MISL's equal-weight structure trails primes like RTX and Lockheed despite a 50% budget expansion to $1.5T by 2027. Whether suppliers catch up depends on Pentagon program funding.
The First Trust Indxx Aerospace & Defense ETF (MISL) has drawn attention as the U.S. defense budget is projected to reach $1.5 trillion by 2027, a 50% increase from current levels. The fund holds 111 stocks across the sector, with top positions in RTX, Boeing, and Lockheed Martin. Year-to-date, MISL has returned roughly 12%, tracking the broader defense rally. The equal-weight methodology, however, means it does not concentrate in the biggest prime contractors the way market-cap-weighted peers do. That structure has been a drag: the largest holdings carry the same weight as smaller suppliers, so when RTX or Lockheed outperform, MISL captures less of the upside.
A reader who owns the fund directly flagged the issue in a recent note. The equal-weight approach, they argued, makes sense when smaller names lead the cycle but underperforms when primes dominate. Right now, primes are dominating. RTX is up 22% this year. Lockheed is up 18%. MISL's return trails both.
For traders watching the defense space, the question is whether the budget expansion narrative will broaden out to suppliers. If Congress funds programs like the Next-Generation Air Dominance fighter or the Columbia-class submarine at scale, mid-cap suppliers like Huntington Ingalls and L3Harris could catch up. If the money stays concentrated in the primes, MISL will keep lagging its cap-weighted peers.
Two stocks in the fund's orbit have their own dynamics. Rocket Lab (RKLB) carries an Alpha Score of 38, labeled Mixed, reflecting its position as a small launcher with growing government contracts but still-negative free cash flow. Firefly Aerospace (FLY) scores 21, labeled Weak, with a narrower revenue base and higher execution risk. Neither is a top-10 MISL holding, both are names retail traders track as proxies for the new-space defense push.
The budget path is not locked in. The $1.5 trillion figure assumes sustained bipartisan support for defense spending through the next administration. A reconciliation fight or a shift in Pentagon priorities could slow the ramp. MISL's broad exposure means it will move with the sector. The equal-weight structure means it will not lead it.
The Pentagon's fiscal 2027 budget request is due in February. Before that, the trade is about positioning for the budget debate, not the budget itself.
