All Stock Exchanges and Market Infrastructure

Organized marketplaces and the infrastructure operators through which equities, derivatives and other securities are listed, traded and cleared, including the major national and regional exchanges. Belongs here: any institution whose primary function is operating a trading venue or clearing infrastructure for securities or derivatives. Does not belong here: bodies that regulate how exchanges and market participants must behave without operating a trading venue themselves, grouped under Regulatory and Standard-Setting Bodies, or agencies that rate the creditworthiness of issuers on those exchanges rather than trade their securities, grouped under Credit Rating Agencies.
