These are two different products. CPRO is a floor fund, which caps how far a holder can fall. KNOV is a buffer fund, which absorbs the first part of a fall and leaves everything below it with the holder.
They do not reset together. KNOV has 8 days of its period left and CPRO has 342, so the two are not the same bet on the same months.
Where each one stands today
KNOV resets first, on Oct 31, 2026, 8 days from now; CPRO runs to Sep 30, 2027, 342 days. A fall from here reaches CPRO’s buffer after 0.2% and KNOV’s after 10.9%. Both track IWM, so what separates them is where each is in its own period.
