MSTX in plain words

Three months to Sep 30, 2026: MSTX returned +114.3% where its own daily promise gave +130.0%, 15.7 points short. Read the multiple against the whole window instead and 2 times MSTR's 63.9% implies +127.9%, which makes MSTX look 13.6 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. MSTX 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.

SMST in plain words

Three months to Sep 30, 2026: SMST returned −80.0% where its own daily promise gave −79.2%, 0.8 points short. Read the multiple against the whole window instead and −2 times MSTR's 63.9% implies −127.9%, which makes SMST look 47.9 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. SMST 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.

Questions people ask

Which came closer to its stated multiple, MSTX or SMST?
Over the window to Sep 30, 2026, MSTX finished 13.6 points from what its multiple implies and SMST finished 47.9 points from its own, so MSTX came closer. Neither figure predicts the next window: it depends on how much the underlying moves about.
Are MSTX and SMST levered on the same thing?
Yes. Both are levered on Strategy, MSTX at +2 times and SMST at -2 times the daily move.
Which one decays faster, MSTX or SMST?
Decay follows how much the underlying moves about. Over this window MSTX’s moved at 83% annualized and SMST’s at 83%, so MSTX has the rougher ride and, at the same multiple, loses more to compounding.
Can I hold MSTX or SMST 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, MSTX or SMST?
MSTX charges 1.31% a year and SMST charges 1.38%, so MSTX is cheaper. Fees come from each fund's prospectus.
