Two Defense ETFs, One Protocol: XAR vs MISL — Which Optimizes Your Portfolio?
Investors seeking exposure to the aerospace and defense sector face a fork in the protocol: State Street's SPDR S&P Aerospace & Defense ETF (XAR) and First Trust's Indxx Aerospace & Defense ETF (MISL). Both are nodes in the same sector graph, but they execute different weighting algorithms and cost structures. XAR offers a lower-cost, equal-weighted approach, while MISL provides a more concentrated, market-cap-weighted portfolio with a tech tilt. The choice depends on your risk tolerance and conviction in software-defined warfare.
Cost and Size: The Fee Differential
XAR charges an expense ratio of 0.35%, compared to MISL's 0.6%. That is a 71% higher fee for MISL. Both ETFs offer a trailing dividend yield of 0.3%, providing a small income stream. XAR launched in 2011, giving it a longer track record; MISL launched in 2022, making it a newer protocol. For long-term allocators, the fee gap is a significant variable in net returns.
Performance and Risk: Volatility vs. Stability
XAR's equal-weighted structure distributes risk across 47 holdings, with top positions including RTX (3.44%), Axon Enterprise (3.37%), and StandardAero (3.29%). This design amplifies the impact of mid-cap and small-cap players, which can drive higher volatility but also higher returns. MISL, with 49 holdings, is more concentrated in top names: RTX (9.21%), GE Aerospace (8.18%), and Palantir Technologies (8.13%). Its market-cap weighting produces lower volatility, as large caps stabilize the portfolio. Over the trailing 12 months, XAR has outperformed, but MISL has delivered a smoother ride.
What's Inside: Sector Composition
XAR is heavily weighted in industrials (96%), with minor exposure to basic materials (3%) and technology (1%). MISL blends industrials (80%) with a significant technology allocation (13%), including firms like Palantir and Rocket Lab. This tech tilt reflects a conviction that modern warfare is increasingly software-driven. The sector composition is a key differentiator: XAR is pure defense hardware; MISL is a hybrid of hardware and software.
What This Means for Investors
Global defense spending is at generational highs, and both ETFs are positioned to benefit. XAR's equal-weighting is the key to its recent outperformance, distributing risk across a broader range of companies. MISL's tech tilt represents a bet on software-defined warfare, but it comes at a higher cost. For most long-term investors seeking broad, low-cost exposure, XAR's stronger track record and lower fee make it the more practical choice. However, for those who believe the future of defense is algorithmic and data-driven, MISL's concentrated tech exposure may justify the premium.
