Bid-Ask Spread

The bid-ask spread is the gap between the highest price a buyer will pay and the lowest price a seller will accept, representing a key cost of trading.

Every quote has two sides: the bid, what buyers offer, and the ask, what sellers demand. The spread between them is effectively a transaction cost that traders pay to get in and out of a position.

Highly liquid assets like large-cap stocks have tiny spreads, while thinly traded securities can have wide ones. A wide spread means you buy a bit higher and sell a bit lower than the mid price.

Active traders watch spreads closely because they eat into returns, especially for frequent trading. Tight spreads are a hallmark of a healthy, liquid market.

Example

If a stock is bid at $9.98 and offered at $10.02, the bid-ask spread is 4 cents.
