As of Nov 4, 2026. Source: ETFIQ.

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

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

Where each one stands today

ARLU resets first, on Mar 31, 2027, 147 days from now; DDFA runs to Mar 31, 2027, 147 days. A fall from here reaches ARLU’s buffer after 12.1% and DDFA’s after 9.0%. Both track SPY, so what separates them is where each is in its own period.

About each fund
ARLU

This fund has no cap. It takes a share of any further rise in SPY. The fund's price can fall 12.1% from here before the buffer starts absorbing losses, by the issuer's number. In index terms, SPY can fall 15.2% 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. 147 days remained on Nov 4, 2026. On Mar 31, 2027 the period ends and new terms are set.

DDFA

SPY had already risen past this fund's cap of +13.4% 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 3.2% as the period runs out. The fund's price can fall 9.0% from here before the buffer starts absorbing losses, by the issuer's number. On Mar 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.
