offer a quick and relatively inexpensive way to diversify‚ the purpose of this article is to address the issue of risk reduction through international diversification. This article also provides support for the hypothesis that international market correlations increase after unexpected exogenous shocks. The implication is that diversification benefits may be reduced after such events. National economies have recently become more closely linked‚ not only because of growing international trade and investment
