SRTY in plain words
Three months to Sep 11, 2026: SRTY returned +4.2% where its own daily promise gave +0.7%, 3.5 points over. Read the multiple against the whole window instead and −3 times IWM's −1.1% implies +3.5%, which makes SRTY look 0.7 points over. 2.7 of that is daily compounding, which happens to any −3 times fund over the same path, and the rest is the fund. SRTY aims to return -3 times IWM's move each day, then resets. Over one day it does that. Over longer, the daily results compound, so the total is not -3 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. IWM moved at 14% 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.
URTY in plain words
Three months to Sep 11, 2026: URTY returned −7.0% where its own daily promise gave −4.7%, 2.3 points short. Read the multiple against the whole window instead and +3 times IWM's −1.1% implies −3.5%, which makes URTY look 3.6 points short. 1.3 of that is daily compounding, which happens to any +3 times fund over the same path, and the rest is the fund. URTY aims to return +3 times IWM's move each day, then resets. Over longer, the daily results compound, so the total is not +3 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, SRTY or URTY?
- Over the window to Sep 11, 2026, SRTY finished 0.7 points from what its multiple implies and URTY finished 3.6 points from its own, so SRTY came closer. Neither figure predicts the next window: it depends on how much the underlying moves about.
- Are SRTY and URTY levered on the same thing?
- Yes. Both are levered on the Russell 2000, SRTY at -3 times and URTY at +3 times the daily move.
- Which one decays faster, SRTY or URTY?
- Decay follows how much the underlying moves about. Over this window SRTY’s moved at 14% annualized and URTY’s at 14%, so SRTY has the rougher ride and, at the same multiple, loses more to compounding.
- Can I hold SRTY or URTY 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, SRTY or URTY?
- SRTY charges 0.95% a year and URTY charges 0.95%, so SRTY is cheaper. Fees come from each fund's prospectus.
