The State Street SPDR S&P Aerospace & Defense ETF (XAR +0.73%) offers a lower-cost, equal-weighted approach to the sector, while the First Trust Indxx Aerospace & Defense ETF (MISL +0.19%) provides a more concentrated, lower-volatility portfolio.
Investors seeking defense exposure often choose between market-cap-weighted strategies and more diversified alternatives. While both funds target the aerospace and defense industry, they differ significantly in their cost structures, weighting methodologies, and historical volatility profiles, which could influence their suitability for different portfolio roles.

What this means for investors
Global defense spending is at generational highs, and both XAR and MISL are positioned to benefit. But they define the aerospace and defense sector in very different ways and have delivered very different outcomes as a result.
XAR’s equal-weighted structure is the key to understanding its recent outperformance. Rather than letting the largest companies dominate, it gives smaller defense contractors the same portfolio influence as industry giants, distributing risk across a broader range of companies.
MISL blends traditional defense industrials with technology companies like Palantir and Rocket Lab. That tech tilt represents a conviction that modern warfare is increasingly fought with software and data rather than hardware alone. It has produced a smoother ride than XAR, albeit with lower recent returns.
Paying nearly seven times more in annual fees for MISL requires you to believe that its tech-infused approach and lower volatility are worth the substantial cost difference. For most long-term investors who want broad, low-cost aerospace and defense exposure, XAR’s stronger track record and dramatically lower fee make it the more practical choice.
