OTC (Over-the-Counter) Trading

OTC (Over-the-Counter) trading refers to buying and selling financial instruments directly between parties, rather than through a centralized exchange. It’s commonly used for small-cap stocks, bonds, derivatives, and specialized assets.
background

OTC trading takes place outside traditional exchanges like NYSE or NASDAQ. Instead of going through a centralized marketplace with standardized rules and public order books, trades happen through broker-dealer networks. These firms negotiate prices directly with buyers and sellers, creating a more flexible but less transparent environment.

Many assets trade OTC because they don’t meet exchange listing requirements or because they’re too specialized for exchange trading. Examples include certain corporate bonds, derivatives, foreign currencies, pink-sheet stocks, and emerging-market instruments. OTC markets often support early-stage or small companies that are not yet ready—or eligible—for major exchanges.

While OTC markets offer flexibility and access to niche assets, they also come with higher risks. Liquidity is usually lower, spreads are wider, and pricing information can be less transparent. For investors, this means greater uncertainty around execution and valuation. Still, OTC markets play an important role by giving companies and investors more choices outside traditional exchanges.

OTC trading matters because it expands market access beyond exchange-listed assets, offering flexibility and customized trading. However, it requires caution due to lower transparency and higher liquidity risk.

Exchange trading happens on centralized platforms with transparent order books, standardized rules, and regulated price discovery. OTC trading occurs through broker-dealers negotiating privately, so prices and volumes are not always visible to the public. This structure allows more flexibility but introduces risks around pricing accuracy, liquidity, and counterparty trust.

Certain assets, like complex derivatives, municipal bonds, or small-cap equities, may not fit exchange requirements due to size, structure, or trading volume. OTC markets allow these instruments to trade more freely without strict listing standards. Companies that are too new, too small, or unable to meet regulatory thresholds may also use OTC markets to reach investors.

OTC markets can have low liquidity, wide spreads, and limited pricing transparency, making it harder to execute trades at fair value. There’s also higher counterparty risk because trades depend on the reliability of the broker-dealer. Regulatory oversight may be lighter, and some OTC-listed companies provide limited financial disclosures—making due diligence essential.

A small biotech startup doesn’t meet NASDAQ’s listing requirements, so its shares trade on the OTCQB marketplace. Investors can still buy and sell its stock through broker-dealers, but the spreads are wider, liquidity thinner, and disclosure requirements lower than on major exchanges.
