CAT Reportable Equity Securities Symbol Master

The CAT Reportable Equity Securities Symbol Master is a list of all NMS stocks and CAT-reportable OTC equity securities representing the current trading day. FINRA CAT will publish two files each day, one representing the list of reportable equity securities as of the start of the trading day (SOD) and a second file representing the list of reportable equity securities at the end of the trading day (EOD).

The SOD CAT Reportable Equity Securities Symbol Master will be published by 6 a.m. ET, and the EOD file will be published at by 6 p.m. ET. The EOD file contains any securities added during the trading day. Securities deleted during the trading day are not included in the EOD file. To ensure all securities reportable during any given trading day are identified for reporting, firms are encouraged to use both the SOD and EOD files.
