Side by side
As of Nov 4, 2026. Source: ETFIQ.
These are two different products. XBAP is a floor fund, which caps how far a holder can fall. MARM is a buffer fund, which absorbs the first part of a fall and leaves everything below it with the holder.
Both are already at their cap, so neither gains from more rise in the index before the period ends.
Where each one stands today
MARM resets first, on Mar 19, 2027, 135 days from now; XBAP runs to Mar 31, 2027, 147 days. MARM can still gain 1.9% before its cap, XBAP 3.6%. A fall from here reaches MARM’s buffer after 4.9% and XBAP’s after 10.0%. Both track SPY, so what separates them is where each is in its own period.

MARM
SPY had already risen past this fund's cap of +7.0% for the period on Nov 4, 2026, so in index terms there is no more upside to collect. The fund's own price can still drift up to about 1.9% as the period runs out. The fund's price can fall 4.9% from here before the buffer starts absorbing losses, by the issuer's number. In index terms, SPY can fall 15.4% from today's level to the point where the buffer begins. Protection left, in index points: 77.8% of the 77.8% buffer still sits below today's SPY level. 135 days remained on Nov 4, 2026. On Mar 19, 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.
