What is the Dark Pool?

The dark pool can be defined as private networks or private platforms that allow professional investors to trade stock on a large-scale basis without revealing too many details. Thus, a dark pool is often regarded as dark pool liquidity or dark liquidity. 

Dark pools are precisely opposite to public financial markets as it is a private platform without any attention from the media. The dark pool keeps the data private about the stock until the trade is executed. It is a favourable medium for the investors such as hedge funds and activist investors during situations when they do not want to reveal their strategy and the position they are taking. 

When the Securities and Exchange Commission (SEC) allowed brokers to trade big blocks of shares in the 1980s, dark pools arose. Electronic trading and a 2007 SEC regulation aimed at increasing competition and lowering transaction costs have sparked an increase in the number of dark pools. Because dark pools are generally hosted within a huge corporation, they can demand cheaper fees than exchanges.
