The lowest price at which a security is offered for sale is known as the ask price. This is essentially the minimum amount that a seller is willing to accept in exchange for their security. It is an important concept in finance, as it helps determine the current market value of a security. The ask price is influenced by various factors, such as supply and demand, market conditions, and the perceived value of the security. Understanding the ask price is crucial for any investor looking to make informed decisions in the stock market.
