supply and demand
The basis for an economic theory stating that when supply exceeds demand, the market value (price) of a product will drop and when demand exceeds supply, its value will rise. In the financial markets, the relationship between supply and demand is said to be reflected in selling price of a security, derivative, or debt instrument. See Efficient market Theory; free market system.
