The SEC oversees the activities of broker-dealers, investment companies, investment advisers, clearing agencies, transfer agents, credit risk rating agencies and stock exchanges. In addition, the commission oversees organizations such as the Financial Industry Regulatory Authority, the Municipal Securities Rulemaking Board and the Public Company Accounting Oversight Board.
The agency's jurisdiction was further expanded in 2010 with the passage of the Dodd-Frank Act to include, among other things, municipal councilors.
