We calculated the correlations between each pair of global country ETF for the period April and May 2010. It is a sea of green and red. Please click to enlarge:
The overwhelming majority of these ETFs are highly correlated, either positively or negatively (FXP, the Chinese bear ETF). I have never seen these kind of high correlations.
For diversification, there were no really good uncorrelated EFs. The best pairs of ETFs during this time frame were:
- THD (Thailand) and all others
- FXI (China bull) and FXP (China bear) and EWM
- EWM (Malaysia with EWI (Italy) and EWK (Belgium)
However, some of those values are still as high as 0.75.
