Which came closer to its stated multiple, IONX or IONZ?

Over the window to Sep 30, 2026, IONX finished 12.7 points from what its multiple implies and IONZ finished 55.5 points from its own, so IONX came closer. Neither figure predicts the next window: it depends on how much the underlying moves about.

Are IONX and IONZ levered on the same thing?

Yes. Both are levered on IONQ, IONX at +2 times and IONZ at -2 times the daily move.

Which one decays faster, IONX or IONZ?

Decay follows how much the underlying moves about. Over this window IONX’s moved at 76% annualized and IONZ’s at 76%, so IONX has the rougher ride and, at the same multiple, loses more to compounding.

Can I hold IONX or IONZ 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, IONX or IONZ?

IONX charges 1.38% a year and IONZ charges 1.91%, so IONX is cheaper. Fees come from each fund's prospectus.

IONX in plain words

Three months to Sep 30, 2026: IONX returned −42.0% where its own daily promise gave −36.9%, 5.1 points short. Read the multiple against the whole window instead and 2 times IONQ's −14.7% implies −29.3%, which makes IONX look 12.7 points short. 7.5 of that is daily compounding, which happens to any 2 times fund over the same path, and the rest is the fund. IONX aims to return +2 times IONQ'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. IONQ moved at 76% 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.

IONZ in plain words

Three months to Sep 30, 2026: IONZ returned −26.1% where its own daily promise gave −12.1%, 14.0 points short. Read the multiple against the whole window instead and −2 times IONQ's −14.7% implies +29.3%, which makes IONZ look 55.5 points short. 41.5 of that is daily compounding, which happens to any −2 times fund over the same path, and the rest is the fund. IONZ aims to return -2 times IONQ'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.
