Why fund managers are loading up on defense stocks

Fund managers are exhibiting increased bullishness on defense stocks, propelled by heightened geopolitical tensions in regions like the Middle East and Indian subcontinent, coupled with NATO allies' recent commitment to raise defense spending to 5% of GDP by 2035 and the ongoing influence of U.S. President Trump's transactional defense policy. This has translated into significant market performance, with the MSCI Europe Aerospace and Defense Index surging 70% and the iShares US Aerospace & Defense ETF gaining over 25% year-to-date, both reaching record highs and attracting substantial investor inflows. While the sector's appeal initially rose post-Russia-Ukraine, current global instability is driving a new wave of buying, though some analysts caution that valuations are elevated and profitability margins have been mixed.

Analysis

A powerful confluence of geopolitical tensions and structural policy shifts is fueling a sustained, bullish trend in the global defense sector. This is evidenced by significant market outperformance, with the MSCI Europe Aerospace and Defense Index surging approximately 70% year-to-date and the iShares US Aerospace & Defense ETF (ITA) gaining over 25% to reach all-time highs. The primary drivers include NATO's landmark commitment to increase defense spending to 5% of GDP by 2035—a long-term demand catalyst—and a growing push for 'strategic autonomy' among European allies, spurred by perceptions of a less certain U.S. security guarantee. Near-term catalysts, such as conflicts in the Middle East and rising tensions in the Indo-Pacific, are sustaining investor interest and driving substantial capital flows, reflected in the nearly doubled allocations by asset managers since 2022 and $1.3 billion in 2024 inflows for one Europe-focused defense ETF. However, despite the strong thematic tailwinds, a key consideration for investors is valuation, as analysts note that share prices are no longer low and some companies face mixed or moderating profit margins.

Key Decisions for Investors

• Given that NATO's 5% spending target and Europe's pursuit of 'strategic autonomy' represent a multi-year structural tailwind, investors should evaluate maintaining or initiating long-term thematic exposure to the defense sector, with a particular focus on European contractors poised to benefit from increased domestic investment.
• As the sector's strong rally has led to elevated valuations, it is prudent to exercise caution on entry points and prioritize fundamental analysis, focusing on companies demonstrating resilient profit margins rather than chasing broad ETF momentum.
• Investors should monitor geopolitical developments in the Indo-Pacific, as analysts highlight this region as a potential future flashpoint that could trigger the next wave of defense spending and expand investment opportunities beyond the current U.S. and European focus.
