The state of buffer ETFs

Buffer ETFs are designed to limit losses down to a set point and, in exchange, cap how much of an index's gain an investor can capture over a set period, typically a year, before the fund resets. As of Sep 8, 2026, the data covers 243 such funds across three issuers. Of these, 79 funds, or 33% of the total, are sitting at their cap, meaning the index they track has already risen far enough that these funds have no further upside for the remainder of the current period. Another 20 funds, or 8%, have moved into the range where their buffer is actively absorbing losses. The remaining 144 funds, 59% of the total, sit in an open band between these two states.

For the median fund across all 243, the issuers' own figures show room to gain another 5.2% from the current price before hitting its cap, and room to fall 6.0% before the buffer starts cushioning losses. These figures differ by issuer. Innovator, with 107 funds, shows a median remaining gain of 5.8% and a median fall of 5.8% before the buffer engages, with an expense ratio of 0.80%. First Trust, with 81 funds, shows a smaller cushion on the upside at 4.6% but a larger one on the downside at 7.4%, also at 0.80%. AllianzIM, with 55 funds, shows 4.9% on both measures, with a lower expense ratio of 0.70%.

The reset calendar over the next twelve months shows a pattern tied to how much time has elapsed since each fund's period began. Funds resetting soonest have had the most time for their underlying index to climb toward the cap, so they carry the least remaining room to gain. In Sep 2026, 42 funds reset, 23 of which are already at cap, and the median fund in this group has just 0.8% of gain left, following a median index move of +15.0% since the period started. This pattern eases through the months: by Apr 2027, only 1 of 15 funds is at cap, with a median remaining gain of 8.2%. By May through Aug 2027, no funds in these reset months are at cap, and median remaining gain climbs as high as 15.1% in Aug 2027, alongside a median index move of −0.1% since those periods began.
