Side by side
As of Nov 4, 2026. Source: ETFIQ.
These are two different products. CPSY is a floor fund, which caps how far a holder can fall. JANU is a buffer fund, which absorbs the first part of a fall and leaves everything below it with the holder.
CPSY is already at its cap, so more rise in the index adds nothing to it before the period ends.
Where each one stands today
CPSY resets first, on Dec 31, 2026, 57 days from now; JANU runs to Dec 31, 2026, 57 days. A fall from here reaches CPSY’s buffer after 5.0% and JANU’s after 8.4%. Both track SPY, so what separates them is where each is in its own period.
CPSY
SPY had already risen past this fund's cap of +6.4% for the period on Nov 4, 2026, so in index terms there is no more upside to collect. The fund's price can fall 5.0% from here before the buffer starts absorbing losses, by the issuer's number. In index terms, SPY can fall 10.9% from today's level to the point where the buffer begins. Protection left, in index points: 100.0% of the 100.0% 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.
JANU
This fund has no cap. It takes a share of any further rise in SPY. The fund's price can fall 8.4% 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: 15.0% of the 15.0% buffer still sits below today's SPY level. On Dec 31, 2026 the period ends and new terms are 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.
