Heres what happens. Amalgamated Kumquats, which is currently priced at $80 per share, announces a 2-for-1 stock split. If you own 100 shares before the split worth $8,000, you will own 200 shares worth $8,000 after the split.
The market automatically marks down the price of the stock by the divisor of the split. The $80 per share price becomes $40 per share.
There are other splits such as 3-for-1 and 3-for-2, however 2-for-1 seems the most common.
It terms of what your holdings are worth, nothing changes. In terms of what the company is worth, nothing changes. So, why do it?
- Perception Some companies worry when the per share price gets too high that it will scare off some investors, especially small investors. Splitting the stock brings the per share price down to a reasonable level.
- Liquidity If a stocks price rises into the hundreds of dollars per share, it may reduce the trading volume. Increasing the number of outstanding shares at a lower per share price aids liquidity.
Is it Good for Investors?Some investors say a stock split is a sign that a stock is doing well and they consider it a buy signal. I would caution reading too much into a stock split by itself.
You should always look at the whole picture before making an investment decision. If you want to use stock splits as a marker for stocks to consider for further evaluation, that is a reasonable idea, but dont stop there with your research.

CautionYou should watch out for one type of split as a possible danger signal and thats the reverse split.
In a reverse split, the company reduces the number of outstanding shares and the per share price rises accordingly.
For example, a company might execute a 1-for-2 reverse stock split, which means for every two shares you own, you would now own one and the per share price doubles.
A reverse stock split is often used to prop up a stocks price, since the price rises on the split. Often a company will do a reverse split to keep the stock price from falling below the minimum required by the stock exchange where it is listed.
Clearly, this is a sign that something is wrong if a company cant keep its stock price above the exchanges minimum listing price and caution is advised.
ConclusionWhen you paid stockbrokers based on the number of shares you purchased, it made sense to buy a stock before it split. However, most brokers now charge a flat fee, so timing a purchase before or after a split doesnt make much sense from that perspective.
Ultimately, you should buy a stock based on whether it meets the fundamental standards you require and not on whether it will or will not split.
