## Questions

### Did SDOW return -3 times DIA?

Over the window to Sep 30, 2026, DIA moved −2.3% and SDOW returned +9.1%. −3 times that move is +7.0%, so the fund came out 2.1 points ahead of it.

### Why does SDOW not return -3 times over a year?

Because it resets daily. SDOW aims at -3 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 -3 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.
