## Questions

### Did DUG return -2 times XLE?

Over the window to Sep 11, 2026, XLE moved +14.0% and DUG returned −23.7%. 2 times that move is −28.0%, so the fund came out 4.3 points ahead of it.

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

Because it resets daily. DUG 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.

### Which -2x XLE ETF tracked its stated multiple most closely?

2 issuers sell one. Over the days all of them have been trading, the table on this page ranks them by how far each finished from 2 times the underlying's move. ETFIQ does not rate funds; the order is the arithmetic.
