Stock split vs bonus share – Basics of stock market

Most of the beginners are confused about stock split vs bonus share. Whenever they hear that one of their holding stock is going to split or is giving a bonus share, they do not understand what does this mean and how this will affect their investment.

As both results in an increase in the quantity of stocks and adjustment of share price, most beginners are confused whether they are same or different.

Further, they do not understand why company announces stock split or bonus share. What is the basic difference between them?

Therefore, in this post, I’m going to explain you the difference between stock split vs bonus share with the help of few past examples from Indian share market.

Be with me for the next 5-6 minutes to understand this basic of the stock market.

Past example of stock split vs bonus share:

  • Stock Split

Yes bank split its share in the ratio of 1:5 on 26th July 2017. This means that every shareholder who has 1 share of Yes bank, had got 5 shares in total.

If you were holding 30 shares of yes bank, you would have got a total of 150 shares.

You might be thinking- ‘Awesome, I got extra shares for free!!’.

However, after the stock split, the share price of the stock also splits in the same ratio. Here is the chart of yes bank after the stock split.

Please notice that the stock price of Yes Bank changed from Rs 1880 to Rs 376 after the split.

Why does this happen and what is the impact of the stock split on its shareholders? This we will study in next section in this post.

  • Bonus Share

Now, let us see an example of bonus shares.

Hindustan petroleum corporation limited (HPCL) announced bonus shares to its shareholders in two consecutive years.

First, on 20th July 2016 in the ratio of 2:1.
Second, on 26th May 2017 in the ratio of 1:2.

Announcement Date Bonus Ratio Record Date Ex-Bonus Date
26-05-2017 1:2 12-07-2017 11-07-2017
20-07-2016 2:1 15-09-2016 14-09-2016

In the first case, the shareholders got 2 shares for every 1 share in their portfolio.
In the second case, the shareholders got 1 share for every 2 shares in their portfolio.

If you notice the stock chart of HPCL on google, you cannot identify the bonus stock dates.

Unlike stock split, you cannot decide the bonus given by the share chart as there are no sharp spikes on the chart. In the bonus share, the stock prices are automatically adjusted.

However, if you check the chart on money control, you can notice two bonuses of the share of HPCL.

Stock split vs bonus stock

We will first understand bonus shares. We will define some financial terms here, which we are also going to use later in the post.

1. Bonus Shares:

Bonus shares are the additional shares given to the shareholders by the company. This is a method of rewarding the shareholders.

How does a company give the bonus?

Companies accumulate its profits in the reserve fund. During bonus share, these reserve funds are converted into share capital and distributed among its shareholders as a bonus.

In short, when a company gives bonus shares, it’s share capital increases while its reserve fund decreases.

Why companies give a bonus?

Here are the few reasons why company gives a bonus to its shareholders:

  • For rewarding its shareholders.
  • To improve the liquidity and hence, the total trading volume of the stock.
  • To decrease the share price and to make it more affordable for retail investors.
  • It increases the confidence of the shareholders towards the company.

Impact of bonus shares on shareholders:

Although a bonus share is a positive news for the shareholders, however, it doesn’t affect their investment amount much. After the bonus is given, the share price of the company will fall in the same proportion.

Therefore, there will be no noticeable difference in the wealth of shareholder.

2. Stock Split:

In a stock split, the company splits the share price into different parts.

For example, in a stock split of 1:1, stock price splits into two parts.
In a stock split of 1:5, stock splits into 5 parts.

The fundamentals of a company remain same in a stock split. There is neither increase or decrease in the share capital or reserve in a stock split.

You can remember stock split as splitting the pieces of pizza. You can split the 4 pieces of pizza into 8, however the overall pizza will be the same.

Why company split stocks?

Here are the few reasons why company split its share:

  • To increase the liquidity of the stock and increase the trading volume.
  • To make the stock more affordable for the retail investors.

Impact of the stock split on shareholders:

There won’t be much impact on the personal wealth of the shareholder.

1 stock of Rs 10,000 or 5 stocks of Rs 2,000; both are same for the existing shareholders.

NOTE: During a stock split, EPS (Earnings per share) decreases in the same factor as stock split (because the earnings will be same, but the number of outstanding shares will increase). Hence, the price to earnings (PE) ratio will remain the same (as both Price and EPS decreases by the same factor).

Example: Stock split vs bonus share

Assume there is a company, ABC. This company is currently trading in the market at a stock price of Rs 100.


Face value of each share = Rs 10.

Total number of outstanding shares = 10,000

Reserve capital = Rs 5,00,000

Now, the market capitalization of the company ABC

= (No of outstanding shares)*(Market price of 1 share)

= (10,000)* (Rs 100)

= Rs 10,00,000 {10 lakhs}

Case 1: Bonus shares

Now, let us assume that the company has announced a bonus share of 1:1.

Company will give an addition share of 10,000 to its existing shareholders.

Total number of outstanding share = 2*10,000 = 20,000

Decrease in reserve capital = 10 * 10,000 = Rs 1,00,000

Net reserve capital for the company = Rs 5,00,000 – Rs 1,00,000 = Rs 4,00,000

As the market capitalization will remain the same after the bonus share, hence the market value of the stock = 10,00,000 / 20,000 = Rs 50.

Case 2: Stock split

Let us assume that the company makes a stock split of 1:1 (in place of the bonus share).

Hence, the market value of stock after split = Rs 50 {Originally Rs 100, split in ratio of 1:1)

Here are the changes on different parameters due to stock split vs bonus share:

Originaly Stock Split (1:1) Bonus share (1:1)
Stock Price Rs 100 Rs 50 Rs 50
Face Value Rs 10 Rs 5 Rs 10
Outstanding share 10,000 20,000 20,000
Market Capitalization Rs 10,00,000 Rs 10,00,000 Rs 10,00,000
Reserve capital Rs 5,00,000 Rs 5,00,000 Rs 4,00,000

Please note that the face value of a stock also splits during the stock split and the reserve capital decreases in bonus share.

The stock price will automatically be adjusted on both stock split and bonus share on the day of implementation.


Stock split vs bonus stock

In simple words, a stock split is the split of same stock into many parts while the bonus is free additional shares.

Stock price and outstanding shares changes in both stock split and bonus share.

While share split has no impact on the fundamentals of the company, on the other hand, reserve capital decreases in bonus share.

Bonus share is taken positively by the shareholders while there is no impact of the stock split on the shareholders.
