Stock Split
A stock split divides each existing share into multiple shares by lowering the face value, increasing the share count and reducing the per-share price without changing total value.
A stock split answers a question that confuses many first-time investors: if a company splits its shares, did I just become richer? The honest answer is no, and understanding why is the whole point.
The mechanics
Indian shares carry a face value, often ₹10, ₹5, ₹2 or ₹1. In a split, the company reduces this face value, say from ₹10 to ₹1, and gives you ten shares for every one you held. If you owned 100 shares at ₹2,000 each, after a 10-for-1 split you own 1,000 shares at roughly ₹200 each. Your total holding is still ₹2,00,000. Nothing of economic substance has changed; the pizza is simply cut into more slices.
Why companies do it
The usual reason is affordability and liquidity. When a stock trades at several thousand rupees, small retail investors and SIP-style buyers find it harder to buy round lots. Splitting brings the price into a more accessible range, often widening the shareholder base and improving day-to-day trading volume on NSE and BSE. A split is also a confidence signal, since managements rarely split a stock they expect to languish. Note the difference from a bonus issue, where free shares are given out of reserves; a split instead carves up the existing face value.
What it means for you
A split does not create wealth, change your ownership percentage, or alter the company's market capitalisation. For tax purposes in India, your original cost is simply spread across the larger number of shares, and the holding period carries over, so it does not reset your long-term capital-gains clock. The real lesson: never buy a stock just because it announced a split. Judge the business on earnings, cash flow and valuation. A split is cosmetic; a cheaper per-share price is not the same thing as a cheaper company.
