A reverse stock split is when a company decreases the number of shares outstanding in the market by canceling the current shares and issuing fewer new shares based on a predetermined ratio. For example, in a 2:1 reverse stock split, a company would take every two shares and replace them with one share. A reverse stock split results in an increase in the price per share.

stock split, on the other hand, is when a company increases the number of shares outstanding by splitting them into multiple shares. This results in a decrease in the price per share. In a 2:1 stock split, each share of stock would be split into two shares.

Are There Typical Ratios For Reverse Stock Splits?

Common share swap ratios used in a reverse stock split are 2:1, 10:1, 50:1, and 100:1. There is no set standard or formula for determining a reverse stock split ratio. Ultimately, the ratio chosen depends on the stock share price that the company ultimately wants its shares to trade at on the exchanges.

Example of a Reverse Split

A company announces a reverse stock split of 100:1. All investors will receive 1 share for every 100 shares they own.

So if you owned 1,000 shares at a stock price of 50 cents per share before the reverse split, you would own 10 shares at a price of $50 each after the reverse split. The value of your holdings was $500 before the split (1,000 shares at 50 cents each) and $500 after the split (10 shares at $50 each).

However, some investors can be cashed out of their positions if they own a small number of shares. For example, if an investor owns 50 shares of a company that splits 100:1, the investor would be left with only half a share, so the company would pay that investor the value of the 50 shares.

A reverse stock split causes no change in the market value of the company or market capitalization because the share price also changes. So, if the company had 100 million shares outstanding before the split, the number of shares would equal 1 million following the split.

Why Would a Company Do a Reverse Split?

1. To prevent its stock from being delisted by boosting its share price. Being listed on a major exchange is considered an advantage for a company in terms of attracting equity investors. If a stock price falls below $1, the stock is at risk of being delisted from stock exchanges that have minimum share price rules. Reverse stock splits boost the share price enough to avoid delisting.

2. To boost the company's image. Typically, stock with a share price in the single digits is seen as risky. As its price approaches $1, a stock may be seen as a penny stock by investors. A company may try to protect its brand by avoiding the penny stock label and engage in a reverse split. There is a negative stigma typically attached to penny stocks traded only over-the-counter.

3. To get more attention from analysts. A company may not be in danger of being delisted, but it may nonetheless wish to increase its share price to attract more attention from analysts and investors. Higher-priced stocks tend to attract more attention from market analysts.

4. To avoid delisting from options exchanges. Typically, a company's share price must be greater than $5 for options to be traded on the stock. If a company's stock price falls too low for options to be traded on it, the shares might lose interest from hedge funds and institutional investors who invest billions of dollars in the market and hedge their positions via options. If portfolio managers can't hedge their long positions (due to delisting from an options exchange), they may sell the stock.
