Stock Split

A stock split is a corporate action where a company increases its number of outstanding shares by dividing each existing share into multiple new shares. In a 2:1 split, every shareholder gets two shares for each one they held, but the price per share halves. A 5:1 split gives five shares for each one held, with the price dropping to one-fifth. The total value of your holding remains unchanged immediately after the split.

Companies typically split their stock when the per-share price has risen to levels that may deter retail investors. If a company's shares trade at INR 5,000, a 5:1 split brings the price to INR 1,000, making it more accessible for smaller investors and improving lot size affordability for futures trading. In India, the face value of the share changes accordingly — a INR 10 face value becomes INR 5 in a 2:1 split or INR 2 in a 5:1 split.

High-profile Indian stock splits include MRF (which has avoided splits, keeping its share price above INR 1 lakh), Reliance Industries (multiple splits over decades), and TCS (which split 2:1). When a split is announced, the stock often rallies in anticipation because the market interprets splits as a signal of management confidence — companies rarely split shares when they expect business to deteriorate.

The record date for a stock split is set by the board of directors, and shares are automatically adjusted in your Demat Account by the depository (NSDL or CDSL). No action is required from shareholders. Historical price charts on NSE/BSE are retroactively adjusted for splits to maintain visual consistency and accurate technical analysis.

A reverse stock split (consolidation) is the opposite — multiple shares are combined into one, increasing the per-share price. This is rarer in India and typically done by companies whose stock has fallen to very low prices, often to avoid Penny Stock classification or exchange surveillance measures. SEBI requires board and shareholder approval for both splits and reverse splits.
