AAPR vs CPSP: which one stands where?
As of Sep 21, 2026 AAPR can fall 3.6% before its buffer engages and CPSP 3.4%, and CPSP resets 366 days sooner.
They do not reset together. CPSP has 191 days of its period left and AAPR has 557, so the two are not the same bet on the same months.
Where each one stands today
CPSP resets first, on Mar 31, 2027, 191 days from now; AAPR runs to Mar 31, 2028, 557 days. A fall from here reaches AAPR’s buffer after 3.6% and CPSP’s after 3.4%. Both track SPY, so what separates them is where each is in its own period.
Every figure is ETFIQ’s own, from the issuer’s published outcome-period terms. A buffer ETF holds FLEX options on its reference index rather than shares, so there is no holdings overlap between two of them to report.
