Market mechanics

    What is the role of a market maker in stock execution?

    By Easy Money Scanner · Educational reference · Not investment advice

    The short answer

    A market maker is a registered firm that continuously quotes both buy and sell prices for a security, providing liquidity and facilitating smoother, faster order execution for retail and institutional traders.

    How it works

    Market makers profit from the bid-ask spread and are obligated under exchange rules to maintain fair and orderly markets, stepping in when there's a temporary imbalance between buyers and sellers.

    An example

    When you place a market order for a thinly traded stock, a market maker may fill it from its own inventory rather than waiting for a matching retail order.

    Risk & limitations

    Market makers' quoted prices can widen sharply during volatile periods, increasing your effective trading costs even though a market exists.

    Examples are hypothetical, not trade recommendations. US contract and regulatory references do not automatically apply in Canada. Rules, margin requirements and broker policies can change; confirm them with the relevant authority and your broker.
