Berkshire Hathaway annual meeting is coming up on Saturday and will likely be a bittersweet event. As many as 30,000 investors will travel to Omaha for what CEO Warren Buffett calls a “Woodstock for Capitalists” to soak up the scene and enjoy the financial insights, humor, and life lessons offered by Buffett. For the morning session, he will be accompanied on stage by Berkshire vice chairmen Greg Abel and Ajit Jain.
