Understanding Penny Stocks

Updated: Feb 19

Penny stocks refer to shares of small public companies that trade at relatively low prices, typically under $5 per share, according to the U.S. Securities and Exchange Commission (SEC). While they can offer significant potential for high returns due to their low prices, they also come with a high level of risk.

Characteristics of Penny Stocks

The defining features of penny stocks generally include:

  • Low Share Price: Penny stocks trade at less than $5 per share, with many trading for mere pennies.

  • Small Market Capitalization: They're typically issued by small companies with a market capitalization (total market value of a company's outstanding shares of stock) under $300 million.

  • Limited Information: Information about the companies that issue penny stocks may be difficult to find, leading to less transparency compared to more well-known companies.

  • High Volatility: Penny stocks often experience drastic fluctuations in price.

  • Lack of Liquidity: These stocks often lack liquidity, meaning they may be hard to sell, especially in large quantities.

  • Trade Over-the-Counter (OTC): Instead of trading on major exchanges like the New York Stock Exchange or the Nasdaq, many penny stocks trade over the counter through platforms like the OTC Bulletin Board (OTCBB) or the Pink Sheets.

Potential Benefits and Risks of Penny Stocks


  • High Return Potential: The low price of penny stocks means that even a small increase in price can result in a high percentage return. For instance, if a stock that costs $0.10 per share increases by $0.05, that's a 50% return.

  • Affordability: Investors with limited funds can purchase a significant number of shares with a small investment.

  • Opportunity for Growth: Small companies can have significant growth potential, providing the chance for investors to get in on the ground floor.


  • Lack of Transparency: Because many penny stock companies do not file with the SEC, investors may not have access to reliable information about the company's financial situation.

  • Volatility: Penny stocks are notoriously volatile. Prices can skyrocket or plummet on a whim, leading to potentially significant losses.

  • Limited Liquidity: The low volume of trading can make it difficult to sell shares, particularly in larger quantities.

  • High Risk of Fraud: Due to the lack of oversight and regulation, penny stocks can be a hotbed for fraudulent activity, such as the infamous "pump and dump" schemes, where manipulators artificially inflate the price before selling their shares, causing the price to plummet.

An Example of Penny Stock Investment

To illustrate the potential benefits and risks of penny stock investment, let's consider a hypothetical example:

  • Company XYZ is a biotech firm specializing in novel cancer treatments, with its stock trading at $0.50 per share. You believe in the company's research and decide to invest $500, allowing you to purchase 1,000 shares.

  • In the best-case scenario, suppose the company releases encouraging results from a clinical trial, and the stock price surges to $2 per share. Your initial investment of $500 is now worth $2,000, providing a 300% return.

  • However, consider a worst-case scenario where the clinical trials fail. The stock price could drop to $0.10 per share. Your $500 investment would now only be worth $100, leading to an 80% loss.

This example underscores the potential for both significant returns and considerable losses when investing in penny stocks.

Penny stocks can be a part of an investment portfolio, but due to their high risk, they should only represent a small proportion of your overall investment strategy. Additionally, they are best suited for investors who can afford to lose the money they invest and have the time and knowledge to thoroughly research potential investments. Investing in penny stocks is not something to be done impulsively or without due diligence. Make sure to research the company, understand its business model, and scrutinize its financials if available. Also, watch for red flags like extremely low liquidity, lack of information, or sudden, inexplicable spikes in stock price. It is also advisable to diversify your investments rather than pouring all your money into a single penny stock. Diversification can help to mitigate potential losses.

Additionally, keep an eye on the broader market trends. Penny stocks can be heavily influenced by market volatility, and an understanding of these trends can help inform your investment decisions.

Investors should also consider seeking advice from financial advisors who are experienced in dealing with penny stocks. Their knowledge and experience can be invaluable in navigating this high-risk area of investing. While penny stocks offer the potential for high returns due to their low initial price, they also carry significant risk. Therefore, they should be approached with caution, thorough research, and an understanding that any money invested could be lost.


An interesting fact about penny stocks is that they played a central role in the infamous "Wolf of Wall Street" story. Jordan Belfort, portrayed by Leonardo DiCaprio in the 2013 film, made a fortune by manipulating penny stocks. Belfort's firm, Stratton Oakmont, would buy up large quantities of a particular penny stock to inflate its price before selling it off for a substantial profit, leaving other investors to deal with the consequent price crash. This type of scheme, known as a "pump and dump," is illegal and is one of the reasons why investing in penny stocks can be particularly risky.
