Global stock market landscape: an application of minimum spanning tree technique
by Kusdhianto Setiawan
International Journal of Operational Research (IJOR), Vol. 20, No. 1, 2014

Abstract: This paper analyses the degree of integration among 22 stock markets from Asia Pacific, Europe, and the USA from 2000 to 2010. Unlike previous literature on capital market integration, this paper used the minimum spanning tree technique to measure the degree of integration of the markets simultaneously or on a multilateral basis (on a set of markets) instead of on a bilateral basis (a relationship between two markets). A measure of consistency of the minimum spanning tree (MST) structure over observation periods was developed. Findings show that the degree of integration is dynamic but tends to increase (markets are becoming more integrated). However, the stock market integration is incomplete; market segments based on geographic proximity with an internationally diversified portfolio offer gains in a strongly integrated world financial market.
