Where each one stands today
MARM resets first, on Mar 19, 2027, 179 days from now; ARLU runs to Mar 31, 2027, 192 days. A fall from here reaches ARLU’s buffer after 13.1% and MARM’s after 4.3%. 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.
