Method

In plain words

Read the multiple against the whole window instead and +2 times MU's −0.6% implies −1.3%, which makes MUU look 22.9 points short. 18.8 of that is daily compounding, which happens to any +2 times fund over the same path, and the rest is the fund. MUU aims to return +2 times MU's move each day, then resets. Over one day it does that. Over longer, the daily results compound, so the total is not +2 times the period's move: in a market that falls and comes back it is reliably less, and in a steady run it can be more. MU moved at 94% annualized over that window. That is what decides how far the two figures separate: the same fund on a calm underlying and a violent one is a different product.

Questions people ask

Did MUU return +2 times MU?
Over the window to Sep 11, 2026, MU moved −0.6% and MUU returned −24.2%. 2 times that move is −1.3%, so the fund came out 22.9 points short of it.
Why does MUU not return +2 times over a year?
Because it resets daily. MUU 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 MU ETF tracked its stated multiple most closely?
4 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.

The words on this page

Stated multiple
What the fund sets out to return against its underlying, each day. A fund at 2x aims to return twice the underlying’s daily move, and an inverse fund at -2x aims to return twice it in the opposite direction.
Daily reset
The fund starts each day aiming at the multiple again, from wherever it now stands. It is the mechanism that makes these funds behave as they do, and the reason the stated multiple applies to a day rather than to a holding period.
Compounding
Daily results multiply together rather than adding up. Two days of the multiple is not twice the multiple, and over a run of days the difference between the two grows with how far the underlying moves about.
Decay
What compounding costs a holder when the underlying falls and rises back to where it started. The underlying is level and the fund is down; the more violently it moved, the further down.
Difference against the stated multiple
The fund’s return minus the stated multiple times the underlying’s return, in percentage points. The one figure that says whether a holder got what the fund’s own multiple describes.
