Stocks Under the Microscope: How to Do a Quick Company Analysis Yourself
Key takeaways
- A quick company analysis rests on five questions: what it does, what moat it has, how it earns, what it costs, and what threatens it.
- First understand the business in your own words — if you can't explain it, don't buy it.
- The economic moat (competitive advantage) determines long-term quality.
- Valuation (e.g. P/E) tells you whether you're paying too much for expectations.
- This is not a buy recommendation — it's a way of thinking about companies.
In this column we put stocks "under the microscope." Instead of a one-off tip, we'll show you something more durable — a simple five-question framework to quickly form your own view of any company. It is a distillation of what we do in our Company Analyses.
1. What does the company do?
Explain the business in your own words, as if to a friend. How does it make money? Who are the customers? If you can't describe it clearly, that's a warning — don't buy what you don't understand.
2. What is its economic moat?
A moat is a durable competitive advantage that shields profits from competition — a brand, network effect, switching costs, patents, or economies of scale. A company without a moat may have a great year, but over the long run competition will erode its profits.
3. What do the numbers look like?
A handful of indicators tells you a lot: are revenue and profit growing? Are margins healthy? Does the company generate cash (cash flow)? Is it overleveraged? You don't need to be an accountant — a sense of the trend and the order of magnitude is enough.
4. What does it cost (valuation)?
Even a great company is a poor investment at too high a price. A rough indicator is P/E (price to earnings) — a high P/E means you're paying for large expectations and leaves little room for disappointment. Compare it with the company's own history and with peers.
5. What could bring it down?
List the key risks — competition, regulation, dependence on a single product or customer, cyclicality. A good investor thinks first about "what can I lose," only then about the return.
What to take from this
This five-point framework won't make you a professional, but it gives you structure and protects you from buying blindly. And remember — for most people it is simpler and safer to hold a broad index than to bet on individual stocks. Take company analysis as education and entertainment, not a necessity.
FAQ
How do I quickly analyse a stock?
Ask yourself five questions: what does the company do, what economic moat does it have, what do its numbers look like (growth, margins, cash, debt), what does it cost (valuation such as P/E), and what could bring it down. It gives you structure and protects you from buying blindly.
What is an economic moat?
A durable competitive advantage that shields a company's profits from competition — a brand, network effect, switching costs, patents, or economies of scale. A company without a moat may have a good year, but over the long run competitors will erode its profits.
Is P/E sufficient when looking at a stock?
It is a useful rough indicator of price relative to earnings, but not the only one. A high P/E signals high expectations and little room for disappointment. Assess it in the context of the company's growth, its history, and comparable companies — not in isolation.
Is it better to pick individual stocks or hold an index?
For most people, a broad index is simpler and safer — diversification across hundreds of companies without the need for analysis. Selecting individual stocks is legitimate but more demanding and riskier. Treat company analysis primarily as education.
