Both are already at their cap, so neither gains from more rise in the index before the period ends.
Where each one stands today
CPSP resets first, on Mar 31, 2027, 147 days from now; TAPR runs to Mar 31, 2027, 147 days. A fall from here reaches CPSP’s buffer after 4.0% and TAPR’s after 11.5%. Both track SPY, so what separates them is where each is in its own period.
CPSP
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 4.0% from here before the buffer starts absorbing losses, by the issuer's number. In index terms, SPY can fall 14.5% 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. 147 days remained on Nov 4, 2026. On Mar 31, 2027 the period ends and a new cap is set.
TAPR
SPY had already risen past this fund's cap of +15.3% for the period on Nov 4, 2026, so in index terms there is no more upside to collect.

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.
