RWM in plain words

Three months to Sep 30, 2026: RWM returned +8.6% where its own daily promise gave +7.0%, 1.6 points over. Read the multiple against the whole window instead and −1 times IWM's −6.9% implies +6.9%, which makes RWM look 1.7 points over. 0.0 of that is daily compounding, which happens to any −1 times fund over the same path, and the rest is the fund. RWM aims to return -1 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 -1 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 13% 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.

SRTY in plain words

Three months to Sep 30, 2026: SRTY returned +25.2% where its own daily promise gave +20.8%, 4.4 points over. Read the multiple against the whole window instead and −3 times IWM's −6.9% implies +20.8%, which makes SRTY look 4.5 points over. 0.0 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 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, RWM or SRTY?
Over the window to Sep 30, 2026, RWM finished 1.7 points from what its multiple implies and SRTY finished 4.5 points from its own, so RWM came closer. Neither figure predicts the next window: it depends on how much the underlying moves about.
Are RWM and SRTY levered on the same thing?
Yes. Both are levered on the Russell 2000, RWM at -1 times and SRTY at -3 times the daily move.
Which one decays faster, RWM or SRTY?
Decay follows how much the underlying moves about. Over this window RWM’s moved at 13% annualized and SRTY’s at 13%, so RWM has the rougher ride and, at the same multiple, loses more to compounding.
Can I hold RWM or SRTY 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, RWM or SRTY?
RWM charges 0.95% a year and SRTY charges 0.95%, so RWM is cheaper. Fees come from each fund's prospectus.
