RTX has emerged as the clear frontrunner among major aerospace and defense stocks in 2026, outpacing both peers and the broader sector benchmark by a meaningful margin.
RTX stock is up 14% year to date, trading at $208.84, leading the trio as the calendar moves through the year’s later months.
GE Aerospace has kept pace reasonably well, with shares up 11% year to date to $341.19, sitting just behind RTX but comfortably ahead of the sector fund.
Boeing is the outlier of the group, with shares down 3% year to date to $210.26, sitting in negative territory while its two peers each record double-digit gains.
The iShares U.S. Aerospace and Defense ETF (NYSEARCA: ITA) lands squarely in the middle of the pack, with shares up 8% year to date to $233.09.
That positioning places the ITA ETF behind both RTX and GE Aerospace while remaining ahead of only Boeing, an unusual outcome given that passive baskets typically smooth out single-name divergence.
Two of the three major names beat their own sector benchmark outright this year, which is not the result most passive holders of a diversified aerospace and defense fund would have expected.
The gap between Boeing and its two peers is a significant driver of the divergence between the individual leaders and the broader basket’s return.
These three companies share a sector label but operate under fundamentally different business models that have been rewarded very differently by the market in 2026.
GE Aerospace builds engines and collects decades of servicing revenue on each one, a recurring-revenue model tied directly to how much of the existing global fleet actually flies each day.
Boeing builds airframes, making it a manufacturing business with considerably more exposure to production execution, program timing, and delivery schedules than either of its peers.
RTX spans defense systems and aerospace components across a wider portfolio than either competitor, giving it multiple growth engines rather than reliance on a single product category.
The spread between the best and worst performer in this group has been wide enough that position sizing carried real consequences for investors who treated all three as interchangeable.
A concentrated bet on any single name produced very different outcomes depending on which company received the heavier weighting, even among three large, established blue chips.
The ITA ETF’s 8% year-to-date result reflects a much broader mix of aerospace and defense holdings than these three names alone, which explains why its return falls between the individual leaders and the lone laggard.
Investors tracking this group into year-end can watch for Boeing’s turnaround story to begin closing the performance gap on GE Aerospace and RTX, or for the current ranking to hold firm.
The 2026 divergence between these three household aerospace and defense names is a reminder that a sector label can conceal more than it reveals about how individual companies actually earn their revenue.
