SSO in plain words
Three months to Sep 11, 2026: SSO returned +4.9% where its own daily promise gave +6.3%, 1.4 points short. Read the multiple against the whole window instead and +2 times SPY's 3.3% implies +6.6%, 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 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.
UPRO in plain words
Three months to Sep 11, 2026: UPRO returned +6.4% where its own daily promise gave +9.0%, 2.6 points short. Read the multiple against the whole window instead and +3 times SPY's 3.3% implies +9.9%, which makes UPRO look 3.5 points short. 0.9 of that is daily compounding, which happens to any +3 times fund over the same path, and the rest is the fund. UPRO 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, SSO or UPRO?
- Over the window to Sep 11, 2026, SSO finished 1.7 points from what its multiple implies and UPRO finished 3.5 points from its own, so SSO came closer. Neither figure predicts the next window: it depends on how much the underlying moves about.
- Are SSO and UPRO levered on the same thing?
- Yes. Both are levered on the S&P 500, SSO at +2 times and UPRO at +3 times the daily move.
- Which one decays faster, SSO or UPRO?
- Decay follows how much the underlying moves about. Over this window SSO’s moved at 12% annualized and UPRO’s at 12%, so SSO has the rougher ride and, at the same multiple, loses more to compounding.
- Can I hold SSO or UPRO 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, SSO or UPRO?
- SSO charges 0.87% a year and UPRO charges 0.89%, so SSO is cheaper. Fees come from each fund's prospectus.
