Companies split their stock to adjust the way ownership is represented in the market by increasing the number of shares outstanding and lowering the price per share, while leaving the company’s total market value unchanged.
Stock splits are typically considered after a prolonged increase in a company’s share price. As prices rise, trading can become less efficient, and participation may narrow as standard trade sizes become more expensive.
A stock split recalibrates the share structure, placing the stock back into a price range that management believes supports healthy liquidity and broader market participation.
This article explains why stocks split, how stock splits work from a structural perspective, and how investors should interpret them within a long-term investment framework.
Key Takeaways
- Stock splits modify share structure without changing a company’s economic value or investor ownership.
- Companies use splits to support liquidity, trading efficiency, and broader market participation.
- For investors, stock splits are informational events and should be evaluated alongside business fundamentals, not treated as value-creating actions.
What Exactly Is a Stock Split?
A stock split is a corporate action in which a company increases its number of outstanding shares by dividing each existing share into multiple new shares according to a fixed ratio.
At the same time, the market price per share is adjusted downward by the same ratio so that the company’s TOTAL MARKET CAPITALIZATION AND EACH INVESTOR’S PROPORTIONAL OWNERSHIP REMAIN UNCHANGED.
For example:
- In a 2-for-1 stock split, one share becomes two shares and the price per share is reduced by half
- In a 10-for-1 stock split, one share becomes ten shares and the price per share is reduced to one-tenth
After the split, investors hold a greater number of shares, each priced lower, while the total value of their investment remains the same. The split changes how ownership is represented and traded in the market, but it does not affect earnings, cash flow, assets, or the company’s underlying business operations.
From an accounting and economic perspective, a stock split is a structural adjustment, not a value-creating event. It alters the denomination of ownership without altering the substance of that ownership.
Examples of High-Profile Stock Splits
Below are several well-known examples showing how large public companies have used stock splits as a share-structure adjustment, not a change in underlying business value.
- Netflix (NFLX): Netflix implemented a 10-for-1 stock split that took effect on November 17, 2025. The split adjusted Netflix’s share price from roughly $1000 per share to about $100, while increasing the number of shares held by investors by a factor of ten. This action followed a period of strong share price appreciation and was designed to place the stock into a more accessible trading range, without changing Netflix’s total market value or investor ownership.
- Broadcom (AVGO): Broadcom announced a 10-for-1 stock split effective in July 2024. This action adjusted its market price per share from approximately $1,200 to $120, increasing the number of shares held by investors tenfold. This is a clear example of a company using a split to enhance the psychological affordability of its stock and potentially increase market interest.
- Apple Inc. (AAPL): As a technology leader and a major component of the S&P 500, Apple has conducted multiple high-profile stock splits in its history. On June 9, 2014, Apple executed a 7-for-1 stock split, reducing its share price from around $645 to approximately $92. Later, on August 31, 2020, Apple conducted a 4-for-1 stock split, lowering the price from roughly $500 to about $125. Apple is a widely recognized example of a company that has used splits to make its shares more accessible and appealing to a broader investor base, contributing to its strong market capitalization.
- Amazon (AMZN): Another mega-cap technology firm, Amazon has also executed significant stock splits. On June 6, 2022, Amazon completed a 20-for-1 stock split, reducing its share price from around $2,400 to approximately $120. Its shares, which were once very high-priced, became more accessible to individual investors through splits, complementing the availability of fractional investing at brokerages.
Why Stocks Split
One of the primary reasons companies choose to split their stock is to reset the share price to a more accessible level after a prolonged period of appreciation. As a stock’s price rises, buying even a single share can feel increasingly expensive to individual investors, despite the availability of fractional shares.
By lowering the market price per share through a stock split, companies aim to achieve several practical outcomes:
- Increase psychological affordability: A lower nominal share price can make a stock appear more accessible and attractive to small-scale investors. For an investor with limited capital, purchasing shares at $120 might feel more attainable than buying shares at $1,200, even if fractional investing is an option.
- Expand the investor base: A more accessible share price can encourage more retail investors to purchase the stock, potentially increasing the overall market demand and market liquidity for the company’s shares. Lowering the per-share price can, as a practical matter, contribute to greater trading volatility by making shares more digestible for a wider array of market participants.
- Support liquidity and trading activity: With more shares outstanding and a lower per-share price, stocks often trade in smaller, more frequent increments. This can improve liquidity and make it easier for investors to enter and exit positions efficiently.
It is important to note that this form of affordability is perceptual rather than economic. A stock split does not change the company’s intrinsic value, earnings power, or growth prospects. However, market behavior is influenced by perception, and changes in share price presentation can affect trading dynamics. While bid–ask spreads may briefly adjust around the time of a split, liquidity typically normalizes as the market absorbs the new share structure.
How Stock Splits Affect Investors
For investors, the immediate impact of a stock split is mechanical rather than financial. While the number of shares owned increases and the price per share decreases, the total value of the investment remains the same at the moment the split takes effect.
Stock Splits Impact on Existing Shareholders
If you already own shares of a company that announces a stock split, the split results in:
- A higher share count, based on the split ratio
- A lower price per share, adjusted proportionally
- No change in total investment value immediately after the split
For example, in a 10-for-1 stock split, an investor holding 100 shares would own 1,000 shares after the split, with the share price reduced to one-tenth of its previous level. The overall value of the holding remains unchanged at the time of the split.
Stock Splits Impact on New Investors
For prospective investors, stock splits can make it easier to initiate a position, particularly for those who prefer buying whole shares. A lower nominal share price can reduce psychological barriers to entry, even though fractional shares already allow precise dollar-based investing.
This increased accessibility can lead to higher trading activity and greater investor participation, especially among retail investors.
Stock Splits Effect on Dividends
In most cases, companies adjust dividend payments proportionally after a stock split. While the dividend per share decreases, the total dividend income an investor receives typically remains the same, assuming the dividend policy does not change.
Investors focused on income should continue to evaluate dividend sustainability, payout ratios, and cash flow rather than the post-split dividend amount alone.
Tax Considerations
Stock splits are generally not taxable events. They do not create immediate capital gains or losses. Instead, an investor’s cost basis per share is adjusted to reflect the new share count, preserving the total cost basis of the investment. Taxes are only triggered when shares are sold.
Long-Term Implications
From a long-term perspective, stock splits do not alter a company’s fundamentals, competitive position, or growth outlook. Any post-split price movement reflects market behavior rather than intrinsic value changes.
For disciplined investors, the key takeaway is to treat stock splits as informational events, not investment signals. Long-term performance continues to depend on earnings growth, cash flow generation, and sound capital allocation.
A Long-Term Investor’s Perspective on Stock Splits
While stock splits are a common corporate action often met with enthusiasm, the discerning investor approaches them with a broader perspective. The initial excitement surrounding a stock split, driven by the perception of affordability, can sometimes overshadow the more profound reality that a company’s fundamental worth remains unaltered.
For an investor steeped in the principles of value investing, championed by figures like Benjamin Graham and Warren Buffett, the intrinsic value of a business is paramount. This intrinsic value is rooted in a company’s financial fundamentals, projected earnings & cash flow growth, and operational efficiency, not merely its market price per share. From this viewpoint, a stock split is akin to cutting a pie into more slices; the pie itself, its quality, and its overall size remain the same. The investor focused on genuine value understands that the strength of the business model, consistent earnings, healthy cash flow, and rational valuations are the true determinants of long-term success.
Warren Buffett attributes his extraordinary success to a disciplined habit of reading and an investment philosophy grounded in intellectual curiosity and a relentless focus on intrinsic value. His approach, often associated with Berkshire Hathaway, emphasizes buying businesses he understands, managing risk carefully, and focusing on fundamentals like cash flow and earnings quality. Relying solely on a stock split as a reason to invest, without a thorough analysis of the underlying business, would be akin to prioritizing surface-level metrics over the deep analysis that truly informed investment decisions demand. Therefore, while a split might widen accessibility or influence short-term trading volatility or market shifts, it is the company’s core business performance and its alignment with fundamental investment principles that ultimately matter for building lasting wealth.
The Bottom Line on Stock Splits
Understanding why stocks split reveals a common corporate strategy aimed at managing share price perception and enhancing market accessibility, rather than signaling an immediate change in core business value. While the number of shares outstanding increases and the per-share price decreases proportionally, the fundamental value of your holdings remains consistent.
For investors, the key insight is to look beyond the surface-level adjustment of a stock split. True long-term success in the market is built upon a disciplined approach that prioritizes rigorous fundamental analysis, focusing on a company’s intrinsic value, robust financial health, and consistent earnings power. With tools like Gainify, investors can conduct comprehensive research, screening for companies with strong fundamentals and aligning investment decisions with their long-term investment goals, rather than getting swayed by nominal price changes or technical factors alone.
FAQs: Understanding Stock Splits
Q: Does a stock split make a company more valuable?
A: No, a stock split does not inherently make a company more valuable. While it changes the number of shares and the market price per share, the company’s total market capitalization and your total investment value in the company remain the same immediately after the split.
Q: Is a stock split a good sign for investors?
A: A stock split is often perceived as a positive sign because companies typically execute splits when their stock price has increased significantly, indicating strong past performance and growth prospects. However, the split itself is a mechanical adjustment and does not guarantee future performance. Investors should focus on the company’s fundamentals and future outlook.
Q: How does a stock split affect existing shareholders?
A: For existing shareholders, a stock split increases the number of shares they own and proportionally decreases the price of each share. For example, in a 10-for-1 split, an investor would own ten times more shares, but each share would be worth one-tenth of its pre-split price, leaving the total value of their holding unchanged.
Q: Do stock splits affect fractional shares?
A: Yes, if you own fractional shares, they will also undergo the split in the same proportion. For instance, if you own 0.5 of a share and the company has a 2-for-1 split, you would then own 1 full share. Fractional investing already makes high-priced stocks accessible to everyday investors, even without a split.
Q: Will I earn more dividends after a stock split?
A: Not necessarily. While you will own more shares, the company usually adjusts its dividend payments per share proportionally to the split. This means your total dividend payout often remains the same, although some companies might choose to slightly increase the total payout as a gesture of confidence. Investors should monitor dividend growth and the dividend payout ratio to assess sustainability.
Q: How do stock splits relate to investment vehicles like mutual funds and exchange-traded funds?
A: If a stock held within a mutual fund or an exchange-traded fund undergoes a split, the fund’s holdings are automatically adjusted to reflect the new number of shares and their proportional price change. This means that the fund’s overall value and your investment in the fund remain unaffected by the individual stock’s split. These funds provide diversified exposure to the broad market and individual companies without the need to directly manage the impact of corporate actions like splits on your own.
Q: Do stock splits involve any specific regulatory rules?
A: While stock splits are common corporate actions, they are subject to certain regulatory rules and reporting requirements set by financial authorities to ensure transparency and proper disclosure to shareholders. Companies typically announce their split ratios and effective dates well in advance, allowing for an orderly market reaction.
