Company Statistics Explained: Market Cap, EPS and P/E

Educational guide · Updated October 9, 2026

The share price tells you what one share trades for. It does not tell you how large the company is, how much it earns or whether its shares are attractively valued. Company statistics help answer different questions, and they need comparable dates and accounting definitions.

Market capitalization: size, not cash

Market capitalization is share price multiplied by outstanding shares. A hypothetical company with 10 million shares priced at 20 has a market cap of 200 million in that currency. Market cap is not revenue or money in the bank; it also differs from enterprise value, which incorporates debt and cash.

Earnings per share

EPS expresses earnings per share under a defined calculation. Basic and diluted EPS can differ, as can reported and adjusted results. Check whether a displayed value covers the latest fiscal year, a quarter or the trailing twelve months.

P/E needs a comparison

The price-to-earnings ratio divides share price by earnings per share. A low P/E can reflect lower growth expectations or business risk; a high P/E can reflect stronger expectations that may not materialize. When earnings are negative or close to zero, the ratio can be unavailable or misleading.

Use statistics as a starting point

Compare companies within an appropriate business context and use consistent periods. Review the balance sheet, cash flow and primary company filings. A widget’s missing value means unavailable data, not a zero-valued business metric.
