CJUN vs CPSM: which one stands where?

As of Oct 1, 2026 CPSM can fall 2.1% before its buffer engages and CJUN 0.5%, and CPSM resets 31 days sooner. Corgi U.S. Equities 15% Structured Buffer ETF and Calamos S&P 500 ® Structured Alt Protection ETF - May.

CJUNBetween buffer and cap

CJUN: reference +0.5% since period start, fund +1.9%; buffer 0 to −15; cap +13.9%; Between buffer and cap.

CPSMFull floor

CPSM: reference +5.8% since period start, fund +1.9%; buffer −0 to floor; cap +6.5%; Full floor.

These are two different products. CPSM is a floor fund, which caps how far a holder can fall. CJUN 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. CPSM has 212 days of its period left and CJUN has 243, so the two are not the same bet on the same months.

Where each one stands today

CPSM resets first, on May 1, 2027, 212 days from now; CJUN runs to May 31, 2027, 243 days. A fall from here reaches CJUN’s buffer after 0.5% and CPSM’s after 2.1%. Both track SPY, so what separates them is where each is in its own period.

Every figure is ETFIQ’s own, from the issuer’s published outcome-period terms. A buffer ETF holds FLEX options on its reference index rather than shares, so there is no holdings overlap between two of them to report.
