Understanding Market Makers: The Good, the Bad, and the Future
Written on
Chapter 1: The Role of Market Makers
On a bright Monday morning, Lisa, a novice investor, eagerly logged into her brokerage app. She felt a blend of excitement and anxiety as she placed her first order to purchase shares of a promising technology company. Unbeknownst to her, her order was about to traverse a complex network of market makers and high-frequency traders before it reached the exchange.
Every day, countless retail investors like Lisa engage with the stock market, often oblivious to the sophisticated mechanisms that facilitate their trades. Central to this system is the market maker, a pivotal figure whose function has undergone significant changes over the last two centuries.
Chapter 1.1: The Evolution of Market Making
Market making has its roots in the 19th century, coinciding with the establishment of stock exchanges such as the New York Stock Exchange (NYSE). On bustling trading floors, individuals known as "specialists" served as market makers, providing essential liquidity and maintaining order in the marketplace.
Key Milestones in Market Making History:
- The introduction of electronic trading in the 1980s transformed market making, enabling quicker execution and lower trading costs.
- By the 1990s, high-frequency trading firms, equipped with advanced algorithms, became prominent market makers, executing thousands of trades in mere milliseconds.
Chapter 1.2: How Market Makers Function
Market makers are crucial for providing liquidity and ensuring price stability within financial markets. They achieve this by consistently quoting bid and ask prices for securities, making sure there are accessible prices for traders to buy or sell.
The difference between the bid and ask prices is referred to as the bid-ask spread. Market makers generate profit from this spread by purchasing securities at the bid price and selling them at the ask price. They also manage their risk by adjusting quotes based on market conditions, volatility, and inventory levels.
For instance, if Tesla shares are priced at $300, a market maker may quote a bid price of $299.95 and an ask price of $300.05, resulting in a 10-cent spread. If an investor sells a share to the market maker at the bid price, the market maker captures the 10-cent spread.

Chapter 2: The Dark Side of Market Making
Despite the vital functions of market makers, their operations can also present challenges. A significant concern is the potential for conflicts of interest, especially when market makers are linked to brokerages or trading firms.
The Robinhood and Citadel incident in 2021 brought these issues to light. Robinhood, a widely used brokerage app, faced allegations of directing its customers' orders to Citadel Securities, a market maker, in exchange for payment. This practice, known as payment for order flow (PFOF), raised questions about whether retail investors were receiving optimal prices for their trades.
Another troubling aspect involves the potential for market manipulation by high-frequency traders. These firms can exploit their speed advantage to engage in predatory trading tactics, such as front-running or spoofing, which may distort market prices and disadvantage ordinary investors.
Chapter 3: Regulatory Landscape and Future Prospects
To tackle these issues, regulatory entities like the Securities and Exchange Commission (SEC) have established rules to enhance transparency and protect retail investors. For instance, the SEC's Regulation NMS (National Market System) mandates that brokers execute trades at the best available price, irrespective of the trading venue.
Nevertheless, some argue for further action to create a more equitable environment for retail investors. Proposed measures include banning PFOF, increasing transparency regarding market maker activities, and fostering competition within the market-making sector.
As technology progresses, the future of market making will likely be influenced by advancements in artificial intelligence and machine learning. While these innovations may enhance efficiency and liquidity, they also introduce new challenges concerning fairness and transparency.

Chapter 4: Conclusion: Empowering Investors
For Lisa and many retail investors, navigating the stock market can be intimidating. While market makers play an essential role in ensuring liquidity and price stability, their actions can also lead to unforeseen consequences.
By gaining a deeper understanding of market making's history and intricacies, investors can make better-informed choices and advocate for a fairer, more transparent financial system. As the saying goes, "knowledge is power" — and in the investment realm, that power can truly make a significant difference.
