As of Nov 4, 2026. Source: ETFIQ.

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

Where each one stands today

DSEP resets first, on Sep 17, 2027, 317 days from now; DDFO runs to Sep 30, 2027, 330 days. DDFO can still gain 9.9% before its cap, DSEP 12.9%. A fall from here reaches DDFO’s buffer after 0.7% and DSEP’s after 6.5%. Both track SPY, so what separates them is where each is in its own period.

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.
