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. SDS ranks 1 of 75 2x inverse ETFs on its 90-day average daily miss. Up days and down days split the miss by whether S&P500 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. S&P500 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 SDS is listed.\n Where to next\n SDS fund page 2x inverse ETFs ranked by daily tracking Leveraged ETF tracking by issuer How daily tracking is measured The tracking data file Sources\n The multiple each fund states in its own registered name, from the SEC investment company series and class file SEC EDGAR, full-text search of fund filings SEC Form N-PORT, what a fund filed it holds Rule 19a-1, what a distribution notice must say Links are sources, not endorsements.\n A ranking is not a recommendation or an opinion.
