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 offer them to the public. This helps investors make informed decisions and reduces the risk of fraud. The Act mandates that companies file a registration statement with the Securities and Exchange Commission (SEC) before selling securities. This statement includes financial statements and other essential data. By enforcing these requirements, the Act aims to protect investors and promote fair practices in the securities industry.
