Businesses often reward their shareholders through various means, including dividends or additional shares. Bonus shares and stock splits are the two common methods used for this purpose. Both mechanisms aim to enhance shareholder value but operate in different ways.

In this article, we will look at the differences between a stock split and bonus shares, understand the concept of bonus share vs. stock split, and explore how each strategy impacts shareholders and the overall dynamics of a business.

What is a bonus issue?

Usually, when a business issues additional shares to its existing shareholders in a predetermined proportion, it is known as a bonus issue. For instance, in a 3:1 bonus issue, shareholders receive three additional shares for each share they currently hold.

Pros and Cons of a Bonus Issue

A bonus issue refers to the issuance of additional shares by a company to its existing shareholders without any extra cost, based on their current shareholding. It is often seen as a signal of confidence by the company’s management and is used to reward shareholders. However, while a bonus issue has several advantages, it also comes with certain limitations.

One key advantage of a bonus issue is improved liquidity. When the number of outstanding shares increases, trading volumes may rise, making the stock more accessible to a wider range of investors. A bonus issue also makes shares more affordable on a per-share basis, which can attract retail participation. Additionally, it reflects the company’s strong reserves and retained earnings, signalling financial stability and long-term confidence in business prospects. For existing shareholders, it increases the number of shares held without requiring additional investment.

On the downside, a bonus issue does not create real wealth for shareholders, as the overall value of their investment remains unchanged. The share price adjusts downward proportionately after the bonus issue. It can also lead to higher expectations among investors, which may create pressure on the company to sustain performance. From a financial perspective, frequent bonus issues may reduce free reserves, limiting funds available for future expansion or contingencies.

For example, if an investor owns 100 shares of a certain large-cap stock, with a 3:1 bonus issue, they would receive 300 additional shares (3 * 100), resulting in 400 shares (100 initial shares + 300 additional shares).

What is a Stock Split

When the number of shares held by investors is multiplied without altering the overall value of a business, it results in a stock split. The difference between a stock split and bonus issues is that in a bonus issue, the existing shareholders receive additional shares as a reward. Such actions ensure that the nominal value of shares while adjusting their quantity is maintained.

In a stock split, the trading price of individual shares is lowered, which allows the company to maintain its market cap while increasing the number of shares outstanding.

For investors, understanding the difference between bonus shares and a stock split helps them make strategic decisions concerning their investments.

Pros And Cons of a Stock Split

A stock split is a corporate action where a company increases the number of its outstanding shares by dividing existing shares, without changing its overall market value. While the share price adjusts proportionately, the move can influence investor perception, liquidity, and trading behaviour. Understanding both the advantages and limitations helps you interpret why companies choose to implement stock splits.

Pros of a stock split

  1. Improves affordability: A lower share price after a split makes the stock appear more accessible to retail investors, encouraging broader participation without changing the company’s fundamentals.
  2. Enhances liquidity: With more shares available at a lower price, trading volumes often increase, making it easier for investors to enter and exit positions.
  3. Positive market perception: Stock splits are often interpreted as a signal of management confidence in the company’s long-term growth, which can support investor sentiment.
  4. Wider investor base: A reduced share price can attract new categories of investors who may have been constrained by higher prices earlier.

Cons of a stock split

  1. No fundamental value change: A stock split does not improve earnings, cash flows, or business performance, even though it may create short-term excitement.
  2. Short-term volatility: Increased trading activity after a split can lead to price fluctuations, especially if expectations are driven by sentiment rather than fundamentals.
  3. Administrative and compliance costs: Executing a stock split involves regulatory filings, communication costs, and operational adjustments for the company.
  4. Misinterpretation risk: Some investors may incorrectly view a stock split as a value-enhancing event, leading to decisions based on perception rather than financial analysis.

Bonus Issue vs Stock Split: What Happens to the Share Price?

When a company announces a bonus issue or a stock split, the share price adjusts to reflect the increased number of shares, but the overall investment value remains unchanged.

In a bonus issue, existing shareholders receive additional shares free of cost in a fixed ratio, such as one bonus share for every two held. After the bonus, the share price falls proportionately because the company’s market capitalisation stays the same, while the number of outstanding shares increases. Your total holding value remains unchanged on the record date.

In a stock split, the face value of each share is divided, such as splitting one share of face value Rs. 10 into two shares of Rs. 5 each. The market price adjusts downward in the same ratio as the split. This makes shares more affordable and improves liquidity but does not alter the company’s fundamentals.

In both cases, the reduced share price reflects arithmetic adjustment rather than a real gain or loss for investors.

How does the share split vs bonus issue affect you as an investor?

Bonus shares and stock split are methods companies use to reward their shareholders without charging any form of additional payment. Here, we list the main points regarding bonus shares and a stock split so you can understand how they may affect you as a shareholder:

Meaning

  • Bonus issue: These are the additional shares offered to shareholders free of cost.
  • Stock split: This results in dividing the company's existing outstanding shares into multiple shares.

Example

  • Bonus issue: In a 2:1 bonus issue scenario, shareholders receive two shares free for every one share held. Thus, for 10 shares, investors will receive 30 (2 * 10 + 10) shares in total.
  • Stock split: In a 2:1 stock split ratio scenario, every share held by a shareholder becomes two shares. For every 50 shares held, the share count increases to 100 shares.

Face value

  • Bonus issue: No change occurs in terms of face value.
  • Stock split: Face value reduces in the same ratio as the split.

Company rationale

  • Bonus issue: This is considered an alternative to dividends and a means to distribute accumulated reserves to shareholders.
  • Stock split: This is aimed at increasing share liquidity, reducing share price, and making it more affordable for a larger spectrum of investors.

What is the company’s rationale?

A company’s rationale explains the underlying reasons behind a corporate action, such as a bonus issue or stock split. Typically, the objective is to improve share affordability and enhance market liquidity without altering the company’s overall valuation. By increasing the number of shares in circulation, the company aims to make its stock more accessible to a wider set of investors.

Another key reason is to signal confidence in long-term business prospects. Corporate actions often reflect management’s belief that earnings growth and operational performance can support a larger equity base. In some cases, such steps also help align the share price with industry peers or broader market expectations.

Additionally, companies may use these actions to reward existing shareholders without distributing cash, thereby preserving internal funds for expansion, debt reduction, or strategic investments. Overall, the rationale centres on improving market perception, participation, and long-term shareholder engagement while maintaining financial stability.

Final thoughts

Bonus shares and stock splits both raise the number of shares while lowering the market price per share. However, only a stock split changes the face value. Bonus issues reflect a transfer of reserves into share capital, whereas stock splits aim to improve affordability. Understanding these differences helps you make more informed investment decisions.

Frequently asked questions

Is a bonus issue good for investors?

A bonus issue can be beneficial because it increases the number of shares you hold without additional cost. Although it does not change the overall value immediately, it can improve liquidity, signal company confidence, and enhance long-term participation if the business continues to perform steadily.

Which is better, bonus or split share?

Neither option is inherently better. A bonus issue rewards existing shareholders by capitalising reserves, while a stock split improves affordability and liquidity by reducing the share price. The better option depends on the company’s objective and your investment perspective rather than short-term price movement.

Should I buy before or after a bonus issue?

Buying before a bonus issue does not automatically create gains because the share price adjusts proportionately. Your decision should depend on the company’s fundamentals, growth outlook, and valuation rather than the timing of the bonus announcement alone.

What are the disadvantages of a stock split?

A stock split does not change a company’s intrinsic value and may sometimes attract speculative trading. Increased volatility, higher retail participation without fundamentals, and misconceptions about affordability can create short-term price fluctuations without improving long-term business performance.
