Pump and Dump - Pump and Dump Scenarios

Pump and Dump Scenarios

Pump and dump schemes may take place on the Internet using an e-mail spam campaign, through media channels via a fake press release, or through telemarketing from "boiler room" brokerage houses (for example, see Boiler Room). Often the stock promoter will claim to have "inside" information about impending news. Newsletters that purport to offer unbiased recommendations then tout the company as a "hot" stock. Messages in chat rooms and email spam urge readers to buy the stock quickly.

Unwitting investors then purchase the stock, creating high demand and raising the price. This seemingly "real" rise in prices can entice more people to believe the hype and to buy shares as well. When the people behind the scheme sell their shares and stop promoting the stock, the price plummets, and other investors are left holding stock that is worth significantly less than what they paid for it.

Fraudsters frequently use this ploy with small, thinly traded companies—known as "penny stocks," generally traded over-the-counter (in the United States, this would mean markets such as the OTC Bulletin Board or the Pink Sheets), rather than markets such as the New York Stock Exchange or NASDAQ—because it is easier to manipulate a stock when there is little or no independent information available about the company. The same principle applies in the United Kingdom, where target companies are typically small companies on the AIM or OFEX.

A more modern spin on this attack is known as hack, pump and dump. In this form a person purchases penny stocks in advance and then uses compromised brokerage accounts to purchase large quantities of that stock. The net result is a price increase, which is often pushed further by day traders seeing a quick advance in a stock. The holder of the stock then sells his stock at a premium.
