Sometimes companies split their outstanding shares into more shares. If a company with 1 million shares executes a two-for-one split, the company would have 2 million shares. An investor with 100 shares before the split would hold 200 shares after the split. The investor's percentage of equity in the company remains the same, and the share price of the stock owned is one-half the price of the stock on the day prior to the split.
