The state of buffer ETFs

Across the 273 buffer ETFs tracked from 4 issuers, the market snapshot for Sep 10, 2026 shows a familiar three-way split. Of the total, 67 funds, or 25%, sit at their cap, meaning the index they track has already risen far enough that those funds have no further upside for this period. Another 42 funds, or 15%, have moved into the zone where their buffer is absorbing losses, cushioning investors against a decline that has already begun. The remaining 164 funds, or 60%, are open, sitting between those two states. For the median fund across all issuers, the numbers by the issuers' own figures show 5.9% of further gain still available before hitting a cap, and room to fall 4.9% before the buffer starts to work.

The issuer breakdown shows some variation in where funds stand. Innovator, with 107 funds, has 24 at cap and 17 with buffers working, a median remaining gain of 6.3% and a median cushion of 5.3% before losses reach the buffer. First Trust, with 81 funds, has more at cap in absolute terms, 26, and fewer with buffers active, 10; its median fund can still gain 5.0% and can fall 6.9% before the buffer starts. AllianzIM, with 55 funds, has only 5 at cap and 8 with buffers working, a median gain still available of 5.6% and a cushion of 4.1%. Calamos, the smallest group with 30 funds, has 12 at cap and 7 with buffers working; its median fall-before-buffer figure is 3.1%, with no median gain figure listed. Expense ratios across issuers sit at either 0.80% or 0.70%.

Looking ahead by reset month, the pattern connects the amount of remaining cap to how much time is left before a fund resets. Funds resetting soonest, in Sep 2026, show the smallest median remaining gain, 1.4%, alongside the largest median index move since the period started, +13.7%, and the highest count at cap, 20 out of 44 funds. As reset dates move further out, the picture shifts: by Apr 2027, no funds in that month are at cap, and the median remaining gain rises to 8.8%, with the index having moved only +5.5% since that period began. The trend continues into later months; Aug 2027 shows a median remaining gain of 16.5%, alongside a median index move of −1.2%, and zero funds at cap. This reflects the report's underlying point: funds with more time left before reset have had less opportunity for their tracked index to climb toward the ceiling, leaving more headroom on paper.
