The Bid/Ask Spread is the amount by which the ask price exceeds the bid price expressed as a net value. The Bid/Ask Spread % is the amount by which the ask price exceeds the bid price expressed as a percentage. The Spread is the measurement of market liquidity.

The bid-ask spread is the difference between the highest price a buyer will offer (the bid price) and the lowest price a seller will accept (the ask price). Typically, an asset with a narrow bid-ask spread will have high demand.

The term "bid" refers to the highest price a buyer will pay to buy a specified number of shares of a stock at any given time. The term "ask" refers to the lowest price at which a seller will sell the stock.

The average spread for S&P 500 stocks is around 13% to 18%. Why the bid-ask spread is a transaction cost? Investors purchase the stocks at the ask price. Then, they further sell it at a bid price.

Through Spreads

Market makers buy and sell stocks on behalf of their clients, and they make money from the difference between the bid and ask price (the spread). The bid price is the highest price that a buyer is willing to pay for a stock, and the ask price is the lowest price that a seller is willing to accept.

The bid-ask spread is a measure of liquidity of firms' securities that was proposed by Demsetz (1968). A practical measure of stock market liquidity combines all of its dimensions (volume, time and price). As bid-ask spread increases the market is likely to be less liquid.

The bid-ask spread works to the advantage of the market maker. Continuing with the above example, a market maker quoting a price of $10.50 / $10.55 for ABC stock indicates a willingness to buy ABC at $10.50 (the bid price) and sell it at $10.55 (the asked price). The spread represents the market maker's profit.

By selling at the higher ask price and buying at the lower bid price over and over, market makers can take the spread as arbitrage profit. Even a small spread can provide significant profits if traded in a large quantity all day. Assets in high demand have smaller spreads as market makers compete and narrow the spread.

In the stock market, a buyer will pay the ask price and a seller will receive the bid price because that's where supply meets demand. The bid-ask spread is a type of transaction cost that goes into the pocket of the market maker, an intermediary who keeps the market orderly.

What is the formula for the bid-ask spread? ›

The bid-ask spread equals the lowest asking price set by a seller minus the highest bid price offered by an interested buyer. Electronic exchanges such as the NYSE or Nasdaq are responsible for matching bid and sale orders in real-time, i.e. facilitating transactions between the two parties, buyers and sellers.

Market makers profit by buying on the bid and selling on the ask. So if a market maker buys at a bid of, say, $10 and sells at the asking price of $10.01, the market maker pockets a one-cent profit. Market makers don't make money on every trade.

Markets with a wide bid-ask spread are typically less liquid than markets with a narrow spread. The spread widens because there aren't high levels of supply and demand, or buy and sell orders to easily match up.

The ask price is the lowest price that a seller will accept. The difference between the bid and ask prices is called the spread. The higher the spread, the lower the liquidity. A trade will only occur when someone is willing to sell the security at the bid price, or buy it at the ask price.

What Is The Difference Between Bid Size and Ask Size?
