What is a common misconception about stock splits?

A common misconception about stock splits is the belief that they increase the actual value of the investment. In reality, stock splits do not change the overall value of a shareholder's investment. When a company undergoes a stock split, it increases the number of shares outstanding while proportionately reducing the price per share. For example, in a 2-for-1 split, a shareholder with one share valued at $100 prior to the split will then hold two shares at $50 each. The total investment value remains the same at $100; it is simply distributed over a greater number of shares. Therefore, while the number of shares owned increases, the total market capitalization of the company and the value of the investment does not.

Understanding this misconception is important as it helps investors maintain a clear perspective on the implications of stock splits, rather than misinterpreting them as a boost in value or performance.
