COIA in plain words
Three months to Sep 11, 2026: COIA returned +1.8% where its own daily promise gave +6.7%, 4.8 points short. Read the multiple against the whole window instead and +2 times COIN's 9.7% implies +19.4%, which makes COIA look 17.6 points short. 12.7 of that is daily compounding, which happens to any +2 times fund over the same path, and the rest is the fund. COIA aims to return +2 times COIN'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. COIN moved at 71% 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.
COIX in plain words
One month to Sep 11, 2026: COIX returned +30.0% where its own daily promise gave +31.3%, 1.3 points short. Read the multiple against the whole window instead and +2 times COIN's 17.6% implies +35.2%, which makes COIX look 5.2 points short. 3.9 of that is daily compounding, which happens to any +2 times fund over the same path, and the rest is the fund. COIX aims to return +2 times COIN's move each day, then resets. COIN moved at 81% annualized over that window.
Questions people ask
- Which came closer to its stated multiple, COIA or COIX?
- Over the window to Sep 11, 2026, COIA finished 17.6 points from what its multiple implies and COIX finished 5.2 points from its own, so COIX came closer. Neither figure predicts the next window: it depends on how much the underlying moves about.
- Are COIA and COIX levered on the same thing?
- Yes. Both are levered on Coinbase Global, COIA at +2 times and COIX at +2 times the daily move.
- Which one decays faster, COIA or COIX?
- Decay follows how much the underlying moves about. Over this window COIA’s moved at 71% annualized and COIX’s at 81%, so COIX has the rougher ride and, at the same multiple, loses more to compounding.
- Can I hold COIA or COIX 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, COIA or COIX?
- COIA charges 0.95% a year and COIX charges 0.45%, so COIX is cheaper. Fees come from each fund's prospectus.
