SPXU in plain words
Three months to Sep 30, 2026: SPXU returned −5.4% where its own daily promise gave −8.9%, 3.4 points over. Read the multiple against the whole window instead and −3 times SPY's 2.5% implies −7.6%, which makes SPXU look 2.1 points over. 1.3 of that is daily compounding, which happens to any −3 times fund over the same path, and the rest is the fund. SPXU aims to return -3 times SPY's move each day, then resets. Over one day it does that. Over longer, the daily results compound, so the total is not -3 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. SPY moved at 11% 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.
SPYU in plain words
Three months to Sep 30, 2026: SPYU returned +1.6% where its own daily promise gave +8.5%, 6.9 points short. Read the multiple against the whole window instead and 4 times SPY's 2.5% implies +10.1%, which makes SPYU look 8.5 points short. 1.6 of that is daily compounding, which happens to any 4 times fund over the same path, and the rest is the fund. SPYU aims to return +4 times SPY's move each day, then resets. Over longer, the daily results compound, so the total is not +4 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, SPXU or SPYU?
- Over the window to Sep 30, 2026, SPXU finished 2.1 points from what its multiple implies and SPYU finished 8.5 points from its own, so SPXU came closer. Neither figure predicts the next window: it depends on how much the underlying moves about.
- Are SPXU and SPYU levered on the same thing?
- Yes. Both are levered on the S&P 500, SPXU at -3 times and SPYU at +4 times the daily move.
- Which one decays faster, SPXU or SPYU?
- Decay follows how much the underlying moves about. Over this window SPXU’s moved at 11% annualized and SPYU’s at 11%, so SPXU has the rougher ride and, at the same multiple, loses more to compounding.
- Can I hold SPXU or SPYU 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.
