Understanding the concept of "bid size" is crucial in the world of finance. It refers to the total number of shares that an investor is willing to purchase for a particular security, typically measured in board lots. This information is important as it reflects the demand for a particular stock and can influence its market value. Essentially, the bid size is an indicator of the current market sentiment towards a security. As a knowledgeable investor, it is essential to keep an eye on the bid size when making investment decisions.
