| Abstract: | A stylized fact in the portfolio diversification (hereafter as: div.) literature is that diversifying (here as: div-g.) across countries is more effective than div-g. across industries in terms of risk reduction. However, since the mid-1990s, this no longer appears to be true. This paper explores if this change is driven by global integration, and likely to be permanent, or if it is a temporary phenomenon associated with the recent stock market bubble. The results point to the latter hypothesis. In the aftermath of the bubble, div-g. across countries may therefore still be effective in reducing portfolio risk. |
