Which came closer to its stated multiple, MSTU or MSTZ?

Over the window to Sep 30, 2026, MSTU finished 10.9 points from what its multiple implies and MSTZ finished 48.5 points from its own, so MSTU came closer. Neither figure predicts the next window: it depends on how much the underlying moves about.

Are MSTU and MSTZ levered on the same thing?

Yes. Both are levered on Strategy, MSTU at +2 times and MSTZ at -2 times the daily move.

Which one decays faster, MSTU or MSTZ?

Decay follows how much the underlying moves about. Over this window MSTU’s moved at 83% annualized and MSTZ’s at 83%, so MSTU has the rougher ride and, at the same multiple, loses more to compounding.

Can I hold MSTU or MSTZ 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, MSTU or MSTZ?

MSTU charges 1.05% a year and MSTZ charges 1.05%, so MSTU is cheaper. Fees come from each fund's prospectus.

MSTU in plain words

Three months to Sep 30, 2026: MSTU returned +117.0% where its own daily promise gave +130.0%, 13.1 points short. Read the multiple against the whole window instead and 2 times MSTR's 63.9% implies +127.9%, which makes MSTU look 10.9 points short. 2.2 of that is daily compounding, which happens to any 2 times fund over the same path, and the rest is the fund. MSTU aims to return +2 times MSTR'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. MSTR moved at 83% 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.

MSTZ in plain words

Three months to Sep 30, 2026: MSTZ returned −79.3% where its own daily promise gave −79.2%, 0.1 points short. Read the multiple against the whole window instead and −2 times MSTR's 63.9% implies −127.9%, which makes MSTZ look 48.5 points over. 48.7 of that is daily compounding, which happens to any −2 times fund over the same path, and the rest is the fund. MSTZ aims to return -2 times MSTR'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.
