DDTS vs ZSEP: which one stands where?
As of Sep 21, 2026 DDTS can fall 0.7% before its buffer engages and ZSEP 0.3%.
These are two different products. ZSEP is a floor fund, which caps how far a holder can fall. DDTS is a buffer fund, which absorbs the first part of a fall and leaves everything below it with the holder.
Both are Innovator funds, so the difference between them is the terms rather than the house.
Where each one stands today
DDTS resets first, on Aug 31, 2027, 344 days from now; ZSEP runs to Aug 31, 2027, 344 days. DDTS can still gain 13.9% before its cap, ZSEP 8.5%. A fall from here reaches DDTS’s buffer after 0.7% and ZSEP’s after 0.3%. Both track SPY, so what separates them is where each is in its own period.
Every figure is ETFIQ’s own, from the issuer’s published outcome-period terms. A buffer ETF holds FLEX options on its reference index rather than shares, so there is no holdings overlap between two of them to report.
