What is a stock split?

When companies decide to increase the no. of shares outstanding, the can do so by splitting the stock ‘2 for 1’ or ‘3 for 1’ or in any ratio that they deem fit. In case of a 3 for 1 stock split, a shareholder who owns 100 shares (say for company ABC) valued at $30 each gets 300 shares valued at $10 each after the 3 -1 stock split.

Please note that the total value of the shareholder’s holding does not change due to the stock split, i.e. 100 * $30 = 300 * $10 = $3000.


Effect of Stock Split on Earnings per share (EPS) and Price to Earnings (PE) ratio

Similarly, The earnings per share remain the same, the P/E ratio remains the same. For example if the earnings per share (EPS) for ABC company is $1.00 and there are 100 million shares currently priced at $30 each, PE = 30/1 = 30. After a 3 for 1 split, the number of shares become 300 million priced at $10 each, EPS goes down on $0.33, and PE = 10/0.33 = 30.

Why do companies split stocks?

Companies split their stocks primarily to make the share price affordable to more investors.

“We want Apple stock to be more accessible to a broader base of investors.

The decision to split the stock was made by Microsoft’s Board of Directors, based on a desire to make our stock more accessible to a broader range of investors

If the stock price is too high, say $3300 for 1 share of Amazon stock, many people will have to save up $3300 to buy 1 share. This can keep a lot of new and young investors away from investing in the company’s stock. Let’s say if Amazon does a 10 for 1 stock split, the new share price would be $330, making it affordable to many more investors.

The Era of Partial Shares or Fractional Shares

Nowadays you can buy partial shares of many stocks and ETFs. So, the rationale of making the stock accessible by lowering the price per share will become less relevant as more and more brokers offer this feature to their investors. You can buy partial shares on newer platforms such as Robinhood and M1 Finance. Some other brokers such as Fidelity and Schwab are also offering this opportunity to investors.

Reverse stock splits are done mostly when the stock price falls below a certain level, and the company wants to avoid being labelled a risky stock or even a penny stock (in case price falls below $1).

Example of a reverse stock split
