His call to buy America is too early at best. But I think saying he's done is a little early too. His recent buys(GS, GE, harley-davidson,etc.) at Berkshire are almost all preferred shares or bonds that pay at least 10%. Unless these companies go bankrupt, his investments will have decent returns. Maybe that's why he sold some stocks in the fourth quarter -- simply to rotate the money into safer investments of preferreds and bonds.
