Market Maker

Definition

A market maker is a financial intermediary that provides liquidity to the markets by being willing to buy and sell securities at any time. They play a crucial role in ensuring there is enough activity in the market, which helps maintain price stability and enables smoother transactions for investors. By quoting both buy and sell prices, market makers facilitate trading and help reduce the spread between the bid and ask prices, making it easier for traders to enter or exit positions in options and other financial instruments.
