Elasticity of Demand

The relative stability of a security's or product's price in the face of increased or decreased demand. Elastic securities or products have prices that move as independently as possible from changes in demand. In securities, elasticity is strongly influenced by the number of shares outstanding; if a company has many shares outstanding, a large order to buy or sell them is less likely to affect the price as strongly as a similar order for a company with comparatively few shares outstanding. In other products, elasticity largely comes from whether a given product is considered a necessity or a luxury. A "necessary" product is likely to be more elastic. See also: Income Elasticity of Demand.


Of or relating to the demand for a good or service when the quantity purchased varies significantly in response to price changes in the good or service. For example, the demand for a product with many close substitutes is elastic because a small price rise will cause consumers to switch to competing brands. Compare inelastic.


adj. relatively responsive to change.
