SDS in plain words

Three months to Sep 30, 2026: SDS returned −3.2% where its own daily promise gave −5.7%, 2.5 points over. Read the multiple against the whole window instead and −2 times SPY's 2.5% implies −5.0%, 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 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.

SPDN in plain words

Three months to Sep 30, 2026: SPDN returned −1.1% where its own daily promise gave −2.8%, 1.7 points over. Read the multiple against the whole window instead and −1 times SPY's 2.5% implies −2.5%, which makes SPDN look 1.4 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 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.

Questions people ask

Which came closer to its stated multiple, SDS or SPDN?
Over the window to Sep 30, 2026, SDS finished 1.8 points from what its multiple implies and SPDN finished 1.4 points from its own, so SPDN came closer. Neither figure predicts the next window: it depends on how much the underlying moves about.
Are SDS and SPDN levered on the same thing?
Yes. Both are levered on the S&P 500, SDS at -2 times and SPDN at -1 times the daily move.
Which one decays faster, SDS or SPDN?
Decay follows how much the underlying moves about. Over this window SDS’s moved at 11% annualized and SPDN’s at 11%, so SDS has the rougher ride and, at the same multiple, loses more to compounding.
Can I hold SDS or SPDN 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 SPDN?
SDS charges 0.91% a year and SPDN charges 0.48%, so SPDN is cheaper. Fees come from each fund's prospectus.
