A lot of style purists want to have small cap foreign funds. But (the category) still in its infancy. I'm still not completely sure you need one in your portfolio. This is something that is relatively new. You have to be very careful when you choose a fund.
There are a lot of good companies outside the U.S. and it's good to have exposure to them,
I'm not sure the funds have proven themselves, ... I'd really be hesitant for anybody to take a look at them.
