Some of us do our own homework: 10. Where can I find threshold lists?
Threshold securities are included on a list disseminated by an SRO. If a threshold security is listed on more than one market system, the SROs have agreed that the security will appear only on the threshold list of the SRO that maintains the primary listing. FINRA publishes a list of OTC threshold securities. You can obtain SRO threshold lists at the following websites:
Other national securities exchanges that are not the primary listing exchange for any securities at this time are currently not publishing threshold securities lists. https://www.sec.gov/investor/pubs/regsho.htm
As you can see, public information on a pinky stop sign is very limited. That's why we use alternative sources like phone calls begging to buy back shares....
