Beta measures the sensitivity of a scrip movement relative to movement in the benchmark index i.e. SENSEX. A Beta of one means that for every change of 1% in index, the scrip moves by 1%. Statistically Beta is defined as: Covariance (SENSEX, Stock )/ Variance(SENSEX)
(Note: Covariance and variance are calculated from the Daily Returns data of the SENSEX and SENSEX scrips.)
