The Berkshire Hathaway annual shareholder meeting, which marks the end of the "Woodstock for Capitalists" tradition, will be a challenge for the new CEO Greg Abel who took over in January. The event, long known as the "woodstock for capitalism," is expected to attract fewer than 100,000 attendees. There is some skepticism about whether Abel will be able to recapture the attention of Buffett and the late Charlie Munger.
