Market maker

A market maker or liquidity provider is a company or an individual that quotes both a buy and a sell price in a tradable asset held in inventory, hoping to make a profit on the difference, which is called the bid–ask spread or turn.^[1] This stabilizes the market, reducing price variation (volatility) by setting a trading price range for the asset.

In U.S. markets, the U.S. Securities and Exchange Commission defines a "market maker" as a firm that stands ready to buy and sell stock on a regular and continuous basis at a publicly quoted price.^[2] A Designated Primary Market Maker (DPM) is a specialized market maker approved by an exchange to guarantee a buy or sell position in a particular assigned security, option, or option index.^[3]
