BITI in plain words

Three months to Sep 30, 2026: BITI returned −29.6% where its own daily promise gave −30.9%, 1.2 points over. Read the multiple against the whole window instead and −1 times IBIT's 39.2% implies −39.2%, which makes BITI look 9.6 points over. 8.4 of that is daily compounding, which happens to any −1 times fund over the same path, and the rest is the fund. BITI aims to return -1 times IBIT's move each day, then resets. Over one day it does that. Over longer, the daily results compound, so the total is not -1 times the period's move: in a market that falls and comes back it is reliably less, and in a steady run it can be more. IBIT moved at 38% annualized over that window. That is what decides how far the two figures separate: the same fund on a calm underlying and a violent one is a different product.

BITX in plain words

Three months to Sep 30, 2026: BITX returned +82.3% where its own daily promise gave +87.1%, 4.8 points short. Read the multiple against the whole window instead and 2 times IBIT's 39.2% implies +78.5%, which makes BITX look 3.8 points over. 8.6 of that is daily compounding, which happens to any 2 times fund over the same path, and the rest is the fund. BITX aims to return +2 times IBIT's move each day, then resets. Over longer, the daily results compound, so the total is not +2 times the period's move: in a market that falls and comes back it is reliably less, and in a steady run it can be more.

Questions people ask

Which came closer to its stated multiple, BITI or BITX?
Over the window to Sep 30, 2026, BITI finished 9.6 points from what its multiple implies and BITX finished 3.8 points from its own, so BITX came closer. Neither figure predicts the next window: it depends on how much the underlying moves about.
Are BITI and BITX levered on the same thing?
Yes. Both are levered on bitcoin, BITI at -1 times and BITX at +2 times the daily move.
Which one decays faster, BITI or BITX?
Decay follows how much the underlying moves about. Over this window BITI’s moved at 38% annualized and BITX’s at 38%, so BITI has the rougher ride and, at the same multiple, loses more to compounding.
Can I hold BITI or BITX for a year?
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’s move, and in a market that falls and comes back it is reliably less. ETFIQ makes no recommendation either way.
Which is cheaper, BITI or BITX?
BITI charges 1.02% a year and BITX charges 2.75%, so BITI is cheaper. Fees come from each fund's prospectus.
