OTC securities are stocks, bonds, and other financial instruments that trade through a network of broker-dealers instead of on a centralized exchange like the New York Stock Exchange or Nasdaq. The market covers small-company shares, foreign issuers, most corporate and municipal bonds, and many derivative contracts. Because companies quoted over-the-counter face lighter listing standards and often disclose less financial information, these investments carry risks that exchange-listed securities usually do not.
How OTC Trading Works
On a traditional exchange, a central system matches buy and sell orders and shows one price at a time. Over-the-counter, individual broker-dealers called market makers hold their own inventory and post the prices they will buy at (the bid) and sell at (the ask). When you place an order, your broker routes it to one of these dealers instead of to an exchange’s matching engine.
The SEC describes OTC Link, one of the main electronic quotation platforms, as a system where market makers and other broker-dealers publish bid and ask prices for OTC securities.1U.S. Securities and Exchange Commission. OTC Link LLC Because no single specialist sets the price, the same security can be quoted at slightly different prices by different dealers at the same moment. The dealer on the other side of your trade may be selling from its own inventory or buying for its own account rather than matching you with another customer.
Your broker owes you best execution under FINRA Rule 5310, meaning it must use reasonable diligence to find the most favorable terms available for your order. The obligation is especially demanding for OTC securities with limited quotations, and firms must maintain written policies explaining how they identify the best market for thinly traded stocks.2FINRA. 5310 – Best Execution and Interpositioning
Trading costs typically include a commission, a markup when a dealer sells to you from inventory above what it paid, or a markdown when it buys from you below what it plans to resell. These charges do not always appear as a separate line item, so it is worth asking your broker how it is compensated on OTC trades. Most OTC equity transactions now settle on a T+1 basis, meaning one business day after execution. The SEC adopted that standard in 2024 under amendments to Rule 15c6-1, with a limited exemption for securities whose transfer or delivery facilities are primarily located outside the United States.3U.S. Securities and Exchange Commission.

What Trades Over-the-Counter
Stocks and ADRs
The OTC market hosts shares of companies that do not meet, or choose not to pursue, the listing standards of a national exchange. These include small startups, early-stage businesses, and foreign issuers. Foreign companies often participate through American Depositary Receipts, certificates representing ownership interests in foreign securities held by a domestic bank.4U.S. Securities and Exchange Commission. Additional Form F-6 Eligibility Requirement Related to the Listed Status of Deposited Securities Underlying American Depositary Receipts ADRs let you invest in a foreign company and receive dividends in U.S. dollars without buying shares on a foreign exchange.
Bonds and Derivatives
Most bond trading happens over-the-counter. Corporate bonds, municipal bonds, and government agency debt all move through dealer networks because the variety of fixed-income products, each with different maturities, coupon rates, and credit qualities, makes centralized listing impractical. Institutional investors trade these instruments in large blocks directly with dealers or with each other. The OTC structure also accommodates customized derivative contracts and private placements whose terms do not fit a standardized exchange format.
OTC Market Tiers and What They Tell You
OTC Markets Group, which operates OTC Link, sorts securities into tiers based on how much financial information the issuing company discloses. Checking a stock’s tier is the fastest way to gauge how transparent an issuer is before you invest.
OTCQX Best Market
OTCQX is the top tier and is designed for established companies that meet financial and governance standards. To qualify, a company cannot be in bankruptcy or reorganization, and it must hold annual shareholders’ meetings with financial reports made available at least 15 calendar days beforehand.5OTC Markets. OTCQX Rules for US Companies Shell companies and penny stocks are excluded. Companies here often want a public market for their shares but choose not to list on a national exchange because of the higher costs and regulatory burden.
OTCQB Venture Market
OTCQB is aimed at earlier-stage growth companies. An issuer must maintain a minimum closing bid price of at least $0.01 per share for 30 consecutive calendar days before applying, stay current in its financial reporting, and file an annual certification signed by the CEO or CFO. A company that drops below the minimum bid price gets a 90-calendar-day grace period to regain compliance before being removed.6OTC Markets Group Inc. OTCQB Standards
Pink Open Market
The Pink Open Market has the fewest barriers to entry. It includes companies that may be in financial distress, that provide only limited financial information, or that choose not to disclose anything at all. Securities on this tier are classified by how much data the company makes available, ranging from Current Information (the company publishes regular financial reports) down to No Information (the company provides nothing). The label lets you see at a glance how much you can learn about a company before putting money into its stock.
The Expert Market
Below Pink sits the Expert Market, a restricted tier for securities that fail to meet even minimal disclosure standards. When a company becomes delinquent in its SEC filings, its shares can be moved there with no grace period. Shell companies that stop making information publicly available land here as well.7OTC Markets. 15c2-11 Resource Center
The consequence for a retail investor is significant. Quotations on the Expert Market are limited to unsolicited orders only, and access is restricted to broker-dealers, institutional investors, and other sophisticated participants.7OTC Markets. 15c2-11 Resource Center If a stock you own gets moved here, you can usually still sell your existing shares through a broker, but you will not see public price quotes, and finding a buyer may be difficult.
Rules That Shape the OTC Market
Two bodies share primary responsibility for the OTC market. The SEC writes and enforces federal securities rules. FINRA, a self-regulatory organization, monitors broker-dealer conduct and market activity day to day.8FINRA. How We Operate
SEC Rule 15c2-11
Rule 15c2-11 is the main gatekeeping rule. Before a broker-dealer can publish a price quote for an OTC security, it must review specific financial information about the issuing company, including recent financial statements, and have a reasonable basis for believing that information is accurate and from reliable sources.9U.S. Securities and Exchange Commission. Publication or Submission of Quotations Without Specified Information
Amendments effective in 2021 tightened the piggyback exception, which had previously allowed dealers to quote a security based only on the fact that other dealers were already quoting it. Under the amended rule, issuers whose required financial information is no longer current lose piggyback eligibility after a 15-calendar-day grace period, and dealers must stop publishing quotes unless they independently verify the issuer’s information.10Federal Register. Publication or Submission of Quotations Without Specified Information This is the mechanism that drives securities into the Expert Market when companies stop filing.
Penny Stock Disclosures
Many OTC securities fall under the federal definition of a penny stock, which generally covers any equity security priced below $5 per share that is not listed on a national exchange or Nasdaq.11GovInfo. Securities and Exchange Commission Rule 240.3a51-1 Exemptions exist for securities with certain minimum net tangible assets, average trading volumes, or bid prices above $50 per share, but most small OTC stocks do not meet those thresholds.
When a security qualifies as a penny stock, your broker must provide extra disclosures before completing the trade: a risk disclosure document, current bid and ask quotations, and information about the compensation the broker receives. These requirements exist because penny stocks are thinly traded, often lack publicly available financial data, and are disproportionately targeted by fraudsters.
The Risks You Actually Take
Thin or Missing Information
Many OTC issuers do not file periodic financial reports with the SEC or provide audited financial statements. The SEC warns that this makes it very difficult for investors to find current, reliable information about these companies, and that OTC-quoted securities can be among the most risky investments available.1U.S. Securities and Exchange Commission. OTC Link LLC Before buying, check the disclosure tier and read whatever financial data the company has published.
Low Liquidity and Wide Spreads
Many OTC securities trade in very low volumes, meaning there may be few buyers when you want to sell. Low liquidity tends to produce wide bid-ask spreads, the gap between what a dealer will pay you and what it charges the next buyer. For smaller trades, those spreads can eat significantly into returns. If a stock gets moved to the Expert Market, liquidity can dry up almost entirely because retail quotations are no longer published.
Pump-and-Dump Schemes
The SEC identifies OTC stocks as among the securities most susceptible to manipulation, particularly through pump-and-dump schemes.12U.S. Securities and Exchange Commission. Pump and Dump Schemes Promoters use false or exaggerated claims through emails, newsletters, social media, or cold calls to drive up the price of a thinly traded stock, then sell their own shares at the inflated price. The stock collapses once the promotion stops, and later buyers suffer steep losses.
Red flags include unsolicited tips about a stock you have never researched, promises of quick guaranteed returns, high-pressure tactics urging you to buy immediately, and claims tied to trending news stories.12U.S. Securities and Exchange Commission. Pump and Dump Schemes The SEC advises independently verifying any claim a promoter makes about a company’s products, contracts, or financial health before investing.
Taxes on OTC Trades
Gains and losses from selling OTC securities are reported on your federal return like any other investment. Your broker issues a Form 1099-B showing the proceeds from each sale. Whether the broker also reports your cost basis depends on how the security is classified. Stocks acquired for cash after 2010 are generally treated as covered securities, and the broker must report cost basis to the IRS. Older shares or certain noncovered securities may have no broker-reported basis, and you are responsible for tracking and reporting it yourself.13Internal Revenue Service. Instructions for Form 1099-B
The wash sale rule applies to OTC stocks too. If you sell one at a loss and buy the same or a substantially identical security within 30 days before or after the sale, the IRS disallows the loss for that tax year. The disallowed loss gets added to the cost basis of the replacement shares instead.14Internal Revenue Service. Application of Wash Sale Rules – Notice 2013-48 The rule can catch you off guard if you try to harvest a loss on an OTC stock and then quickly rebuild the position.
