Understanding a company, about 14 min

How to analyse a company, in a sensible order

Analysis is not about finding a formula. It is about answering five questions in the right order, and being honest when you cannot answer one of them.

Last checked August 2026.

The short version

  • Understand what the business sells and to whom, before opening any spreadsheet.
  • Then check quality: , margins, cash, and across several years.
  • Then judge management, using the record rather than the presentation.
  • Only then look at the price. Price is the last question, never the first.
  • Write down the reason and what would change it. If you cannot, you do not have an analysis.

Step 1. Understand the business

Before any number, answer these in ordinary language. If you cannot, the honest response is to stop, and that is a legitimate outcome.

  • What does this company sell, and who buys it?
  • How does it actually make money? Volume, price, subscription, interest spread, commission.
  • Who are its competitors, and why would a customer choose this one?
  • What would have to happen for this business to be in trouble?
  • Is the market it serves growing, flat, or shrinking?

That fourth question is the one people skip and the one that matters most. If you cannot describe how this business fails, you have not understood it, you have only admired it.

The concentration questionsHow much revenue comes from the largest customer? From one product? From one geography? A business earning 60% of revenue from a single customer is a very different risk from one with ten thousand customers, and no ratio will tell you this. It is in the annual report.

Step 2. Check the numbers, over years

One year tells you almost nothing. Look at five to ten years and read the direction and consistency, not the latest figure.

What to look atWhat you are asking
over 5 to 10 yearsIs the business genuinely growing, or standing still?
trendIs it keeping its pricing power, or giving it away?
over the periodDoes it earn a good return on the capital it uses?
and interest coverageCould a bad year threaten it?
Operating cash vs Is the profit turning into actual money?
Does it fund itself, or depend on raising money?

The single most useful check on that list is the fifth. Reported profit involves judgement. Cash does not. A company where profit rises steadily while cash from operations does not follow is telling you something, and it usually becomes visible in the accounts long before it becomes visible in the share price.

Include at least one bad year in your window if you can. How a business performed in a downturn tells you more about its resilience than three good years tell you about its quality. See financial ratios for how to read each of these.

Step 3. Judge management

This is the part that cannot be automated and, over a long holding period, may matter more than the numbers. You are asking one question: can these people be trusted with money that is partly yours?

  • Do they do what they said? Read three consecutive annual reports and check stated intentions against outcomes.
  • How do they describe a bad year? Responsibility or excuses. This is highly informative.
  • Are small and explainable, or large and growing?
  • Is promoter holding stable, and is any of it ?
  • Has the auditor ever qualified the accounts or resigned?
  • How is capital allocated? Reinvested well, paid out sensibly, or spent on unrelated acquisitions?

That last one deserves attention. A business generating cash has to decide what to do with it, and those decisions compound over decades. A management team that repeatedly buys unrelated businesses at high prices will destroy value no matter how good the core operation is.

Step 4. Only now, the price

Price comes fourth deliberately. Judging price first is how people end up owning cheap bad businesses, which is the most common way beginners lose money slowly.

At this stage you know whether it is a good business. The remaining question is whether today price is reasonable for what you now understand.

  • How does the compare with this company own history, not just with peers?
  • What growth rate is the current price implicitly assuming, and is that plausible given the last decade?
  • If growth turned out to be half what is expected, what would the share be worth?
  • Where is the margin of safety? What can go wrong without you losing money?

A useful discipline: decide what price you would be happy to pay before you look at the current price. It stops you working backwards from the number on the screen to a justification for it, which is what most of us do by default.

And accept the most common honest conclusion in investing: a good business at too high a price is not a buy. It is a watch. There is no rule requiring you to act today.

Step 5. Write it down

This is the step that turns analysis into something you can actually use later, and it is the whole idea behind AlphaVik.

Before buying, write down four things. Three sentences will do.

  • Why I am buying. The two or three specific reasons.
  • The evidence. The numbers or facts those reasons rest on.
  • The risks. What I already know could go wrong.
  • What would change my mind. The specific events that would make this no longer worth owning.

Eight months later the price will have moved and you will feel something about it. That note is the only thing that can tell you whether the business changed or only the price did. Without it, you are relying on memory, which quietly rewrites itself to match how you currently feel.

The test of a real analysisIf you cannot name the specific event that would make you sell, you have not finished analysing. A conviction with no exit condition is not a conclusion, it is an attachment.

The honest limits of this

Two things worth saying plainly, because most guides on this subject do not.

Doing this well is a lot of work. Properly analysing one company takes hours, and a portfolio of fifteen needs ongoing attention every quarter. Most people who intend to do this end up not doing it, and then hold individual stocks with no current view on them. That is worse than not picking stocks at all.

You are competing with professionals. Analysts with teams, databases and direct access to management are studying the same companies. You are not going to have an information advantage. Where an individual can have an edge is patience, because you have no quarterly performance to report and can wait years for a view to play out.

None of this means do not learn it. Understanding how a business is judged makes you better at every financial decision you make, including choosing funds. But if you are not going to do the ongoing work, an index fund is not a lesser choice. It is the honest one.

What to remember

  • Understand the business in ordinary language before opening any spreadsheet.
  • Read numbers across five to ten years. Direction and consistency matter more than the latest figure.
  • Profit rising while operating cash does not follow is the most useful warning sign available.
  • Judge management by their record across consecutive annual reports, not by their presentation.
  • Price is the fourth question. Judging it first leads to owning cheap bad businesses.
  • If you cannot name what would make you sell, the analysis is not finished.

Common questions

How do I analyse a company before investing?
Work in order. Understand what the business sells and how it could fail, check the numbers across five to ten years for quality and safety, judge management by their record across consecutive annual reports, then assess whether the price is reasonable, and finally write down your reason and what would change it.
What is the most important thing to check in a company?
Whether reported profit is turning into actual cash from operations. Profit involves accounting judgement while cash does not, so a persistent gap between the two is the earliest and most reliable warning sign an ordinary investor can find.
How many years of data should I look at?
Five to ten years, and ideally a period that includes at least one difficult year. How a business performed in a downturn tells you more about its resilience than several good years tell you about its quality.
Should I look at the share price first?
No. Judging price before you understand the business is how investors end up owning cheap companies that deserve to be cheap. Establish whether it is a good business first, then ask whether today price is reasonable for what you found.
Is company analysis worth it for a small investor?
Learning it improves every financial decision you make, including choosing funds. But doing it properly takes hours per company and ongoing work every quarter. If you are not going to keep that up, a broad index fund is the honest choice rather than holding individual stocks you no longer have a current view on.
