The U.S. Securities and Exchange Commission (SEC) is a federal agency responsible for regulating the securities industry in the United States. Its main goal is to protect investors, maintain fair and efficient markets, and facilitate capital formation. The SEC enforces securities laws and oversees the activities of stock exchanges, brokers, and investment advisors. Established in 1934, the SEC plays a crucial role in ensuring transparency in financial reporting and preventing fraud. It requires publicly traded companies to disclose important financial information, helping investors make informed decisions. The SEC also investigates violations of securities laws and can impose penalties on those who break the rules.
