Securities regulation refers to the laws and rules that govern the issuance and trading of financial instruments known as securities, which include stocks and bonds. These regulations aim to protect investors from fraud, ensure transparency in the markets, and maintain fair trading practices. In the United States, the primary regulatory body is the Securities and Exchange Commission (SEC). The SEC enforces securities laws, requiring companies to disclose important financial information to the public. This helps investors make informed decisions. Additionally, securities regulation includes rules for brokers and dealers to ensure they act in the best interests of their clients, promoting trust in the financial system.
