The Short Sale Trading Statistics Summary Report prepared by IIROC shows the aggregate proportion of short selling in the total trading activity of a particular security, based on data for trades marked “short sale” supplied to IIROC by each marketplace monitored by IIROC. The report is produced twice monthly: (i) for the period from the first to the 15th of each month, and (ii) for the 16th to the end of each month.
The report is based on the total aggregate trading on all marketplaces during the reporting period and shows the actual number, value, and volume of short sales of each listed security and as a percentage of total trading activity for the security.
The reports are provided in CSV (comma separated value) file format which can be imported into most spreadsheet and database programs. Column widths showing ###### may have to be increased to fully display the data.
For more information on the definition of a “short sale” and those orders that must carry the “short sale” designation, see IIROC Notice 12-0300.
Short Sale Trading Corrections Report
Trade marker corrections affecting short sale traded volume entered during the reporting period through IIROC’s Regulatory Marker Correction System (RMCS) are in the Short Sale Trading Corrections Report.
Corrections are aggregated by security for corrections to trades that occurred in a particular reporting period as indicated on the report. Users may wish to use the information in the Short Sale Trading Correction Report to recalculate values recorded in the Short Sale Trading Summary Report.
Consolidated Short Position Report
This report shows the aggregate short positions of all listed and quoted securities based on data submitted to IIROC. We produce this report as of the 15th and the last day of each month.
The report indicates the security name, symbol, listing exchange, the aggregate number of shares short, and the net change in the number of shares short measured against the prior report of each listed or quoted security.
The reports are provided in XLS (Excel) file format and can be imported into most spreadsheet and database programs.
For more information on short position calculation and reporting, see IIROC Notices 17-0241 and 18-0062 and the user guide (pdf).
