SKF in plain words
Three months to Sep 11, 2026: SKF returned −12.5% where its own daily promise gave −14.8%, 2.3 points over. Read the multiple against the whole window instead and −2 times XLF's 7.7% implies −15.4%, which makes SKF look 2.9 points over. 0.6 of that is daily compounding, which happens to any −2 times fund over the same path, and the rest is the fund. SKF aims to return -2 times XLF'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. XLF moved at 13% 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.
UYG in plain words
Three months to Sep 11, 2026: UYG returned +13.8% where its own daily promise gave +15.5%, 1.7 points short. Read the multiple against the whole window instead and +2 times XLF's 7.7% implies +15.4%, which makes UYG look 1.6 points short. 0.1 of that is daily compounding, which happens to any +2 times fund over the same path, and the rest is the fund. UYG aims to return +2 times XLF'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.
Questions people ask
- Which came closer to its stated multiple, SKF or UYG?
- Over the window to Sep 11, 2026, SKF finished 2.9 points from what its multiple implies and UYG finished 1.6 points from its own, so UYG came closer. Neither figure predicts the next window: it depends on how much the underlying moves about.
- Are SKF and UYG levered on the same thing?
- Yes. Both are levered on financials, SKF at -2 times and UYG at +2 times the daily move.
- Which one decays faster, SKF or UYG?
- Decay follows how much the underlying moves about. Over this window SKF’s moved at 13% annualized and UYG’s at 13%, so SKF has the rougher ride and, at the same multiple, loses more to compounding.
- Can I hold SKF or UYG 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, SKF or UYG?
- SKF charges 0.95% a year and UYG charges 0.94%, so UYG is cheaper. Fees come from each fund's prospectus.
