A stock split is a corporate action where a company divides its existing shares into multiple new shares, reducing the price per share proportionally without changing the company's total market capitalisation. For example, in a 5:1 split, a shareholder holding 100 shares at ₹1,000 each would end up with 500 shares at ₹200 each. Companies typically split their stock to make shares more affordable and accessible to a wider pool of retail investors. Recent high-profile stock splits in India—including those by companies like MRF and Page Industries—have sparked renewed retail investor interest in such stocks.
