SMRX in plain words

One month to Sep 30, 2026: SMRX returned −34.4% where its own daily promise gave −33.3%, 1.1 points short. Read the multiple against the whole window instead and 2 times SMR's −14.8% implies −29.6%, which makes SMRX look 4.8 points short. 3.7 of that is daily compounding, which happens to any 2 times fund over the same path, and the rest is the fund. SMRX aims to return +2 times SMR'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. SMR moved at 97% 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.

SMU in plain words

Three months to Sep 30, 2026: SMU returned −53.7% where its own daily promise gave −50.5%, 3.2 points short. Read the multiple against the whole window instead and 2 times SMR's −22.2% implies −44.3%, which makes SMU look 9.4 points short. 6.2 of that is daily compounding, which happens to any 2 times fund over the same path, and the rest is the fund. SMU aims to return +2 times SMR's move each day, then resets. SMR moved at 89% annualized over that window.

Questions people ask

Which came closer to its stated multiple, SMRX or SMU?
Over the window to Sep 30, 2026, SMRX finished 4.8 points from what its multiple implies and SMU finished 9.4 points from its own, so SMRX came closer. Neither figure predicts the next window: it depends on how much the underlying moves about.
Are SMRX and SMU levered on the same thing?
Yes. Both are levered on NuScale Power, SMRX at +2 times and SMU at +2 times the daily move.
Which one decays faster, SMRX or SMU?
Decay follows how much the underlying moves about. Over this window SMRX’s moved at 97% annualized and SMU’s at 89%, so SMRX has the rougher ride and, at the same multiple, loses more to compounding.
Can I hold SMRX or SMU 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, SMRX or SMU?
SMRX charges 0.45% a year and SMU charges 1.30%, so SMRX is cheaper. Fees come from each fund's prospectus.
