SPXU's largest daily misses
The 5 days SPXU 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 | SPXU returned | Miss |
|---|---|---|---|---|---|---|
| 1 | Jul 2, 2026 | NAV | 0.00% | −0.01% | +0.19% | +0.20 pts |
| 2 | Sep 4, 2026 | NAV | −0.36% | +1.08% | +1.26% | +0.18 pts |
| 3 | Oct 9, 2026 | NAV | +0.60% | −1.81% | −1.65% | +0.17 pts |
| 4 | May 22, 2026 | NAV | +0.38% | −1.13% | −0.97% | +0.16 pts |
| 5 | Jan 16, 2026 | NAV | −0.06% | +0.17% | +0.33% | +0.15 pts |
The daily miss is SPXU's return each day less minus three 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. SPXU ranks 3 of 19 3x inverse 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 SPXU is listed.
