Which came closer to its stated multiple, DDM or SDOW?

Over the window to Sep 30, 2026, DDM finished 1.7 points from what its multiple implies and SDOW finished 2.1 points from its own, so DDM came closer. Neither figure predicts the next window: it depends on how much the underlying moves about.

Are DDM and SDOW levered on the same thing?

Yes. Both are levered on the Dow 30, DDM at +2 times and SDOW at -3 times the daily move.

Which one decays faster, DDM or SDOW?

Decay follows how much the underlying moves about. Over this window DDM’s moved at 12% annualized and SDOW’s at 12%, so DDM has the rougher ride and, at the same multiple, loses more to compounding.

Can I hold DDM 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.

Which is cheaper, DDM or SDOW?

DDM charges 0.95% a year and SDOW charges 0.95%, so DDM is cheaper. Fees come from each fund's prospectus.

DDM in plain words

Three months to Sep 30, 2026: DDM returned −6.3% where its own daily promise gave −4.9%, 1.4 points short. Read the multiple against the whole window instead and 2 times DIA's −2.3% implies −4.6%, which makes DDM look 1.7 points short. 0.3 of that is daily compounding, which happens to any 2 times fund over the same path, and the rest is the fund. DDM aims to return +2 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 +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. DIA moved at 12% 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 30, 2026: SDOW returned +9.1% where its own daily promise gave +5.1%, 4.0 points over. Read the multiple against the whole window instead and −3 times DIA's −2.3% implies +7.0%, which makes SDOW look 2.1 points over. 1.8 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.
