Misuse of Information
MAM-3.10.7
Pump and Dump: This practice involves taking a long position in a security and then undertaking further buying activity and/or disseminating misleading positive information about the security with a view to increasing the price of the security. Other market participants are mislead by the resulting effect on price and are attracted into purchasing the security. The manipulator then sells out at the inflated price. Pump and dump is a scheme that attempts to boost the price of a stock through brokers recommendations, internet forums, or cold calling based on false, misleading or greatly exaggerated statements, and the perpetrators of this scheme, who already have an established position in the company's stock, sell their positions after the hype has led to a higher share price.

Trash and Cash: Trash and cash (or "slur and slurp") is the opposite of pump and dump. A party will take a short position in a security; undertake further selling activity and/or spread misleading negative information about the security with the purpose of driving down its price. The manipulator then closes their position after the price has fallen.

Influencing Market Price without Controlling the Available Supply or Demand: An individual may not control the supply of a security or the asset underlying a derivative contract, but may use various other means to manipulate the price, such as disseminating false information about the relevant company or taking advantage of a congested market. False information about the company or the derivative or cash market, which influences the price of the company's shares or of the asset underlying a derivative contract may be disseminated in publicly filed financial statements, press releases, or through some other medium.

Boiler Room Sales: Boiler rooms use banks of telephones to make cold calls to as many potential investors as possible using high-pressure selling techniques to persuade investors to purchase "house stocks"- stocks that the firm buys or sells as a market maker or has in its inventory. Boiler room operators typically sell worthless shares or thinly traded stocks of "microcap" or "small cap" companies.
