European defense stocks, which experienced significant gains in 2025 due to increased state military spending in response to geopolitical instability, have entered a period of consolidation in 2026. The Stoxx Europe Aerospace & Defence index is down 1.2% year-to-date, underperforming the broader Stoxx 600 index, which has returned 4.8% over the same period [1]. Analysts attribute this cooling to a shift in investor focus from broad sector bullishness to a more selective scrutiny of individual company performance and fundamentals [1].
Investor sentiment has become more cautious following underwhelming first-quarter earnings reports, with industry leader Rheinmetall missing estimates. This has led to questions about the sector's potential for further upside, especially given Rheinmetall's substantial 400% gain over the past three years and 150% gain in 2025, which many believe already price in several years of sustained growth [1]. According to Matthew Dorset, equity research analyst at Quilter Cheviot, high valuations make it difficult to determine the appropriate multiple for companies like Rheinmetall [1].
Market reaction to geopolitical events has also been muted. While shares of defense companies initially held up after the U.S. and Israel launched attacks on Iran on February 28, concerns about a broader Middle East conflict did not translate into sustained gains. Major defense ETFs, including the WisdomTree Europe Defence ETF, iShares Europe Defence ETF, and VanEck Defense ETF, remain below their pre-war levels [1].
Looking ahead, analysts such as Loredana Muharremi from Morningstar expect some upside in the second half of the year as government orders, down payments, and deliveries materialize, but caution that it will take time for stock prices to recover to previous highs. Muharremi also suggests that companies with diversified product offerings, especially those with strong electronic components, are better positioned than those focused mainly on land-based equipment [1]. Dorset notes that the evolving nature of warfare, as seen in Ukraine, raises questions about future demand for traditional land vehicles and artillery [1].
CONCLUSION
European defense stocks are experiencing a period of consolidation in 2026 after a strong 2025, with investor sentiment turning more cautious amid high valuations and missed earnings. While some upside is expected later in the year as government spending materializes, the sector faces challenges from changing warfare dynamics and selective investor scrutiny. Diversified companies with advanced electronic offerings may be better positioned for future growth.
