Understanding sub-penny trading
Sub-penny trading, a practice within unseen market centers like dark pools, involves trading in increments less than a penny. Brokers and dealers engage in this practice through wholesalers, dark pools, and lit exchanges, taking advantage of opportunities to capture spreads in fractions of cents.
The sub-penny rule (SEC Rule 612)
The SEC introduced Rule 612 in 2005, preventing exchanges governed by the SEC from quoting trades in increments less than a penny. This rule aims to maintain the integrity of the National Best Bid and Offer (NBBO), the benchmark for off-exchange market-makers.
How sub-penny trading works
Sub-penny trading occurs when a market participant in an undisplayed market center, such as a dark pool, outpaces a displayed limit order by a fraction of a cent, capturing the spread. Retail brokers accept sub-pennying orders to secure the best possible price for their clients, even if the trade is not on an exchange or ECN.
New rules and regulations
In 2022, SEC Chair Gary Gensler directed the SEC staff to explore the possibility of allowing stock exchanges to quote shares in increments less than $0.01. This potential change could enhance competition with wholesalers, who often beat publicly displayed prices by adding or subtracting hundredths of a penny.
Considering the volume of off-exchange sub-penny trading, Gensler is evaluating the possibility of shrinking the minimum tick size to better align with off-exchange activity.
Pros and cons of sub-penny trading
Examples of sub-penny trading strategies
Various sub-penny trading strategies are employed by market participants to capitalize on fractional price movements. One common example is the “stepping ahead” strategy, where traders use hidden bids to capture spreads by outpacing displayed limit orders. Another example involves leveraging technology to execute rapid-fire trades in undisplayed markets, aiming to gain a competitive edge.
Algorithmic sub-penny trading
Algorithmic trading has become a prevalent approach in sub-penny trading. Traders deploy complex algorithms that analyze market conditions and execute trades at lightning speed, taking advantage of fractional price differentials. This method allows for quick decision-making and the ability to navigate the dynamic landscape of undisplayed markets effectively.
