Neither figure predicts the next window: it depends on how much the underlying moves about."}},{"@type":"Question","name":"Are BIB and BIS levered on the same thing?","acceptedAnswer":{"@type":"Answer","text":"Yes. Both are levered on iShares Biotechnology ETF, BIB at +2 times and BIS at -2 times the daily move."}},{"@type":"Question","name":"Which one decays faster, BIB or BIS?","acceptedAnswer":{"@type":"Answer","text":"Decay follows how much the underlying moves about. Over this window BIB\u2019s moved at 24% annualized and BIS\u2019s at 24%, so BIB has the rougher ride and, at the same multiple, loses more to compounding."}},{"@type":"Question","name":"Can I hold BIB or BIS 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, BIB or BIS?","acceptedAnswer":{"@type":"Answer","text":"BIB charges 0.95% a year and BIS charges 0.95%, so BIB is cheaper.
