Neither figure predicts the next window: it depends on how much the underlying moves about."}},{"@type":"Question","name":"Are SEF and XLFX levered on the same thing?","acceptedAnswer":{"@type":"Answer","text":"Yes. Both are levered on financials, SEF at -1 times and XLFX at +2 times the daily move."}},{"@type":"Question","name":"Which one decays faster, SEF or XLFX?","acceptedAnswer":{"@type":"Answer","text":"Decay follows how much the underlying moves about. Over this window SEF\u2019s moved at 13% annualized and XLFX\u2019s at 13%, so SEF has the rougher ride and, at the same multiple, loses more to compounding."}},{"@type":"Question","name":"Can I hold SEF or XLFX 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, SEF or XLFX?","acceptedAnswer":{"@type":"Answer","text":"SEF charges 0.95% a year and XLFX charges 0.45%, so XLFX 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":"SEF vs XLFX","item":"https://etfiq.com/compare/leverage/sef-vs-xlfx"}]},{"@type":"WebPage","name":"SEF vs XLFX: which held to its multiple?","description":"SEF sets out to return -1 times XLF each day and XLFX +2 times.
