CPST vs TOCT: which one stands where?
As of Oct 1, 2026 TOCT can fall 4.8% before its buffer engages and CPST 0.1%, and CPST resets 30 days sooner. Calamos S&P 500 ® Structured Alt Protection ETF - September and Innovator Equity Defined Protection ETF - Oct 2027.
CPST: reference +0.1% since period start, fund 0.0%; buffer −0 to floor; cap +8.0%; Full floor.
TOCT: reference +14.5% since period start, fund +4.2%; buffer Floor; cap +12.8%; At its cap.
TOCT is already at its cap, so more rise in the index adds nothing to it before the period ends.
They do not reset together. CPST has 335 days of its period left and TOCT has 365, so the two are not the same bet on the same months.
Where each one stands today
CPST resets first, on Sep 1, 2027, 335 days from now; TOCT runs to Sep 30, 2027, 365 days. A fall from here reaches CPST’s buffer after 0.1% and TOCT’s after 4.8%. 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.
