Most investors never think this through clearly. This module covers exactly what equity ownership means | and what companies do to your shares over time. TK Tanmay Kurtkoti Founder & CEO, RupeeCase · QC Alpha ⏱ 14 min read ⟳ Updated 15 Jun 2026 ◆ Intermediate Equity is the most fundamental financial instrument | and also the most misunderstood in its mechanics. Most retail investors know they own "a piece of the company." Fewer understand what rights that ownership actually confers, or how those rights change when a company does a bonus issue, a rights issue, a buyback, or an ESOP grant. Understanding corporate actions isn't just academic. It directly affects your portfolio | sometimes your returns look better than they are because of splits, sometimes worse because of dilution. RupeeCase adjusts all historical prices for corporate actions, but you should understand exactly what's happening under the hood. ▼ Indian financial products landscape (2024) Source: SEBI, AMFI, NSE Mutual Funds AUM ₹67L Cr ETFs AUM ₹8L Cr REITs+InvITs ₹1.3L Cr SGBs Outstanding ₹3.5L Cr ## Ordinary shares vs preference shares Two main types of shares exist in Indian capital markets. When people say "shares" or "equity," they almost always mean **ordinary shares** (also called common shares or equity shares). Ordinary Shares Ownership with voting rights and residual claim on profits. You vote at AGMs, receive dividends if declared, and share in the upside (and downside) of the business. Most NSE-listed companies have only ordinary shares. Reliance Industries, Infosys, HDFC Bank | all ordinary shares. Preference Shares Priority claim on dividends (fixed rate) and on assets in liquidation | but typically no voting rights. Less common in Indian listed markets. More relevant for private equity and unlisted companies. If dividends aren't paid for 2+ years, preference shareholders typically gain voting rights under Indian company law. For systematic equity investing | which is what RupeeCase is built around | you will only ever be dealing with ordinary shares. The preference share structure matters more for understanding the liability side of a company's balance sheet. ## What equity ownership actually means When you own 100 shares of Reliance Industries out of its ~6.77 billion shares outstanding, you own approximately 0.0000015% of Reliance. That fraction entitles you to: * **Proportional claim on dividends** | if Reliance declares ₹9/share dividend, you receive ₹900 * **Voting rights at AGMs** | one vote per share on board appointments, major transactions, capital raises * **Residual claim in liquidation** | after all debt, preference shares, and liabilities are paid, ordinary shareholders split whatever remains * **Right of first refusal (pre-emption rights)** | if the company issues new shares, you have the right to buy new shares proportionally to maintain your ownership percentage (subject to conditions) The residual nature of equity ownership is why equity is both riskier and higher-returning than debt. Bondholders get paid first in liquidation. Shareholders get what's left | which in a growing company is substantial, and in a bankrupt company is zero. ## The five major corporate actions Companies regularly take actions that change the number of shares outstanding or their price. Every single one of these affects your portfolio calculations. Here's what each one does: ### 1. Bonus shares A bonus issue (also called a stock dividend or capitalisation issue) gives existing shareholders additional free shares in a fixed ratio. A 1:1 bonus means you receive one additional share for every share you hold | your shareholding doubles, but the share price halves to adjust. Your total value doesn't change on the day of the bonus. Why do companies do this? A growing company that has accumulated large reserves can use a bonus issue to convert those reserves into paid-up capital. It also makes the share price more "accessible" | a ₹2,000 stock might become a ₹1,000 stock after a 1:1 bonus, potentially improving liquidity and retail participation. | Before Bonus (1:1) | After Bonus (1:1) | | --- | --- | | 100 shares at ₹2,000 = ₹2,00,000 | 200 shares at ₹1,000 = ₹2,00,000 | | Company reserves: ₹500 Cr | Company paid-up capital: ₹500 Cr higher | | No change in underlying business value | No change in underlying business value | ### 2. Stock splits A stock split increases the number of shares by reducing the face value. A 10:1 split means each share becomes 10 shares | if Infosys had a face value of ₹10 and splits 10:1, the face value becomes ₹1 and the number of shares multiplies by 10. Share price adjusts proportionally. Economically identical to a bonus issue in outcome. Infosys did a 2:1 split in 1999, 2004, and 2018. Each split made the stock more accessible to retail investors and is part of the reason Infosys has remained one of India's most widely held stocks. ### 3. Rights issue A rights issue gives existing shareholders the right (but not obligation) to buy new shares at a discount to the current market price, in proportion to their existing holding. A 1:5 rights issue at ₹500 (when market price is ₹700) means: for every 5 shares you hold, you can buy 1 additional share at ₹500. * You can **subscribe** | pay ₹500 and receive the new share, maintaining your ownership percentage * You can **renounce** | sell your rights entitlement in the market (rights are tradeable on NSE for the subscription period) * You can **let them lapse** | your ownership percentage is diluted as new shares are issued to others **Rights issue math:** If you hold 500 shares in a 1:5 rights issue at ₹500 (market ₹700), you're entitled to 100 new shares. Subscribing costs ₹50,000 and gives you shares currently worth ₹70,000 | an immediate book profit. Not subscribing means your ownership is diluted without compensation. ### 4. Buybacks A buyback (share repurchase) is the company buying its own shares from the market, reducing the total shares outstanding. From a shareholder's perspective: each remaining share now represents a larger slice of the company. If Reliance has 6.77 billion shares and buys back 100 million, each remaining share's ownership fraction increases. India has two buyback routes: open market (company buys shares on exchange over time) and tender offer (company invites shareholders to sell at a premium price in a set window). Buybacks are often more tax-efficient than dividends for shareholders | LTCG tax vs dividend tax treatment. ### 5. ESOP (Employee Stock Option Plans) ESOPs grant employees the right to buy company shares at a predetermined exercise price, usually below market price. When employees exercise options, new shares are issued | **diluting existing shareholders**. This is the corporate action that most retail investors underappreciate. A company with ₹100 Cr profit and 1 crore shares has EPS of ₹100. If it grants ESOPs equivalent to 10 lakh shares and employees exercise them, shares outstanding become 1.1 crore | EPS drops to ~₹90.9 on the same profit. That's dilution. Always check the diluted EPS, not just basic EPS, when valuing companies with large ESOP programmes (especially IT and startup-adjacent companies). ## How corporate actions affect backtests and factor signals A stock that was at ₹2,000 before a 1:1 bonus appears to have dropped 50% the next day. That's not a loss | it's a mechanical price adjustment. Any backtest or factor model that doesn't adjust for corporate actions will produce garbage results. RupeeCase and corporate action adjustments All price data on RupeeCase is **adjusted for all corporate actions** | bonus issues, splits, dividends, rights issues | using the NSEINDIA official adjustment factors. When you see a momentum signal or a 12-month return calculation, it reflects the true economic return, not an artificial number distorted by a bonus issue. This is one of the more important data hygiene decisions in building a reliable factor engine.

Price adjusts proportionally. No change in total value on issue date. Stock splitReduction in face value with proportional increase in shares. Economically equivalent to a bonus issue. Rights issueOffer to existing shareholders to buy new shares at a discount, in proportion to existing holding. Can be subscribed, renounced, or allowed to lapse. BuybackCompany purchases its own shares from the market, reducing shares outstanding and increasing the ownership fraction of remaining shareholders. ESOP dilutionReduction in EPS caused by new shares issued when employees exercise stock options. Check diluted EPS, not basic EPS, for companies with large ESOP programmes. Adjusted priceHistorical price recalculated to account for all corporate actions, so that returns reflect true economic performance rather than mechanical price changes. TK A note from the author Why this matters Understanding equity share structure, voting rights, and corporate actions is not optional | it is foundational. I have seen investors get blindsided by bonus issues, stock splits, and rights offerings simply because they never learned the mechanics. In Indian markets, where promoter holdings and corporate governance quirks create real pricing effects, this knowledge gives you a tangible edge.
