MYY's largest daily misses
The 5 days MYY 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 | MidCap400 moved | Target | MYY returned | Miss |
|---|---|---|---|---|---|---|
| 1 | Oct 5, 2026 | closing price | +0.39% | −0.39% | −0.23% | +0.16 pts |
| 2 | Oct 16, 2026 | NAV | −0.89% | +0.89% | +0.97% | +0.08 pts |
| 3 | Jun 26, 2026 | NAV | −0.15% | +0.15% | +0.21% | +0.06 pts |
| 4 | Sep 11, 2026 | NAV | +0.84% | −0.84% | −0.78% | +0.06 pts |
| 5 | Nov 17, 2025 | NAV | −1.81% | +1.81% | +1.85% | +0.05 pts |
The daily miss is MYY's return each day less minus one times MidCap400'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. MYY ranks 6 of 34 1x inverse ETFs on its 90-day average daily miss.
The rest of the method
Up days and down days split the miss by whether MidCap400 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. MidCap400 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 MYY is listed.
