Rebuilt every trading night.\n Buffer ETFs with the most protection left\n See 15 funds ranked by buffer still below the index level, in index points, current outcome period. Updated Oct 21, 2026. Protection left is not the same as safety. It is how much of the stated buffer has not yet been used. 62 of the 431 buffer ETFs are level at 100.0%, so protection left alone does not order them. Level funds are ordered by days left in the period, most first, then by net assets.\n Buffer ETFs with the most protection left, ranked by buffer still below the index level, in index points, as of Oct 21, 2026. Index return runs from each fund's period start, Sep 30, 2025 to Oct 19, 2026 on this list, to the date of its issuer's latest figure, Oct 21, 2026.
