Trading Volume (4/5)

Despite what you may have learned in science class, volume in this case is not equal to length times width times height. Here, volume represents how many shares of a stock have been purchased or sold over the course of a certain time frame, such as a day. It is important to note that volume will continue to change even when the same share is exchanged multiple times. Investors Underground even calls this the “lifeblood of any stock,” because it offers insight into how people are reacting to changes in a company or its stock.
