The federal securities laws seek to prohibit fraud manipulation and other abuses associated with securities transactions. The most prominent of these prohibitions is found in Section l0(b) of the Securities Exchange Act of 1934 (the "34 Act") and Rule l0b-5 promulgated thereunder by the Securities Exchange Commission ("SEC"). There are, however, additional anti-fraud provisions in others of the so-called federal securities laws, including the Securities Act 1933 (the "33 Act") and the Investment Advisers Act of 1940 (the "1940 Act"). This chapter will focus principally upon Section l0(b) of the 34 Act, but it will also more briefly describe the anti-fraud provisions in the 33 and 1940 Acts.
