A measure of an asset’s systematic risk in comparison to the market as a whole, typically being the regression coefficient between historical dividend-adjusted returns of a security and market returns, where an asset with a coefficient of 1.0 denotes the same level of risk as the overall market and that its price will move in direct proportion to the market.
