As of Nov 4, 2026. Source: ETFIQ.

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

Where each one stands today

APRP resets first, on Mar 31, 2027, 147 days from now; ZAPR runs to Mar 31, 2027, 147 days. APRP can still gain 4.4% before its cap, ZAPR 2.5%. A fall from here reaches APRP’s buffer after 10.5% and ZAPR’s after 4.5%. 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.
