Side by side
As of Nov 4, 2026. Source: ETFIQ.
These are two different products. ZMAY is a floor fund, which caps how far a holder can fall. CMAY 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
ZMAY resets first, on Apr 30, 2027, 177 days from now; CMAY runs to Apr 30, 2027, 178 days. A fall from here reaches CMAY’s buffer after 4.7% and ZMAY’s after 3.1%. Both track SPY, so what separates them is where each is in its own period.
CMAY
The fund's price can fall 4.7% from here before the buffer starts absorbing losses, by the issuer's number. In index terms, SPY can fall 4.7% from today's level to the point where the buffer begins. Protection left, in index points: 15.0% of the 15.0% buffer still sits below today's SPY level. 178 days remained on Nov 3, 2026. On Apr 30, 2027 the period ends and a new cap is set.
ZMAY
From its price on Nov 4, 2026, the fund can gain about 4.0% more before it reaches its cap. The fund's price can fall 3.1% from here before the buffer starts absorbing losses, by the issuer's number.

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.
