SEC: U.S. Securities and Exchange Commission

What Is the SEC?

The U.S. Securities and Exchange Commission (SEC) is an independent federal regulatory agency created by the Securities Exchange Act of 1934 in the wake of the 1929 stock market crash. Its founding mission, still in force today, is to protect investors, maintain fair, orderly, and efficient markets, and facilitate capital formation.

The SEC is led by five commissioners appointed by the President and confirmed by the Senate. No more than three commissioners may belong to the same political party, providing a degree of bipartisan balance. The agency is headquartered in Washington, D.C., and operates 11 regional offices across the country.

The SEC does not insure investments or guarantee returns. Its role is disclosure and oversight: ensuring that investors have access to accurate, complete, and timely information, and that the markets in which they trade operate fairly.

Jurisdiction and Scope

The SEC's jurisdiction covers the full spectrum of US securities markets. Key regulated entities include:

• Public companies: Any company whose securities are offered to the public or listed on a national exchange must register with the SEC and file periodic disclosures, including annual reports (Form 10-K), quarterly reports (Form 10-Q), and current reports (Form 8-K) for material events.
• Broker-dealers: Firms that buy and sell securities on behalf of customers or for their own accounts must register with the SEC and are also overseen by FINRA, a self-regulatory organization the SEC supervises.
• Investment advisers: Advisers managing $110 million or more in client assets must register with the SEC under the Investment Advisers Act of 1940. Those below that threshold typically register with state regulators.
• Investment companies: Mutual funds, closed-end funds, and exchange-traded funds (ETFs) register under the Investment Company Act of 1940 and must disclose their holdings, fees, and investment strategies.
• Securities exchanges and clearing agencies: National exchanges such as NYSE and Nasdaq, as well as clearinghouses like DTCC subsidiaries, must register with and report to the SEC.

The SEC also has jurisdiction over credit rating agencies (nationally recognized statistical rating organizations, or NRSROs), transfer agents, and municipal securities dealers, among others.

Key Laws and Rules

The SEC administers and enforces a body of federal securities law that has grown substantially since 1934. The foundational statutes are:

• Securities Act of 1933: Requires registration of public securities offerings and full material disclosure to prospective investors. Prohibits fraud in the offer or sale of securities.
• Securities Exchange Act of 1934: Created the SEC, requires ongoing periodic reporting by public companies, and regulates secondary market trading, broker-dealers, and exchanges.
• Investment Advisers Act of 1940: Requires registration of investment advisers and establishes fiduciary duties they owe to clients.
• Investment Company Act of 1940: Governs the structure and operations of mutual funds and other pooled investment vehicles.
• Dodd-Frank Wall Street Reform and Consumer Protection Act (2010): Expanded the SEC's oversight of over-the-counter derivatives, established the whistleblower program, and created the Office of Credit Ratings.
• JOBS Act (2012): Eased securities registration requirements for emerging growth companies and created new crowdfunding exemptions.

Key rules with direct investor impact include Regulation Best Interest (Reg BI), which requires broker-dealers to act in clients' best interests when making recommendations, and Regulation FD, which prohibits selective disclosure of material nonpublic information by public companies.

Tools for Investors

The SEC maintains several free public resources that individual investors can use directly:

• EDGAR (Electronic Data Gathering, Analysis, and Retrieval): The SEC's online filing database at sec.gov/edgar contains virtually every document a public company, fund, or registered adviser has filed with the SEC. Annual reports, proxy statements, insider trading filings (Forms 3, 4, and 5), and prospectuses are all searchable and free.
• Investor.gov: The SEC's investor education website offers plain-language guides on investment products, scam warnings, compound interest calculators, and background-check tools for brokers and advisers.
• Investment Adviser Public Disclosure (IAPD): A searchable database of SEC-registered investment advisers and their disclosure documents (Form ADV), accessible through investor.gov.
• Investor Alerts and Bulletins: The SEC's Office of Investor Education and Advocacy publishes timely warnings about investment scams, pump-and-dump schemes, and emerging risks in new asset classes including crypto.

BrokerCheck, operated by FINRA under SEC oversight, allows investors to look up the registration status and disciplinary history of any registered broker or brokerage firm.

Enforcement and Complaints

The SEC's Division of Enforcement investigates potential violations of securities law and brings civil enforcement actions in federal court or before administrative law judges. Common enforcement actions involve insider trading, accounting fraud, market manipulation, unregistered securities offerings, and Ponzi schemes.

In a typical year the SEC brings hundreds of enforcement actions and distributes hundreds of millions of dollars in disgorgement and penalties to harmed investors through its Fair Fund program.

Individual investors can report potential securities fraud or violations through the SEC's online Tips, Complaints, and Referrals (TCR) system at sec.gov/tcr. Reports can be submitted anonymously, though anonymous reporters who seek a whistleblower award must be represented by an attorney.

The SEC Whistleblower Program, created by Dodd-Frank, awards eligible individuals 10 to 30 percent of monetary sanctions exceeding $1 million collected in actions based on their original information. The program has paid over $2 billion in awards to more than 300 individuals since its inception.

For issues with a broker or brokerage firm specifically, FINRA's dispute resolution and arbitration services often provide a faster path to recovery than SEC enforcement, which focuses on systemic violations rather than individual customer disputes.
