As of Nov 4, 2026. Source: ETFIQ.

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

Where each one stands today

CPSJ resets first, on Jun 30, 2027, 238 days from now; JULU runs to Jun 30, 2027, 238 days. A fall from here reaches CPSJ’s buffer after 1.7% and JULU’s after 1.9%. 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.
