Public stock exchanges like the New York Stock Exchange and the Nasdaq are heavily regulated and monitored by the SEC . In contrast, dark pools are subject to very little regulation and oversight by any governing organizations. This is why they are also called dark pools of liquidity.  An institutional investor has a greater chance of selling a large block of a security within a dark pool since its already restricted to large investors. Dark pool investing can save institutional investors money since they arent managed by a large public exchange and therefore avoid exchange fees. Also, the intentions of their trades aren't public until after the trades are executed, which can also offer a price benefit for an institutional investor. Dark pools are legal trading exchanges that are kept private. They might also be called alternative trading systems (ATS ) or private trading networks. Investopedia reported that as of February 2020, over 50 dark pools were registered with the SEC, falling into three different categories.
