A stock split is when a company divides its existing shares into a larger number of shares, at a proportionally lower price per share. If you hold shares in a company that splits two for one, you end up with twice as many shares, each worth about half as much. The total value of your holding does not change.

What is a stock split?
Nothing about the company itself changes when it splits its stock. It does not make more money, own more assets, or become a different business overnight. A split is a structural change to how ownership is divided up, not a change to what the company is worth.
Here is a simple way to see it. Say you hold 10 shares priced at $50.00 each, for a total position of $500.00. After a two for one split, you hold 20 shares priced at $25.00 each. The total is still $500.00. The pie is cut into more slices, and each slice is smaller, but the size of the pie has not moved.
Companies usually announce a split ahead of time, and it applies automatically to existing shareholders on a set date. You do not need to buy or sell anything for it to take effect.

A related corporate action where a company reduces its share count instead of increasing it.
Why do companies split their stock?
Why do companies split their stock?
The most common reason is accessibility and liquidity. When a share price climbs high enough, buying a single share can feel out of reach for a lot of ordinary investors, and trading in smaller, cheaper units tends to bring in more buyers and sellers. A lower per-share price after a split can make a stock easier to trade for people managing a smaller amount of money.
Fractional share trading has reduced how much this motive matters. Where a high share price used to be a real barrier for someone without much capital, many brokers and apps now let people buy a fraction of a share, so a $500.00 stock and a $50.00 stock can both be bought with the same $20.00 budget. A split still tends to widen the pool of round-lot buyers, but it is no longer the only route to affordable access.
The other common reason is signalling. A company sometimes splits its stock after a strong run-up in price, as a way of projecting confidence in its own trajectory. This is a signal about how management wants the stock to be perceived, not a guarantee about what happens to the business next, and it should not be read as a forecast.
What is a reverse stock split?
What is a reverse stock split?
A reverse stock split works in the opposite direction. Instead of dividing shares into more, smaller pieces, a company combines existing shares into fewer, larger ones. If a company does a one for ten reverse split, 10 shares worth $2.00 each become 1 share worth about $20.00. The total value of the position again stays the same.
A reverse split tends to carry a different character than a forward split. Companies often use it to lift a share price that has fallen too low, sometimes to meet the minimum price required to stay listed on an exchange, or simply to make the stock look less distressed on a quote screen. That is not true in every case, but it is a common enough reason that a reverse split is generally read differently from a regular split.
The key point holds for both directions. Whether a company divides its shares into more or combines them into fewer, the action itself does not make the business more or less valuable. Value comes from how the company performs afterward, not from the arithmetic of the split.

FAQ
Does a stock split change how much your holding is worth?
No. A split changes your share count and the price per share by the same ratio, so the total value of your position stays the same immediately after the split. Any change in value after that comes from normal price movement, not from the split itself.
Do you have to do anything when a stock you hold splits?
Usually not. The split applies automatically to existing shareholders on the date the company sets, and your brokerage or app adjusts your share count and price accordingly.
Is a reverse stock split a bad sign?
Not always, but it is often used to lift a share price that has fallen too low, sometimes to meet an exchange's listing requirements. It is worth understanding why a specific company did it rather than treating every reverse split the same way.
