Key Points

  • Micro-caps are the smallest publicly traded companies with under $300 million market caps.
  • These companies often trade over-the-counter (OTC) and have minimal analyst coverage.
  • Micro-caps are the most volatile stocks in the market and should only be traded by experienced investors with a high risk tolerance.
  • MarketBeat previews top five stocks to own in May.

For a non-investor, $300 million is usually considered anything but micro.

However, the smallest companies in capital markets still often have market caps totaling hundreds of millions of dollars. But the market cap alone doesn’t tell us much unless we’re comparing it to other stocks, and when the biggest companies are topping the trillion-dollar market cap level, a $300 million market cap does seem quaint. 

Micro-caps are the smallest and most volatile public equities. They often trade over the counter, where the rules are less stringent than those of major exchanges like the NYSE or NASDAQ. These stocks often gyrate wildly throughout the day, creating opportunities for massive gains and disastrous losses.

Think you have the risk tolerance to trade these volatile companies? In this guide, we’ll cover everything you need to know about micro-caps, including their benefits, risks, and strategies you’ll need to utilize for success.

What Are Micro-Cap Stocks?

In the movie The Wolf of Wall Street, investor/conman Jordan Belfort got his start trading pink sheets, which are small companies trading on unregulated exchanges with minimal coverage. Belfort sold these securities as life-changing opportunities (while collecting a hefty commission), but these stocks were unstable micro-caps with little chance of long-term success. 

Micro-caps get a bad rep due to people like Belfort. While they are risky companies not designed for long-term holding, they also can be short-term trading vehicles that produce outsized profits.

Generally, these companies have a market cap between $50 million and $300 million, which means a relatively small amount of capital can influence large price swings. These stocks often reside in emerging markets or niche industries, so due diligence is imperative. 

Benefits of Investing in Micro-Cap Stocks

Investing in micro-caps requires an appetite for risk and the ability to perform diligent technical and fundamental analysis. If you decide to venture down the micro-cap path, here are a few benefits:

1. High Growth Potential

Many investors dream about "getting in early" on the next big winner. While few micro-caps grow big enough to shake up an industry like Netflix (NASDAQ: NFLX) or Amazon (NASDAQ: AMZN), there are instances of micro-caps winning a government contract or creating an innovative product that caused the stock to go parabolic.

2. Under-the-Radar Opportunities

Micro-caps have minimal analyst coverage and don’t have to issue the same financial statements and reports as companies on major exchanges. However, this can benefit investors who can identify opportunities before the rest of the market.

3. Portfolio Diversification

If you want to diversify away from large-cap stocks that mostly move in lockstep, micro-caps tend not to be correlated with broader market moves. 

Risks of Micro-Cap Investing

But it's not all sunshine and roses. Here are the drawbacks of investing in micro-cap companies:

1. High Volatility

Micro-caps can double, triple, or even quadruple in price within a single session and give it all back the following day. Thus, these stocks are better suited as trading vehicles than long-term investments.

2. Less Efficient

Micro caps are often less efficient due to their low share floats, making filling orders difficult and pricing less accurate (usually resulting in high spreads).

3. Limited Transparency

Companies trading on the NYSE or NASDAQ must meet certain financial requirements and file specific regulatory paperwork. While OTC stocks are still regulated, the parameters are less strict.

4. Liquidity Concerns

Micro-caps have low trading volume, which can create liquidity issues when trying to execute an order. A stock that gains 400% in a day does an investor no good, and they can’t find a willing buyer for the shares to cash out their gain.

5. Potential for Fraud

Due to looser regulatory rules and thin trading, micro-caps are a breeding ground for scammers and pump-and-dump artists. Always be cautious of social media gurus promoting micro-cap companies.

Risk Management Tips for Micro-Cap Investors

  • Diversify Investments: Never put all your money into a single stock, especially a volatile micro-cap.
  • Limit Exposure: Keep your capital allocation small when buying micro-caps.
  • Thorough Research: You must review all available financial data before investing carefully. And without analyst coverage, you’ll be doing most of this research yourself.
  • Be Skeptical of Hype: That Twitter investor who located the "next big thing" may not have your best interests at heart. Micro-caps make for easy pump-and-dumps, so avoid social trading with these securities.
  • Plan Entry and Exit Strategies: Always have an escape plan. Micro-caps aren’t meant for long-term holding; get in and get out with a profit whenever you can.

Who Should Invest in Micro-Cap Stocks?

Micro-cap stocks are often viewed as the Wild West of the stock market. If you fall into one of the following investor types, micro-caps might be for you.

Investors Seeking Explosive Growth

Micro-caps are the infants of the market—new and growing companies without a sales history or a functional product. These companies could produce exponential returns if you’re willing to take the risk.

High-Risk Tolerant Investors

How comfortable are you riding the rollercoaster? Micro-caps aren’t for risk-averse investors, so you must have a strong stomach for volatility to trade these successfully.

Experienced Researchers

If you’re an investment research wizard, micro-caps could be a place to prove your chops. You’ll need to piece together a thesis from limited information, so a keen eye and good gut feeling are necessary.

Long-Term Investors with Patience

If you’re willing to ride out the volatility, micro-caps can produce long-term gains if the company makes a viable product. However, be cautious about owning micro-caps for extended durations and be prepared to unload shares quickly if the thesis changes. 

Diversified Investors Seeking Higher Returns

If you have a diversified stock profile and want to set aside some capital for riskier endeavors, using micro-caps as potential lottery tickets could increase your returns without harming your overall portfolio.

Who Should Avoid Micro-Cap Stocks? 

Micro-cap stocks can offer lucrative upside potential, but they’re not suited for every investor. Their volatility, lack of transparency, and high risk make them a poor fit for certain investing styles and financial goals. Here’s who should steer clear:

If you prioritize preserving your capital over chasing high returns, you should avoid micro-cap stocks. The extreme price swings that characterize these investments can lead to sudden and significant losses, which can be difficult for cautious investors to stomach.

Short-Term Traders Seeking Stability

Those who rely on predictable price movements for quick trades may find micro-cap stocks frustrating. Due to their low liquidity and erratic trading patterns, these stocks can experience unpredictable price gaps that make short-term strategies unreliable.

Retirees and Near-Retirees

If you are approaching retirement or are already retired, you typically need a stable income stream. The unpredictable nature of micro-cap stocks makes them unsuitable for those who cannot afford to lose significant portions of their savings.

Inexperienced Investors

Beginners who are still learning the ropes of investing should avoid micro-caps. Analyzing these stocks requires advanced research skills, critical thinking, and an ability to navigate hype and limited public information—areas where inexperienced investors often struggle.

To buy micro-caps, you must be active, constantly following company data and altering positions as needed. You can’t "set it and forget it" with micro-caps.

How to Identify High-Potential Micro-Cap Stocks

If you invest in micro-caps, you’ll need a plan of attack. Micro-caps can be difficult to gauge since reporting requirements are weaker, but here are a few tips for finding quality companies.

Analyze Financial Metrics

Look for consistent year-over-year increases in revenue growth and assess whether the company is moving toward profitability by reviewing margins. Avoid companies with unsustainable debt levels by checking Debt/Equity ratios.

What are the hot investment sectors of the moment? Look at enticing sectors like biotech, AI, or other tech industries. Stay on top of regulatory and government action that could influence the company's outlook.

Evaluate Management Teams

What history does the C-suite have? Consider ownership’s track record, experience, and alignment with shareholder interests.

Competitive Edge

These companies are constantly looking to disrupt incumbents. Look for micro-caps with intriguing products or services that could give you a competitive advantage.

Use Stock Screening Tools

MarketBeat's stock screener and other tools allow you to filter stocks based on financial metrics and market performance.

Strategies for Investing in Micro-Cap Stocks

Here are five basic strategies to consider when getting started with micro-cap stocks:

1. Adopt a Long-Term Perspective

These companies are often in the prototype stage and may take years to produce a viable product.

2. Use Dollar-Cost Averaging

Some investors prefer to invest all their capital at once, but with volatile micro-caps, a dollar-cost averaging strategy might be more prudent.

3. Consider Exchange-Traded Funds

Yes, there are micro-cap ETFs! For example, the First Trust Dow Jones Select Microcap ETF (NYSEARCA: FDM) holds 140 different micro-caps from various sectors and industries.

4. Blend with Larger-Cap Investments

Always use micro-caps for a small risk-seeking portion of your portfolio, but mix with large-caps to prevent excessive volatility.

5. Smaller Allocation

Never invest more in micro-caps than you can afford to lose. You might find a parabolic winner, but you also might buy a stock that loses 70% of its value in a day. Always keep position sizes small.

Is Micro-Cap Investing Right for You?

Micro-cap investing can be tempting due to the potential gains, but it's an area of the market fraught with risk. Trading stocks off the major exchanges is always risky since volatility is high and reporting requirements are low, so you’ll need to exercise caution and perform exhaustive due diligence. Use MarketBeat’s screening tools to find companies that meet your criteria and adopt a disciplined approach to trading. Micro-caps offer great rewards, but they aren’t meant for anxious investors.
