## Questions

### Did SMN return -2 times XLB?

Over the window to Sep 11, 2026, XLB moved −2.0% and SMN returned +4.5%. 2 times that move is +4.0%, so the fund came out 0.5 points ahead of it.

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

Because it resets daily. SMN 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.
