What Is a Stock Split?
A stock split is when a company divides the existing shares of its stock into multiple new shares to boost the stock's liquidity. Although the number of shares outstanding increases by a specific multiple, the total dollar value of the shares remains the same compared to pre-split amounts, because the split does not add any real value.
The most common split ratios are 2-for-1 or 3-for-1 (sometimes denoted as 2:1 or 3:1), which means that the stockholder will have two or three shares after the split takes place, respectively, for every share held prior to the split.

Understanding Stock Splits
How a Stock Split Works
A stock split is a corporate action in which a company divides its existing shares into multiple shares. Basically, companies choose to split their shares so they can lower the trading price of their stock to a range deemed comfortable by most investors and increase the liquidity of the shares.
Most investors are more comfortable purchasing, say, 100 shares of $10 stock as opposed to 10 shares of $100 stock. Thus, when a company's share price has risen substantially, many public firms will end up declaring a stock split at some point to reduce the price to a more popular trading price. Although the number of shares outstanding increases during a stock split, the total dollar value of the shares remains the same compared to pre-split amounts, because the split does not add any real value.
When a stock split is implemented, the price of shares adjusts automatically in the markets. A company's board of directors makes the decision to split the stock into any number of ways. For example, a stock split may be 2-for-1, 3-for-1, 5-for-1, 10-for-1, 100-for-1, etc. A 3-for-1 stock split means that for every one share held by an investor, there will now be three. In other words, the number of outstanding shares in the market will triple.
On the other hand, the price per share after the 3-for-1 stock split will be reduced by dividing the price by three. This way, the company's overall value, measured by market capitalization, would remain the same.
Market capitalization is calculated by multiplying the total number of shares outstanding by the price per share. For example, assume that XYZ Corp. has 20 million shares outstanding and the shares are trading at $100. Its market cap will be 20 million shares x $100 = $2 billion. Let's say the company’s board of directors decides to split the stock 2-for-1. Right after the split takes effect, the number of shares outstanding would double to 40 million, while the share price would be halved to $50, leaving the market cap unchanged at 40 million shares x $50 = $2 billion.
In the UK, a stock split is referred to as a scrip issue, bonus issue, capitalization issue, or free issue.
Reasons for a Stock Split
Why do companies go through the hassle and expense of a stock split? For a couple of very good reasons. First, a split is usually undertaken when the stock price is quite high, making it expensive for investors to acquire a standard board lot of 100 shares.
Second, the higher number of shares outstanding can result in greater liquidity for the stock, which facilitates trading and may narrow the bid-ask spread. Increasing the liquidity of a stock makes trading in the stock easier for buyers and sellers. Liquidity provides a high degree of flexibility in which investors can buy and sell shares in the company without making too great an impact on the share price. Added liquidity can reduce trading slippage for companies that engage in share buyback programs. For some companies, this can mean significant savings in share prices.
While a split, in theory, should have no effect on a stock's price, it often results in renewed investor interest, which can have a positive impact on the stock price. While this effect can be temporary, the fact remains that stock splits by blue-chip companies are a great way for the average investor to accumulate an increasing number of shares in these companies.
Many of the best companies routinely exceed the price level at which they had previously split their stock, causing them to undergo a stock split yet again. Walmart, for instance, has split its shares as many as 11 times on a 2-for-1 basis from the time it went public in October 1970 to March 1999. An investor who had 100 shares at Walmart’s initial public offering (IPO) would have seen that little stake grow to 204,800 shares over the next 30 years.
Example of a Stock Split
In August 2020, Apple (AAPL) split its shares 4-for-1 to make it more accessible to a larger number of investors. Right before the split, each share was trading at around $540. After the split, the price per share at the market open was $135 (approximately $540 ÷ 4).
Existing shareholders were also given four additional shares for each share owned, so an investor who owned 1,000 shares of AAPL pre-split would have 4,000 shares post-split. Apple's outstanding shares increased from 3.4 to approximately 13.6 billion shares, however, the market cap remained largely unchanged at $2 trillion.
Stock Split vs. Reverse Stock Splits
A traditional stock split is also known as a forward stock split. A reverse stock split is the opposite of a forward stock split. A company that issues a reverse stock split decreases the number of its outstanding shares and increases the share price. Like a forward stock split, the market value of the company after a reverse stock split would remain the same. A company that takes this corporate action might do so if its share price had decreased to a level at which it runs the risk of being delisted from an exchange for not meeting the minimum price required to be listed. A company might also reverse split its stock to make it more appealing to investors who may perceive it as more valuable if it had a higher stock price.
A reverse/forward stock split is a special stock split strategy used by companies to eliminate shareholders that hold fewer than a certain number of shares of that company's stock. A reverse/forward stock split uses a reverse stock split followed by a forward stock split. The reverse split reduces the overall number of shares a shareholder owns, causing some shareholders who hold less than the minimum required by the split to be cashed out. The forward stock split increases the overall number of shares a shareholder owns.
What happens if I own shares that undergo a stock split?
When a stock splits, it credits shareholders of record with additional shares, which are reduced in price in a comparable manner. For instance, in a typical 2:1 stock split, if you owned 100 shares that were trading at $50 just before the split, you would then own 200 shares at $25 each. Your broker would handle this automatically, so there is nothing you need to do.
Will a stock split impact my taxes?
No. The receipt of the additional shares will not result in taxable income under existing U.S. law. The tax basis of each share owned after the stock split will be half of what it was before the split.
Are stock splits good or bad?
Stock splits are generally done when the stock price of a company has risen so high that it might become an impediment to new investors. Therefore, a split is often the result of growth or the prospects of future growth, and is a positive signal. Moreover, the price of a stock that has just split may see an uptick as new investors seek the relatively better-priced shares.
Does the stock split make the company more or less valuable?
No, splits are neutral actions. The split increases the number of shares outstanding, but its overall value does not change. Therefore the price of the shares will adjust downward to reflect the company's actual market capitalization. If a company pays dividends, new dividends will be adjusted in kind. Splits are also non-dilutive, meaning that shareholders will retain the same voting rights they had prior to the split.
Can a stock split be anything other than 2-for-1?
While a 2:1 stock split is the most common, any other ratio may be carried out so long as it is approved by the company's shareholders and board of directors. These may include, for instance, 3:1, 10:1, 3:2, etc. In the last case, if you owned 100 shares you would receive 50 additional shares post-split.
