International indexing as a means of portfolio diversification

Abstract

Global investing offers investors a larger pool of investment opportunities and tremendous diversification. However, despite the increased integration of world economies, there are still important variations among overseas capital markets. Complexities of overseas investing can often ensnare even the best active asset managers. International indexing is an option to overcome the difficulties of global investing. This study considers international indexing as a means of portfolio diversification. Performances of 15 international indexes are evaluated using monthly return data from 1998 through 2002. Returns are measured against ISE-100 Index (Istanbul Stock Exchange-100 Index) returns. The results of the study suggest that international indexing does not offer superior returns compared to the ISE-100 index. © 2005 Taylor & Francis.
