SSO's largest daily misses
The 5 days SSO strayed furthest from its daily target in the 1 year to Nov 4, 2026, each on its NAV where ETFIQ holds it, else its closing price.
| # | Day | Read on | S&P500 moved | Target | SSO returned | Miss |
|---|---|---|---|---|---|---|
| 1 | Jun 26, 2026 | NAV | −0.05% | −0.09% | −0.38% | −0.29 pts |
| 2 | Jun 29, 2026 | NAV | +1.18% | +2.35% | +2.50% | +0.15 pts |
| 3 | Jul 2, 2026 | NAV | 0.00% | +0.01% | −0.11% | −0.12 pts |
| 4 | Apr 2, 2026 | NAV | +0.12% | +0.24% | +0.17% | −0.07 pts |
| 5 | Nov 7, 2025 | NAV | +0.14% | +0.27% | +0.21% | −0.06 pts |
The daily miss is SSO's return each day less two times S&P500's return that day. A basis point is a hundredth of a percentage point. Each window is read twice where ETFIQ holds both NAVs: on NAVs, and on closing prices. SSO ranks 1 of 494 2x leveraged ETFs on its 90-day average daily miss.
The rest of the method
Up days and down days split the miss by whether S&P500 rose or fell; Significant means the gap is at least two standard errors from zero. The average miss carries its sign: a negative one is what the fund kept below its target each day, its fees and financing among it. S&P500 is itself an ETF, so its own fee and tracking are inside the miss. Not every fund here has traded for a year, and a number over eight months does not order against one over twelve. This page lists each fund with its window and dates instead of ranking them. It becomes a ranking on the night four of them share a full year. Every window ETFIQ can measure for SSO is listed.
