IBM has lost the confidence of one of its biggest investors, Berkshire Hathaway Chairman and CEO Warren Buffett. Buffett, who owned about 81 million shares of IBM at the end of 2016, sold off about a third of that stake in the first and second quarters of 2017, he told CNBC. "I don't value IBM the same way that I did 6 years ago when I started buying... I've revalued it somewhat downward," Buffett told CNBC. "When it got above $180 we actually sold a reasonable amount of stock."
