Since these laws were originally enacted, Congress has amended them many times. The Holding Company Act and the Trust Indenture Act in particular have changed significantly since then. The titles listed above, including the year of original enactment, are the so-called "popular names" of these laws, and practitioners in this area reference these statutes using these popular names. When they do so, they do not generally mean the provisions of the original Acts; they mean the Acts as amended to date. When Congress amends the securities laws, those amendments have their own popular names. These acts often include provisions that state that they are amending one of the five primary laws. Other laws passed since then include Private Securities Litigation Reform Act, Sarbanes–Oxley Act, Jumpstart Our Business Startups Act, and various other :Category:United States federal securities legislation|federal securities laws. Although practitioners in this area use these popular names to refer to the federal securities laws, like many U.S. statutes these laws are generally codified in the U.S. Code, the official codification of U.S. statutory law. They are contained in Title 15 of the U.S. Code. Thus, for example, the official code citation for Section 5 of the Securities Act of 1933 is 15 U.S.C. section 77e. Not every law adopted by Congress is codified, because some are not appropriate for codification. For example, appropriations statutes are not codified. There are also extensive regulations under these laws, largely made by the SEC. One of the most famous and often used SEC rules is Rule 10b-5, which prohibits fraud in securities transactions as well as insider trading. Because interpretations under rule 10b-5 often deem silence to be fraudulent in certain circumstances, efforts to comply with Rule 10b-5 and avoid lawsuits under 10b-5 have been responsible for a large amount of corporate disclosure. The federal securities laws govern the offer and sale of securities and the trading of securities, activities of certain professionals in the industry, investment companies, tender offers, proxy statements, and generally the regulation of public companies. Public company regulation is largely a disclosure-driven regime, but it has grown in recent years to the point that it begins to dictate certain issues of corporate governance. State laws governing issuance and trading of securities are commonly referred to as blue sky laws.
History
Before the Wall Street Crash of 1929, there was little regulation of securities in the United States at the federal level. The crash spurred Congress to hold hearings, known as the Pecora Commission, after Ferdinand Pecora. After the hearings Congress passed the Securities Act of 1933 prescribing rules for the interstate sales of securities, and made it illegal to sell securities in a state without complying with that state's laws. The statute requires a publicly traded company to register with the U.S. Securities and Exchange Commission. The registration statement provides a broad range of information about the company and is a public record. The SEC does not approve or disapprove the issue of securities, but rather permits the filing statement to "become effective" if sufficient required detail is provided, including risk factors. The company can then begin selling the stock issue, usually through investment bankers. The following year, Congress passed the Securities Exchange Act of 1934, to regulate the secondary market trading of securities. Initially, the 1934 Act applied only to stock exchanges and their listed companies, as the name implies. In the late 1930s, it was amended to provide regulation of the over-the-counter market. In 1964, the Act was amended to apply to companies traded in the OTC market. Courts interpreted the laws, assembling a body of :Category:United_States_securities_case_law|United States securities case law. In 1988 the Supreme Court of the United States decided Basic Inc. v. Levinson, which allowed class action lawsuits under SEC Rule 10b-5 and the "fraud-on-the-market" theory, which resulted in an increase in securities class actions. The Private Securities Litigation Reform Act and the state model law Securities Litigation Uniform Standards Act was a response to class actions. In October 2000, the SEC issued the Regulation Fair Disclosure regulation, which required publicly traded companies to disclose material information to all investors at the same time. Reg FD helped level the playing field for all investors by helping to reduce the problem of selective disclosure. In 2010, the Dodd–Frank Wall Street Reform and Consumer Protection Act was passed to reform securities law in the wake of the financial crisis of 2007–2008.
