its highest level since the end of World War II." ## Simultaneous Surge in Public and Private Markets Market performance validates investors' judgments. Since the full-scale outbreak of the Russia-Ukraine war in 2022, the S&P Aerospace & Defense Select Industry Index has risen cumulatively by 142%, while the S&P 500 gained 64% over the same period—the excess return of the defense sector is quite significant. The private market is equally hot. Anduril Industries, a defense startup known for AI-driven autonomous weapons and surveillance systems, saw its valuation skyrocket from $14 billion to $60 billion over the past two years. Arlington Capital Partners, a defense-focused private equity firm, completed its latest fundraise of $6 billion last October, a 57% increase from the previous round, with more than a dozen public pension plans participating. The assets under management of the Invesco Aero & Defense ETF have grown from $653 million in 2022 to $8.4 billion, with the increase primarily driven by sustained net inflows. Rene Reyna, the fund's manager, stated that inquiries from institutional investors regarding defense ETF strategies have been "very numerous" in recent months. ## ESG Retreat, Defense "Unlocked" Another driver of capital influx is the decline of ESG investment principles. Julian McManus, a fund manager at Janus Henderson Investors, recalled that top defense companies like BAE Systems had long carried labels such as "dull, slow-growing, low-margin," further hampered by ESG pressures. "Three to five years ago, the mainstream view within the ESG community was that all defense stocks were bad and essentially uninvestable from an ESG perspective." Now the tide has turned. The Trump administration's continued crackdown on ESG issues has accelerated the marginalization of this concept in the U.S. market. Paul O'Brien, trustee of the Wyoming Retirement System, bluntly stated: "ESG has been hammered in the U.S. over the past two or three years." Kirk Konert, managing partner at Florida-based defense private equity firm AE Industrial Partners, noted that global instability has risen "sharply" in recent years, making defense and national security spending a "necessity." ## Risks of Overvaluation Emerge Amid the flood of hot money, some investors are sounding warnings. Reyna admitted that defense stocks appear "overvalued on a growth-adjusted basis," which partly explains the recent stock price correction. Konert also cautioned investors against "simply chasing the hottest trades and buying at the highest prices." Additionally, there are voices questioning the contribution of defense investments to the broader economy. O'Brien offered an analogy: "You can contrast this with capital flowing into data centers—data centers generate revenue and output, contributing to the economy. But when you buy nuclear submarines, missiles, or aircraft carriers, they just sit there; you hope never to have to use them." ### Related Stocks - [DFNS.US](https://longbridge.com/en/quote/DFNS.US.md) - [PPA.US](https://longbridge.com/en/quote/PPA.US.md) - [ITA.US](https://longbridge.com/en/quote/ITA.US.md) - [ARKX.US](https://longbridge.com/en/quote/ARKX.US.md) - [DFEN.US](https://longbridge.com/en/quote/DFEN.US.md) - [XAR.US](https://longbridge.com/en/quote/XAR.US.md) - [.SPX.US](https://longbridge.com/en/quote/.SPX.US.md) - [IVZ.US](https://longbridge.com/en/quote/IVZ.US.md) - [JHG.US](https://longbridge.com/en/quote/JHG.US.md) - [BAESY.US](https://longbridge.com/en/quote/BAESY.US.md) - [BA.UK](https://longbridge.com/en/quote/BA.UK.md) ## Related News & Research - [L3Harris Technologies Inc (NYSE:LHX) Short Interest Update](https://longbridge.com/en/news/283208512.md) - [GE Aerospace Earnings: What To Look For From GE](https://longbridge.com/en/news/283287262.md) - [VSBLTY GROUPE TECHNOLOGIES BRINGS AI-POWERED COUNTER DRONE DETECTION TO THE GULF REGION AS TRADITIONAL DEFENSES REACH THEIR LIMITS](https://longbridge.com/en/news/282834188.md) - [How Fresh Analyst Buzz and Geopolitical Jitters At General Dynamics (GD) Has Changed Its Investment Story](https://longbridge.com/en/news/283122121.md) - [Air Canada to cut four NY-bound flights as fuel prices soar due to Iran conflict](https://longbridge.com/en/news/283176971.md)
