## Questions

### Did BITI return -1 times IBIT?

Over the window to Sep 11, 2026, IBIT moved +21.4% and BITI returned −19.1%. 1 times that move is −21.4%, so the fund came out 2.3 points ahead of it.

### Why does BITI not return -1 times over a year?

Because it resets daily. BITI aims at -1 times each day's move, and daily results compound. Over a run where the underlying falls and comes back, compounding a levered daily return leaves a holder behind what -1 times the period move would suggest; over a steady run in one direction it can leave them ahead. The longer the holding, and the more the underlying moves about, the further apart the two figures get.
