The Securities Act of 1933 is a U.S. federal law designed to ensure transparency in the financial markets. It requires companies to provide detailed information about their securities when they are offered for sale, helping investors make informed decisions. The act aims to prevent fraud and misrepresentation in the sale of securities. The Securities and Exchange Commission (SEC) is the regulatory body responsible for enforcing the provisions of the Securities Act. By requiring registration of securities and mandating disclosures, the act promotes fair practices and protects investors from potential risks associated with investing in new securities.
