UWTI: 3x leveraged exposure to WTI
DWTI: 3x leveraged inverse exposure to WTI
The inverse relationship between these two symbols seems to trend toward the origin on a log-log plot (using log base 2). I'm plotting only intervals of large movement, so not all days are shown. Green intervals are ones where UWTI goes up. Red intervals are ones where DWTI goes down.
Question: Why do green and red intervals have consistently different slopes that make the overall trend toward the origin (see blue arrow)?
Note: Large movement was determined visually, from the bottom to the top (or vice versa) of intervals of significant price change. The days that are not represented at all in this graph had no visually significant movement. Graph is based on daily close prices.
