What is a Stock Split?

Stock splits are a financial transaction used as a strategic tool by both companies and investors. Investors can make informed decisions aligned with their investment objectives by carefully examining these transactions.

A stock split is a financial transaction conducted by a company to increase or decrease its existing number of shares of stock. Companies typically resort to stock splits for reasons such as making the stock price per share more affordable, attracting more investors, or increasing the liquidity of the shares.

Forward Stock Split:

  • A forward stock split is an operation where a company increases its current number of shares of stock.

  • For example, a 2:1 forward stock split means that each investor will exchange each old share for two new shares.

  • Such splits aim to make stocks more accessible by reducing the price per share.

Reverse Stock Split:

  • A reverse stock split is an operation where a company decreases its current number of shares of stock.

  • For instance, a 1:5 reverse stock split implies that every five old shares will be replaced with one new share.

  • These types of splits aim to make stocks more attractive or meet listing requirements on specific stock exchanges by increasing the price per share.

How Does a Stock Split Work?

The process of a stock split typically occurs through a decision by the company’s board of directors and may be subject to shareholder approval. Whether forward or reverse, stock splits result in a change in the number of shares and an increase or decrease in the price per share.

For example, a 2:1 forward stock split means that two new shares will be issued for each existing share. This leads to an increase in the number of shares held by shareholders and a halving of the price per share. In contrast, a reverse stock split does the opposite by reducing the number of shares and increasing the price per share.

Stock splits are often seen as a strategy to attract investors or increase the liquidity of existing shares. However, it’s important to note that stock splits do not alter the fundamental value or financial health of the company; they merely adjust the stock’s structure.

Effects of Stock Split on Shareholders:

  • Number of Owned Shares:

After a stock split, the number of shares owned by shareholders increases. For example, in a 2:1 stock split, each shareholder will have 2 new shares for each existing share they held. This results in shareholders holding more shares in their portfolios.

  • Price per Share:

Following a stock split, the price per share decreases. For instance, in a 2:1 stock split, the price of each individual share is halved. This may be appealing to investors who prefer trading at a lower share price.

  • Total Investment Value:

A stock split does not alter the total investment value. An investor’s total value is calculated by multiplying the number of shares they own by the price per share. Therefore, even though the price per share decreases after a stock split, the increase in the number of shares owned keeps the total investment value the same.

Effects of Stock Split on the Company:

  • Market Capitalization:

A stock split does not impact a company’s market capitalization. Market capitalization is calculated by multiplying the price per share by the number of shares, and these two factors change inversely following a stock split.

For example, if the price per share decreases, the number of shares increases, and market capitalization remains the same. Conversely, if the price per share increases, the number of shares decreases, and market capitalization still stays the same.

  • Stock Price:

After a stock split, the stock price per share decreases. Lower stock prices make shares more accessible to investors.

Particularly for small investors, lower stock prices can make investing in shares more accessible.

  • Liquidity:

A stock split can contribute to increased liquidity of shares. Lower stock prices allow investors to buy and sell shares more easily.

Liquidity refers to how easily shares can be bought and sold in the market and is an important factor for investors.

Stock splits are typically undertaken by companies to make their shares more attractive and accessible. This process may encourage more trading in the stock market and pique the interest of new investors. However, changes in market capitalization and stock prices do not affect the fundamental value of the company; they only alter the stock’s structure. When deciding to implement a stock split, companies should carefully evaluate the potential benefits and consequences.

Advantages and Disadvantages of Stock Splits:

Advantages:

  • More Accessible Shares: Stock splits make shares more accessible by reducing the price per share. This allows small and retail investors to purchase shares more easily.

  • Increased Liquidity: Stock splits can encourage greater liquidity in shares. Lower share prices enable investors to buy and sell shares more frequently.

  • Attracting Investors: Lower share prices may attract investors considering investments in the company’s shares, potentially increasing demand for the company’s stock.

Disadvantages:

  • Misinterpretations: Despite the fact that a stock split lowers the share price, the company’s fundamental value remains unchanged. Nevertheless, some investors may misinterpret the drop in share price as a negative signal.

  • Costs: Stock split processes can incur costs for companies, particularly for larger corporations, involving additional expenses related to legal and financial processes.

  • Confusion in Investment Decisions: Stock splits can influence investors’ investment decisions. Investors should carefully examine the financial health and performance of the company after a stock split.

Key Takeaways:

  • A stock split is a financial transaction where a company increases or decreases its existing number of shares.

  • Companies may conduct stock splits to make the share price more attractive, attract more investors, or enhance share liquidity.

  • Stock splits increase the number of shares held by shareholders while decreasing the price per share.

  • The total investment value remains unchanged after a stock split, but shareholders have more shares in their portfolios.

  • A company’s market capitalization remains unchanged after a stock split, but the price per share decreases.


  • Stock splits can make shares more accessible and increase liquidity.
