TBF among the 125 inverse ETFs over three months
UBT among the 470 leveraged ETFs, long, over three months
A percentile among the 125 inverse ETFs over three months. UBT is a percentile among the 470 leveraged ETFs, long, over three months, a different set, so the two marks are not on one scale. It is a position in a set, not a rating, and neither end of it is a recommendation. All leveraged ETFs ranked by it → How it is computed →

TBF in plain words
Three months to Sep 30, 2026: TBF returned +10.6% where its own daily promise gave +8.8%, 1.8 points over. Read the multiple against the whole window instead and −1 times TLT's −8.3% implies +8.3%, which makes TBF look 2.3 points over. 0.5 of that is daily compounding, which happens to any −1 times fund over the same path, and the rest is the fund. TBF aims to return -1 times TLT'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. TLT moved at 10% 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.
UBT in plain words
Three months to Sep 30, 2026: UBT returned −16.6% where its own daily promise gave −16.2%, 0.4 points short. Read the multiple against the whole window instead and 2 times TLT's −8.3% implies −16.7%, which makes UBT look 0.1 points over. 0.5 of that is daily compounding, which happens to any 2 times fund over the same path, and the rest is the fund. UBT aims to return +2 times TLT'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, TBF or UBT?
- Over the window to Sep 30, 2026, TBF finished 2.3 points from what its multiple implies and UBT finished 0.1 points from its own, so UBT came closer. Neither figure predicts the next window: it depends on how much the underlying moves about.
- Are TBF and UBT levered on the same thing?
- Yes. Both are levered on 20-year Treasuries, TBF at -1 times and UBT at +2 times the daily move.
- Which one decays faster, TBF or UBT?
- Decay follows how much the underlying moves about. Over this window TBF’s moved at 10% annualized and UBT’s at 10%, so TBF has the rougher ride and, at the same multiple, loses more to compounding.
- Can I hold TBF or UBT 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.
