IBM  whose full name is International Business Machines Corp  accounted for most of the stock sales that  Buffett  and  his  deputies Todd Combs and Ted Weschler made in the quarter.
In May   Buffett  revealed  he  had begun selling IBM  telling CNBC  he  did not value Big Blue as highly as  he  did six years earlier when  he  started buying.
âIBM is a big strong company  but theyâve got big strong competitors  too â  he  said.
The IBM investment had been viewed as a surprise  given the 87-year-old Buffettâs resistance to investing in technology companies and businesses  he  found harder to understand.
