SDS in plain words
Three months to Sep 11, 2026: SDS returned −4.8% where its own daily promise gave −7.3%, 2.5 points over. Read the multiple against the whole window instead and −2 times SPY's 3.3% implies −6.6%, which makes SDS look 1.8 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. SDS aims to return -2 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 -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. 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.
SPXS in plain words
Three months to Sep 11, 2026: SPXS 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 SPXS 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. SPXS 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, SDS or SPXS?
- Over the window to Sep 11, 2026, SDS finished 1.8 points from what its multiple implies and SPXS finished 2.0 points from its own, so SDS came closer. Neither figure predicts the next window: it depends on how much the underlying moves about.
- Are SDS and SPXS levered on the same thing?
- Yes. Both are levered on the S&P 500, SDS at -2 times and SPXS at -3 times the daily move.
- Which one decays faster, SDS or SPXS?
- Decay follows how much the underlying moves about. Over this window SDS’s moved at 12% annualized and SPXS’s at 12%, so SDS has the rougher ride and, at the same multiple, loses more to compounding.
- Can I hold SDS or SPXS 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, SDS or SPXS?
- SDS charges 0.91% a year and SPXS charges 1.04%, so SDS is cheaper. Fees come from each fund's prospectus.
