Publish Schedule

FINRA Rule 4560 requires FINRA member firms to report their short positions in equity securities to FINRA twice a month. All short interest positions must be reported by 6 p.m. Eastern Time on the second business day after the reporting settlement date designated by FINRA.

The mid-month short interest report is based on short positions held by members on the settlement date of the 15th of each month. If the 15th falls on a weekend or another non-settlement date, the designated settlement date will be the previous business day on which transactions settled.

The end-of-month short interest report is based on short positions held on the last business day of the month on which transactions settle. Once the short position reports are received, the short interest data is compiled for each security and provided for publication on the 7th business day after the reporting settlement date.

AmendmentsOccasionally there is a need to update the data. When those corrections are made, a Revision Flag will appear next to the revised item. Only the most recent data is made available.
