As of Nov 4, 2026. Source: ETFIQ.

These are two different products. ZOCT is a floor fund, which caps how far a holder can fall. OCTW 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

OCTW resets first, on Sep 30, 2027, 330 days from now; ZOCT runs to Sep 30, 2027, 330 days. OCTW can still gain 11.3% before its cap, ZOCT 8.5%. A fall from here reaches OCTW’s buffer after 1.4% and ZOCT’s after 0.8%. 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.
