Short positions

Aggregate short positions in this listing as reported to CIRO, as of the 15th and the last day of each month and published a few days later. Capture began with the reports CIRO still served at its first read, about a year back, and grows twice a month. Net change is CIRO's change from its previous report. Average daily volume and days to cover come from this listing's own daily volume over the trading days since the previous as-of date, and are blank when no volume is held for that period.
