What Is the Difference Between the Bid and Ask Price of a Stock and the Last Price?
What Do the Bid and Ask Sizes in Stocks Mean?
What Factors Influence Bid and Ask Prices?
In the world of trading, understanding the bid price and ask price is essential for making smart investment decisions. These two prices appear in every stock quote and are the foundation of how assets are bought and sold. The highest price a buyer is willing to pay is the bid, while the lowest price a seller will accept is the ask. The difference between them — called the spread — offers insights into market supply and demand, trading costs, and liquidity. Knowing how these values work helps investors navigate asset pricing more effectively.
The bid represents the highest price that a buyer is willing to pay for a financial security, while the ask is the lowest price that a seller is willing to accept. Together, they form the bid-ask spread, which reflects the difference between what buyers want to pay and what sellers want to receive. For instance, if a stock has a bid of $20.00 and an ask of $20.10, the bid-ask spread is $0.10.
This spread is crucial when choosing how to place a trade. With a market order, traders accept the current ask price (if buying) or bid price (if selling), which ensures execution but not the best price. A limit order, on the other hand, allows traders to set a desired purchase or sell price, waiting for the market to match it. Both types of orders interact differently with bid and ask prices, shaping execution timing and success.
Stock prices are determined by matching orders submitted by brokers on a stock exchange. Buyers submit bids, and sellers place asks. The best available bid price represents the highest demand, while the lowest ask reflects current supply. This matching process determines the current price at which trades happen. When natural matching is not possible, market makers step in, continuously quoting buy and sell prices to maintain order flow and provide liquidity.
A narrow bid-ask spread usually means a highly liquid stock, while a wide spread often points to low liquidity or less trading volume.
The bid-ask spread can vary significantly depending on the liquidity and popularity of a security. For highly liquid stocks like Amazon, the spread may be just $0.01. However, in penny stocks or over-the-counter markets, spreads can be several cents wide, sometimes as much as $0.05 on a $0.50 stock—a 10% difference.
For retail traders, wide spreads can be costly. Paying the ask and selling at the bid results in an immediate loss, unless the price moves favorably. This difference becomes a form of market maker's profit, earned through high trading volumes.
Understanding this cost helps investors avoid overpaying for illiquid assets and assess the risk involved. While market makers ensure smooth trading, their role also highlights why the spread exists and how it impacts your bottom line.
Imagine you’re buying shares of Bluth’s Bananas. The best bid is $15.20, and the best ask is $15.25. First off, open account and place a market order to buy 100 shares. Your broker executes it at the ask price of $15.25. The seller receives $15.20 (the quoted bid price), and the market maker keeps the $0.05 spread as profit.
After this transaction, the bid and ask prices update based on remaining orders. This example shows how even a small spread generates profits when multiplied by large trading volume.
Market makers are firms or individuals that help provide liquidity in financial markets. They place simultaneous buy and sell orders at different prices to ensure there is always a bid and ask for a security. They profit from the spread, buying at the bid and selling at the ask, and help facilitate transactions when market participants do not naturally match.
By maintaining an inventory of shares, they fulfill orders instantly and help stabilize trading activity, making them essential to a functioning market.
A trade only happens when a buyer agrees to pay the ask price, or a seller agrees to the bid price. This crossing of the spread is what enables execution. Wider spreads reduce the chance of matching orders, thus reducing liquidity. This is why trades are more frequent in markets with narrow bid-ask spreads.
The last price is the execution price of the most recent trade. It differs from the bid and ask prices, which are current quotes. After a trade, the last price updates, while bid and ask shift with new orders.
Bid-ask size indicate the number of shares available at those prices. Often quoted in lots of 100, larger sizes mean more liquidity. Traders use this to assess market depth and interest at different price points.
Supply and demand are the primary forces. If demand outstrips supply, bid price and ask price rise. Factors include:
Understanding bid and ask prices, and the bid-ask spread, is crucial for navigating the stock market. It reflects liquidity, transaction costs, and market health. With the help of market makers, traders get continuous access to buying and selling options. By grasping these basic concepts, you can place better trades and avoid common pitfalls.

You buy at the ask price and sell at the bid price.
You sell at the bid price, which is the highest price a buyer is offering.
That would indicate a system or reporting error; normally, ask price is always higher than bid.
In the bid-ask spread, the best bid is the highest current bid price; the best ask is the lowest current ask price.
