As of Nov 4, 2026. Source: ETFIQ.

These are two different products. XDEC is a floor fund, which caps how far a holder can fall. JANW 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

XDEC resets first, on Dec 18, 2026, 44 days from now; JANW runs to Dec 31, 2026, 57 days. JANW can still gain 1.9% before its cap, XDEC 0.9%. A fall from here reaches JANW’s buffer after 7.9% and XDEC’s after 8.4%. Both track SPY, so what separates them is where each is in its own period.

About each fund
JANW

SPY had already risen past this fund's cap of +10.5% 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 7.9% from here before the buffer starts absorbing losses, by the issuer's number. In index terms, SPY can fall 11.1% from today's level to the point where the buffer begins. Protection left, in index points: 20.0% of the 20.0% buffer still sits below today's SPY level. 57 days remained on Nov 4, 2026. On Dec 31, 2026 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.
