## Questions

### Did DOG return -1 times DIA?

Over the window to Sep 30, 2026, DIA moved −2.3% and DOG returned +3.6%. −1 times that move is +2.3%, so the fund came out 1.3 points ahead of it.

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

Because it resets daily. DOG 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.
