Monthly based secondary data containing stock indices of these equity markets covering the period from Jan 2015 to June 2019 has been used. Analysis of study shows that Pakistan Stock Exchange is not linked with the equity markets of Bangladesh and Singapore while it is correlated with the equity markets of China, Turkey and India. Results also show that PSX has short run relationship with developing countries like China, India and Turkey.
