Pump and dump

The "night singer of shares" sold stock on the streets during the South Sea Bubble. Amsterdam, 1720.

"Pump and dump" (P&D) is a form of microcap stock fraud that involves artificially inflating the price of an owned stock through false and misleading positive statements, in order to sell the cheaply purchased stock at a higher price. Once the operators of the scheme "dump" sell their overvalued shares, the price falls and investors lose their money. Stocks that are the subject of pump and dump schemes are sometimes called "chop stocks".[1]

While fraudsters in the past relied on cold calls, the Internet now offers a cheaper and easier way of reaching large numbers of potential investors.[1]

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).[2] Often the stock promoter will claim to have "inside" information about impending news.[3] Newsletters may purport to offer unbiased recommendations, then tout a company as a "hot" stock, for their own benefit. Promoters may also post messages in chat rooms or stock message boards such as ADVFN, urging readers to buy the stock quickly.[1]

If a promoter's campaign to "pump" a stock is successful, it will entice unwitting investors to purchase shares of the target company. The increased demand, price, and trading volume of the stock may convince more people to believe the hype, and to buy shares as well. When the promoters behind the scheme sell (dump) 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 (NYSE) or NASDAQ—because it is easier to manipulate a stock when there is little or no independent information available about the company.[4] 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.[5] 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 their stock at a premium.[6]

Specific examples

Stratton Oakmont

See Stratton Oakmont article.

Jonathan Lebed

During the dot-com era, when stock-market fever was at its height and many people spent significant amounts of time on stock Internet message boards, a 15-year-old named Jonathan Lebed showed how easy it was to use the Internet to run a successful pump and dump. Lebed bought penny stocks and then promoted them on message boards, pointing at the price increase. When other investors bought the stock, Lebed sold his for a profit, leaving the other investors holding the bag. He came to the attention of the U.S. Securities and Exchange Commission (SEC), which filed a civil suit against him alleging security manipulation. Lebed settled the charges by paying a fraction of his total gains. He neither admitted nor denied wrongdoing, but promised not to manipulate securities in the future.[7]


As late as April 2001, before the company's collapse, Enron executives participated in an elaborate scheme of pump and dump,[8] in addition to other illegal practices that fooled even the most experienced analysts on Wall Street. Studies of the anonymous messages posted on the Yahoo board dedicated to Enron revealed predictive messages that the company was basically a house of cards, and that investors should bail out while the stock was good.[9] After Enron falsely reported profits which inflated the stock price, they covered the real numbers by using questionable accounting practices. 29 Enron executives sold overvalued stock for more than a billion dollars before the company went bankrupt.[10]

Park Financial Group

In April 2007, the U.S. SEC brought charges against Park Financial Group as a result of an investigation into a pump and dump scheme during 2002-2003 of the Pink Sheet listed stock of Spear & Jackson Inc.[11]

Langbar International

Started as Crown Corporation, Langbar was the biggest pump and dump fraud on the Alternative Investment Market, part of the London Stock Exchange. The company was at one point valued greater than $1 billion, based on supposed bank deposits in Brazil which did not exist. None of the chief conspirators were convicted, although their whereabouts are known. A patsy who made a negligent false statement about the assets was convicted and banned from being a director.[12] The investors who lost as much as £100 million sued one of the fraudsters and recovered £30 million.[13]


A very well known Spanish empapelor, having pump & dumped many stocks, including the world famous scam company Gowex, as well as cryptocurrencies, such as Bitcoin, Litecoin and Ethereum.[14]

Pump and dump scam

Pump and dump stock scams are prevalent in spam, accounting for about 15% of spam e-mail messages. A survey of 75,000 unsolicited emails sent between January 2004 and July 2005 concluded that spammers could make an average return of 4.29% by using this method, while recipients who act on the spam message typically lose close to 5.5% of their investment within two days.[15] A study by Böhme and Holz[16] shows a similar effect. Stocks targeted by spam are almost always penny stocks, selling for less than $5 per share, not traded on major exchanges, are thinly traded, and are difficult or impossible to sell short. Spammers acquire stock before sending the messages, and sell the day the message is sent.[17]

Pump and dump differs from many other forms of spam (such as advance fee fraud emails and lottery scam messages) in that it does not require the recipient to contact the spammer to collect supposed "winnings," or to transfer money from supposed bank accounts. This makes tracking the source of pump and dump spam difficult, and has also given rise to "minimalist" spam consisting of a small untraceable image file containing a picture of a stock symbol.

Short and distort

A variant of the pump and dump scam, the "short and distort" works in the opposite manner. Instead of first buying the stock, and then artificially raising its price before selling, in a "short and distort" the scammer first short-sells the stock, and then artificially lowers the price, using the same techniques as the pump and dump but using criticism or negative predictions regarding the stock. The scammer then covers his short position when he buys back the stock at a lower price.[18]


One method of regulating and restricting pump and dump manipulators is to target the category of stocks most often associated with this scheme. To that end, penny stocks have been the target of heightened enforcement efforts. In the United States, regulators have defined a U.S. District Court,[23] and the statute became the template for laws enacted in other states. Shortly thereafter, both FINRA and the SEC enacted comprehensive revisions of their penny stock regulations. These regulations proved effective in either closing or greatly restricting broker/dealers, such as Blinder, Robinson & Company, which specialized in the penny stocks sector. Meyer Blinder was jailed for securities fraud in 1992, after the collapse of his firm.[24] However, sanctions under these specific regulations lack an effective means to address pump and dump schemes perpetrated by unregistered groups and individuals.
