Circular trading is a type of securities fraud that can take place in stock markets, causing price manipulation and often related to pump and dump schemes. Circular trading occurs when identical buy and sell orders are entered at the same time with the same number of shares and the same price. As a result, there is no change in ownership of shares, but there is the appearance of an increased trade volume.
