TWSC among the 470 leveraged ETFs, long, over three months
A percentile among the 125 inverse ETFs over three months. TWSC is a percentile among the 470 leveraged ETFs, long, over three months, a different set, so the two marks are not on one scale. It is a position in a set, not a rating, and neither end of it is a recommendation. All leveraged ETFs ranked by it → How it is computed →

STSM in plain words
Three months to Sep 30, 2026: STSM returned −13.9% where its own daily promise gave −13.8%, 0.1 points short. Read the multiple against the whole window instead and −2 times TSM's 3.0% implies −5.9%, which makes STSM look 8.0 points short. 7.9 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 34% 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.
TWSC in plain words
Three months to Sep 30, 2026: TWSC returned −0.9% where its own daily promise gave +3.0%, 3.9 points short. Read the multiple against the whole window instead and 2 times TSM's 3.0% implies +5.9%, which makes TWSC look 6.8 points short. 2.9 of that is daily compounding, which happens to any 2 times fund over the same path, and the rest is the fund. TWSC 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 TWSC?
- Over the window to Sep 30, 2026, STSM finished 8.0 points from what its multiple implies and TWSC finished 6.8 points from its own, so TWSC came closer. Neither figure predicts the next window: it depends on how much the underlying moves about.
- Are STSM and TWSC levered on the same thing?
- Yes. Both are levered on Taiwan Semiconductor Manufacturing, STSM at -2 times and TWSC at +2 times the daily move.
- Which one decays faster, STSM or TWSC?
- Decay follows how much the underlying moves about. Over this window STSM’s moved at 34% annualized and TWSC’s at 34%, so STSM has the rougher ride and, at the same multiple, loses more to compounding.
- Can I hold STSM or TWSC 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.
