What is Bid and Ask ?

The bid price refers to the highest price a buyer will pay for a security. The ask price refers to the lowest price a seller will accept for a security.

The difference between bid and ask prices is called spread. It is a key indicator of the liquidity of the asset. In general, the smaller the spread, the better the liquidity.

Key Takeaways

✓ The bid price refers to the highest price a buyer will pay for a security.
✓ The ask price refers to the lowest price a seller will accept for a security.
✓ The difference between these two prices is known as the spread; the smaller the spread, the greater the liquidity of the given security.

Understanding Bid and Ask

The term “bid and ask” (also known as “bid and offer”) refers to a two-way price quotation that indicates the best potential price at which a security can be sold and bought at a given point in time. The bid price represents the maximum price that a buyer is willing to pay for a share of stock or other security. The ask price represents the minimum price that a seller is willing to take for that same security.

The average investor contends with the bid and ask spread as an implied cost of trading. For example, if the current price quotation for the stock of ABC Corp. is $10.50 / $10.55, investor X, who is looking to buy A at the current market price, would pay $10.55, while investor Y, who wishes to sell ABC shares at the current market price, would receive $10.50.

Volatility of Bid-Ask Spread

The bid-ask spread can widen dramatically during periods of illiquidity or market turmoil, since traders will not be willing to pay a price beyond a certain threshold, and sellers may not be willing to accept prices below a certain level.

Spread is the difference between a Bid Price and an Ask Price

Bid prices refer to the highest price that traders are willing to pay for a security. The ask price, on the other hand, refers to the lowest price that the owners of that security are willing to sell it for. If, for example, a stock is trading with an ask price of $20, then a person wishing to buy that stock would need to offer at least $20 in order to purchase it at today’s price. The gap between the bid and ask prices is often referred to as the bid-ask spread.

What Does It Mean When the Bid and Ask Are Close Together ?

When the bid and ask prices are very close, this typically means that there is ample liquidity in the security. In this scenario, the security is said to have a “narrow” bid-ask spread. This situation can be helpful for investors because it makes it easier to enter or exit their positions, particularly in the case of large positions.

How Are the Bid and Ask Prices Determined ?

Bid and ask prices are set by the market. In particular, they are set by the actual buying and selling decisions of the people and institutions who invest in that security. If demand outstrips supply, then the bid and ask prices will gradually shift upwards.

Conversely, if supply outstrips demand, bid and ask prices will drift downwards. The spread between the bid and ask prices is determined by the overall level of trading activity in the security, with higher activity leading to narrow bid-ask spreads and vice versa.
