What it is
A stock split is a corporate action where a company divides its existing shares into multiple new shares. For example, in a 2-for-1 split, a shareholder owning 100 shares at $100 each would instead own 200 shares at $50 each. The total market capitalization of the company remains unchanged immediately after the split. This action aims to make shares more accessible to a broader range of investors by lowering the per-share price.
Stock splits often generate positive sentiment among investors, as a lower per-share price can increase trading liquidity and attract new buyers. Companies sometimes execute splits when their stock price becomes very high, making it seem less affordable. While a split itself doesn't change a company's fundamentals, it can precede periods of increased trading volume. Investors should understand that a split is merely an accounting adjustment.
Why it matters
Stock splits can make shares appear more affordable and increase liquidity, potentially impacting a stock's trading dynamics. It's a cosmetic change, not a fundamental one.
