The daily miss is UCO's return each day less two times Bloomberg Crude Oil'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 its NAV or its target's is not struck at the 4:00 p.m. close. UCO ranks 130 of 494 2x leveraged ETFs on its 90-day average daily miss.
The rest of the method
Up days and down days split the miss by whether Bloomberg Crude Oil 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. Bloomberg Crude Oil 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 UCO is listed.
