Fundamental Metrics, Explained

Last reviewed on 2026-04-27.

The fundamental data block on a ticker page packs a lot of ratios into a small space. The good news: most of them are different ways of asking three questions. Is this business profitable? How much is the market paying for that profitability? And is the balance sheet sturdy enough to keep it going? Once those three questions are clear, the dozens of ratios become a translation exercise.

The three questions, in one paragraph each

Profitability. Companies sell goods or services and incur costs. The gap between revenue and cost is profit. The relevant question is not just whether profit exists, but how much profit a business squeezes out of each dollar of sales (margin), and how much it earns relative to the capital invested in it (return on equity, return on capital).

Valuation. A share is a claim on a slice of those profits. The market is constantly putting a price on that slice. Valuation ratios — P/E, P/B, P/S, EV/EBITDA — compare the price the market is paying to some measure of what the company is producing or owns. Lower is "cheaper" in a literal arithmetic sense; whether it is cheap in a useful sense depends on why.

Balance sheet. Profitability and valuation describe the income statement and the share price. The balance sheet describes what the company owns and owes — the stock of capital it is operating from. A company with little debt and lots of cash can survive a bad year that a heavily indebted competitor cannot.

Valuation ratios

Price-to-earnings (P/E)

The most-quoted ratio in finance. Share price divided by earnings per share. A P/E of 20 means investors are paying twenty dollars for every dollar of current annual profit. Trailing P/E uses the past twelve months of earnings; forward P/E uses an estimate of the next twelve months.

P/E is useful precisely because it is a benchmark — historical averages, sector averages, and the company's own past P/E give context. It is misleading when earnings are temporarily depressed (P/E balloons) or temporarily inflated by one-off gains (P/E shrinks). The lowest P/E in a sector is often the company in the most trouble, not the best bargain.

Price-to-book (P/B)

Share price divided by book value per share — book value being roughly the net assets on the balance sheet. P/B is most informative for asset-heavy businesses such as banks, insurers and industrials, where the book value is a real number reflecting tangible assets. It is much less informative for asset-light businesses such as software and services, where most of the value sits in intangibles that the balance sheet underweights or ignores.

Price-to-sales (P/S)

Share price divided by revenue per share. Useful when a company has no earnings — early-stage growth companies, biotech, cyclicals at a trough. The drawback is obvious: a dollar of sales at one company drops a lot more to the bottom line than a dollar of sales at another.

EV/EBITDA

Enterprise value (market cap plus debt minus cash) divided by EBITDA (earnings before interest, taxes, depreciation and amortisation). The ratio that financial analysts often prefer to plain P/E because it normalises across capital structures: two companies with very different debt levels become more comparable when measured this way.

EV/EBITDA carries a famous warning: EBITDA is not cash flow, and it is not a substitute for net income. Depreciation is a real cost — assets really do wear out — and a company with high capital expenditure will look misleadingly cheap on EV/EBITDA.

Dividend yield

Annualised dividend per share divided by share price. A 4% yield on a stock means the company is paying out 4% of the share price per year as dividends. Yields move inversely with price — if the share falls, the yield rises mechanically, even though nothing about the dividend has changed. Eye-catching yields (8%, 10%, 12%) are usually the result of a falling share price and often signal a coming dividend cut, not a generous policy.

Profitability ratios

Gross, operating and net margin

Three ways to slice "profit as a percentage of revenue." Gross margin is revenue minus the direct cost of goods sold. Operating margin subtracts operating expenses (R&D, sales, marketing, general and administrative). Net margin subtracts everything left — interest, taxes, one-offs.

Gross margin says something about pricing power and the cost structure of the underlying product. Operating margin reflects how efficiently the company runs the business around that product. Net margin is what actually accrues to shareholders. A high gross margin and a low operating margin together suggest a company that has a good product but spends heavily — common in early-stage growth.

Return on equity (ROE)

Net income divided by shareholders' equity. The number that long-term investors tend to respect most: it answers how much profit the business is generating per dollar of equity capital it has been entrusted with. Sustained ROE above 15% over many years is unusual and is generally the signature of a high-quality business with a real economic moat.

The catch is leverage. ROE can be inflated by debt — borrowing to buy back shares mechanically lifts the ratio without making the business any better. Pair ROE with debt-to-equity to see whether the high return is genuine or a balance-sheet trick.

Return on assets (ROA)

Net income divided by total assets. ROA does not care how the assets are financed, so it cuts through the leverage trick that distorts ROE. It is more useful for comparing companies in capital-intensive industries (manufacturers, utilities) than for asset-light software businesses.

Balance-sheet ratios

Debt-to-equity

Total debt divided by shareholders' equity. A blunt measure of leverage. A debt-to-equity of 0.3 is conservative; 1.0 is meaningful debt; 3.0 is heavy. The "right" level depends on the industry. Real-estate companies and utilities run with high debt by design; software companies typically do not.

Current ratio

Current assets (cash, receivables, inventory) divided by current liabilities (payables, short-term debt). Roughly: can the company pay what it owes within the next year out of what it has on hand within the next year? A current ratio above 1 is the conventional baseline. A ratio above 2 means a comfortable cushion; a ratio below 1 is a warning, or, occasionally, a sign of a fast-moving working-capital model where it is normal.

Cash and short-term investments

Not a ratio, but worth checking. A company with multiple years of net cash on its balance sheet is structurally different from one that lives quarter to quarter on a credit line.

Putting it together — a worked walkthrough

Suppose two stocks both screen at a forward P/E of 14. On the surface, equally priced. Now look at the rest of the row.

Stock A: revenue growing 3% per year, gross margin 28%, ROE 9%, debt-to-equity 1.4, dividend yield 5%, P/B 1.1.

Stock B: revenue growing 12% per year, gross margin 60%, ROE 22%, debt-to-equity 0.2, no dividend, P/B 5.5.

Same P/E, different businesses. Stock A is a slow-growing, leveraged, dividend-paying mature business — a "value" candidate where the question is whether the dividend is safe and the leverage manageable. Stock B is a profitable growth business where the question is whether the 12% growth is durable. They face completely different risks. The P/E alone never says any of this. The full row does.

Common mistakes

• Comparing across very different industries. A P/E of 12 is cheap for a software company and expensive for a tobacco company. Sector context matters.
• Treating one-quarter spikes as the new normal. Trailing twelve-month figures absorb a single unusual quarter. A single-quarter P/E or margin can mislead in either direction.
• Ignoring the income statement when the balance sheet looks fine, or vice versa. A profitable business with a fragile balance sheet, or a fortress balance sheet wrapped around a deteriorating business, can both end in trouble.
• Reading metrics without the context of how the company actually makes money. The numbers are summaries of a story. Read the company profile section first; the numbers make more sense afterwards.

Where to look on tickers.info

The fundamental data block on every ticker page shows most of the metrics covered above, alongside the company profile. The screener exposes them as filters, so a reader can sort the universe by valuation, profitability or leverage. The screener guide walks through how to combine those filters into something coherent.
