What is a "pump and dump" stock scam?
assistant
A "pump and dump" stock scam is a stock market manipulation scheme in which a group of people buy a large number of shares of a stock, usually at a low price, and then artificially inflate the price of the stock by spreading false rumors about the company. The group then sells their shares at the inflated price, making a profit on the difference between the original price and the inflated price.
