From the Browser report blog about the OTC market tiers:
The OTCQX market (The Intelligent Market) is the top-tier marketplace. Companies in this tier exhibit the high quality financial standards and have their information readily available.
The OTCQB market (The Venture Market) is the middle-tier marketplace. Companies in this tier are not held to certain financial standards, but they are current in their financial reporting.
The OTCPink market is the bottom-tier marketplace. Companies in this tier are the riskiest as deemed by OTC Markets. The companies are broken up into three categories: Pink Current Information, Pink Limited Information, and Pink No Information. The divisions are pretty self-explanatory, each based on the availability of the company’s financial information.
What do these divisions do?
In short, these tiers provide a higher level of transparency leading to an increase in investor confidence. By screening each stock in the marketplace, OTC Markets is able to pin point those stocks that stand out, and those that require scrutiny. By doing so, investors are able to better decide which companies are worthy of investment, which companies could be infrequently trading/reporting, and which are shell companies.
