Manipulation(redirected from Joint manipulation)
Also found in: Dictionary, Thesaurus, Medical, Legal, Encyclopedia, Wikipedia.
The attempt or act to artificially change the price of a security or a market movement with the intent to make a profit. One example is wash selling, in which an investor both sells then quickly re-buys the same security, hoping to create the impression of increased trading volume, and therefore raise the price. Another is churning, in which an investor makes both buy and sell orders through different brokers to create the impression of increased interest in the security and raise the price. Manipulation can be used to both increase and decrease prices, depending on the investor's perceived needs. Manipulation is illegal under the Securities Exchange Act of 1934. See also: Antitrust, Fix.
