Looking for an Aerospace and Defense ETF? Compare Funds From Invesco and First Trust

Invesco Aerospace & Defense ETF (PPA) is favored over First Trust Indxx Aerospace & Defense ETF (MISL) on trailing performance and risk: PPA returned 25.2% over the past year vs. MISL’s 22.9%, and posted a smaller 3-year max drawdown (-15.2% vs. -17.9%). PPA also has slightly lower fees (0.58% vs. 0.60%) and a higher trailing dividend yield (0.40% vs. 0.30%), with stronger 3-year growth of $2,126 vs. $2,001 from $1,000 invested. Portfolio-wise, PPA holds 60 stocks (vs. 50 for MISL) with less top-10 concentration (55% vs. 62%) and modest foreign exposure (~4% Israel), supporting a more diversified construction.

Analysis

This is mostly a flows-and-structure story, not a fundamental re-rating of defense demand. The market tends to reward the ETF with deeper liquidity when investors want quick sector exposure, so capital should keep migrating toward the larger, more seasoned wrapper unless the high-beta space/software names materially outperform. That makes the implied winner basket the traditional primes and aerospace cyclicals, while the newer, tech-heavier vehicle is effectively a levered bet on continued multiple expansion in names like PLTR and RKLB.

Second-order, the bigger vehicle likely captures the more stable institutional bid: model portfolios, consultants, and factor allocators tend to prefer lower tracking noise and lower concentration when a theme is already crowded. That creates a subtle feedback loop where BA/GE/RTX get incremental passive support even if their underlying fundamentals do not accelerate, while the more concentrated product needs a stronger catalyst set to justify ownership beyond retail momentum.

The contrarian risk is that defense is being treated as a pure defensive-duration trade, but a meaningful slice of the basket behaves like long-duration growth. If real rates back up or budget headlines fade, the tech-heavy exposure should underperform first; if space and software-defense spend keeps compounding, the gap can narrow quickly. Falsifiers: a sustained rally in PLTR/RKLB relative to RTX/GE, or a regime shift in government spending that favors next-gen defense over legacy primes.

Key Decisions for Investors

• Relative-value trade: long PPA / short MISL for 1-3 months, targeting a 3-6% spread if institutional flows continue to prefer liquidity and lower concentration; stop if MISL outperforms PPA by >4% over 4-6 weeks.
• Overweight RTX and GE versus BA within the aerospace-defense sleeve; use any sector strength to rotate toward names with lower execution risk and more durable aftermarket/cash-flow characteristics.
• If you want higher-beta defense-tech exposure, own PLTR or RKLB directly rather than via MISL; the ETF structure dilutes upside with non-linear concentration risk.
• Watch real yields and defense-budget headlines over the next 1-2 months: rising yields or a de-risking macro tape should pressure MISL first; a software/space contract cycle would be the main catalyst to close the performance gap.
