### Method

The daily miss is AMZG's return each day less two times AMZN'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 21 of the 63 sessions. AMZG ranks 135 of 494 2x leveraged ETFs on its 90-day average daily miss. Up days and down days split the miss by whether AMZN 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. 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 AMZG is listed.
