As of Nov 4, 2026. Source: ETFIQ.

These are two different products. PMFB is a floor fund, which caps how far a holder can fall. FEBU is a buffer fund, which absorbs the first part of a fall and leaves everything below it with the holder.

PMFB is already at its cap, so more rise in the index adds nothing to it before the period ends.

Where each one stands today

FEBU resets first, on Jan 31, 2027, 88 days from now; PMFB runs to Jan 31, 2027, 88 days. A fall from here reaches FEBU’s buffer after 7.4% and PMFB’s after 4.5%. Both track SPY, so what separates them is where each is in its own period.

About each fund
FEBU

This fund has no cap. It takes a share of any further rise in SPY. The fund's price can fall 7.4% from here before the buffer starts absorbing losses, by the issuer's number. In index terms, SPY can fall 9.8% 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. 88 days remained on Nov 4, 2026. On Jan 31, 2027 the period ends and new terms are set.

PMFB

SPY had already risen past this fund's cap of +6.8% 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 2.1% as the period runs out. The fund's price can fall 4.5% from here before the buffer starts absorbing losses, by the issuer's number. Protection left, in index points: 100.0% of the 100.0% buffer still sits below today's SPY level. On Jan 31, 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.
