As of Nov 4, 2026. Source: ETFIQ.

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

They do not reset together. CPSD has 26 days of its period left and UJAN has 57, so the two are not the same bet on the same months.

Where each one stands today

CPSD resets first, on Nov 30, 2026, 26 days from now; UJAN runs to Dec 31, 2026, 57 days. A fall from here reaches CPSD’s buffer after 5.8% and UJAN’s after 12.9%. 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.
