## Questions

### Did SDOW return -3 times DIA?

Over the window to Sep 11, 2026, DIA moved +2.9% and SDOW returned −7.0%. 3 times that move is −8.6%, so the fund came out 1.6 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.
