Watch These 3 Defense Stocks to Know if EUAD Can Hold Its Gains

The Select STOXX Europe Aerospace & Defense ETF (NYSEARCA:EUAD) has snapped back hard after a sluggish start to the year. Shares sit near $43 after a 8% gain over the past month, pulling EUAD back into positive territory for 2026 at roughly 1% year to date. That recovery follows a 5% April drawdown and a moment of doubt about whether last year’s blistering 55% surge in 2025 had pulled too much future return forward. For investors holding EUAD now, the live question is whether procurement budgets convert into signed contracts fast enough to justify current multiples.

The European budget cycle is the only macro that matters

EUAD is a pure expression of one trade: that Europe spends what it has promised on defense. The EU’s €800 billion ReArm Europe program and Germany’s loosened debt brake set the ceiling. Actual national defense budgets set the floor. The single number to watch over the next 12 months is the share of NATO members hitting and exceeding the 2% of GDP spending threshold, and how many move toward the higher targets being debated for the alliance’s 2026 summit.

The data source to bookmark is NATO’s annual “Defence Expenditure of NATO Countries” report, typically released in June, alongside SIPRI’s military spending database in late April. Check it quarterly. Eurostat’s general government expenditure releases offer mid-cycle confirmation. The transmission mechanism is direct: when the UK’s MoD or Germany’s Bundestag approves a multi-year equipment plan, names like Rheinmetall and BAE Systems book orders that flow through EUAD within one or two rebalance cycles. The 2022 to 2025 cycle showed the lag: announcement to contract award ran roughly 12 to 18 months, and equity prices led contract signings by about six months.

If you want the opposite exposure for a different macro view, the iShares U.S. Aerospace & Defense ETF (NYSEARCA:ITA) leans on the Pentagon budget and lagged EUAD badly last year, returning roughly 17% in 2025. Owning both blurs the trade.

Concentration in three names defines the fund

The fund-specific factor that matters most is the book-to-bill ratio at EUAD’s three largest holdings: Airbus, BAE Systems, and Rheinmetall. Disclosures show over 105% of the fund sits in its top 25 holdings once cash offsets are accounted for, and the top three primes carry the income narrative. BAE Systems is already up roughly 21% so far this year, and Airbus is running a 2.07 million share buyback that closed in mid-January.

Watch each company’s half-year results for order intake versus revenue. A book-to-bill above 1.2x signals the rearmament cycle is still expanding; a reading below 1.0x at any of the three would be the first hard signal that announced budgets are not converting. Investor relations pages publish the data within hours of release. Total return is essentially equity appreciation here, given EUAD’s yield near zero, which makes the concentration risk sharper than it looks on paper.

What to monitor over the next 12 months

The macro signal is the NATO June expenditure report and the alliance’s summit communique on new spending floors. The fund-specific signal is the next set of half-year book-to-bill prints from Rheinmetall, BAE, and Airbus. If both come in strong, EUAD’s 2025 thesis extends into 2027. If budget execution slips or order intake softens at any top holding, the recent rebound stalls.
