What Is it to Make a Market?

To make a market means that a dealer or market maker is prepared to both buy and sell a particular security by providing a two-sided quote with both a bid and an ask price. This service ensures liquidity and enables efficient trading in securities markets. We will explore how market makers operate, the important role they play in financial markets, and the risks involved in making a market.

Understanding Market Making

To make a market is to display a bid (where you are willing to buy) and an ask or offer (where you are willing to sell). If you were a grocer, for instance, and were asked to make a market on the price of an apple, you might indicate $0.10 - $0.50 ("ten cents bid at fifty cents"). This means you'd be willing to buy an apple for a dime, and sell an apple for half a dollar. The key point is that when asked to make a market, you do not necessarily know in advance if the requester is an interested buyer or seller.

Market makers and dealers are the ones that make markets on securities exchanges. Market makers are market participants or member firms of an exchange that buy and sell securities against other counterparties at prices displayed in an exchange’s trading system for their own accounts (called principal trades) and for customer accounts (called agency trades). Market makers can enter and adjust quotes to buy or sell, enter, and execute orders, and clear those orders.

Market makers exist under rules created by stock exchanges approved by a securities regulator. In the U.S., the Securities and Exchange Commission (SEC) is the main regulator of the exchanges. Market maker rights and responsibilities vary by exchange and the market within an exchange, such as equities or options.

Fast Fact

Market makers make money via the spread on each security they cover—namely, the difference between the bid and ask price; they also typically charge investors fees to use their services.

How Market Makers Operate

In order to make a market, a brokerage firm must be willing to hold a disproportionately large amount of a given security so it can satisfy a high volume of market orders in a matter of seconds at competitive prices. In contrast to a conventional brokerage, being a market maker requires a higher risk tolerance because of the high amounts of a given security that a market maker must hold.

Market makers promote market efficiency by keeping markets liquid. To ensure impartiality for their clients, brokerage houses that function as market makers are legally required to separate their market-making activities from their brokerage sales operations.

Important

Market makers smooth out the process of trading by making it easier for investors and traders to buy and sell securities; if there were no market makers, it could mean not enough transactions and not enough trading going on to keep the process fluid.

The Role of Market Makers in Liquidity

If investors are selling, market makers are obligated to keep buying, and vice versa. They are supposed to take the opposite side of whatever trades are being conducted at any given point in time. As such, market makers satisfy the market demand for securities and facilitate their circulation. The Nasdaq, for example, relies on market makers within its network to ensure efficient trading.

Market makers profit through the market-maker spread, not from whether a security goes up or down. They are supposed to buy or sell securities according to what kind of trades are being placed, not according to whether they think prices will go up or down.
