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. Short traded volume is the shares sold short on every marketplace CIRO monitors over the period ending on that date, with its percentage of all shares traded there, with CIRO's later corrections to short volume applied. Both are blank when the report for that period is not held or states no short sale in this listing.
