About the figures

Each stock represents one issuer, counted once. Companies use our applied industry classification; sub-industries use SIC descriptions. A SIC may appear in more than one industry.

Market cap is our calculated company market capitalization. Revenue and net income use USD figures from SEC filings. TTM uses the latest annual value plus current year-to-date results minus the corresponding prior-year results, or the latest complete fiscal year when it is the latest available endpoint. Net income uses reported net income or profit/loss. Available TTM reporting periods end on 2026-06-30. Reporting periods can differ across companies.

Totals sum available USD figures only. The stock counts below each total show coverage for that metric. A dash means no figure is available; missing values are never counted as zero. Totals with partial coverage do not represent the complete sub-industry.
