Pump and dump (P&D) is a form of securities fraud that involves artificially inflating the price of an owned stock through false and misleading positive statements (pump), in order to sell the cheaply purchased stock at a higher price (dump). Once the operators of the scheme "dump" (sell) their overvalued shares, the price falls and investors lose their money. 

Pump-and-dump schemes may take place on the Internet  ... Often the stock promoter will claim to have "inside" information about impending news. 

Promoters may also post messages in online chat groups or internet forums, urging readers to buy the stock quickly.

Fraudsters frequently use this ploy with small, thinly traded companies—known as "penny stocks"

A more modern spin on this attack is known as hack, pump and dump.^[6] In this form, a person purchases penny stocks 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.
