Side by side
As of Nov 4, 2026. Source: ETFIQ.
These are two different products. CPSO is a floor fund, which caps how far a holder can fall. DDTN 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. CPSO has 330 days of its period left and DDTN has 361, so the two are not the same bet on the same months.
Where each one stands today
CPSO resets first, on Sep 30, 2027, 330 days from now; DDTN runs to Oct 31, 2027, 361 days. A fall from here reaches CPSO’s buffer after 0.6% and DDTN’s after 0.9%. Both track SPY, so what separates them is where each is in its own period.
CPSO
The fund's price can fall 0.6% from here before the buffer starts absorbing losses, by the issuer's number. In index terms, SPY can fall 0.4% 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. 330 days remained on Nov 4, 2026. On Sep 30, 2027 the period ends and a new cap is set.
DDTN
From its price on Nov 4, 2026, the fund can gain about 14.4% 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: 10.0% of the 10.0% 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.
