How to analyze a company
Understand the business before the numbers, then test its industry, economics, competitive position, management, risks and valuation with primary documents where possible.
1. Understand the business
Write down what the company sells, who pays, how it reaches customers and what makes a customer stay. If you cannot explain the business in a few sentences, more research is probably needed before interpreting financial ratios.
2. Map the industry
Identify competitors, suppliers, substitutes and the factors that determine price and demand. Industry structure matters because a good operator in a difficult market may face different constraints from a good operator in a concentrated one.
3. Read the economic model
Look at how revenue becomes operating profit and cash. Ask which costs are fixed, which are variable, how much reinvestment is required and whether growth creates or consumes cash. Compare several periods instead of treating one quarter as a complete story.
4. Test the competitive position
List the company’s claimed advantages and ask what would stop a competitor from copying them. This is where concepts such as switching costs, network effects, cost advantages and pricing power become useful. MoatCheck can help organize a first pass through public information.
5. Write down what could go wrong
Include competition, regulation, concentration, execution, balance-sheet pressure and changes in customer behavior. A good research note should explain what evidence would change your mind, not only why the company looks attractive.
6. Separate research from a decision
Understanding a company does not automatically tell you what price is reasonable or whether it fits your circumstances. Keep those questions separate and make uncertainty visible.

Frequently Asked Questions
What should I look at first?
Start with what the company sells, who pays, why customers choose it and how that activity becomes cash and returns.
Which documents are useful?
Company filings, annual reports, earnings materials and competitor disclosures help compare claims with evidence.
Is company analysis enough to make an investment decision?
No. Analysis is one input and does not remove uncertainty, portfolio constraints or the need for independent judgment.
