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. GJUN 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
GJUN resets first, on Jun 17, 2027, 225 days from now; CPSJ runs to Jun 30, 2027, 238 days. A fall from here reaches CPSJ’s buffer after 1.7% and GJUN’s after 3.3%. Both track SPY, so what separates them is where each is in its own period.
CPSJ
The fund's price can fall 1.7% from here before the buffer starts absorbing losses, by the issuer's number. In index terms, SPY can fall 2.7% from today's level to the point where the buffer begins. Protection left, in index points: 100.0% of the 100.0% buffer still sits below today's SPY level. 238 days remained on Nov 4, 2026. On Jun 30, 2027 the period ends and a new cap is set.

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.
