'33 Act

aka Securities Act US


Securities Act of 1933 was the first major piece of U.S. federal legislation regarding the sale of securities. Prior to this legislation, the sale of securities was primarily governed by state laws aka Blue Sky laws; however, the market crash of 1929 raised some serious questions about the effectiveness of how the markets were being governed. In general, the legislation was enacted as the need for more information within and about the securities markets was acknowledged. The legislation addressed the need for better disclosure by requiring companies to register with the Securities and Exchange Commission. Registration ensures companies provide the SEC and potential investors with all relevant information by means of the prospectus and registration statement.

'34 Act

aka Exchange Act US


Securities Exchange Act of 1934 primarily regulates transactions of securities in the secondary market - that is, sales that take place after a security is initially offered by a company (the issuer).These transactions often take place between parties other than the issuer, such as trades that retail investors execute through brokerage firms.The Exchange Act operates somewhat differently from the Securities Act. To protect investors, Congress crafted a mandatory disclosure process that is designed to force companies to make public information that investors would find pertinent to making   investment decision. In addition, the Exchange Act provides for direct regulation of the markets on which securities are sold (the securities (stock) exchanges) and the participants in those markets (industry associations, brokers, and issuers).In a major step by Congress, Section 4 of the Exchange Act established the Securities and Exchange Commission (SEC), a federal agency responsible for regulating the securities markets.
