DOG in plain words
Three months to Sep 11, 2026: DOG returned −1.7% where its own daily promise gave −3.1%, 1.4 points over. Read the multiple against the whole window instead and −1 times DIA's 2.9% implies −2.9%, which makes DOG look 1.1 points over. 0.2 of that is daily compounding, which happens to any −1 times fund over the same path, and the rest is the fund. DOG aims to return -1 times DIA's move each day, then resets. Over one day it does that. Over longer, the daily results compound, so the total is not -1 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. DIA moved at 11% 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.
SDOW in plain words
Three months to Sep 11, 2026: SDOW returned −7.0% where its own daily promise gave −9.9%, 2.9 points over. Read the multiple against the whole window instead and −3 times DIA's 2.9% implies −8.6%, which makes SDOW look 1.6 points over. 1.3 of that is daily compounding, which happens to any −3 times fund over the same path, and the rest is the fund. SDOW aims to return -3 times DIA's move each day, then resets. 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.
Questions people ask
- Which came closer to its stated multiple, DOG or SDOW?
- Over the window to Sep 11, 2026, DOG finished 1.1 points from what its multiple implies and SDOW finished 1.6 points from its own, so DOG came closer. Neither figure predicts the next window: it depends on how much the underlying moves about.
- Are DOG and SDOW levered on the same thing?
- Yes. Both are levered on the Dow 30, DOG at -1 times and SDOW at -3 times the daily move.
- Which one decays faster, DOG or SDOW?
- Decay follows how much the underlying moves about. Over this window DOG’s moved at 11% annualized and SDOW’s at 11%, so DOG has the rougher ride and, at the same multiple, loses more to compounding.
- Can I hold DOG or SDOW 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.
