Difference Between Bid and Ask Price of Stock
The bid rate refers to the highest rate at which the prospective buyer of the stock is ready to pay for purchasing the security required by him, whereas, the ask rate refers to the lowest rate of the stock at which the prospective seller of the stock is ready for selling the security he is holding.
The bid price is the highest amount of money a buyer is willing to pay for a particular product, commodity. It is termed in contrast to the selling price or the ask price, which is the amount that a seller is willing to sell a security for.
Investors are required by a market order to buy at the current Ask price and sell at the current bid price. In contrast, limit orders allow investors and traders to buy at the bid price and sell at the ask price.

Bid vs. Ask Price of Stock Infographics
Let’s see the top difference between Bid vs. Ask Price.
Key Differences
- In case of a stock, if one believes that the price is expected to go up, then the buyer would buy the stock at a price that he believes is appropriate or fair. This price at which the buyer wants to buy the stock is termed as bid. In the future, when the prices go up, the buyer now converts into a seller. He will now quote a price to sell in which he believes maximum profit can be made. This price is termed as Ask price
- There can be a case of multiple buyers bidding a higher amount. However, the same will not be applicable in case of ask price.
- For example, bidder A is ready to pay ₹5000 for a commodity while bidder B offers ₹5700 for the same commodity. Both these bidders may be encountered with a bidder C, which may offer a price higher than this. Eventually, the bidder with the highest amount wins. It is extremely beneficial for the seller as the pressure is now on the buyers go out to each other. Bidding is quite common in the case of art and unique or historic items. Such a scenario will not be possible in case of an ask price or a seller.
- Bid Price is known as the sellers’ rate because if one is selling the stock, then he will get the bid price. If you are buying the stock, then you will get the Ask Price. The difference between these two prices goes to the broker or the specialist that handles the transaction.
- The bid price is usually quoted low and is also designed in a way that the exact desired outcome is achieved. Since the seller will never sell at a lower rate, the ask price will always be higher. For example, if the ask price of a particular commodity is ₹2000 and a buyer is willing to pay ₹1500 for the same, he will quote an amount of ₹1000. It may look like a compromise, and both the parties will find a midway and agree to a price where they wanted to be from the beginning.
- The spread will only be positive when the Ask price is greater than the bid price. A higher spread indicates the wide difference between the two prices. It also makes it harder to generate a profit because the product or security will always be bought at a higher price and sold at a very low price.
- On the buy-side, prices are always in the decreasing order, and the topmost bid is considered as the best bid price, and on the sell, side prices are arranged in the increasing order, and the topmost ask price is considered as the best ask price. Average of best bid an average of the best ask price is considered as the ideal price of the stock.
