OTC
Our Open, Transparent and Connected financial marketplaces provide investors with the information necessary to intelligently analyze, value and trade 10,000 U.S. and global securities through the broker of their choice.
To create clarity in the investment process, we organize these securities into three tiered marketplaces - OTCQX, OTCQB and OTC Pink - based on the quality and quantity of information the companies make available.
The Best Marketplace with Qualified Companies
The OTCQX® marketplace offers the best informed and most efficient trading for U.S. and global companies. To qualify for the OTCQX marketplace, companies must meet high financial standards, be current in their disclosure, and be sponsored by a professional third-party advisor . Designed for the most reputable, liquid and investor-friendly companies, OTCQX ensures that investors have the information necessary to intelligently analyze, value and trade their securities.
The Venture Stage Marketplace with Reporting Companies
The OTCQB® marketplace offers informed trading for securities for smaller or developing companies that are reporting to a U.S. regulator (SEC, Bank, or Insurance). Since OTCQB has no minimum financial standards, it includes shells and penny stocks that are current in their disclosure to regulators.
The OTCQB marketplace has effectively replaced the FINRA operated OTC Bulletin Board (OTCBB) as the primary market for SEC and bank reporting securities that trade off the exchanges.
The Open Marketplace with Variable Reporting Companies
The OTC Pink® marketplace offers trading in a wide spectrum of equity securities through any broker. This marketplace is for all types of companies that are there by reasons of default, distress or design, which is why they are further sub-categorized by the levels of information that they provide.
