CPSJFull floor

CPSJ: reference +2.3% since period start, fund +1.0%; buffer −0 to floor; cap +7.6%; Full floor.

PBAUBetween buffer and cap

PBAU: reference +2.1% since period start, fund +1.4%; buffer 0 to −20; cap +12.2%; Between buffer and cap.

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

They do not reset together. CPSJ has 273 days of its period left and PBAU has 304, so the two are not the same bet on the same months.

Where each one stands today

CPSJ resets first, on Jul 1, 2027, 273 days from now; PBAU runs to Jul 31, 2027, 304 days. A fall from here reaches CPSJ’s buffer after 1.1% and PBAU’s after 1.9%. Both track SPY, so what separates them is where each is in its own period.

Every figure is ETFIQ’s own, from the issuer’s published outcome-period terms. A buffer ETF holds FLEX options on its reference index rather than shares, so there is no holdings overlap between two of them to report.
