Diversification, Schmversification: All Correlations to 1.0(-ish)

Good set of graphs in a new paper showing how correlations have increased across equity markets in recent decades. In each graph the top line is the correlation with developed markets, the middle line is with developed & emerging combined, and the bottom line is correlation with emerging markets alone. The trend is steadily higher for most countries, with a few seeing serious spikes toward unity.
