FINRA, the Financial Industry Regulatory Authority, is a self-regulatory organization (SRO) and an independent regulator. The reading states that it describes itself as “the largest independent regulator for all securities firms doing business in the United States. Our chief role is to protect investors by maintaining the fairness of the US capital markets.” FINRA oversees over 4,000 brokerage firms, 160,000 branch offices and 629,000 registered securities representatives. FINRA has, as noted by the reading, “a degree of official sanction but is not a government agency per se.” FINRA is referred to specifically in the reading as an SRO.
