Yes. While the Federal Securities Laws are by far the most important laws governing securities and the securities markets generally, most states also have "Blue Sky Laws" that apply to a company that wishes to sell securities to the state's residents, or to persons who wish to engage in business as a securities broker or dealer, or to give investment advice to others.
Although the focus of this section will be on the provisions of the Federal Securities Laws that impact investors, in many cases a state's laws may give the investor who loses money or is defrauded in the securities markets far greater protections than are available under Federal law. Often, when litigation is necessary, attorneys make claims under both Federal and applicable state law.
