DUG's largest daily misses
The 5 days DUG 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 | Energy moved | Target | DUG returned | Miss |
|---|---|---|---|---|---|---|
| 1 | Nov 4, 2026 | closing price | −4.74% | +9.48% | +9.79% | +0.31 pts |
| 2 | Sep 11, 2026 | NAV | +0.32% | −0.65% | −0.49% | +0.15 pts |
| 3 | Oct 5, 2026 | closing price | +1.00% | −2.01% | −1.88% | +0.12 pts |
| 4 | Oct 27, 2026 | NAV | −2.00% | +3.99% | +4.11% | +0.11 pts |
| 5 | Jul 2, 2026 | NAV | +0.82% | −1.64% | −1.53% | +0.10 pts |
The daily miss is DUG's return each day less minus two times Energy'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. DUG ranks 16 of 75 2x inverse ETFs on its 90-day average daily miss.
The rest of the method
Up days and down days split the miss by whether Energy 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. Energy 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 DUG is listed.
