Warren Buffett, the billionaire chairman of Berkshire Hathaway Inc., on Thursday said the conglomerate has bought back its own stock for the first time since 2012 and has added a "little" to its already huge stake in Apple Inc.
Buffett also said investors are better off owning a basket of stocks than 30-year bonds and other fixed-income securities as a strong U.S. economy bolsters corporate profits despite higher costs from tariffs, which have also affected Berkshire.
"I don't know when to buy stocks, but I know whether to buy stocks," Buffett, celebrating his 88th birthday, said on CNBC television.
