Exchanges Where U.S. Penny Stocks are Commonly Found

Penny stocks don’t live where most investors think they do. 

While the average retail trader pictures the New York Stock Exchange floor or NASDAQ’s electronic boards, the vast majority of U.S. penny stocks under $1 never trade on those venues. 

They trade in a parallel universe of dealer networks, loosely regulated platforms, and tiered markets that operate under dramatically different rules than the exchanges that broadcast CNBC’s opening bell each morning.

Over-the-Counter (OTC) Markets: Primary Home for Penny Stocks

The over-the-counter market represents the dominant trading venue for penny stocks, functioning fundamentally differently from the major exchanges most investors envision when they think about stock trading. 

Rather than matching buyers and sellers through a centralized electronic system or physical trading floor, OTC markets operate through dealer networks where securities firms quote prices directly to each other and to retail investors.

What “Over-the-Counter” Actually Means

The term describes trading that happens directly between parties rather than through a centralized exchange. 

When a Florida investor buys an OTC penny stock, they’re typically purchasing from a dealer’s inventory rather than from another retail investor via an order-matching system. This creates a fundamentally different transaction structure than buying Apple shares through NASDAQ.

Why Most Penny Stocks Don’t Qualify for Major Exchanges

NASDAQ and NYSE maintain minimum listing standards, including share price thresholds, market capitalization requirements, and corporate governance standards. 

Companies trading below $1 typically can’t meet the minimum bid price requirement ($1 for NASDAQ, $1 for NYSE) or lack the financial metrics and shareholder equity needed for continued listing.

OTCQX, OTCQB, and Pink Sheets: The Three-Tier OTC Structure 

OTC Markets Group, the private company operating the dominant OTC trading platforms, maintains a three-tier structure that segments securities by the quality of their disclosure and financial reporting.

OTCQX: The “Best Market” with Highest Standards

OTCQX represents the top tier for OTC-traded securities, requiring companies to meet higher financial standards, undergo annual verification and management certification, and maintain current disclosure with the SEC or appropriate regulatory authority. Companies on OTCQX must have a $2 million minimum bid price test and cannot be in bankruptcy. 

OTCQB: The “Venture Market” for Developing Companies

OTCQB serves as a middle tier for early-stage and developing U.S. and international companies. These companies must report to the SEC or appropriate regulator, undergo an annual verification and management certification process, meet a minimum bid price test of $0.01, and not be in bankruptcy. 

Pink Sheets: The Unregulated Bottom Tier

Pink sheets, named for the color of paper on which quotes were historically printed, impose essentially no financial standards or reporting requirements. Companies can trade on the Pink Sheets without SEC registration, current financial disclosure, or regulatory compliance.

Grey Market: Where Stocks Go to Die

The grey market refers to securities that are no longer eligible for public quotation on OTC platforms, typically because they failed to provide required information or pay OTC Markets Group fees. Trading these securities requires contacting brokers directly by phone, and bid-ask spreads can reach extraordinary levels when transactions occur at all.

Major Exchange-Listed Penny Stocks: NASDAQ and NYSE

Some securities trading under $5, and occasionally under $1, maintain listings on major exchanges despite their low prices. These represent a distinct category from OTC penny stocks, carrying advantages in transparency and liquidity but facing unique delisting pressures.

Current major exchange-listed U.S. penny stocks under $1 include:

• TEN Holdings Inc. (NASDAQ: XHLD) 
• Hyperscale Data Inc. (AMEX: GPUS)
• Nuburu Inc. (AMEX: BURU) 
• AtlasClear Holdings Inc. (AMEX: ATCH)

These stocks can be found by searching major exchange listings on platforms like NASDAQ.com and NYSE.com, or by using comprehensive stock screeners that filter by price range and exchange.

Key Differences Between Exchange Venues That Affect Investors 

Structural differences extend beyond price and volatility. Major exchanges require full financial disclosure and continuous regulatory oversight. OTC markets vary widely in reporting quality. Some companies publish detailed filings, while others rely on limited disclosures or exemptions.

Moreover, exchange-listed stocks generally trade with tighter bid-ask spreads and higher volume. OTC stocks often experience wider spreads due to dealer-based pricing and limited competition.

How Trading Platforms Handle Different Penny Stock Venues 

Brokerage firms apply different policies depending on where penny stocks trade. Many platforms restrict or limit access to Pink Sheet and Grey Market securities. Some require special approvals for OTC trading. Others block certain securities entirely.

Fee structures also vary. OTC trades frequently carry higher commissions or per-share fees. With low-priced stocks, transaction costs can significantly affect performance.

How to Spot Danger in Trading Venues

Certain warning signs indicate particularly dangerous penny stock listings that carry elevated fraud risk, extreme illiquidity, or near-total information vacuums.

The “Yield” and “Expert Market” Designations

OTC Markets Group assigns a “yield” sign to securities where information is limited or not current, indicating that investor caution is advised. 

The “Expert Market” designation went into effect in September 2021 for securities with no current information, restricting trading to institutional investors and excluding retail participants, effectively a death sentence for liquidity.

Stocks with No Current Information Available

Pink-sheet securities with no financial updates for 6-12 months or longer are red flags. Companies may have ceased operations, management may have abandoned the entity, or the listing may serve primarily as a vehicle for stock promotion schemes. 

Without current information, investment analysis becomes impossible and speculation purely speculative.

Caveat Emptor and Other Warning Labels

OTC Markets applies a “Caveat Emptor” (buyer beware) skull-and-crossbones icon to securities with public interest concerns, including suspected fraud, spam campaigns, or regulatory suspensions. 

Other warning designations include “Unsolicited Quotes Only,” which indicates that brokers can respond only to investor requests rather than actively market shares, which is typically an indication of extreme illiquidity or compliance issues.

Final Thoughts

Penny stocks may trade at low prices, but they do not have an equal footing. Transparency, liquidity, and oversight decline sharply from major exchanges to OTC tiers and Pink Sheets.

Venue analysis separates traders who control their exits from those who hope someone will eventually buy their shares.

For this reason, before focusing on price action or hype, ask yourself: If the stock can’t be sold when needed, does the potential gain justify the risk of being trapped in an illiquid position?
