A situation in which buy orders for a particular security greatly outnumber...

Used for listed equity securities. Too many market orders of one kind -- to buy or to sell or limit orders to buy up or sell down, without matching orders of the opposite kind. An imbalance usually follows a dramatic event such a takeover, research recommendation, death of a key executive, or a government ruling that will significantly affect the company's business. If it occurs before the stock exchange opens, trading in the stock is delayed. If it occurs during the trading day, the specialist halts and then suspends trading (with floor governor's approval) until enough matching orders can be found to make an orderly market.

Used for listed equity securities. Defines the situation when the market is confronted with too many market orders of one kind for a certain asset (to buy or to sell) or limit orders (to buy up or sell down), which greatly outnumber the existing orders of opposite kind. This situation is usually the result of a dramatic event (takeover, research recommendation, or death of a key executive). May result in a temporary trading halt for that security, until enough matching orders can be found.
