The OTC Markets topic covers how over-the-counter securities are traded outside of formal exchanges, the role of market makers and broker-dealers, and the regulatory framework that governs these decentralized transactions. For the FINRA SIE Exam, you need to understand how OTC markets function differently from exchanges, the types of securities traded OTC, and the quotation systems used.
The over-the-counter (OTC) market is a decentralized network of broker-dealers who trade securities directly with each other via telephone and computer networks rather than through a centralized exchange floor. Unlike exchanges such as the NYSE or Nasdaq, the OTC market has no physical trading floor and no centralized price discovery mechanism.
OTC markets primarily trade securities that do not meet the listing requirements of major exchanges. These include smaller company stocks, corporate bonds, government securities, and certain derivatives. The market operates through a network of dealers who quote prices at which they will buy (bid) and sell (ask) securities.
Market makers are broker-dealers that hold themselves out as willing to buy and sell specific securities on a regular and continuous basis at publicly quoted prices. They provide liquidity by maintaining an inventory of securities and profiting from the spread between their bid and ask prices.
Key responsibilities and characteristics of market makers:
Broker-dealers may act as either agents (brokers) or principals (dealers) in OTC transactions. When acting as a broker, they execute customer orders and charge a commission. When acting as a dealer, they buy or sell from their own inventory and charge a markup or markdown.
The OTC market uses electronic quotation systems to disseminate pricing information and facilitate trading. OTC Markets Group operates the primary quotation platform for OTC equity securities, organized into three tiers based on the quality and quantity of information companies provide.
OTCQX is the highest tier, featuring established companies that meet higher financial standards and provide current disclosure. Companies on OTCQX must have a qualified third-party advisor (such as an investment bank or law firm) sponsor their listing.
OTCQB is the middle tier, designed for early-stage and developing U.S. and international companies. Companies must be current in their reporting to remain on OTCQB.
Pink Market (formerly Pink Sheets) is the most speculative tier with no minimum financial standards or reporting requirements. Companies here may or may not provide current financial information.

OTC Link ATS (Alternative Trading System) is an electronic interdealer quotation and messaging system operated by OTC Markets Group. It allows broker-dealers to publish quotes, communicate about trades, and report transactions for OTC equity securities.
The OTC market handles a wide range of securities that either don't qualify for exchange listing or whose issuers prefer OTC trading.
Equity securities trading OTC include:
Debt securities comprise the largest volume of OTC trading:
FINRA (Financial Industry Regulatory Authority) is the primary self-regulatory organization overseeing OTC markets. FINRA establishes rules for broker-dealers participating in OTC trading, monitors trading activity, and enforces compliance.
Key regulatory requirements:
The SEC (Securities and Exchange Commission) maintains overall regulatory authority over OTC markets, including:
Understanding the differences between OTC and exchange trading is essential for the exam, as questions frequently test your ability to distinguish between these market structures.

The bid-ask spread is the difference between the highest price a buyer is willing to pay (bid) and the lowest price a seller is willing to accept (ask). In OTC markets, market makers profit from this spread rather than charging commissions.
Example: A market maker quotes a stock at $10.00 bid / $10.25 ask. The spread is $0.25. If they buy at $10.00 and sell at $10.25, they earn $0.25 per share.
FINRA requires broker-dealers to report OTC equity transactions to ensure market transparency and regulatory oversight. Trades must be reported to FINRA's Trade Reporting Facilities (TRFs) within specified timeframes.
1. Scenario: A question asks where most corporate bonds are traded, with options including NYSE, Nasdaq, OTC market, or futures exchanges.
Correct Approach: Select OTC market. The vast majority of corporate bonds trade in the OTC market through dealer networks, not on exchanges, even though some bonds may technically be listed on exchanges.
Check first: The security type-bonds almost always trade OTC regardless of the issuer's stock listing.
Do NOT do first: Assume that if a company's stock is listed on an exchange, its bonds must also trade there. Bond trading is structurally different and occurs OTC.
Why other options are wrong: Exchanges primarily handle equity trading; corporate bonds have always been dealer market instruments where institutional participants negotiate prices directly.
2. Scenario: The exam presents a market maker quoting a stock at $15.50 bid / $15.75 ask and asks what the market maker's profit potential is per share.
Correct Approach: The spread of $0.25 represents the profit potential if the market maker buys at bid and sells at ask. This is how OTC dealers earn compensation.
Check first: Identify that the question is asking about the bid-ask spread, which equals ask price minus bid price.
Do NOT do first: Look for a commission percentage or try to calculate a markup separately from the spread. The spread itself is the dealer's compensation mechanism.
Why other options are wrong: Commission-based answers confuse broker and dealer functions; market makers acting as principals don't charge commissions but instead profit from the spread.
3. Scenario: A question asks which OTC tier has the most stringent disclosure requirements and financial standards.
Correct Approach: OTCQX is the highest tier with the most stringent requirements, including mandatory qualified advisor sponsorship and current disclosure.
Check first: The hierarchy of OTC tiers from highest to lowest standards: OTCQX → OTCQB → Pink Market.
Do NOT do first: Assume Pink Sheets (Pink Market) would have any standards. The Pink Market is the least regulated tier with no mandatory disclosure.
Why other options are wrong: OTCQB has moderate standards but doesn't require advisor sponsorship; Pink Market has essentially no standards or requirements.
4. Scenario: An exam question describes a transaction where a broker-dealer buys securities from a customer for its own inventory and asks how the firm is acting and how it's compensated.
Correct Approach: The firm is acting as a dealer (principal) and earns a markdown when buying from a customer. Dealers trade from inventory and profit from the spread, not commissions.
Check first: Whether the firm is using its own inventory (dealer/principal) or executing an order for the customer without taking ownership (broker/agent).
Do NOT do first: State that the firm charges a commission. Commissions apply to agency transactions; principal transactions involve markups or markdowns.
Why other options are wrong: Broker/agent answers apply when the firm doesn't take ownership; markup applies to sales to customers, not purchases from customers.
5. Scenario: The exam asks which regulatory body has primary oversight of day-to-day OTC market operations and broker-dealer conduct in these markets.
Correct Approach: FINRA is the self-regulatory organization with direct oversight of OTC broker-dealer activities, quote publication, and trade reporting.
Check first: Distinguish between the SEC's overall regulatory authority and FINRA's role as the front-line SRO for broker-dealer supervision.
Do NOT do first: Choose the SEC for operational oversight questions. While the SEC has ultimate authority, FINRA handles day-to-day regulation, examination, and enforcement for broker-dealers.
Why other options are wrong: The SEC oversees the securities industry broadly but delegates broker-dealer supervision to FINRA; exchanges regulate their own members, not OTC participants.
Task: Calculating the effective cost to a customer in an OTC transaction involving dealer markup
Example: A dealer buys a security at $20.00 and applies a 5% markup when selling to a customer.
Markup amount: \( 20.00 × 0.05 = 1.00 \)
Customer price: \( 20.00 + 1.00 = 21.00 \)
The customer pays $21.00 total with no additional charges.
Task: Determining which OTC tier is appropriate for a company based on its characteristics
Q1: Where do most corporate bonds trade?
(a) New York Stock Exchange
(b) Over-the-counter market
(c) Nasdaq Stock Market
(d) Chicago Board Options Exchange
Ans: (b)
Most corporate bonds trade in the over-the-counter market through dealer networks, not on exchanges. Even bonds that are technically listed on exchanges conduct the vast majority of their trading activity OTC. Options (a) and (c) are equity exchanges where bonds rarely trade; option (d) is an options exchange, not a bond trading venue.
Q2: A market maker displays a quote of $22.00 bid / $22.50 ask for a stock. What does this indicate?
(a) The market maker will buy at $22.50 and sell at $22.00
(b) The market maker will buy at $22.00 and sell at $22.50
(c) The market maker charges a $0.50 commission per share
(d) Customers must pay $22.00 to purchase shares
Ans: (b)
The bid is the price at which the market maker will buy ($22.00), and the ask is the price at which they will sell ($22.50). Option (a) reverses bid and ask incorrectly. Option (c) confuses markup/markdown with commissions-market makers don't charge commissions but profit from the spread. Option (d) states the wrong price; customers buying pay the ask price ($22.50), not the bid.
Q3: Which OTC market tier requires companies to have a qualified third-party advisor sponsor their listing?
(a) Pink Market
(b) OTCQB
(c) OTCQX
(d) All OTC tiers require sponsorship
Ans: (c)
OTCQX, the highest tier, requires companies to have a qualified third-party advisor (such as an investment bank or law firm) sponsor their listing. OTCQB and Pink Market do not have this requirement. Option (b) applies to the middle tier without sponsorship requirements; option (a) has no standards at all; option (d) is incorrect because only OTCQX requires sponsorship.
Q4: A broker-dealer buys 500 shares from a customer for its own account at $18.00 per share when the current market price is $18.50. The firm is acting as a:
(a) Broker and will charge a commission
(b) Dealer and will earn a markup
(c) Dealer and will earn a markdown
(d) Agent and will earn a spread
Ans: (c)
When a broker-dealer buys securities for its own account (inventory), it's acting as a dealer/principal. When purchasing from a customer, the dealer applies a markdown-buying below current market price. Option (a) is wrong because brokers don't buy for their own account. Option (b) uses the wrong term; markup applies when selling to customers, not buying from them. Option (d) is incorrect because agents don't take positions and earn commissions, not spreads.
Q5: Which regulatory organization has primary day-to-day oversight of broker-dealers participating in OTC markets?
(a) Securities and Exchange Commission (SEC)
(b) Financial Industry Regulatory Authority (FINRA)
(c) Municipal Securities Rulemaking Board (MSRB)
(d) Federal Reserve Board
Ans: (b)
FINRA is the self-regulatory organization with direct day-to-day oversight of broker-dealers, including their OTC market activities, quote publication, and trade reporting. While the SEC has overall regulatory authority (option a), FINRA handles operational supervision. Option (c) regulates municipal securities specifically, not general OTC markets. Option (d) regulates banks and monetary policy, not securities broker-dealers.
Q6: A company in bankruptcy proceedings with no current public financial disclosures would most likely trade on which OTC tier?
(a) OTCQX
(b) OTCQB
(c) Pink Market
(d) The company cannot trade OTC during bankruptcy
Ans: (c)
Companies in bankruptcy are explicitly excluded from OTCQX and OTCQB but can trade on the Pink Market, which has no financial standards or disclosure requirements. Options (a) and (b) prohibit bankrupt companies. Option (d) is incorrect because bankrupt companies can continue trading on the Pink Market, though at high risk to investors.
