As of Nov 4, 2026. Source: ETFIQ.

These are two different products. XDEC is a floor fund, which caps how far a holder can fall. GDEC is a buffer fund, which absorbs the first part of a fall and leaves everything below it with the holder.

Both are already at their cap, so neither gains from more rise in the index before the period ends.

Both are First Trust funds, so the difference between them is the terms rather than the house.

Where each one stands today

GDEC resets first, on Dec 18, 2026, 44 days from now; XDEC runs to Dec 18, 2026, 44 days. GDEC can still gain 1.8% before its cap, XDEC 0.9%. A fall from here reaches GDEC’s buffer after 9.2% and XDEC’s after 8.4%. Both track SPY, so what separates them is where each is in its own period.

How this is computed

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.
