Which came closer to its stated multiple, ASTX or ASUP?

Over the window to Sep 30, 2026, ASTX finished 0.4 points from what its multiple implies and ASUP finished 0.4 points from its own, so ASTX came closer. Neither figure predicts the next window: it depends on how much the underlying moves about.

Are ASTX and ASUP levered on the same thing?

Yes. Both are levered on AST SpaceMobile, ASTX at +2 times and ASUP at +2 times the daily move.

Which one decays faster, ASTX or ASUP?

Decay follows how much the underlying moves about. Over this window ASTX’s moved at 83% annualized and ASUP’s at 83%, so ASTX has the rougher ride and, at the same multiple, loses more to compounding.

Can I hold ASTX or ASUP 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, ASTX or ASUP?

ASTX charges 1.30% a year and ASUP charges 0.65%, so ASUP is cheaper. Fees come from each fund's prospectus.

ASTX in plain words

Three months to Sep 30, 2026: ASTX returned −62.9% where its own daily promise gave −61.2%, 1.7 points short. Read the multiple against the whole window instead and 2 times ASTS's −31.6% implies −63.3%, which makes ASTX look 0.4 points over. 2.1 of that is daily compounding, which happens to any 2 times fund over the same path, and the rest is the fund. ASTX aims to return +2 times ASTS'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. ASTS moved at 83% 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.

ASUP in plain words

Three months to Sep 30, 2026: ASUP returned −63.7% where its own daily promise gave −61.2%, 2.5 points short. Read the multiple against the whole window instead and 2 times ASTS's −31.6% implies −63.3%, which makes ASUP look 0.4 points short. ASUP aims to return +2 times ASTS's move each day, then resets.
