UYM in plain words
Three months to Sep 11, 2026: UYM returned −6.3% where its own daily promise gave −4.6%, 1.7 points short. Read the multiple against the whole window instead and +2 times XLB's −2.0% implies −4.0%, which makes UYM look 2.3 points short. 0.7 of that is daily compounding, which happens to any +2 times fund over the same path, and the rest is the fund. UYM aims to return +2 times XLB'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. XLB moved at 17% 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.
XLBX in plain words
Three months to Sep 11, 2026: XLBX returned −7.3% where its own daily promise gave −4.6%, 2.7 points short. Read the multiple against the whole window instead and +2 times XLB's −2.0% implies −4.0%, which makes XLBX look 3.4 points short. XLBX aims to return +2 times XLB's move each day, then resets.
Questions people ask
- Which came closer to its stated multiple, UYM or XLBX?
- Over the window to Sep 11, 2026, UYM finished 2.3 points from what its multiple implies and XLBX finished 3.4 points from its own, so UYM came closer. Neither figure predicts the next window: it depends on how much the underlying moves about.
- Are UYM and XLBX levered on the same thing?
- Yes. Both are levered on Materials, UYM at +2 times and XLBX at +2 times the daily move.
- Which one decays faster, UYM or XLBX?
- Decay follows how much the underlying moves about. Over this window UYM’s moved at 17% annualized and XLBX’s at 17%, so UYM has the rougher ride and, at the same multiple, loses more to compounding.
- Can I hold UYM or XLBX 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, UYM or XLBX?
- UYM charges 0.95% a year and XLBX charges 0.45%, so XLBX is cheaper. Fees come from each fund's prospectus.
