Does a stock with a low price automatically feel like a bargain? What about that small, publicly held company you just read about on social media that nobody knows about, but is poised to become the next NVIDIA (NVDA) or Amazon (AMZN)?

Welcome to the world of micro-cap and penny stocks. They’re affordable, often over-hyped moonshots that could offer up a 10,000% return on your money … or cost you your entire investment. In a way, they’re the parlay bets of the investing world.

Get familiar with these types of stocks—including how to allocate your funds responsibly and assess the risks and potential rewards—before making any portfolio decisions.

The formal definition of micro-cap stocks are those of publicly traded companies with a market capitalization between $50 million and $300 million. Penny stocks are those that trade for less than $5 per share, regardless of the company’s market value.

Micro-cap and penny stocks have plenty in common:

But what are the key differences? The most obvious contrast is that micro-cap stocks have a wide price range, while penny stocks are always under $5.

Penny stocks generally trade only via over-the-counter (OTC) markets, whereas micro-cap stocks may be listed on major exchanges such as the Nasdaq and the New York Stock Exchange. Because of this, micro-cap stocks are often better regulated. Publicly available information about penny stock companies can be hard to find.

Investing in either micro-cap or penny stocks is risky—but penny stocks, which bear some resemblance to lottery tickets, confer the greatest risk. That’s because:

With small market capitalizations, these companies typically don’t have well-known brands. Here are some examples of micro-cap and penny stocks.

Buying the shares of any micro-cap or penny stock confers risk. That’s unavoidable—all investing does, to some degree—but you can proactively minimize your risk by conducting plenty of research and setting realistic expectations.

Use these best practices to avoid potentially regrettable investment choices.

Analyze financial statements. Before investing, review company financial statements. Look for negative indicators such as declining revenue, increasing debt, cash flow problems, and pending litigation. You can use the Securities and Exchange Commission’s EDGAR database to access company filings, including quarterly and annual reports.

Check bond ratings. Not every micro-cap or penny stock company issues bonds, but the bond ratings for a company can convey useful information. A low rating from one of the “big three” ratings agencies—Moody’s, Fitch, or Standard & Poor’s—is an important indicator of the company’s ability to meet its financial obligations (i.e., avoid bankruptcy).

Evaluate the management team. How strong is the leadership? Research the experience, track records, and credibility of the management team to help guide your investment decision.

Know the industry. Get familiar with the sector or industry before adding any micro-cap or penny stocks to your portfolio. Explore the industry’s economic trends, competition, and regulatory changes.

Be skeptical of hype. You know the saying about things that sound too good to be true. Keep your expectations in check and don’t automatically believe any promotional hype.

Diversify your investments. A diversified portfolio that includes some micro-cap or penny stocks is a lot safer than a portfolio that invests only in risky securities. Diversification typically lowers your overall portfolio risk.

Don’t invest more than you can afford to lose. Set limits to guide your investing strategy and control your risk. With micro-cap and penny stocks, limit your exposure to an amount you’re willing to lose.

Low price tags and high growth potential can make penny and micro-cap stocks feel alluring. But some things are cheap for a reason, and that reason could be a low likelihood of (or an uncertain path to) profitability for that micro-cap or penny stock.

Modern investing is a double-edged sword. On the one hand, you’ve never had better access to fundamental information through a number of brokerage and/or data platforms. On the other hand, the ease with which misinformation, rumors, and hype can spread over social media has never been higher.

We all love to capture opportunities and be on the front end of the next big thing. But we all hate to lose money, and we abhor getting scammed. Do your homework before adding any micro-cap or penny stock to your securities portfolio, and remember that advice you learned as a kid: “If it seems too good to be true, it probably is.”
