Market-Making System

The creation of market activity when a brokerage or bank maintains a firm bid-and-ask price in a given security by standing “ready, willing, and able” to buy or sell at publicly quoted prices. Proponents of the official market-making system claim market makers add to market liquidity and depth by taking a short or long position for a time, thus assuming some risk, in the hope of making a small profit.
