DULL in plain words
Three months to Sep 11, 2026: DULL returned −15.8% where its own daily promise gave −17.0%, 1.2 points over. Read the multiple against the whole window instead and −3 times GLD's 3.2% implies −9.5%, which makes DULL look 6.4 points short. 7.5 of that is daily compounding, which happens to any −3 times fund over the same path, and the rest is the fund. DULL aims to return -3 times GLD'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. GLD moved at 25% 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.
GLL in plain words
Three months to Sep 11, 2026: GLL returned −7.8% where its own daily promise gave −10.3%, 2.5 points over. Read the multiple against the whole window instead and −2 times GLD's 3.2% implies −6.3%, which makes GLL look 1.5 points short. 4.0 of that is daily compounding, which happens to any −2 times fund over the same path, and the rest is the fund. GLL aims to return -2 times GLD's move each day, then resets. 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.
Questions people ask
- Which came closer to its stated multiple, DULL or GLL?
- Over the window to Sep 11, 2026, DULL finished 6.4 points from what its multiple implies and GLL finished 1.5 points from its own, so GLL came closer. Neither figure predicts the next window: it depends on how much the underlying moves about.
- Are DULL and GLL levered on the same thing?
- Yes. Both are levered on gold, DULL at -3 times and GLL at -2 times the daily move.
- Which one decays faster, DULL or GLL?
- Decay follows how much the underlying moves about. Over this window DULL’s moved at 25% annualized and GLL’s at 25%, so DULL has the rougher ride and, at the same multiple, loses more to compounding.
- Can I hold DULL or GLL for a year?
- Both reset every day, so the multiple in the name applies to a single day and the daily results compound. Over a year the total is not the multiple times the year’s move, and in a market that falls and comes back it is reliably less. ETFIQ makes no recommendation either way.
