The first 100 days of a presidential administration are typically scrutinized closely as the public develops a sense of the new government’s agenda and top priorities. The second Trump administration is certainly no exception, and the recent flurry of executive orders and tariff proposals has caused significant uncertainty for policymakers and financial markets alike. Trump’s handling of the Russia-Ukraine War has had an especially notable impact. In March, the Trump administration suspended aid to Ukraine after a tense meeting with Ukrainian President Volodymyr Zelenskyy. That decision elicited a strong response from European leaders, who now have a newfound sense of urgency when it comes to rebuilding the continent’s defense capabilities. In recent weeks, the European Commission, the executive branch of the European Union, announced its “ReArm Europe Plan,” complete with a white paper entitled “European Defense Readiness 2030.” These documents emphasize the need for Europe to bolster defense spending and outline an investment plan to do so.
Global markets took note of this dynamic well before the unveiling of the ReArm Europe Plan, with European defense stocks surging as the continent’s relationship with the Trump administration has deteriorated. To that point, the STOXX Europe Total Market Aerospace & Defense index returned roughly 28.9% in the first quarter, with noteworthy contributors including Rheinmetall, a German arms manufacturer, the French military aircraft manufacturer Dassault Aviation, and Leonardo DRS, an Italian aerospace and defense specialist. This is in striking contrast to the market leaders of 2024, including U.S.-based tech giants such as NVIDIA and Microsoft. The Magnificent Seven basket of stocks have returned roughly -16.0% so far in 2025.
While investors are understandably enthusiastic about the prospects of defense spending jumpstarting the European economy, making these defense goals a reality will not be an easy task, especially for European countries such as France that are heavily indebted with a highly taxed citizenry. One thing is for certain: The market’s response to recent defense initiatives in Europe illustrates the importance of maintaining a diversified investment portfolio, as it is difficult to predict the catalysts that will drive performance reversals like the one detailed above.
