Warren Buffett takes center stage in Omaha for Berkshire Hathaway’s annual shareholder meeting. Investors are sizing up his expected successor and getting a better sense of the conglomerate's plans. Buffett has started selling some Apple stock, citing it as a great business but potentially a lesser quality investment now. During the meeting, Buffett named Greg Abel as his successor for capital allocation decisions and revealed that the Apple stock sale was for tax reasons, not due to Apple's sales slowdown.
