Beta: The systematic risk indicator

Beta measures how much a stock moves relative to the overall market. A beta of 1 means the stock follows the market; greater than 1, it's more volatile; less than 1, it's more stable.

Beta is a number reflecting a security's sensitivity to market index movements.

Beta doesn't predict the future; it only describes past behavior.
