How to Read a 10-K After a Stock Screen

A screen tells you a company met a rule. It does not tell you whether the rule measured the business you think it measured. That check lives in the filing. A 10-K is the annual report filed with the SEC. A 10-Q is the quarterly version. You do not need to read either one from the first page.

Read toward the number that put the company on the list.

Start with the three statements

The financial statements are short relative to the rest of the document. Read them in this order:

1. Income statement. Revenue, gross profit, operating income, net income. Note whether the growth your screen found shows up in operating income or only in a line below it. A gain, a tax item, or an investment result can lift net income without saying much about the core business.
2. Cash flow statement. Cash from operations, capital expenditures, and the free cash flow those two imply. Compare that with net income. A large gap, in either direction, is the next thing you will look up. The free cash flow yield article covers why the two numbers diverge.
3. Balance sheet. Cash, debt, receivables, inventory, and equity. A growth story funded by a pile of new debt, or by receivables that are growing faster than sales, is a different story from growth funded by customers paying cash.

Three years of annual numbers is enough for a first pass. You are looking for the direction and for anything that jumped.

Then read only the footnotes that touch your rule

The footnotes are where the statements are defined. You will not read all of them on a screen that returned thirty names. You will read the ones that can invalidate the filter.

• If the screen was about revenue growth, read the revenue recognition note. Look for changes in how revenue is counted, a large acquisition, or remaining performance obligations that explain a surge.
• If the screen was about earnings, read anything labeled restructuring, impairment, or non-operating. One-time items belong in your understanding of the year even when they are “adjusted” out of a headline.
• If the screen was about cash flow or debt, read the debt note: what is due within a year, what is fixed versus floating, and whether a covenant is mentioned. Then look at the commitments note for obligations that are real but easy to miss on the face of the balance sheet.

When a footnote changes the number, the company may still be interesting. It is no longer interesting for the reason the screen gave you. Update the reason or drop the name.

Use the MD&A for the company’s own explanation

Management’s Discussion and Analysis is the section where the company explains the year in sentences. Read the parts that match your statements: revenue, margins, liquidity, and capital spending. Treat it as testimony, not as a summary you can skip the tables for. If the MD&A says demand was strong and the cash flow statement says inventory piled up, believe the cash flow statement and keep the sentence as a claim to test next quarter.

Skip the glossy description of the business until a company has survived the statements. A clear product does not repair a cash flow problem. It does tell you what you are researching if the numbers hold.

Jump from the metric to the filing

The practical problem is not motivation. It is finding the right page after a screen has already given you a number. StockWatch stores financial metrics from SEC filings and links a data point back to the source filing, so the check starts at the figure you screened on rather than at the cover page. The metrics reference lists those fields, and the company overview guide describes the company page around them.

A reasonable loop:

1. Run the screen. The screening guide is a way to keep that list short enough to read.
2. Open a name that ranked near the top for the metric you actually care about.
3. Follow the filing link for that metric.
4. Read the three statements, then the one footnote that could overturn the metric.
5. Decide whether the company stays on the list for a real reason.

What you can ignore on the first read

The cover, the table of contents, the long list of risk factors, and the exhibits can wait. Risk factors are written broadly on purpose. They matter when you already know the specific risk — customer concentration, a single product, a refinancing — and you want the company’s own wording. They are a poor place to start.

Auditor’s report: glance at it. A going-concern paragraph or a change in auditor is worth slowing down for. An unqualified opinion is the normal case and not a reason to buy anything.

Keep a note of what you checked

Write one sentence: which metric passed, which footnote you opened, and whether the number still means what you thought. Next quarter you will not remember. The screen will run again. Your note is what keeps the second look faster than the first.

That is the whole method. The filing is long. The path through it is not, if you start from the rule that already fired.
