SOFC in plain words
One month to Sep 11, 2026: SOFC returned −10.2% where its own daily promise gave −8.8%, 1.3 points short. Read the multiple against the whole window instead and +2 times SOFI's −3.5% implies −6.9%, which makes SOFC look 3.2 points short. 1.9 of that is daily compounding, which happens to any +2 times fund over the same path, and the rest is the fund. SOFC aims to return +2 times SOFI'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. SOFI moved at 52% 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.
SOFX in plain words
Three months to Sep 11, 2026: SOFX returned −4.3% where its own daily promise gave +1.7%, 6.0 points short. Read the multiple against the whole window instead and +2 times SOFI's 4.5% implies +8.9%, which makes SOFX look 13.3 points short. 7.2 of that is daily compounding, which happens to any +2 times fund over the same path, and the rest is the fund. SOFX aims to return +2 times SOFI's move each day, then resets. SOFI moved at 54% annualized over that window.
Questions people ask
- Which came closer to its stated multiple, SOFC or SOFX?
- Over the window to Sep 11, 2026, SOFC finished 3.2 points from what its multiple implies and SOFX finished 13.3 points from its own, so SOFC came closer. Neither figure predicts the next window: it depends on how much the underlying moves about.
- Are SOFC and SOFX levered on the same thing?
- Yes. Both are levered on SOFI, SOFC at +2 times and SOFX at +2 times the daily move.
- Which one decays faster, SOFC or SOFX?
- Decay follows how much the underlying moves about. Over this window SOFC’s moved at 52% annualized and SOFX’s at 54%, so SOFX has the rougher ride and, at the same multiple, loses more to compounding.
- Can I hold SOFC or SOFX 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.
