How to research a stock from the filings up

Build an evidence trail from business model to valuation.

Stock research begins with a business and ends with a price-sensitive judgment. A popular ticker, compelling product, or rising chart is a starting question, not a completed analysis.

Build a compact research packet

Collect the latest annual report, recent quarterly reports, proxy statement, earnings release, and relevant material-event filings. Record the reporting periods and distinguish audited financial statements from management's forward-looking commentary.

Explain how cash is earned

Identify customers, products, pricing, competitors, and major costs. Trace revenue into operating profit, cash flow, capital spending, and per-share outcomes. Ask whether growth consumes cash or generates it.

Set up three scenarios

Use a base, weaker, and stronger operating case with explicit assumptions for growth, margins, reinvestment, and dilution. Connect each to a valuation range. This makes disagreement visible instead of hiding it in a single target price.

Write what could change your mind

Choose measurable evidence that would invalidate the thesis. Review the balance sheet and risks before deciding position size. Save source links and dates so the next review can distinguish new information from a changing market mood.
