Abstract

This paper examines the dynamics of return and volatility transmission between several sectors of Pakistan Stock Exchange (PSX). We employed GARCH(1,1) model and our results demonstrate that the most influential sector regarding the return spillover is power generation and distribution sector, and regarding volatility spillover, highly influential sector is automobile sector indicating that these sectors are the main drivers of spillover effect. Whereas, the most suggested sectors for investment are Automobile Assembler and Power generation and distribution sectors, as these are least influenced by other sectors' spillover. The investors and portfolio managers can use such findings as a guideline in making a healthy portfolio resulting in reduced risk to their investment. The well-informed decisions of the investors can, in turn, facilitate the growth of economy.
