Which came closer to its stated multiple, MRVX or MVLL?

Over the window to Sep 30, 2026, MRVX finished 0.3 points from what its multiple implies and MVLL finished 18.8 points from its own, so MRVX came closer. Neither figure predicts the next window: it depends on how much the underlying moves about.

Are MRVX and MVLL levered on the same thing?

Yes. Both are levered on Marvell Technology, MRVX at +2 times and MVLL at +2 times the daily move.

Which one decays faster, MRVX or MVLL?

Decay follows how much the underlying moves about. Over this window MRVX’s moved at 54% annualized and MVLL’s at 82%, so MVLL has the rougher ride and, at the same multiple, loses more to compounding.

Can I hold MRVX or MVLL 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, MRVX or MVLL?

MRVX charges 1.29% a year and MVLL charges 1.50%, so MRVX is cheaper. Fees come from each fund's prospectus.

MRVX in plain words

One month to Sep 30, 2026: MRVX returned +50.0% where its own daily promise gave +51.8%, 1.8 points short. Read the multiple against the whole window instead and 2 times MRVL's 24.8% implies +49.7%, which makes MRVX look 0.3 points over. 2.2 of that is daily compounding, which happens to any 2 times fund over the same path, and the rest is the fund. MRVX aims to return +2 times MRVL'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. MRVL moved at 54% 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.

MVLL in plain words

Three months to Sep 30, 2026: MVLL returned −24.5% where its own daily promise gave −20.4%, 4.1 points short. Read the multiple against the whole window instead and 2 times MRVL's −2.9% implies −5.7%, which makes MVLL look 18.8 points short. 14.6 of that is daily compounding, which happens to any 2 times fund over the same path, and the rest is the fund. MVLL aims to return +2 times MRVL's move each day, then resets. MRVL moved at 82% annualized over that window.
