I checked my Oakmark prospectus and for laughs went to the Morgan site and randomly checked about 8 different funds, among them Growth, Aggresive, and balanced - no Index funds Not one mentioned a dollar amount that prohibited the fund from investing. They did however state what protion of the fund , be it 75% etc would be invested in equities. My Oakmark fund makes no mention of a pric, only stocks that are deemed undervalued, but never a price barrier.
