How to Research a Micro-Cap: A Filings-First Checklist

To research a micro-cap, start with the company’s SEC filings on EDGAR and check every claim in a press release or message-board post against them. The SEC’s own guidance says the biggest difference between micro-caps and other stocks is the amount of reliable public information, so the research method is mostly about finding primary documents and reading them in a set order.

This guide gives a filings-first checklist that retail investors in micro-cap and OTC stocks can reuse for any ticker. It describes how to gather facts. It does not say which stocks to look at or what to do with what you find.

Step 0: Know what you are looking at

“Micro-cap” is a size label. The SEC’s investor bulletin says companies with a market capitalization below roughly $250 or $300 million are often called microcap stocks, and those below $50 million are sometimes called nanocap stocks. “Penny stock” is a legal definition. Under Exchange Act Rule 3a51-1, a penny stock is any equity security other than those the rule excludes, which include certain exchange-listed NMS stocks, securities issued by registered investment companies, and securities with a price of five dollars or more, each with detailed conditions. A stock can be a micro-cap and not a penny stock, or the reverse. See penny stocks and OTC markets explained.

Step 1: Find out whether the company reports to the SEC

Search the company name or ticker in EDGAR. The SEC’s research guide notes that EDGAR results appear in chronological order and that the form type appears in the first column. A “10-K/A” indicates an amendment to a 10-K.

• Files with the SEC: go to Step 2.
• Does not file with the SEC: the SEC’s bulletin says many microcap companies do not file reports, which makes it hard to get facts about management, products, services and finances. The same bulletin points to the company itself, the OTC Markets website, your state securities regulator and the Secretary of State where the company is incorporated. Treat limited information as a finding, not a gap to fill with assumptions.

Reporting status also affects whether a stock can be quoted over the counter. Rule 15c2-11 restricts broker-dealers from publishing quotations for OTC stocks that have not provided current and publicly available financial information.

Step 2: Read the filings in this order

1. Latest 10-K (annual report). Audited annual financial statements, risk factors, a description of the business, and management’s discussion of results. The SEC’s guide describes the 10-K as providing audited annual statements, material risk factors and MD&A.
2. Every 10-Q since. Unaudited quarterly statements and an update on risks. See how to read a 10-Q.
3. Every 8-K since the 10-K. Events between the periodic reports. Scan the item numbers first. See how to read an 8-K.
4. Definitive proxy statement (DEF 14A). Who the directors and officers are, how they are paid, and who owns more than 5 percent.
5. Registration statements and prospectuses. Any S-1, S-3 or 424B filings, which describe offerings and the terms of securities being sold.

Step 3: Check the numbers that matter most for small companies

• Cash versus cash burn. Cash on the balance sheet and net cash used in operations from the cash flow statement. If you compute runway from them, label it an estimate and state your method.
• Share count over time. The cover pages of the 10-K and each 10-Q show shares outstanding as of the latest practicable date. Rising counts usually trace to Item 3.02 8-Ks or Part II Item 2 of the 10-Q. See stock dilution and float vs shares outstanding.
• Debt and convertibles. The notes list maturities, conversion terms and defaults. Part II Item 3 of the 10-Q covers material defaults on debt. See convertible notes explained.
• Going-concern language. Read the liquidity section of the MD&A and the notes for any statement about the company’s ability to continue operating.
• Controls. Item 4 of the 10-Q and the equivalent in the 10-K disclose weaknesses in internal control, if any.

Step 4: Check who owns it and who runs it

The SEC lists large insider ownership as a red flag in many pump-and-dump cases, and notes that convertible instruments can mask control over large portions of a company’s stock. Check the proxy statement for beneficial ownership, then Schedules 13D and 13G for holders above 5 percent, and Forms 3, 4 and 5 for officers, directors and holders above 10 percent. Form 4 reports transactions within two business days.

Read the management biographies in the 10-K or proxy statement. The SEC’s bulletin suggests considering whether management has the background or expertise needed to execute the business plan. Use EDGAR full-text search, which covers filings since 2001, to see whether the same names appear in the filings of other companies.

Step 5: Check the auditor and the reporting record

Item 4.01 8-Ks report changes in the certifying accountant, and Item 4.02 reports that previously issued financial statements should no longer be relied upon. The SEC’s 8-K bulletin notes that an auditor change is sometimes, but not always, a cause for concern, depending on the reasons. Also look for notifications of late filing (NT 10-K and NT 10-Q). Under Rule 12b-25, a company that meets the conditions has an extra 15 calendar days for a 10-K and 5 calendar days for a 10-Q.

Step 6: Check for promotion, suspensions and flags

The SEC’s risk bulletin lists these as red flags: SEC trading suspensions; stock promotions, including by email, text message and social media; unexplained moves in price or volume; no history of operational success alongside large projected revenues; large insider ownership; and signs of no real business operations, such as frequent or unexplained changes in name or business, little or no assets, minimal revenues, or implausible press releases. It also says to look closely at companies that became public through a reverse merger or recently did a reverse stock split.

• Trading suspensions. The SEC can suspend trading in a stock for up to ten business days when it believes it necessary to protect investors and the public interest, for example where there is a lack of current information. Check the SEC’s list of trading suspensions. See SEC trading suspensions.
• Caveat Emptor. OTC Markets places a skull-and-crossbones icon next to the ticker as notice of a potential public interest concern, and says it may use the designation where promotion presents such a concern or the company has not made adequate current information available.
• Corporate history. Name changes, reverse splits and reverse mergers appear in 8-Ks, with Item 5.03 for charter amendments and Item 2.01 for acquisitions. See reverse stock split and shell company.

Step 7: Verify every claim against a filing

For each statement in a press release, social post or newsletter, find the filing that says the same thing. If a company announces an agreement, look for the 8-K under Item 1.01 and read the exhibit. If it announces revenue, look for the figure in the 10-Q. If it announces a financing, look for Item 3.02 or a prospectus. If you cannot find the filing, record that the claim is unverified. The SEC’s bulletin cautions against using unsolicited emails, message board postings and company news releases as the sole basis for investment decisions.

Red flags vs normal

• Normal for small companies: Net losses, periodic financings, a short risk-factor section in a 10-Q, a wide bid-ask spread, thin trading.
• Worth a closer read: The patterns in Step 6, a share count that rises every quarter, repeated late filings, and press releases with no matching filing.
• A limit of this method: Reading filings does not tell you what a stock will do. The SEC’s own guidance is that readily available information, or filing reports with a regulator, does not mean it is safe to invest in a company.
