## Questions

### Did UMDD return +3 times MDY?

Over the window to Sep 11, 2026, MDY moved −1.9% and UMDD returned −8.9%. 3 times that move is −5.8%, so the fund came out 3.1 points short of it.

### Why does UMDD not return +3 times over a year?

Because it resets daily. UMDD aims at +3 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 +3 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 +3x MDY 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 3 times the underlying's move. ETFIQ does not rate funds; the order is the arithmetic.
