Where each one stands today

UAUG resets first, on Jul 31, 2027, 313 days from now; CTAU runs to Jul 31, 2027, 316 days. A fall from here reaches CTAU’s buffer after 0.5% and UAUG’s after 6.9%. 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.
