DOCTAt its cap

DOCT: reference +17.2% since period start, fund +10.9%; buffer −5 to −30; cap +11.7%; At its cap. Figures to Oct 9, 2026.

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

DOCT resets first, on Oct 16, 2026, 7 days from now; CPSN runs to Oct 30, 2026, 21 days. A fall from here reaches CPSN’s buffer after 6.1% and DOCT’s after 15.1%. 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.
