SH in plain words

Three months to Sep 30, 2026: SH 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 SH 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. SH 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 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.

SSO in plain words

Three months to Sep 30, 2026: SSO returned +3.3% where its own daily promise gave +4.8%, 1.4 points short. Read the multiple against the whole window instead and 2 times SPY's 2.5% implies +5.0%, which makes SSO look 1.7 points short. 0.3 of that is daily compounding, which happens to any 2 times fund over the same path, and the rest is the fund. SSO aims to return +2 times SPY'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, SH or SSO?
Over the window to Sep 30, 2026, SH finished 1.5 points from what its multiple implies and SSO finished 1.7 points from its own, so SH came closer. Neither figure predicts the next window: it depends on how much the underlying moves about.
Are SH and SSO levered on the same thing?
Yes. Both are levered on the S&P 500, SH at -1 times and SSO at +2 times the daily move.
Which one decays faster, SH or SSO?
Decay follows how much the underlying moves about. Over this window SH’s moved at 11% annualized and SSO’s at 11%, so SH has the rougher ride and, at the same multiple, loses more to compounding.
Can I hold SH or SSO 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, SH or SSO?
SH charges 0.88% a year and SSO charges 0.84%, so SSO is cheaper. Fees come from each fund's prospectus.
