Neither figure predicts the next window: it depends on how much the underlying moves about."}},{"@type":"Question","name":"Are RMBC and RMBX levered on the same thing?","acceptedAnswer":{"@type":"Answer","text":"Yes. Both are levered on Rambus, RMBC at +2 times and RMBX at +2 times the daily move."}},{"@type":"Question","name":"Which one decays faster, RMBC or RMBX?","acceptedAnswer":{"@type":"Answer","text":"Decay follows how much the underlying moves about. Over this window RMBC\u2019s moved at 67% annualized and RMBX\u2019s at 67%, so RMBC has the rougher ride and, at the same multiple, loses more to compounding."}},{"@type":"Question","name":"Can I hold RMBC or RMBX for a year?","acceptedAnswer":{"@type":"Answer","text":"Both reset every day, so the multiple in the name applies to a single day and the daily results compound. Over a year the total is not the multiple times the year\u2019s move, and in a market that falls and comes back it is reliably less. ETFIQ makes no recommendation either way."}},{"@type":"Question","name":"Which is cheaper, RMBC or RMBX?","acceptedAnswer":{"@type":"Answer","text":"RMBC charges 0.45% a year and RMBX charges 1.49%, so RMBC is cheaper. Fees come from each fund's prospectus."}}]},{"@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"name":"ETFIQ","item":"https://etfiq.com/"},{"@type":"ListItem","position":2,"name":"Leveraged ETFs","item":"https://etfiq.com/leverage/"},{"@type":"ListItem","position":3,"name":"RMBC vs RMBX","item":"https://etfiq.com/compare/leverage/rmbc-vs-rmbx"}]},{"@type":"WebPage","name":"RMBC vs RMBX: which held to its multiple?","description":"RMBC sets out to return +2 times RMBS each day and RMBX +2 times.
