## Questions

### Did REK return -1 times IYR?

Over the window to Sep 11, 2026, IYR moved −3.0% and REK returned +4.8%. 1 times that move is +3.0%, so the fund came out 1.8 points ahead of it.

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

Because it resets daily. REK 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.
