Which came closer to its stated multiple, SIJ or UXI?

Over the window to Sep 30, 2026, SIJ finished 3.5 points from what its multiple implies and UXI finished 0.6 points from its own, so UXI came closer. Neither figure predicts the next window: it depends on how much the underlying moves about.

Are SIJ and UXI levered on the same thing?

Yes. Both are levered on State Street Industrial Select Sector SPDR ETF, SIJ at -2 times and UXI at +2 times the daily move.

Which one decays faster, SIJ or UXI?

Decay follows how much the underlying moves about. Over this window SIJ’s moved at 14% annualized and UXI’s at 14%, so SIJ has the rougher ride and, at the same multiple, loses more to compounding.

Can I hold SIJ or UXI 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, SIJ or UXI?

SIJ charges 0.95% a year and UXI charges 0.95%, so SIJ is cheaper. Fees come from each fund's prospectus.

SIJ in plain words

Three months to Sep 30, 2026: SIJ returned +20.9% where its own daily promise gave +18.0%, 2.8 points over. Read the multiple against the whole window instead and −2 times XLI's −8.7% implies +17.4%, which makes SIJ look 3.5 points over. 0.7 of that is daily compounding, which happens to any −2 times fund over the same path, and the rest is the fund. SIJ aims to return -2 times XLI'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. XLI moved at 14% 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.

UXI in plain words

Three months to Sep 30, 2026: UXI returned −18.0% where its own daily promise gave −17.1%, 0.9 points short. Read the multiple against the whole window instead and 2 times XLI's −8.7% implies −17.4%, which makes UXI look 0.6 points short. 0.3 of that is daily compounding, which happens to any 2 times fund over the same path, and the rest is the fund. UXI aims to return +2 times XLI'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.
