Investopedia / Julie Bang

What Is a Market Maker?

The term “market maker” refers to a firm or individual who actively quotes both sides of a market in a particular security by providing bids and offers (known as asks) along with the market size of each. In fact, they are obligated to engage in such trading activity.

Market makers provide liquidity and depth to markets and profit from the difference in the bid-ask spread. They may also trade for their own accounts. Such trades are known as principal trades.

Key Takeaways

• A market maker is an individual participant or member firm of an exchange that buys and sells securities for its own account.
• Market makers provide the market with liquidity and ensure its ongoing functionality.
• Brokerage houses are the most common types of market makers, providing purchase and sale solutions for investors.
• Market makers are compensated for the risk of holding assets because a security’s value may decline between its purchase and sale to another buyer.
• They also make money on the bid-ask spread.

Understanding Market Makers

Many market makers are brokerage houses that provide trading services for investors. They make markets in an effort to keep financial markets liquid.

A market maker can also be an individual trader, who is commonly known as a local. The vast majority of such market makers work on behalf of large institutions due to the lot sizes needed to facilitate the volume of purchases and sales.

Each market maker displays buy and sell quotations (two-sided markets) for a guaranteed number of shares. Once the market maker receives an order from a buyer, they immediately sell their position of shares from their own inventory. This allows them to complete the order.

A market maker must commit to continuously quoting prices at which it will buy (or bid for) and sell (or ask for) securities. Market makers must also quote the volume in which they’re willing to trade along with the frequency of time they will quote at the best bid and best offer prices.

Market makers must stick to these parameters at all times, no matter what their market outlook. When markets become erratic or volatile, market makers must remain disciplined in order to continue facilitating smooth transactions.

Market makers must operate under a given exchange’s bylaws, which are approved by a country’s securities regulator. In the United States, that regulator is the Securities and Exchange Commission (SEC). The rights and responsibilities of market makers vary by exchange and by the type of financial instrument they trade, such as equities or options.

Fast Fact

Making a market  signals a willingness to buy and sell the securities of a certain set of companies to broker-dealer firms that are members of an exchange.

How Market Makers Earn Revenue

Market makers are compensated for the risk of holding securities (that they make markets for) that may decline in value after they’re purchased from sellers and before they’re sold to buyers.

In addition, they earn money from the aforementioned spread on each security they cover. For example, when an investor searches for a stock using an online brokerage firm, it might observe a bid price of $100andanaskpriceof$100.05. This means the broker purchases the stock for $100,thensellsittobuyersfor$100.05. Through high-volume trading, a small spread can add up to a large amount of daily revenue.

Market Makers vs. Designated Market Makers

Many exchanges use a system of market makers who compete to set the best bid or offer so they can win the business of incoming orders. But some entities, such as the New York Stock Exchange (NYSE), have what’s called a designated market maker (DMM) system instead.

Previously referred to as specialists, DMMs are essentially lone market makers with a monopoly on the order flow of a particular security or securities. Because the NYSE is an  auction market, bids and asks are competitively forwarded by investors.

Here’s how it works: The DMM posts these bids and asks for the entire market to see and ensures they are reported in an accurate and timely manner. They also make sure that the best price is always maintained, that all marketable trades are executed, and that order is maintained on the floor.

The DMM must also set the opening price for the stock each morning, which can differ from the previous day’s closing price based on after-hours news and events. They determine the correct market price based on supply and demand.

Market Makers by Exchange

As noted above, market makers provide trading services for investors who participate in the securities market. Their activities through their entity trading accounts produce and boost liquidity within the markets.

Exchanges throughout the world make use of market makers. Here are some of the most popular ones:

The NYSE and Nasdaq are the two main stock exchanges in the U.S. Both are based in New York.

According to the NYSE, a market maker is an “ETP holder or firm that has registered” to trade securities with the exchange.

Over at the Nasdaq, a market maker is a “member firm that buys and sells securities at prices it displays in NASDAQ for its own account (principal trades) and for customer accounts (agency trades).”

Some of the designated market makers in New York include:

• Citadel Securities LLC
• GTS Securities LLC
• Virtu Americas LLC

The Frankfurt Stock Exchange (FRA) is one of seven stock exchanges in Germany. It is also the largest. The exchange, which is operated by Deutsche Börse AG, calls its market makers designated sponsors.

Important

Market makers facilitate a smooth flow of market activity by making it easier for investors and traders to buy and sell. Without market makers, there could be insufficient transactions and fewer opportunities to invest efficiently.

Example of a Market Maker

Let’s say there’s a market maker in XYZ stock. They may provide a quote of $10.00-$10.05 or 100 x 500. This means that they bid (they will buy) 100 shares at $\mathrm{10.00.}The{y}^{\prime }llalsooffer(theywillsell)500sharesat$10.05. Other market participants may then buy (lift the offer) from the market maker at $10.05orselltothem([hitthebid](https://www.investopedia.com/terms/h/hitthebid.asp))at$10.00.

What’s the Role of a Market Maker?

A market maker plays a key role in the securities market by providing trading services for investors and boosting market liquidity. Specifically, they provide bids and offers for securities, along with the market size.

Why Do Market Makers Matter?

They matter because they ensure that the securities markets continue to function. Market makers must commit to providing markets for securities on both the buy and the sell sides.

How Do Market Makers Work?

Market makers operate and compete with each other to attract the business of investors by setting the most competitive bid and ask offers. In some cases, exchanges may have designated market makers (or specialists), each of whom is responsible for making a market in specific securities. The specialist process exists to ensure that all marketable trades are executed at a fair price in a timely manner.

The Bottom Line

Market makers provide assurance to the investment community that trading activities can operate smoothly. Whether an entity or individual, market makers are obligated to provide bids and offers for securities—that is, to make markets—so that markets retain some degree of liquidity and investors can continue to buy and sell.
