## Questions

### Did UST return +2 times IEF?

Over the window to Sep 11, 2026, IEF moved −2.4% and UST returned −5.5%. 2 times that move is −4.7%, so the fund came out 0.8 points short of it.

### Why does UST not return +2 times over a year?

Because it resets daily. UST 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.
