TBT in plain words

Three months to Sep 30, 2026: TBT returned +20.8% where its own daily promise gave +18.1%, 2.7 points over. Read the multiple against the whole window instead and −2 times TLT's −8.3% implies +16.7%, which makes TBT look 4.2 points over. 1.5 of that is daily compounding, which happens to any −2 times fund over the same path, and the rest is the fund. TBT aims to return -2 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 -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. 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.

TMF in plain words

Three months to Sep 30, 2026: TMF returned −25.3% where its own daily promise gave −23.6%, 1.8 points short. Read the multiple against the whole window instead and 3 times TLT's −8.3% implies −25.0%, which makes TMF look 0.3 points short. 1.4 of that is daily compounding, which happens to any 3 times fund over the same path, and the rest is the fund. TMF aims to return +3 times TLT's move each day, then resets. Over longer, the daily results compound, so the total is not +3 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, TBT or TMF?
Over the window to Sep 30, 2026, TBT finished 4.2 points from what its multiple implies and TMF finished 0.3 points from its own, so TMF came closer. Neither figure predicts the next window: it depends on how much the underlying moves about.
Are TBT and TMF levered on the same thing?
Yes. Both are levered on 20-year Treasuries, TBT at -2 times and TMF at +3 times the daily move.
Which one decays faster, TBT or TMF?
Decay follows how much the underlying moves about. Over this window TBT’s moved at 10% annualized and TMF’s at 10%, so TBT has the rougher ride and, at the same multiple, loses more to compounding.
Can I hold TBT or TMF 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, TBT or TMF?
TBT charges 0.93% a year and TMF charges 0.90%, so TMF is cheaper. Fees come from each fund's prospectus.
