A situation in which many investors buy a security on high volume, leading to a rapid rise in price. Panic buying usually occurs when investors believe that a security or market is already rising and they wish to buy it before the price rises even more. Panic buying may or may not be the result of an overreaction. Rules on many stock markets limit the amount by which a security can rise in a single session to reduce the pressure for panic buying. See also: Panic selling.
A flurry of security purchases accompanied by high volume and sharp price increases. During a period of panic buying, buyers do not have time to evaluate fundamental or technical factors because their primary goal is to acquire securities before the prices rise even more. For example, panic buying occurred on the day following President Lyndon B. Johnson's announcement of his decision not to run for reelection.
