Common Forms of Market Manipulation

Market manipulation occurs when individuals or companies:

  • distort prices or trades to create a false demand for a security;
  • make stock trades based on inside information that is not publicly available (insider trading);
  • improperly limit the number of publicly available shares in a stock; or
  • spread false or misleading information about a company (often through corporate disclosures).

Laws Against Market Manipulation

Market manipulation is illegal in the United States under both securities and antitrust laws.

Securities Laws

Securities laws and related SEC rules broadly prohibit fraud in the purchase and sale of securities, and the Securities Exchange Act of 1934, Section 9, specifically makes it unlawful to manipulate security prices.


Antitrust Laws

Antitrust Laws such as the Sherman Act and the Commodity Exchange Act.

Violations of these laws can result in government investigations & disciplinary actions, as well as criminal charges and civil lawsuits by investors and others who were harmed.
