Which came closer to its stated multiple, BMNU or BMNZ?

Over the window to Sep 30, 2026, BMNU finished 3.2 points from what its multiple implies and BMNZ finished 89.5 points from its own, so BMNU came closer. Neither figure predicts the next window: it depends on how much the underlying moves about.

Are BMNU and BMNZ levered on the same thing?

Yes. Both are levered on BitMine Immersion Technologies, BMNU at +2 times and BMNZ at -2 times the daily move.

Which one decays faster, BMNU or BMNZ?

Decay follows how much the underlying moves about. Over this window BMNU’s moved at 81% annualized and BMNZ’s at 81%, so BMNU has the rougher ride and, at the same multiple, loses more to compounding.

Can I hold BMNU or BMNZ 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, BMNU or BMNZ?

BMNU charges 1.50% a year and BMNZ charges 1.40%, so BMNZ is cheaper. Fees come from each fund's prospectus.

BMNU in plain words

Three months to Sep 30, 2026: BMNU returned +176.8% where its own daily promise gave +198.0%, 21.2 points short. Read the multiple against the whole window instead and 2 times BMNR's 86.8% implies +173.6%, which makes BMNU look 3.2 points over. 24.5 of that is daily compounding, which happens to any 2 times fund over the same path, and the rest is the fund. BMNU aims to return +2 times BMNR'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. BMNR moved at 81% 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.

BMNZ in plain words

Three months to Sep 30, 2026: BMNZ returned −84.1% where its own daily promise gave −83.4%, 0.7 points short. Read the multiple against the whole window instead and −2 times BMNR's 86.8% implies −173.6%, which makes BMNZ look 89.5 points over. 90.2 of that is daily compounding, which happens to any −2 times fund over the same path, and the rest is the fund. BMNZ aims to return -2 times BMNR'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.
