As of Nov 4, 2026. Source: ETFIQ.

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

They do not reset together. JANU has 57 days of its period left and AJAN has 422, so the two are not the same bet on the same months.

Where each one stands today

JANU resets first, on Dec 31, 2026, 57 days from now; AJAN runs to Dec 31, 2027, 422 days. A fall from here reaches AJAN’s buffer after 4.0% and JANU’s after 8.4%. 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.
