DEFINITION of 'Reverse Stock Split'

A corporate action in which a company reduces the total number of its outstanding shares. A reverse stock split involves the company dividing its current shares by a number such as 5 or 10, which would be called a 1-for-5 or 1-for-10 split, respectively. A reverse stock split is the opposite of a conventional (forward) stock split, which increases the number of shares outstanding. Similar to a forward stock split, the reverse split does not add any real value to the company. But since the motivation for a reverse split is very different from that for a forward split, the stock’s price moves after a reverse and forward split may be quite divergent. A reverse stock split is also known as a stock consolidation or share rollback.
