An increase in the price of a security when another company in the same or a similar sector is acquired by a third company. For example, if Holding Company A buys Mining Corporation B, garbatrage occurs when the share price for Mining Corporation C goes up. Garbatrage occurs when speculation surrounds the initial acquisition and rumors abound that more takeovers are likely. It is also called rumortrage and is an example of behavioral economics.
