Spread

Definition

In trading, the spread refers to the difference between the bid price (the highest price a buyer is willing to pay) and the ask price (the lowest price a seller is willing to accept) for a security. It represents the immediate transaction cost for investors buying and selling.

Example

If a stock has a bid price of $20.00 and an ask price of $20.05, the bid-ask spread is 5 cents, which is the immediate cost to someone buying and then immediately selling the stock.
