SEC Division of Trading and Markets —
Division of Trading and Markets (from November 2007)
Division of Market Regulation (1972 – November 2007)
Division of Trading and Markets (1963 – 1971)
Division of Trading and Exchanges (1948 – 1962)
Division of Trading and Exchange (1935 – 1947)

The Division of Trading and Markets assists the Commission in executing its responsibility for maintaining fair, orderly, and efficient markets. The staff of the Division provide day-to-day oversight of the major securities market participants: the securities exchanges; securities firms; self-regulatory organizations (SROs) including the Financial Industry Regulatory Authority (FInRA), the Municipal Securities Rulemaking Board (MSRB), clearing agencies that help facilitate trade settlement; transfer agents (parties that maintain records of securities owners); securities information processors; and credit rating agencies.

The Division also oversees the Securities Investor Protection Corporation (SIPC), which is a private, non-profit corporation that insures the securities and cash in the customer accounts of member brokerage firms against the failure of those firms. It is important to remember that SIPC insurance does not cover investor losses arising from market declines or fraud.

The Division's additional responsibilities include:

• carrying out the Commission's financial integrity program for broker-dealers;
• reviewing (and in some cases approving, under authority delegated from the Commission) proposed new rules and proposed changes to existing rules filed by the SROs;
• assisting the Commission in establishing rules and issuing interpretations on matters affecting the operation of the securities markets; and
• monitoring the market.
