Re: Emerging Markets
My guess is diversification. From what I know emerging markets have one of the lowest + correl with the US stocks when comparing it to other equity investments. I believe the index is trading above historical highs in terms of valuation but I suppose some could argue that this is where the growth will be in the future. If you maintain a small long-term position you might see the benefits of both.
