## Questions

### Did SKF return -2 times XLF?

Over the window to Sep 30, 2026, XLF moved −2.2% and SKF returned +5.7%. −2 times that move is +4.4%, so the fund came out 1.4 points ahead of it.

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

Because it resets daily. SKF 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.
