United States Securities and Exchange Commission

The United States Securities and Exchange Commission (SEC) is an independent agency of the United States federal government, created in the aftermath of the Wall Street crash of 1929. Its primary purpose is to enforce laws against market manipulation.

Created by Section 4 of the Securities Exchange Act of 1934 (now codified as 15 U.S.C. § 78d and commonly referred to as the Exchange Act or the 1934 Act), the SEC enforces the Securities Act of 1933, the Trust Indenture Act of 1939, the Investment Company Act of 1940, the Investment Advisers Act of 1940, and the Sarbanes–Oxley Act of 2002, among other statutes.
