## Questions

### Did SCO return -2 times OILK?

Over the window to Sep 30, 2026, OILK moved +31.5% and SCO returned −45.1%. −2 times that move is −62.9%, so the fund came out 17.9 points ahead of it.

### Why does SCO not return -2 times over a year?

Because it resets daily. SCO aims at -2 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 -2 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.
