Dark trading: what is it and how does it affect financial markets?

apsuser June 3, 2023 0 Comments

Dark pools, otherwise known as Alternative Trading Systems (ATS), are legal private securities marketplaces. In a dark pool trading system, investors place buy and dark pool finance sell orders without disclosing either the price of their trade or the number of shares. Dark pools emerged in the 1980s when the Securities and Exchange Commission (SEC) allowed brokers to transact large blocks of shares.

No exchange fees and better pricing

Detractors argue that the lack of transparency damages asset pricing https://www.xcritical.com/ in financial markets, while advocates claim that it expands access to those markets. These dark pools only generally have the bigger players involved which means that their orders can more favorably be matched by pool operators. Essentially, there is a better chance that the crossing orders at the midpoint will result in better bid ask prices for both the buyer and the seller in this equation. Standard exchanges will charge fees for block trades which can amount to pretty significant fees over a long period of time. Dark pools do not charge exchange fees on executed trades which means that you cut out these costs. Orders crossed at the midpoint of the bid-ask spread will also greatly reduce the costs incurred from the spread itself.

Understanding Dark Pool Liquidity

The story goes that Icahn can influence the price of a stock just by purchasing it. The “lift” comes when other investors see Icahn’s interest and jump in, causing the stock price to rise. Examples of agency broker dark pools include Instinet, Liquidnet, and ITG Posit, while exchange-owned dark pools include those offered by BATS Trading and NYSE Euronext. These dark pools are set up by large broker-dealers for their clients and may also include their own proprietary traders. These dark pools derive their own prices from order flow, so there is an element of price discovery. This dynamic changes once volatility in the exchange exceeds the maximum level needed for informed traders to avoid the dark pool.

When larger firms execute large-scale block trades on the public markets, they can impact the market value of stocks to a significant degree. The transparency that dark pools provide help to reduce price volatility in the market. This means that dark pools have far less impact on stock market movements than public exchanges. To avoid the transparency of public exchanges and ensure liquidity for large block trades, several of the investment banks established private exchanges, which came to be known as dark pools.

What Is a Dark Pool in Trading?

The institutional seller has a better chance of finding a buyer for the full share block in a dark pool since it is a forum dedicated to large investors. The possibility of price improvement also exists if the mid-point of the quoted bid and ask price is used for the transaction. With options two and three, the risk of a decline in the period while the investor was waiting to sell the remaining shares was also significant. In 2018, the EU implemented a provision that imposes what is called a double volume cap (DVC) of 8% on stock-level volumes executed in dark venues over any 12-month period. Dark pools enable an opaque form of trading in financial assets that has raised concerns among investors, brokers, exchanges and regulators.

Dark pools allow investors to trade without any public exposure until after the trade is executed and cleared. It is favorable for investors, such as hedge funds and activist investors, who do not want the public to know which positions they are taking. There’s no practical chance that an average retail trader will shift the market.

There will be a need for the market player to have separate accounts with the various liquidity providers. At this point, it might not be wholly clear where the advantages lie with using dark pools.

What are the controversies around dark pools?

The fragmentation of electronic trading platforms has allowed dark pools to be created, and they are normally accessed through crossing networks or directly among market participants via private contractual arrangements. Generally, dark pools are not available to the public, but in some cases, they may be accessed indirectly by retail investors and traders via retail brokers. The primary advantage of dark pool trading is that institutional investors making large trades can do so without exposure while finding buyers and sellers. If it were public knowledge, for example, that an investment bank was trying to sell 500,000 shares of a security, the security would almost certainly have decreased in value by the time the bank found buyers for all of their shares. Devaluation has become an increasingly likely risk, and electronic trading platforms are causing prices to respond much more quickly to market pressures.

As discussed, if a mutual fund manager, for example, wants to sell a million shares of a given stock because it’s underperforming or no longer fits their strategy, they’d need to use a floor trader to unload the position on a public exchange. Selling all those shares could impact the price they get, driving down the VWAP (volume weighted average price) of the total sale. The history of dark pools in the trading world starts in the 1980s, following changes at the Securities and Exchange Commission (SEC) which effectively allowed brokers to make trades in large share blocks. Later, in the mid-2000s, further SEC changes that were meant to cut trading costs and increase market competition led to an increase in dark pool trading.

Dark pool trading is not inherently unsafe but as a smaller retail investor, there are a number of factors for you to consider. As we mentioned earlier, larger trading firms can execute pinging tactics which could impact the pricing of the shares you are trying to buy. While there may have been calls for more regulation of dark pools of late, there is still a chance that you fall prey to unethical trading practices that are essentially conflicts of interest with larger trading firms. Since the details of the trades are not available to the public, it can be challenging to assess the impact of dark pool trading on the broader market. By matching buyers and sellers privately and executing the trade outside the public market, dark pools prevent other market participants from reacting to the trade and driving up or down the price.

The popularity of dark pools also stems from their specific trade execution formats and specialties. Some operate on a continuous trading basis throughout the day, while others are block trading-cross platforms. Some operate as non-displayed limit order books, while others execute orders at the exchange midpoint, and others that quickly accept or reject incoming orders. The dark pool gets its name because details of these trades are concealed from the public until after they are executed; these transactions are obscure like dark, murky water. Electronic trading’s become more prominent nowadays, and therefore, exchanges can be set up purely in a digital form.

Dark pools are sometimes cast in an unfavorable light but they serve a purpose by allowing large trades to proceed without affecting the wider market. However, their lack of transparency makes them vulnerable to potential conflicts of interest by their owners and predatory trading practices by some high-frequency traders. Eventually, HFT became so pervasive that it grew increasingly difficult to execute large trades through a single exchange. Because large HFT orders had to be spread among multiple exchanges, it alerted trading competitors who could then get in front of the order and snatch up the inventory, driving up share prices. A cross trade is the matching of buy and sell orders outside of an exchange. Usually, brokers will execute a cross, which is a match of a buy and sell order for the same asset from different clients, without sending the buy and sell orders to the exchange.

Investors would immediately know about the takeover or share buyback in progress and would trade accordingly. On a dark pool, these parties can keep things quiet a little longer and hopefully avoid spiraling prices. Chiefly, dark pools exist for large scale investors that don’t want to influence the market through their trades. The influence they could potentially have on the market is often known as the Icahn Lift, named after legendary investor Carl Icahn.
