As of Nov 4, 2026. Source: ETFIQ.

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

BAUG resets first, on Jul 31, 2027, 269 days from now; ZAUG runs to Jul 31, 2027, 269 days. BAUG can still gain 14.8% before its cap, ZAUG 6.7%. A fall from here reaches BAUG’s buffer after 2.6% and ZAUG’s after 1.5%. 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.
