(redirected from break-out)
Also found in: Dictionary, Thesaurus, Medical, Idioms, Encyclopedia.


A rise in a security's price above a resistance level (commonly its previous high price) or a drop below a level of support (commonly the former lowest price.) A breakout is taken to signify a continuing move in the same direction. Can be used by technical analysts as a buy or sell indicator.


1. In technical analysis, a situation in which the price of a security rises above a resistance level. The resistance level is a price above which a security only rarely climbs. This is a highly bullish signal because it indicates the price likely will continue to rise until it finds another resistance level.

2. In technical analysis, a situation in which the price of a security falls below a support level. The support level is a price below which a security only rarely drops. This is a highly bearish signal because it indicates the price likely will continue to fall until it finds another support level.

The advance of a stock price above a resistance level, or the fall of a stock price below a support level. A breakout, especially one on relatively heavy volume, indicates to technicians that the security is about to make a major price movement in the direction indicated by the breakout. Thus, if a breakout is upward, a major upward price movement can be expected. A breakout on relatively low volume is suspect. See also break through, congestion area.


Stock prices fluctuate constantly, but each stock typically moves within a fairly narrow range. That means the stock's average price changes gradually, if at all. But sometimes a stock's price breaks out of its limits, and jumps or tumbles suddenly.

Usually the breakout is fueled by a particular event. The company may realize a commercial success, such as a drug company discovering a new cure for a major disease. Or a breakout may reflect a financial development, such as a new alliance with a successful partner.
