Our study aims at this approach of beta estimation for establishing how beta coefficients for aggressive stocks prove to be more reliable than defensive stocks. Since Index Model is linear and envisages the premise of Simple Linear Regression, the researchers compare reliability of beta coefficients for aggressive and defensive stocks on the basis of R-squired statistic.
