In plain words

Read the multiple against the whole window instead and 3 times GDX's 17.0% implies +50.9%, which makes GDXU look 25.5 points short. 15.6 of that is daily compounding, which happens to any 3 times fund over the same path, and the rest is the fund. GDXU aims to return +3 times GDX's move each day, then resets. Over one day it does that. Over longer, the daily results compound, so the total is not +3 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. GDX moved at 48% 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 about GDXU

Did GDXU return +3 times GDX?
Over the window to Sep 30, 2026, GDX moved +17.0% and GDXU returned +25.4%. 3 times that move is +50.9%, so the fund came out 25.5 points short of it.
Why does GDXU not return +3 times over a year?
Because it resets daily. GDXU 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.

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.
