Neither figure predicts the next window: it depends on how much the underlying moves about."}},{"@type":"Question","name":"Are MYY and UMDD levered on the same thing?","acceptedAnswer":{"@type":"Answer","text":"Yes. Both are levered on the S&P MidCap 400, MYY at -1 times and UMDD at +3 times the daily move."}},{"@type":"Question","name":"Which one decays faster, MYY or UMDD?","acceptedAnswer":{"@type":"Answer","text":"Decay follows how much the underlying moves about. Over this window MYY\u2019s moved at 12% annualized and UMDD\u2019s at 12%, so MYY has the rougher ride and, at the same multiple, loses more to compounding."}},{"@type":"Question","name":"Can I hold MYY or UMDD 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, MYY or UMDD?","acceptedAnswer":{"@type":"Answer","text":"MYY charges 0.95% a year and UMDD charges 0.95%, so MYY 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":"MYY vs UMDD","item":"https://etfiq.com/compare/leverage/myy-vs-umdd"}]},{"@type":"WebPage","name":"MYY vs UMDD: which held to its multiple?","description":"MYY sets out to return -1 times MDY each day and UMDD +3 times.
