Side by side
As of Nov 4, 2026. Source: ETFIQ.
These are two different products. CPSD is a floor fund, which caps how far a holder can fall. DDTJ is a buffer fund, which absorbs the first part of a fall and leaves everything below it with the holder.
CPSD is already at its cap, so more rise in the index adds nothing to it before the period ends.
They do not reset together. CPSD has 26 days of its period left and DDTJ has 57, so the two are not the same bet on the same months.
Where each one stands today
CPSD resets first, on Nov 30, 2026, 26 days from now; DDTJ runs to Dec 31, 2026, 57 days. A fall from here reaches CPSD’s buffer after 5.8% and DDTJ’s after 9.3%. Both track SPY, so what separates them is where each is in its own period.
CPSD
SPY had already risen past this fund's cap of +6.7% for the period on Nov 4, 2026, so in index terms there is no more upside to collect. The fund's price can fall 5.8% from here before the buffer starts absorbing losses, by the issuer's number. In index terms, SPY can fall 11.3% 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. 26 days remained on Nov 4, 2026. On Nov 30, 2026 the period ends and a new cap is set.
DDTJ
From its price on Nov 4, 2026, the fund can gain about 2.4% more before it reaches its cap. The fund's price can fall 9.3% from here before the buffer starts absorbing losses, by the issuer's number. In index terms, SPY can fall 11.0% 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. 57 days remained on Nov 4, 2026. On Dec 31, 2026 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.
