Securities fraud is the offense of deceiving investors or manipulating financial markets in connection with the purchase or sale of stocks, bonds or other securities, covering conduct such as making false or misleading statements about a company's finances or prospects, trading on material non-public information, or artificially manipulating a security's price. It is generally investigated and prosecuted in close coordination with a jurisdiction's securities regulator, which typically has its own civil enforcement powers, such as fines and trading bans, that run alongside and sometimes precede any separate criminal prosecution for the same conduct. Common recognized forms include a Ponzi or pyramid investment scheme, in which returns paid to earlier investors come from money contributed by later investors rather than from any genuine underlying investment activity, and accounting fraud, in which a company's financial statements are deliberately falsified to mislead investors and inflate its apparent value. Securities fraud is closely related to, but legally distinct from, insider trading, the narrower offense of trading on material non-public information specifically, and to the wire and mail fraud offenses whose electronic or postal communications a securities fraud scheme frequently uses to reach its victims.
Facts
Classification CodeThe broadest federal antifraud measure for securities is Rule 10b-5, promulgated under section 10(b) of the Securities Exchange Act of 1934, the statutory basis most federal securities fraud prosecutions and civil suits rely on. 1 Typical PenaltyFederal law criminalizes securities and commodities fraud under 18 U.S.C. section 1348, which provides that a violator shall be fined, imprisoned for not more than twenty five years, or both. 2 Elements of OffenseUnder United States Securities and Exchange Commission Rule 10b-5, establishing civil securities fraud liability requires proving that the defendant misrepresented a material fact, did so knowingly (referred to as scienter), that the plaintiff relied on that misrepresentation, and that the reliance caused the plaintiff's loss. 1 Notable ExampleThe largest securities fraud committed by a single individual was the Ponzi scheme run by former NASDAQ chairman Bernard Madoff, estimated to have caused up to sixty four point eight billion dollars in investor losses. 3 Jurisdiction VariationBeyond federal law, individual states also criminalize securities fraud under their own statutes; California's Corporations Code, for example, separately provides that securities fraud in that state may be punished by a fine, imprisonment, or both. 1 Classification
