These are two different products. PMSE is a floor fund, which caps how far a holder can fall. PBSE is a buffer fund, which absorbs the first part of a fall and leaves everything below it with the holder.

Both are PGIM funds, so the difference between them is the terms rather than the house.

Where each one stands today

PBSE resets first, on Aug 31, 2027, 300 days from now; PMSE runs to Aug 31, 2027, 300 days. PBSE can still gain 11.1% before its cap, PMSE 7.1%. A fall from here reaches PBSE’s buffer after 1.2% and PMSE’s after 1.1%. 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.
