Stock Split
A stock split is a corporate action that divides existing shares into a larger number of shares at a proportionally lower price, increasing share count without changing the company's total market capitalisation.
In a stock split, the face value of the share is reduced in the same proportion as the split ratio. For example, in a 2-for-1 split, each ₹10 face value share becomes two ₹5 face value shares. The share price halves, but shareholders hold twice as many shares — their total investment value is unchanged on the day of the split (absent any market reaction).
Indian companies such as MRF, Honeywell Automation, and Page Industries have historically been among the highest-priced stocks on NSE/BSE, trading at ₹50,000–₹1,50,000 per share or higher. The reluctance of their managements to split the stock was sometimes cited as a factor limiting retail participation, since high nominal prices can psychologically deter small investors. Conversely, when Reliance Industries and several other large-caps conducted splits in past decades, traded volumes increased significantly post-split as the shares became more accessible to smaller investors.
A common misconception among new investors is that a stock split makes the company more valuable or is inherently a positive signal. It does not change the company's fundamentals, earnings, or intrinsic value. The per-share earnings and book value also reduce proportionately, keeping P/E and P/B ratios unchanged. The market sometimes reacts positively to split announcements — treating them as a sign of management confidence in future prospects — but this is a behavioural response, not a fundamental one.
For existing shareholders, the cost of acquisition adjusts automatically in demat accounts and for tax purposes. SEBI's circular on corporate actions ensures that depositories (NSDL and CDSL) update holdings post-split without any action required from the investor. The tax cost basis per share is adjusted so that the aggregate cost remains the same, preserving the investor's capital gains calculation.
A reverse stock split — where multiple shares are consolidated into fewer shares at a higher price — is rare among healthy Indian companies but has been used by stressed companies seeking to raise their share price above minimum listing thresholds or to appear more institutionally presentable.
