SPDN in plain words
Three months to Sep 11, 2026: SPDN returned −1.8% where its own daily promise gave −3.5%, 1.7 points over. Read the multiple against the whole window instead and −1 times SPY's 3.3% implies −3.3%, which makes SPDN look 1.5 points over. 0.2 of that is daily compounding, which happens to any −1 times fund over the same path, and the rest is the fund. SPDN aims to return -1 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 -1 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 12% 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.
SPXU in plain words
Three months to Sep 11, 2026: SPXU returned −7.9% where its own daily promise gave −11.3%, 3.4 points over. Read the multiple against the whole window instead and −3 times SPY's 3.3% implies −9.9%, which makes SPXU look 2.0 points over. 1.4 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 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.
Questions people ask
- Which came closer to its stated multiple, SPDN or SPXU?
- Over the window to Sep 11, 2026, SPDN finished 1.5 points from what its multiple implies and SPXU finished 2.0 points from its own, so SPDN came closer. Neither figure predicts the next window: it depends on how much the underlying moves about.
- Are SPDN and SPXU levered on the same thing?
- Yes. Both are levered on the S&P 500, SPDN at -1 times and SPXU at -3 times the daily move.
- Which one decays faster, SPDN or SPXU?
- Decay follows how much the underlying moves about. Over this window SPDN’s moved at 12% annualized and SPXU’s at 12%, so SPDN has the rougher ride and, at the same multiple, loses more to compounding.
- Can I hold SPDN or SPXU 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.
