Unlike traditional stock exchanges, dark pools do not publicly display quotes or order book information, making it difficult for outsiders to see what trades are taking place.
Despite being termed a “dark pool”, these exchanges are legal and are regulated by the Security and Exchange Commission.
Types of dark pool
- Broker-Dealer-Owned: This type of dark pool is owned and operated by a broker-dealer or financial institution. They are typically designed to offer trading services exclusively to the broker-dealer’s clients.
- Agency Broker or Exchange-Owned: This type of dark pool is owned and operated by a brokerage firm or stock exchange. They offer trading services to a wider range of market participants and primarily serve as agents in the market.
- Electronic Market Maker: This is operated by an electronic market maker or liquidity provider. These dark pools use automated trading algorithms to match buy and sell orders. They are run by independent operators and act as principals in the market.
Advantages of dark pools
- Reducing Market Impact: Institutional investors can execute large trades without causing significant price movements in the market.
- Increasing Privacy: Dark pools can provide a high degree of privacy and confidentiality for institutional investors who may be trading sensitive or proprietary information.
- Improving Execution Quality: Dark pools can offer improved execution quality by providing access to a wider range of liquidity and reducing the impact of market volatility.
- Minimizing Trading Costs: It helps to minimize trading costs by reducing the need for expensive algorithmic trading strategies or high-frequency trading.
- Providing Flexibility: Institutional investors enjoy greater flexibility as they can customize their trading strategies and control the timing and execution of their trades.
Disadvantages of dark pool
- Lack of Transparency: Dark pools operate outside of traditional exchange trading, and therefore may lack the same level of transparency as public markets.
- Potential for Market Manipulation: The lack of transparency in dark pools can also make them more vulnerable to market manipulation.
- Conflicts of Interest: Dark pools may be operated by financial institutions that also have a vested interest in the securities being traded. This can create potential conflicts of interest that could impact the execution quality of trades.
- Limited Regulation: Dark pools are subject to less regulatory oversight than traditional exchanges, making them more vulnerable to financial fraud.
- Limited Participation: While dark pools can offer access to a wider range of liquidity, they may also have limited participation. This can make it more difficult for investors to find counterparties for their trades, particularly in less liquid markets.
Key point
A dark pool is a type of alternative trading system that gives investors a platform to trade shares without public attention.
Dark pools have some advantages but the lack of transparency can manipulate the market.
