STSM in plain words
Three months to Sep 11, 2026: STSM returned −17.7% where its own daily promise gave −17.4%, 0.3 points short. Read the multiple against the whole window instead and −2 times TSM's 2.2% implies −4.4%, which makes STSM look 13.3 points short. 13.0 of that is daily compounding, which happens to any −2 times fund over the same path, and the rest is the fund. STSM aims to return -2 times TSM'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. TSM moved at 45% 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.
TSMX in plain words
Three months to Sep 11, 2026: TSMX returned −3.2% where its own daily promise gave −0.5%, 2.7 points short. Read the multiple against the whole window instead and +2 times TSM's 2.2% implies +4.4%, which makes TSMX look 7.6 points short. 4.9 of that is daily compounding, which happens to any +2 times fund over the same path, and the rest is the fund. TSMX aims to return +2 times TSM'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, STSM or TSMX?
- Over the window to Sep 11, 2026, STSM finished 13.3 points from what its multiple implies and TSMX finished 7.6 points from its own, so TSMX came closer. Neither figure predicts the next window: it depends on how much the underlying moves about.
- Are STSM and TSMX levered on the same thing?
- Yes. Both are levered on TSM, STSM at -2 times and TSMX at +2 times the daily move.
- Which one decays faster, STSM or TSMX?
- Decay follows how much the underlying moves about. Over this window STSM’s moved at 45% annualized and TSMX’s at 45%, so STSM has the rougher ride and, at the same multiple, loses more to compounding.
- Can I hold STSM or TSMX 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, STSM or TSMX?
- STSM charges 1.30% a year and TSMX charges 0.99%, so TSMX is cheaper. Fees come from each fund's prospectus.
