Companies like Apple (AAPL), Tesla (TSLA), and Google (GOOGL) have used stock splits to manage their stock prices and broaden their shareholder base.

Understanding Stock Splits

A stock split occurs when a company divides its existing shares into multiple shares. For example, in a 2-for-1 stock split, each shareholder receives two shares for every one share they owned, effectively halving the price of each share. The primary reason for a stock split is to make the stock more affordable and liquid, attracting more investors. While the number of shares increases, the overall market capitalization of the company remains the same.
