The U.S. Securities and Exchange Commission (SEC) is an independent federal government regulatory agency of the United States, established by Section 4 of the Securities Exchange Act of 1934. Its creation was a direct response to the financial abuses that contributed to the 1929 stock market crash and the subsequent Great Depression, aiming to restore public confidence in the U.S. markets. The problem it solved was the lack of federal oversight and the inadequacy of state-level "blue sky laws" to prevent widespread fraud and ensure transparency in securities trading across state lines.
The SEC's core mission is to protect investors, maintain fair, orderly, and efficient markets, and facilitate capital formation. It works by enforcing federal securities laws, primarily the Securities Act of 1933 and the Securities Exchange Act of 1934. The 1933 Act requires that investors receive significant financial information concerning securities offered for public sale and prohibits fraud in their sale. The 1934 Act mandates periodic reporting of information by companies with publicly traded securities and regulates the conduct of market participants, exchanges, and self-regulatory organizations (SROs) like the Financial Industry Regulatory Authority (FINRA). Companies with over $10 million in assets and more than 500 owners must file annual and periodic reports, which are made public through the SEC's EDGAR database.
The SEC connects to other major legislation, including the Sarbanes-Oxley Act of 2002, which enhanced corporate responsibility and financial disclosures following corporate fraud scandals. Recently, the SEC has proposed significant changes, such as amendments to simplify public company reporting requirements and expand eligibility for shelf offerings, which would be the most significant overhaul of the registered offering framework in over 20 years. Another proposed rule change would permit eligible companies to elect to file a single semiannual report on a new Form 10-S instead of three quarterly reports on Form 10-Q, though quarterly reporting would remain the default. These proposals aim to incentivize companies to go and stay public while maintaining robust investor protections.
