Beta is used in the capital asset pricing model (CAPM), which calculates the expected return of an asset based on its beta and expected market returns. Beta is also known as the beta coefficient.
The beta of two assets put together is aweighted average of the individual asset betas, with the weights based upon market value.Consequently, the beta for a firm is a weighted average of the betas of all of differentbusinesses it is in. Thus, the bottom-up beta for a firm, asset or project can be estimatedas follows.he weights remainthe same for all companies, and are not a function of the precision of the beta estimate. asset occurred at 2.30 pm and the index is measured at the close of trading at 4.00 pm, the measuredcorrelation between the asset and the index will be biased downwards.
