If you're unfamiliar with the term "dark pool," don't worry - you're not alone. Dark pools are largely opaque institutional trading markets that are often shrouded in mystery, but they can have a huge impact on the respective markets they operate in. Put simply, dark pools are legal private alternative trading systems (ATS) called dark pools created for institutional investors to trade large transactions of equities, bonds, and foreign currencies outside of public exchanges.

Dark pool trading sites have become increasingly popular over the years, with trillions of dollars in stocks trades occurring daily. However, their existence raises some frequently asked questions (FAQs): how do dark pools work? How do they affect individual investors? And why should you care about them as part of your investment portfolio? In this article, we'll dive deeper into what exactly a dark pool is and why it's important for investors to understand their impact on institutional trading.

Definition and Examples of a Dark Pool

Dark pools are digital private markets that offer specific trading methods for institutional investors such as pension funds, mutual funds, banks, corporations, sovereign wealth, hedge and private equity funds to trade large blocks of shares without revealing their intentions or market impact. These alternative trading systems (ATS), private trading networks or alternative trading networks broadly work to match buyers and sellers at prices that may differ from prevailing exchange prices.

Dark pools offer several advantages over traditional limit order books. They allow institutional traders to execute trades based on time priority rather than price priority, which can minimize market impact and reduce transaction costs. In April 2021, dark pools executed approximately 16% of all US equity trades according to the institutional brokerage firm Rosenblatt Securities.

However, there are also concerns about the lack of transparency in these private markets. Critics argue that dark pools can lead to unfair advantages for certain traders and potentially harm overall market integrity. As a result, regulators have implemented rules requiring increased disclosure from ATS operators and limiting the amount of trading done off-exchange.


Note: Dark pools are a practice of dark pool trading that offers important benefits for market participants. By minimizing information leakage, it protects fund orders and funds trading intentions. According to an Investment Company Institute (ICI) spokesperson, email protecting confidential trading information reduces fund trading costs and can result in greater returns. On the flip side, large volume trading in open markets don't necessarily reflect shares accurately, which is where dark pools come in handy.

The Mystery Behind Dark Pools: Revealed

Chiefly, dark pools exist to offer large-scale investors the confidentiality they need when trading in substantial quantities. The Icahn Lift named after legendary investor Carl Icahn is a perfect example of this. It refers to the rise he's accountable for in the stock price of a company once he announces his interest in it. With such big players involved, one-man bull markets are created that can significantly impact a company's stock price.

Dark pools are used exclusively by institutional investors who have the capability to shift assets worth billions of dollars without causing too much market disruption. However, there's a catch; this way of trading risks creating price swings due to the lack of transparency on public exchanges. Although this may seem like a bad thing, it can potentially prevent takeover bids by making it more difficult for buyers to begin buying shares and thus sending prices spiraling.

The good news is that there are benefits to using dark pools, such as enabling companies to carry out good-faith share buybacks without tipping off other investors and causing prices on public exchanges to spiral pushing expenses and potentially debt higher. Additionally, dark pools provide an alternative to public exchanges acting as central marketplaces for investors looking to trade large blocks anonymously while keeping things quiet, avoiding spiraling prices caused by public exchange volume.

Discover the Fascinating Story of Dark Pool Creation!

Dark pools began in 1979 when traders wanted lower execution costs for large trades that could move markets. As a result, dark pools emerged as a place where anonymous orders could be placed without being publicly displayed. In 2007, an Instinet trading platform called INET allowed investors to trade after hours cross-border and across multiple markets.

Regulatory change took place in 2015 when the US Securities and Exchange Commission (SEC) made it mandatory for dark pools to disclose their trading technology and market volatility. The ITG's POSIT platform was one of the first to comply with these new regulations.

The story of dark pool creation is fascinating because it shows how traders were able to adapt to changing market conditions and use technology to execute trades more efficiently. Today, dark pools continue to be an important part of the financial landscape, allowing investors to trade large blocks of stock without affecting market prices.
