Analysis of Volatility Spillover of Portfolio Returns: Evidence From Pakistani Stock Market

Abstract

The present study attempts to model and analyze the lagged asymmetric volatility spillover effect between the high/low beta portfolio returns and the economic variables returns in case of Pakistan for the time period of July 2001 to June 2015 respectively. The lagged effect is taken to analyze and model the previous effect of the volatility spillover of the portfolio returns and the economic variables on the current volatility spillover of the respective variables respectively. The study also attempts to study the leverage effect (asymmetry) of the respective variables by employing the EGARCH model respectively. The findings of the present study indicate the significant differing volatility spillover effect of high beta portfolio returns and the low beta portfolio returns with all of the four economic variable returns respectively
