What is 'Liquidity'. Liquidity describes the degree to which an asset or security can be quickly bought or sold in the market without affecting the asset's price. Market liquidity refers to the extent to which a market, such as a country's stock market or a city's real estate market, allows assets to be bought and sold at stable prices. Cash is the most liquid asset, while real estate, fine art and collectibles are all relatively illiquid.
From a trading perspective, liquidity is the ability of a security to be bought or sold without causing a significant movement in the price of the security. Liquid securities may be bought and sold in large numbers without a dramatic movement in the price of the security. The opposite is true for illiquid securities.
