The list of ETFs is growing every day, but for now, many of the best choices for these sectors can be addressed with mutual funds, namely the Oakmark International Small Cap I ( OAKEX) and the Wasatach Micro Cap Fund ( WMICX), both found on the Forbes Honor Roll.
That excludes institutional-only funds and those that are closed to new investors, like the excellent Oakmark Select (12% a year since March 2000 and 17% a year since 1997).
