DUG in plain words
Three months to Sep 11, 2026: DUG returned −23.7% where its own daily promise gave −25.7%, 2.0 points over. Read the multiple against the whole window instead and −2 times XLE's 14.0% implies −28.0%, which makes DUG look 4.3 points over. 2.3 of that is daily compounding, which happens to any −2 times fund over the same path, and the rest is the fund. DUG aims to return -2 times XLE'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. XLE moved at 22% 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.
XLEX in plain words
Three months to Sep 11, 2026: XLEX returned +24.9% where its own daily promise gave +28.5%, 3.6 points short. Read the multiple against the whole window instead and +2 times XLE's 14.0% implies +28.0%, which makes XLEX look 3.1 points short. 0.5 of that is daily compounding, which happens to any +2 times fund over the same path, and the rest is the fund. XLEX aims to return +2 times XLE'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, DUG or XLEX?
- Over the window to Sep 11, 2026, DUG finished 4.3 points from what its multiple implies and XLEX finished 3.1 points from its own, so XLEX came closer. Neither figure predicts the next window: it depends on how much the underlying moves about.
- Are DUG and XLEX levered on the same thing?
- Yes. Both are levered on energy, DUG at -2 times and XLEX at +2 times the daily move.
- Which one decays faster, DUG or XLEX?
- Decay follows how much the underlying moves about. Over this window DUG’s moved at 22% annualized and XLEX’s at 22%, so DUG has the rougher ride and, at the same multiple, loses more to compounding.
- Can I hold DUG or XLEX 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, DUG or XLEX?
- DUG charges 0.95% a year and XLEX charges 0.45%, so XLEX is cheaper. Fees come from each fund's prospectus.
