This paper provides an assessment on the systematic risk in the equity capital markets of Pakistan. We investigate the possibility of time varying betas in Pakistan using three estimation techniques: (a) a Constant Conditional Correlation GARCH Approach, (b) a Dynamic Conditional Correlation GARCH Approach, and (c) a Principal Component Analysis approach. A sample of returns on the top 38 firms listed at the Karachi Stock Exchange (KSE) over the period 1998-2005 is used as a platform to evaluate the performance of these three approaches. An in-sample forecast evaluation of various approaches is employed which shows the superiority of the GARCH approach.
