As of Nov 4, 2026. Source: ETFIQ.
These are two different products. CPSN is a floor fund, which caps how far a holder can fall. DDFN 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
CPSN resets first, on Oct 29, 2027, 359 days from now; DDFN runs to Oct 31, 2027, 361 days. A fall from here reaches CPSN’s buffer after 0.3% and DDFN’s after 0.9%. Both track SPY, so what separates them is where each is in its own period.
CPSN
The fund's price can fall 0.3% from here before the buffer starts absorbing losses, by the issuer's number. In index terms, SPY can fall 1.9% 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. 359 days remained on Nov 4, 2026. On Oct 29, 2027 the period ends and a new cap is set.
DDFN
From its price on Nov 4, 2026, the fund can gain about 10.1% more before it reaches its cap. The fund's price can fall 0.9% from here before the buffer starts absorbing losses, by the issuer's number. In index terms, SPY can fall 1.4% from today's level to the point where the buffer begins. Protection left, in index points: 15.0% of the 15.0% buffer still sits below today's SPY level. 361 days remained on Nov 4, 2026. On Oct 31, 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.
