QBSFBetween buffer and cap

QBSF: reference +1.9% since period start, fund +0.7%; buffer 0 to −15; cap +2.9%; Between buffer and cap. Figures to Oct 13, 2026.

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

CPSY is already at its cap, so more rise in the index adds nothing to it before the period ends.

Where each one stands today

CPSY resets first, on Dec 31, 2026, 79 days from now; QBSF runs to Dec 31, 2026, 79 days. A fall from here reaches CPSY’s buffer after 4.7% and QBSF’s after 0.9%. Both track SPY, so what separates them is where each is in its own period.

ETFIQ calculates every figure 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 figure is an ETFIQ calculation with distributions reinvested.
