Sectors

Sector groupings are Tickerscape's own, derived from each company's SEC Standard Industrial Classification code — not GICS®, ICB® or any other licensed scheme, and they will disagree with those on some companies. How sectors are assigned.

Largest cities

These are cities as recorded on each company's filed address, not metropolitan areas — neighbouring municipalities are counted separately.

Data last updated 2026-09-14. This count is computed from the published headquarters dataset each time the page loads. Registered-agent addresses are excluded so incorporation services do not inflate a state, a company with two listed share classes is counted once, and companies headquartered outside the United States are counted in no state. How this count is derived.

Informational purposes only — not investment advice. Headquarters locations reflect each company's most recently recorded principal address and are approximate.
