## Questions

### Did RMBC return +2 times RMBS?

Over the window to Sep 30, 2026, RMBS moved −13.8% and RMBC returned −35.5%. 2 times that move is −27.6%, so the fund came out 7.9 points short of it.

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

Because it resets daily. RMBC 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 RMBS 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 figure itself.
