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

JULM resets first, on Jul 16, 2027, 280 days from now; CTAU runs to Jul 31, 2027, 295 days. A fall from here reaches CTAU’s buffer after 2.7% and JULM’s after 2.1%. 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.
