BTCZ in plain words
Three months to Sep 30, 2026: BTCZ returned −53.7% where its own daily promise gave −54.2%, 0.5 points over. Read the multiple against the whole window instead and −2 times IBIT's 39.2% implies −78.5%, which makes BTCZ look 24.8 points over. 24.3 of that is daily compounding, which happens to any −2 times fund over the same path, and the rest is the fund. BTCZ aims to return -2 times IBIT'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. IBIT moved at 38% 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, BTCZ or SBIT?
- Over the window to Sep 30, 2026, BTCZ finished 24.8 points from what its multiple implies and SBIT finished 25.1 points from its own, so BTCZ came closer. Neither figure predicts the next window: it depends on how much the underlying moves about.
- Are BTCZ and SBIT levered on the same thing?
- Yes. Both are levered on bitcoin, BTCZ at -2 times and SBIT at -2 times the daily move.
- Which one decays faster, BTCZ or SBIT?
- Decay follows how much the underlying moves about. Over this window BTCZ’s moved at 38% annualized and SBIT’s at 38%, so BTCZ has the rougher ride and, at the same multiple, loses more to compounding.
- Can I hold BTCZ or SBIT 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.
