Where each one stands today

BAUG resets first, on Jul 31, 2027, 313 days from now; CTAU runs to Jul 31, 2027, 316 days. A fall from here reaches BAUG’s buffer after 2.7% and CTAU’s after 0.5%. 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.
