Explain how the business makes money
If you cannot explain the customer, product, pricing, cost structure, and competitive advantage in plain language, keep researching.
Customer and problem solved:
Product or service and pricing model:
Primary revenue drivers:
Largest costs and margin drivers:
Competitive advantage and evidence:
Management incentives and capital allocation:
Industry structure and major threats:Read the three financial statements together
The income statement shows profitability, the balance sheet shows resilience, and the cash-flow statement tests whether accounting earnings become cash.
| Statement | Read first | Red flags to investigate |
|---|---|---|
| Income statement | Revenue, gross margin, operating margin, EPS trend | Declining revenue, margin compression, expenses outrunning growth |
| Balance sheet | Cash, debt, working capital, dilution, goodwill | Debt growing faster than the business, weak liquidity, repeated share issuance |
| Cash-flow statement | Operating cash flow, capex, free cash flow, financing | Earnings without cash, persistent cash burn, financing-dependent operations |
Estimate a range instead of one magic number
Valuation is an assumption system. Compare the company with peers and its own history, then model conservative, base, and optimistic cash-flow outcomes.
Compare like with like
Use P/E, PEG, EV/EBITDA, or another relevant multiple inside the correct sector and growth context.
Follow free cash flow
Check free-cash-flow yield and whether cash generation can support the valuation.
Model scenarios
Project conservative cash flow, terminal assumptions, and a discount rate as a range—not a precise promise.
Demand room for error
A margin of safety protects against bad assumptions; it does not remove business or market risk.
Write a falsifiable investment thesis
A thesis states why expectations are wrong, what evidence could close the gap, and exactly what would prove you wrong.
Company / asset and intended horizon:
Variant view: what the market may misunderstand:
Business quality evidence:
Valuation range and key assumptions:
Catalysts and expected evidence dates:
Base / upside / downside scenario:
Thesis invalidation:
Liquidity, dilution, leverage, and concentration risks:
Reason to buy, wait, reduce, or pass:Use a source hierarchy
Begin with primary company and regulatory evidence, then use secondary research to challenge and contextualize it.
- 01
Read the latest annual and quarterly filings, footnotes, and risk factors.
- 02
Compare earnings releases with the cash-flow and balance-sheet changes.
- 03
Read management guidance and track whether prior guidance was achieved.
- 04
Use industry and competitor filings to test the company narrative.
- 05
Record each important claim with its source date and the next evidence checkpoint.
Next steps
Move from a researched thesis to a portfolio decision and monitoring plan.
