If you are looking for a good fund for this corner of your portfolio, you might want to consider Eaton Vance Structured Emerging Mkt (EAEMX). There is also a much cheaper version (EITEX), but it is open just to folks with a financial advisor.
It is a mechanical fund. Here is how their strategy works (as far as I understand it):
The end result is as follows:
In essence they maximize the positive effects of diversification and tax efficiency, which are very stable effects. They are mathematically provable :-) The real time results confirm the theory as this has been one of the best performing Em. Markets funds with the lowest standard deviation and best tax efficiency. No-one knows what the future holds, but there is a good chance that this will continue to be the case.
I don't own it currently because I don't like the high fees, but the strategy makes so much sense that I might end up buying into it.
