What is Stock Split, Why Companies Do it and How it Works?

In simple terms, a stock split is a corporate decision to divide existing shares into multiple new shares. Imagine that you are holding a ₹100 note and you exchange that single note for two ₹50 notes.

Now your total cash value remains ₹100. However, you now hold two notes instead of one. A stock split operates on the exact same logic.

Key Takeaways

• A stock split increases the total number of outstanding shares of a company while reducing the price of each share in proportion to that.
• The total market capitalization of the company and the net monetary value of your investment will remain unchanged.
• Companies split their shares primarily to make them affordable for retail investors and to boost trading liquidity in the stock market.
• Unlike bonus shares, a stock split directly reduces the face value of the stock.
• There are no capital gains tax implications in India at the time a stock split takes place.

Introduction

Assume that you are watching a high-priced stock on the National Stock Exchange (NSE) or Bombay Stock Exchange (BSE). Due to its high price, you might back out from buying it. High share prices often act as a psychological barrier for small retail investors in India.

In situations where a single share costs thousands of rupees, buying even a small quantity requires a huge amount of capital. To solve this problem, very often publicly listed companies use a strategic financial tool known as a stock split. If you are just beginning your journey in the stock market, it’s quite natural that you might wonder: what is stock split?

In this comprehensive guide, we will break down what is stock split, why management teams approve it, how the mathematics behind it works, and how it impacts your Demat account as an Indian investor.

What is Stock Split and How does it Work?

To understand what stock split is at a fundamental level, we must look at how equity ownership is structured. When a company listed on the stock market decides to split its shares, it distributes additional shares to existing shareholders.

This is done based on a predetermined ratio.The most common stock split ratios in India are 1:2, 1:5, and 1:10.

The Two Scenarios

Let us consider a step-by-step example using an imaginary Indian company named Alpha Tech Limited.

• Pre-Split Scenario:

• • You own 10 shares of Alpha Tech Limited.
  • The current market price is ₹2,000 per share.
  • Your total portfolio value in Alpha Tech is ₹20,000 (10 shares × ₹2,000).
  • The face value of each share is ₹10.

Now, suppose Alpha Tech announces a 1:2 stock split. It is often called a 2-for-1 split.

• Post-Split Scenario:

• • Your share count doubles from 10 to 20 shares.
  • The price per share drops by half, from ₹2,000 to ₹1,000.
  • Your total portfolio value remains ₹20,000 (20 shares × ₹1,000).
  • The face value of each share is reduced from ₹10 to ₹5.

As you can see, your overall wealth did not increase or decrease instantly. So, what is the stock split achieving here?

It alters the structure of ownership by multiplying the quantity of shares while scaling down the price per share proportionally.

Top 4 Reasons Companies Split their Stocks

If a stock split does not increase the underlying market value of a company, why do corporate boards spend time and resources executing it? Indian companies choose to split their stocks for several clear strategic advantages:

1. Enhancing Retail Affordability

When a company performs exceptionally well over several years, its share price rises steadily. If the price reaches ₹5,000 or ₹10,000, buying a meaningful lot becomes difficult for salaried individuals and small traders.

By splitting the stock, the board brings the per-share price down to an accessible range, such as ₹500 or ₹1,000. This encourages smaller investors to participate.

2. Boosting Market Liquidity

Liquidity refers to how easily you can buy or sell a stock in the open market without causing dramatic price swings. High-priced shares often suffer from lower daily trading volumes. This is because fewer people trade them.

When a stock split lowers the share price, daily trading activity increases. Higher liquidity ensures smooth order execution for both retail and institutional investors.

3. Broadening the Shareholder Base

A diverse investor base is healthy for any listed enterprise. When share prices become affordable, thousands of new retail investors buy in. A broader shareholder base distributes risk and creates a stable foundation of long-term retail backing for the firm.

4. Positive Market Sentiment

In practice, companies rarely split shares when business performance is weak. A stock split usually follows a strong bull run in the stock’s history. As a result, the announcement of a split sends a strong positive signal to the market. It indicates that management is confident about future earnings and expects growth to continue.

Types of Stock Splits: Forward vs. Reverse

Stock splits generally fall into two distinct categories depending on corporate objectives:

1. Forward Stock Split

This is the standard form of stock split discussed throughout this article. In a forward split, the company increases the share count and decreases the price per share.

• Example ratios: 1:2, 1:5, or 1:10.
• Goal: Make shares cheaper and more liquid.

2. Reverse Stock Split

A reverse stock split works in the exact opposite direction. The company reduces the total number of outstanding shares to artificially increase the market price per share.

• Example ratio: 5:1 (every 5 shares are merged into 1 share).
• Goal: Elevate a falling stock price. Companies often do this if their stock drops into penny stock territory or faces the threat of exchange delisting due to minimum price requirements.

While forward splits are very common among growing Indian enterprises, reverse splits are relatively rare and usually point to underlying financial distress.

Stock Split vs. Bonus Shares: Key Differences

Indian retail investors frequently mix up stock splits and bonus issues because both result in additional shares landing in your Demat account. However, their accounting mechanisms are completely different.The table below highlights the primary differences:

Impact on Face Value and Market Capitalization

To evaluate corporate actions correctly, you must understand two key financial metrics:

1. Face Value

Face value is the nominal value assigned to a share by the company when issuing equity. In India, equity shares typically start with a face value of ₹10. When a 1:10 stock split occurs, the face value drops from ₹10 to ₹1.

The face value is important because corporate dividends in India are often declared as a percentage of the face value, not the market price.

2. Market Capitalization

Now let’s check how market capitalization is calculated. This is done by multiplying the total number of outstanding shares by the current market price per share.

Market Capitalization = Total Shares * Market Price Per Share

Because the share count increases by the exact same factor that the price decreases, the product of these two numbers remains identical. Therefore, a stock split has zero direct impact on a company’s market cap or its intrinsic business valuation.

Tax Implications and Portfolio Impact for Indian Investors

Understanding the tax laws surrounding corporate actions is essential for managing your personal finances in India.

Capital Gains Tax

Under the Indian Income Tax Act, a stock split is not classified as a transfer or sale of assets. With no money changing hands and no capital gain realized, no income tax or capital gains tax is triggered on the day of the split.

Cost of Acquisition

When a split occurs, your total cost of purchasing the original shares is spread evenly across the new, higher quantity of shares.

Calculation:

If you originally purchased 1 share for ₹10,000 and the stock undergoes a 1:5 split, you now hold 5 shares. Your adjusted cost of acquisition becomes:

₹10,000/5 = ₹2,000 per share

Period of Holding

For long-term or short-term capital gains tax calculations upon future sales, the holding period for the newly received split shares dates back to the original day you purchased the initial shares.

Real Examples of Stock Splits in India

Several prominent blue-chip companies in India have successfully used stock splits to increase accessibility:

• Tata Steel (2022):

In 2022, Tata Steel announced a 10-for-1 (1:10) stock split. The face value was reduced from ₹10 to ₹1 per share. This adjusted the stock price down from nearly ₹960 to around ₹96 per share, inviting massive retail participation across Indian brokerages.

• IRCTC (2021):

The Indian Railway Catering and Tourism Corporation executed a 1:5 stock split in October 2021. The face value changed from ₹10 to ₹2. As a result, the trading price went down from over ₹4,000 to around ₹800.

• Eicher Motors (2020):

Known for manufacturing Royal Enfield motorcycles, the company split its shares in a 1:10 ratio in 2020. The face value reduced from ₹10 to ₹1, reducing the per-share price from approximately ₹21,000 to ₹2,100.

Important Dates – Keep in Mind

When a company announces a stock split, keep track of three crucial dates:

1. Announcement Date: The day the company’s Board of Directors approves the proposal and informs stock exchanges.
2. Record Date: The cutoff date set by the firm to identify eligible shareholders listed in its records. You must own the shares before this date to receive split benefits.
3. Ex-Split Date: The day from which the stock begins trading at the new, lower adjusted price on the exchanges. In Indian markets, the ex-split date is typically set on or one trading day before the record date.

Conclusion

Understanding what stock split is helps you navigate stock market announcements without confusion. Purely a structural adjustment, a stock split divides existing shares into smaller units. It also lowers the per-share market price, and reduces face value with no altering of the underlying value of the company or your portfolio.

When it comes to retail investors in India, a stock split is generally a positive development. The best part is that it enhances liquidity, improves price accessibility, and makes it easier to accumulate shares of high-quality businesses over time.

Hence, whenever a company in your portfolio announces a split, be rest assured that your percentage ownership and long-term investment value remain fully intact.
