A stock split or stock divide increases the number of shares in a public company. The price is adjusted such that the before and after market capitalization of the company remains the same and dilution does not occur. Options and warrants are included.

Take, for example, a company with 100 shares of stock priced at $50 per share. The market capitalization is 100 × $50, or $5000. The company splits its stock 2-for-1. There are now 200 shares of stock and each shareholder holds twice as many shares. The price of each share is adjusted to $25. The market capitalization is 200 × $25 = $5000, the same as before the split.

Ratios of 2-for-1, 3-for-1, and 3-for-2 splits are the most common, but any ratio is possible. Splits of 4-for-3, 5-for-2, and 5-for-4 are used, though less frequently. Investors will sometimes receive cash payments in lieu of fractional shares.

It is often claimed that stock splits, in and of themselves, lead to higher stock prices; research, however, does not bear this out. What is true is that stock splits are usually initiated after a large run up in share price. Momentum investing would suggest that such a trend would continue regardless of the stock split. In any case, stock splits do increase the liquidity of a stock; there are more buyers and sellers for 10 shares at $10 than 1 share at $100.

Other effects could be psychological. If many investors believe that a stock split will result in an increased share price and purchase the stock the share price will tend to increase. Others contend that the management of a company, by initiating a stock split, is implicitly signaling its confidence in the future prospects of the company.

In a market where there is a high minimum number of shares, or a penalty for trading in so-called odd lots (a non multiple of some arbitrary number of shares), a reduced share price may attract more attention from small investors. Small investors such as these, however, will have negligible impact on the overall price.

[edit] Reverse stock split

A reverse stock split, or reverse split, is just the same, but in reverse: a reduction in number of shares and an accompanying increase in the share price.[1] The ratio is also reversed: 1-for-2, 1-for-3 and so on.

There is a stigma attached to doing this so it is not initiated without very good reason. Many institutional investors and mutual funds, for example, have rules against purchasing a stock whose price is below some minimum, perhaps $5. An extreme case would be when a share price has dropped so low that it is in danger of being delisted from its stock exchange.

It is also possible that a reverse stock split could be used as a tactic to reduce the number of shareholders. In a hypothetical 1-for-100 reverse split any investor holding less than 100 shares would simply receive a cash payment and no shares of stock. If the resulting number of shareholders has then dropped below some threshold, it may be placed into a different regulatory category.

Typically, the stock will temporarily add a "D" to the end of its ticker during a reverse stock split.

[edit] Effect on historical charts

When a stock splits it is shown on many charts similar to a dividend payout. But when a stock splits it does not show the dramatic dip in price. Taking the same example as above, a company with 100 shares of stock priced at $50 per share. The company splits its stock 2-for-1. There are now 200 shares of stock and each shareholder holds twice as many shares. The price of each share is adjusted to $25. Based on this example you would expect that you would see the stock dropping 1 day from $50 to $25. This would cause chaos in the market as investors would panic if they did not take time to realize that there was a stock split. So what is done is something called adjusted close price. This adjusted close price will take all the closing prices before the split and divide them by the split ratio. So when you look at the charts it will seem as if the price was always $25. Both the Yahoo! historical price charts[2] and the Google historical price charts[3] show the adjusted close prices.
