Side by side
As of Nov 4, 2026. Source: ETFIQ.
These are two different products. CPSM is a floor fund, which caps how far a holder can fall. SIXZ 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
CPSM resets first, on Apr 30, 2027, 177 days from now; SIXZ runs to Apr 30, 2027, 177 days. A fall from here reaches CPSM’s buffer after 2.6% and SIXZ’s after 1.2%. Both track SPY, so what separates them is where each is in its own period.
CPSM
The fund's price can fall 2.6% from here before the buffer starts absorbing losses, by the issuer's number. In index terms, SPY can fall 6.0% 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. 177 days remained on Nov 4, 2026. On Apr 30, 2027 the period ends and a new cap is set.
SIXZ
From its price on Nov 4, 2026, the fund can gain about 7.0% more before it reaches its cap. The fund's price can fall 1.2% from here before the buffer starts absorbing losses, by the issuer's number. In index terms, SPY can fall 1.4% 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.

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.
