dumping

1. The selling of large amounts of a stock, or stocks in general, at whatever market prices are in effect. For example, investors might dump stocks on hearing of an outbreak of fighting in some part of the world.
2. The selling of a product in one market at an unusually low price while selling the same product at a significantly higher price in another market. For example, a firm may sell a product in its home market at a price covering all costs, and then sell the product in a foreign market at a significantly lower price, covering only variable costs.
