MSTC in plain words
One month to Sep 11, 2026: MSTC returned +72.0% where its own daily promise gave +75.7%, 3.6 points short. Read the multiple against the whole window instead and +2 times MSTR's 38.1% implies +76.2%, which makes MSTC look 4.2 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. MSTC 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 104% 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 11, 2026: MSTZ returned −51.5% where its own daily promise gave −51.1%, 0.4 points short. Read the multiple against the whole window instead and −2 times MSTR's 5.7% implies −11.3%, which makes MSTZ look 40.2 points short. 39.8 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. MSTR moved at 88% annualized over that window.
Questions people ask
- Which came closer to its stated multiple, MSTC or MSTZ?
- Over the window to Sep 11, 2026, MSTC finished 4.2 points from what its multiple implies and MSTZ finished 40.2 points from its own, so MSTC came closer. Neither figure predicts the next window: it depends on how much the underlying moves about.
- Are MSTC and MSTZ levered on the same thing?
- Yes. Both are levered on Strategy, MSTC at +2 times and MSTZ at -2 times the daily move.
- Which one decays faster, MSTC or MSTZ?
- Decay follows how much the underlying moves about. Over this window MSTC’s moved at 104% annualized and MSTZ’s at 88%, so MSTC has the rougher ride and, at the same multiple, loses more to compounding.
- Can I hold MSTC 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, MSTC or MSTZ?
- MSTC charges 0.45% a year and MSTZ charges 1.05%, so MSTC is cheaper. Fees come from each fund's prospectus.
