As of Nov 4, 2026. Source: ETFIQ.

UDEC is already at its cap, so more rise in the index adds nothing to it before the period ends.

Where each one stands today

SIXD resets first, on Nov 30, 2026, 26 days from now; UDEC runs to Nov 30, 2026, 26 days. SIXD can still gain 5.9% before its cap, UDEC 1.4%. A fall from here reaches SIXD’s buffer after 2.1% and UDEC’s after 14.1%. Both track SPY, so what separates them is where each is in its own period.

How this is computed

It is a place in a set, not a rating or a recommendation.

ETFIQ calculates every number from each issuer’s published outcome-period terms. Buffer ETFs hold options on an index, not shares, so there is no holdings overlap to report.

Every number is an ETFIQ calculation with distributions reinvested.
