### Method

The daily miss is EUVX's return each day less two times Corgi Lithography & Semiconductor Photonics ETF'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. It is stated on the closing price because NAVs for 20 of the 63 sessions. EUVX ranks 221 of 494 2x leveraged ETFs on its 90-day average daily miss. Up days and down days split the miss by whether Corgi Lithography & Semiconductor Photonics ETF 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. Corgi Lithography & Semiconductor Photonics ETF is itself an ETF, so its own fee and tracking are inside the miss.
