Investing.com - Warren Buffett said Berkshire Hathaway (NYSE:BRKa) has bought some 120 mn (NASDAQ:Apple) shares this year.
Buffett told CNBC Berkshire's Apple stake of 133 mn shares is worth about $17 bn, the fund's second-biggest holding.
Buffett also told CNBC Monday he believes U.S. stocks are not in "bubble territory."
"Apple strikes me as having quite a sticky product," Buffett said, adding CEO Tim Cook has done a "terrific job."
Buffett said Berkshire had spent some $20 bn on stocks since just before the Nov. 8 U.S. election.
He said U.S. stocks are cheap with interest rates at current levels.
However, he also said U.S. stocks could possibly "go down 20% tomorrow."
Buffett said (NASDAQ:Kraft's) rejected bid for (NYSE:Unilever) was never mean to be hostile.
Berkshire is a major shareholder in Kraft.
