RKLX in plain words
Three months to Sep 11, 2026: RKLX returned −70.2% where its own daily promise gave −68.0%, 2.2 points short. Read the multiple against the whole window instead and +2 times RKLB's −38.5% implies −77.0%, which makes RKLX look 6.8 points over. 9.1 of that is daily compounding, which happens to any +2 times fund over the same path, and the rest is the fund. RKLX aims to return +2 times RKLB'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. RKLB moved at 80% 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.
RKX in plain words
One month to Sep 11, 2026: RKX returned −41.5% where its own daily promise gave −40.9%, 0.7 points short. Read the multiple against the whole window instead and +2 times RKLB's −22.4% implies −44.9%, which makes RKX look 3.4 points over. 4.0 of that is daily compounding, which happens to any +2 times fund over the same path, and the rest is the fund. RKX aims to return +2 times RKLB's move each day, then resets. RKLB moved at 39% annualized over that window.
Questions people ask
- Which came closer to its stated multiple, RKLX or RKX?
- Over the window to Sep 11, 2026, RKLX finished 6.8 points from what its multiple implies and RKX finished 3.4 points from its own, so RKX came closer. Neither figure predicts the next window: it depends on how much the underlying moves about.
- Are RKLX and RKX levered on the same thing?
- Yes. Both are levered on RKLB, RKLX at +2 times and RKX at +2 times the daily move.
- Which one decays faster, RKLX or RKX?
- Decay follows how much the underlying moves about. Over this window RKLX’s moved at 80% annualized and RKX’s at 39%, so RKLX has the rougher ride and, at the same multiple, loses more to compounding.
- Can I hold RKLX or RKX 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, RKLX or RKX?
- RKLX charges 1.63% a year and RKX charges 0.45%, so RKX is cheaper. Fees come from each fund's prospectus.
