Which came closer to its stated multiple, ROM or XLKX?

Over the window to Sep 30, 2026, ROM finished 3.2 points from what its multiple implies and XLKX finished 4.1 points from its own, so ROM came closer. Neither figure predicts the next window: it depends on how much the underlying moves about.

Are ROM and XLKX levered on the same thing?

Yes. Both are levered on technology, ROM at +2 times and XLKX at +2 times the daily move.

Which one decays faster, ROM or XLKX?

Decay follows how much the underlying moves about. Over this window ROM’s moved at 26% annualized and XLKX’s at 26%, so ROM has the rougher ride and, at the same multiple, loses more to compounding.

Can I hold ROM or XLKX 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, ROM or XLKX?

ROM charges 0.93% a year and XLKX charges 0.45%, so XLKX is cheaper. Fees come from each fund's prospectus.

ROM in plain words

Three months to Sep 30, 2026: ROM returned +8.0% where its own daily promise gave +9.6%, 1.6 points short. Read the multiple against the whole window instead and 2 times XLK's 5.6% implies +11.2%, which makes ROM look 3.2 points short. 1.6 of that is daily compounding, which happens to any 2 times fund over the same path, and the rest is the fund. ROM aims to return +2 times XLK'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. XLK moved at 26% 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.

XLKX in plain words

Three months to Sep 30, 2026: XLKX returned +7.0% where its own daily promise gave +9.6%, 2.5 points short. Read the multiple against the whole window instead and 2 times XLK's 5.6% implies +11.2%, which makes XLKX look 4.1 points short. XLKX aims to return +2 times XLK's move each day, then resets.
