The risk that an individual or firm will have difficulty selling an asset without incurring a loss. That is, there may be a lack of interest in the market for a particular asset, forcing the owner to sell it for less than its actual value. Liquidity risk may be quantified as the difference between an asset's value and the price at which it can likely be sold. It is highest for lightly traded securities and small issues, as well as during a bear market.
