PortCompany Financial Ratios — The Ones That Really Matter
No single ratio works in isolation. Here are the six most important ones and the inherent trap in each.
Valuation: P/E and P/B
The price-to-earnings ratio tells you how much you're paying for one zloty of annual profit. A high ratio indicates high market expectations; a low one suggests either an opportunity or a problem. Without comparison to the industry and the company's history, it's useless.
The trap: A cyclical company has its lowest P/E at the peak of its cycle, when profits are at record highs and about to fall. The lowest ratio can therefore be the worst time to buy.
Profitability: Margins and ROE
The operating margin best describes the business itself because it's independent of the financing structure. ROE shows how much profit a company generates from its owners' capital.
The ROE trap: High debt reduces equity and artificially inflates the ratio. That's why ROE should always be read in conjunction with the debt level.
Debt: Net Debt to EBITDA
The ratio of debt (minus cash) to operating profit (plus depreciation). Above three to four, a company becomes sensitive to interest rate increases.
The EBITDA trap: Overlooked depreciation represents the real wear and tear of assets that will eventually need to be replaced. High EBITDA with consistently negative cash flow does not indicate a healthy company.
How to use ratios intelligently
- Compare within the same industry — a bank and a game developer have incomparable ratios.
- Look at the trend, not a single reading.
- Check whether earnings are supported by cash flow.
- Don't base decisions on a single number—each one can be misleading in certain situations.
Frequently Asked Questions
Which ratio is most important?
No single one. Valuation without profitability tells you nothing, and profitability without debt can be misleading. The minimum set includes valuation, operating margin, and net debt to EBITDA.
Does a low P/E ratio indicate an opportunity?
Not necessarily. It often means the market expects earnings to fall — for example, at the peak of a cycle for a cyclical company.
