Microcap stock fraud is a form of securities fraud involving stocks of "microcap" companies, generally defined in the United States as those with a market capitalization of under $250 million. Its prevalence has been estimated to run into the billions of dollars a year. Many microcap stocks are penny stocks, which the SEC defines as a security that trades at less than $5 per share, is not listed on a national exchange, and fails to meet other specific criteria.

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. This is most common with small-cap cryptocurrencies and very small corporations/companies, i.e. "microcaps".
