SMCX in plain words
Three months to Sep 11, 2026: SMCX returned +32.3% where its own daily promise gave +42.8%, 10.5 points short. Read the multiple against the whole window instead and +2 times SMCI's 31.6% implies +63.3%, which makes SMCX look 31.0 points short. 20.5 of that is daily compounding, which happens to any +2 times fund over the same path, and the rest is the fund. SMCX aims to return +2 times SMCI'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. SMCI moved at 95% 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.
SMCZ in plain words
Three months to Sep 11, 2026: SMCZ returned −73.9% where its own daily promise gave −72.3%, 1.6 points short. Read the multiple against the whole window instead and −2 times SMCI's 31.6% implies −63.3%, which makes SMCZ look 10.6 points short. 9.0 of that is daily compounding, which happens to any −2 times fund over the same path, and the rest is the fund. SMCZ aims to return -2 times SMCI'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, SMCX or SMCZ?
- Over the window to Sep 11, 2026, SMCX finished 31.0 points from what its multiple implies and SMCZ finished 10.6 points from its own, so SMCZ came closer. Neither figure predicts the next window: it depends on how much the underlying moves about.
- Are SMCX and SMCZ levered on the same thing?
- Yes. Both are levered on SMCI, SMCX at +2 times and SMCZ at -2 times the daily move.
- Which one decays faster, SMCX or SMCZ?
- Decay follows how much the underlying moves about. Over this window SMCX’s moved at 95% annualized and SMCZ’s at 95%, so SMCX has the rougher ride and, at the same multiple, loses more to compounding.
- Can I hold SMCX or SMCZ 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, SMCX or SMCZ?
- SMCX charges 1.32% a year and SMCZ charges 1.55%, so SMCX is cheaper. Fees come from each fund's prospectus.
