5 Metrics to Evaluate a Stock

Español · English

A popular company or a rising share price is not enough to justify an investment. Evaluate growth, profitability, cash generation, leverage, and the price you pay. These measures work best together.

1. Revenue growth

Shows whether a company is selling more over time. Sustainable sales growth can support long-term earnings, but it is not enough by itself. Review three to five years and distinguish new customers and pricing from acquisitions. For example, revenue rising from 100 million to 120 million represents 20% growth; it does not prove higher profitability. Warning sign: revenue rises while margins consistently shrink.

2. Operating margin

Operating income divided by revenue shows how much remains after operating costs, before interest and taxes. A 20% margin means 20 out of every 100 in sales becomes operating profit. It matters because it indicates efficiency and resilience to rising costs. Compare companies within the same industry, not software firms with supermarkets. Warning sign: persistent margin compression despite higher sales.

3. Free cash flow

Broadly, cash from operations minus capital expenditures. Cash matters because companies use it to repay debt, reinvest, or return money to shareholders. Accounting profits can rise even when cash is tied up in receivables, inventory, or equipment. Warning sign: consistently negative free cash flow alongside rising reported earnings, although investment-heavy growth firms may have legitimate reasons.

4. Net debt / EBITDA

Compares financial debt minus cash with an approximate measure of operating earnings before interest, taxes, depreciation, and amortization. Net debt of 300 million against EBITDA of 100 million equals 3 times. The metric helps assess leverage, but acceptable levels vary by industry and business stability. Also check debt maturities, interest rates, and interest coverage. Warning sign: leverage rising as operating earnings fall.

5. Stock valuation

Even an excellent business can be a poor investment at an excessive price. Price-to-earnings (P/E) compares the share price with annual earnings per share; a P/E of 25 means paying 25 units of price for one unit of annual earnings, without guaranteeing returns. Compare valuation with peers, the company’s history, and realistic growth expectations. Supplement earnings multiples with cash-flow measures when needed. Warning sign: a price that assumes near-perfect execution.

Putting the metrics together

Two companies may both grow sales by 20%, yet have very different risk profiles. One may preserve margins, produce cash, and maintain manageable debt, while the other loses profitability and relies on borrowing. Read original financial statements and assess trends across multiple periods.
