Definitely VTSMX! The results for the second quarter will boost VTSMX way beyond VGTSX. The reason for this will be all those juicy Euro dollars will be rolling into the quarterly reports on this side of the world.
This trend will continue through the end of the year. VTSMX will be the beneficiary of all those lucrative IBM, MSFT, GE, etc. reports. Stay on this side of the globe, lots of danger in Asia and Europe from now on.
