Side by side
As of Nov 4, 2026. Source: ETFIQ.
Both are already at their cap, so neither gains from more rise in the index before the period ends.
They do not reset together. CPSP has 147 days of its period left and AAPR has 513, so the two are not the same bet on the same months.
Where each one stands today
CPSP resets first, on Mar 31, 2027, 147 days from now; AAPR runs to Mar 31, 2028, 513 days. A fall from here reaches AAPR’s buffer after 4.5% and CPSP’s after 4.0%. Both track SPY, so what separates them is where each is in its own period.
AAPR
SPY had already risen past this fund's cap of +15.7% for the period on Nov 4, 2026, so in index terms there is no more upside to collect. The fund's own price can still drift up to about 10.6% as the period runs out. The fund's price can fall 4.5% from here before the buffer starts absorbing losses, by the issuer's number. In index terms, SPY can fall 15.2% 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. 513 days remained on Nov 4, 2026. On Mar 31, 2028 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.
