Side by side
As of Nov 4, 2026. Source: ETFIQ.
These are two different products. CPSA is a floor fund, which caps how far a holder can fall. CAUG is a buffer fund, which absorbs the first part of a fall and leaves everything below it with the holder.
Where each one stands today
CPSA resets first, on Jul 30, 2027, 268 days from now; CAUG runs to Jul 31, 2027, 270 days. A fall from here reaches CAUG’s buffer after 0.0% and CPSA’s after 1.3%. Both track SPY, so what separates them is where each is in its own period.
CAUG
Protection left, in index points: 14.6% of the 15.0% buffer still sits below today's SPY level. 270 days remained on Nov 3, 2026. On Jul 31, 2027 the period ends and a new cap is set.
CPSA
The fund's price can fall 1.3% from here before the buffer starts absorbing losses, by the issuer's number. In index terms, SPY can fall 1.2% 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. 268 days remained on Nov 4, 2026. On Jul 30, 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.
