RMBC in plain words
One month to Sep 11, 2026: RMBC returned −28.2% where its own daily promise gave −27.1%, 1.1 points short. Read the multiple against the whole window instead and +2 times RMBS's −13.9% implies −27.8%, which makes RMBC look 0.4 points short. 0.7 of that is daily compounding, which happens to any +2 times fund over the same path, and the rest is the fund. RMBC aims to return +2 times RMBS'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. RMBS moved at 42% 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.

Questions people ask
- Which came closer to its stated multiple, RMBC or RMBX?
- Over the window to Sep 11, 2026, RMBC finished 0.4 points from what its multiple implies and RMBX finished 0.5 points from its own, so RMBC came closer. Neither figure predicts the next window: it depends on how much the underlying moves about.
- Are RMBC and RMBX levered on the same thing?
- Yes. Both are levered on RMBS, RMBC at +2 times and RMBX at +2 times the daily move.
- Which one decays faster, RMBC or RMBX?
- Decay follows how much the underlying moves about. Over this window RMBC’s moved at 42% annualized and RMBX’s at 42%, so RMBC has the rougher ride and, at the same multiple, loses more to compounding.
- Can I hold RMBC or RMBX 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, RMBC or RMBX?
- RMBC charges 0.45% a year and RMBX charges 1.49%, so RMBC is cheaper. Fees come from each fund's prospectus.
