Side by side
As of Oct 28, 2026. Source: ETFIQ.
They do not reset together. PMAY has 184 days of its period left and PAUG has 276, so the two are not the same bet on the same months.
Both are Innovator funds, so the difference between them is the terms rather than the house.
Where each one stands today
PMAY resets first, on Apr 30, 2027, 184 days from now; PAUG runs to Jul 31, 2027, 276 days. PAUG can still gain 11.0% before its cap, PMAY 7.1%. A fall from here reaches PAUG’s buffer after 2.5% and PMAY’s after 5.3%. Both track SPY, so what separates them is where each is in its own period.

How this is computed
It is a place in a set, not a rating or a recommendation.
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.
