Invesco PPA vs State Street XAR: A Side-by-Side Comparison of Two Aerospace and Defense ETFs for 2026

The Quick Take

• Invesco Aerospace and Defense ETF (PPA) compared to State Street SPDR S&P Aerospace Defense ETF (XAR)
• PPA has higher expense ratio and larger asset base while XAR showed greater resilience in market downturns
• Invesco PPA delivered higher recent returns while XAR demonstrated stronger defensive characteristics
• Defense sector ETF comparison highlights the trade-off between return potential and downside protection

Two competing aerospace and defense exchange-traded funds — Invesco's Aerospace and Defense ETF (PPA) and State Street's SPDR S&P Aerospace and Defense ETF (XAR) — present meaningfully different risk-return profiles for investors seeking defense sector exposure. PPA, the larger of the two by assets under management, carries a higher expense ratio while delivering higher recent returns, suggesting stronger performance in trending markets. XAR demonstrated greater resilience during market downturns, suggesting it is positioned more defensively within the sector — likely due to differences in underlying index methodology and individual security weighting between the two funds driving the performance divergence.

The methodology distinctions between PPA and XAR drive much of the performance divergence. Invesco PPA tracks the SPADE Defense Index, which includes a broader definition of aerospace and defense incorporating companies with significant government contract exposure across manufacturing, services, and technology. State Street XAR tracks the S&P Aerospace and Defense Select Industry Index, which uses equal-weighting across a defined aerospace and defense industry classification, reducing concentration in any single mega-cap defense name. Equal weighting in XAR provides more exposure to mid-cap defense names that often outperform in risk-off environments where capital rotates away from growth stocks toward defense spending beneficiaries and government contractors.

For investors building defense sector allocation in the context of elevated geopolitical risk in 2026 — with US defense budget growth continuing and NATO members increasing military spending — the PPA versus XAR choice depends on investment horizon and return objective. PPA's higher return potential with premium expense ratio suits investors with a medium-term bullish view on defense sector earnings growth. XAR's defensive resilience and equal-weight diversification suits investors who want defense exposure as a portfolio hedge against geopolitical escalation rather than a pure growth bet. Both ETFs provide access to the same fundamental sector tailwind — increasing global defense budgets — but through different construction methodologies that align with different portfolio roles and risk tolerances.
