Which came closer to its stated multiple, UMCU or UMCX?

Over the window to Sep 30, 2026, UMCU finished 0.7 points from what its multiple implies and UMCX finished 14.7 points from its own, so UMCU came closer. Neither figure predicts the next window: it depends on how much the underlying moves about.

Are UMCU and UMCX levered on the same thing?

Yes. Both are levered on United Microelectronics, UMCU at +2 times and UMCX at +2 times the daily move.

Which one decays faster, UMCU or UMCX?

Decay follows how much the underlying moves about. Over this window UMCU’s moved at 52% annualized and UMCX’s at 66%, so UMCX has the rougher ride and, at the same multiple, loses more to compounding.

Can I hold UMCU or UMCX 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, UMCU or UMCX?

UMCU charges 1.49% a year and UMCX charges 0.45%, so UMCX is cheaper. Fees come from each fund's prospectus.

UMCU in plain words

One month to Sep 30, 2026: UMCU returned +45.7% where its own daily promise gave +48.3%, 2.6 points short. Read the multiple against the whole window instead and 2 times UMC's 23.2% implies +46.4%, which makes UMCU look 0.7 points short. 1.9 of that is daily compounding, which happens to any 2 times fund over the same path, and the rest is the fund. UMCU aims to return +2 times UMC'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. UMC moved at 52% 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.

UMCX in plain words

Three months to Sep 30, 2026: UMCX returned −21.0% where its own daily promise gave −16.1%, 4.8 points short. Read the multiple against the whole window instead and 2 times UMC's −3.2% implies −6.3%, which makes UMCX look 14.7 points short. 9.8 of that is daily compounding, which happens to any 2 times fund over the same path, and the rest is the fund. UMCX aims to return +2 times UMC's move each day, then resets. UMC moved at 66% annualized over that window.
