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

FEBM resets first, on Feb 19, 2027, 129 days from now; CPSR runs to Feb 26, 2027, 136 days. A fall from here reaches CPSR’s buffer after 3.5% and FEBM’s after 4.6%. Both track SPY, so what separates them is where each is in its own period.

How this is computed

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.
