MUU in plain words
Three months to Sep 11, 2026: MUU returned −24.2% where its own daily promise gave −20.1%, 4.1 points short. Read the multiple against the whole window instead and +2 times MU's −0.6% implies −1.3%, which makes MUU look 22.9 points short. 18.8 of that is daily compounding, which happens to any +2 times fund over the same path, and the rest is the fund. MUU aims to return +2 times MU'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. MU moved at 94% 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.
MUZ in plain words
Three months to Sep 11, 2026: MUZ returned −52.0% where its own daily promise gave −48.9%, 3.1 points short. Read the multiple against the whole window instead and −2 times MU's −0.6% implies +1.3%, which makes MUZ look 53.3 points short. 50.1 of that is daily compounding, which happens to any −2 times fund over the same path, and the rest is the fund. MUZ aims to return -2 times MU'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, MUU or MUZ?
- Over the window to Sep 11, 2026, MUU finished 22.9 points from what its multiple implies and MUZ finished 53.3 points from its own, so MUU came closer. Neither figure predicts the next window: it depends on how much the underlying moves about.
- Are MUU and MUZ levered on the same thing?
- Yes. Both are levered on MU, MUU at +2 times and MUZ at -2 times the daily move.
- Which one decays faster, MUU or MUZ?
- Decay follows how much the underlying moves about. Over this window MUU’s moved at 94% annualized and MUZ’s at 94%, so MUU has the rougher ride and, at the same multiple, loses more to compounding.
- Can I hold MUU or MUZ 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, MUU or MUZ?
- MUU charges 1.01% a year and MUZ charges 1.31%, so MUU is cheaper. Fees come from each fund's prospectus.
