What is stock split?

A stock split is:

  1. when a company’s board of directors issue more shares
  2. issued to current shareholders
  3. when the current value of a shareholder’s stake is not diluted

It basically eases the total number of shares outstanding for a company and reduces the value of each share. So, although the total number of shares outstanding increases, the company’s valuation and the value of a shareholder’s stake in the company does not change.

Here’s an example to understand this:

Suppose you have one share of company ABC’s stock. If the company announces a 2-for-1 stock split, it will allot you an additional share. However, each share will now be valued at half the amount of the original value. Thus, post the split, the two shares you own will be worth the same as the one share you earlier had.

How is Stock Split calculated?

Shareholders who wish to estimate the total number of shares that they will own after a stock split can use the following formula:

Total number of shares post stock split = number of shares held * number of new shares issued for each existing share.

For example, you currently own 150 shares of a company that has announced a split ratio of 2:1. The total number of shares you will own after the stock split will be:

=150 X 2


Calculating stock price after stock split

If you want to know the share price after a stock split, the following formula can be used:

New stock price = Old stock price/Stock split ratio

Thus, if a stock you own was last traded at a price of Rs.100 and the company has announced a stock split of 3:1, the new price of the stock will be:

= 100 /(3:1)

= 33.33

Why do companies announce split their stocks?

Here are some of the common reasons for this:

Higher liquidity

One of the main reasons why companies announce stock splits is to attain higher liquidity. In many cases, the company’s share price may be too high for investors to easily buy them. Any additional price rise may further discourage investors from participating in the company’s shareholding. By decreasing the value of a stock through a stock split, the shares can be made accessible to a larger investor population, thereby resulting in higher liquidity.

Wider stockholder base

Through this corporate action, a company can add on to the number of its outstanding shares and offer an opportunity to a wider investor base to buy its shares. This helps the company to increase its stockholder base.

Future growth perception

Companies that announce stock splits are generally perceived to be in the growth phase. Such announcements are considered by investors as an indication of the company’s intent to attain growth. This helps in creating a positive market image about the company.

Disadvantages of a Stock Split

Some of the disadvantages of stock split are:

  • Reduced liquidity: Stock splits can increase the number of shares outstanding, potentially decreasing liquidity and making it harder to buy or sell shares.
  • Lower price per share: The reduced share price after a stock split may attract more retail investors, leading to increased volatility and potential market manipulation.
  • Market perception: Some investors view stock splits as a signal of overvaluation, which could affect the stock’s perceived value and future performance.
  • Transaction costs: Investors may incur additional transaction costs, such as brokerage fees, when buying or selling a higher number of shares.
  • Psychological impact: Stock splits can create short-term excitement, but they don’t fundamentally change a company’s value, and investors should focus on underlying fundamentals rather than just the split.

The table below highlights the key differences between these two:

Stock splits can fetch greater returns for companies. It is seen as an indication of good performance of a stock and therefore helps in an increased price in the future. As per historical evidence, many stocks that have undergone a split are known to become profitable for investors in the long run.
