The act of a publicly-traded company increasing the number of outstanding shares while maintaining the same market capitalization. In other words, a company engages in a stock split in order to decrease its share price by increasing the number of shares available. Current holders of the stock are given more shares so that they maintain the same percentage of ownership in the company. For example, a company with a share price of $400 may double the number of shares so that the share price drops to $200. Companies conduct stock splits for a number of reasons; one possible reason is to keep its shares affordable for investors. See also: Last Split, Split Ratio, Split Adjusted.
