Here you'll find quick answers to common questions about over the counter trading.
Over-the-counter (OTC) trading, also known as off-exchange trading, occurs in the OTC market. Unlike traditional exchanges, the OTC market does not have a physical location or a set group of members and is not regulated by a securities exchange. Instead, trades are conducted through a network of brokers, and the prices are not always publicly disclosed.
The OTC market includes approximately 10,000 different types of securities, such as large American Depositary Receipts (ADRs), foreign ordinary shares, and stocks of small and micro-cap growth companies. Some OTC securities report to the U.S. Securities and Exchange Commission (SEC), while others may follow different reporting standards or not report at all.
Securities listed on regulated exchanges must adhere to stringent listing requirements, and issuers must fulfill comprehensive disclosure obligations. These regulations can impose significant costs on smaller or startup companies. Non-listed securities are not inherently inferior; they simply may not have applied for exchange listing due to various strategic reasons. In the U.S., for instance, newly issued federal securities, municipal bonds, and corporate bonds can all be traded OTC.
(Please note: Investing in OTC securities carries higher risks compared to on-exchange trading. Investors should understand the risks and background of the securities before investing.)
Pros
Cons
OTC Markets Group employs a three-tiered system based on the quality and quantity of information disclosed about OTC products. This system does not indicate the stock's quality or risk but serves as a guide for investors to exercise caution before investing. The tiers are as follows:
OTCQX is the top tier of the three marketplaces. Companies in this tier must provide timely and comprehensive disclosure of regulatory information, maintain audited financial statements, and are not classified as penny stocks, shell companies, or bankrupt entities. Certain exceptions apply, such as certain foreign companies that issue American Depositary Receipts (ADRs) in the U.S., which may also fall under the OTCQX category.
The middle tier is called OTCQB, which consists of early-stage and developing companies. Companies in this tier must have a minimum bid price of USD 0.01 and provide up-to-date regulatory reports. They must also have their annual financials reviewed according to U.S. Generally Accepted Accounting Principles (GAAP) and must not be in bankruptcy.
The Pink Market is an open market that imposes no minimum financial standards and encompasses a diverse range of companies, including foreign entities, penny stocks, shell companies, and others that opt not to disclose financial information. These companies often have smaller scales and uncertain growth prospects.
