OMAHA, Nebraska: Short-seller Douglas Kass, Warren Buffett's handpicked bear, raised a concern on the minds of many shareholders at the "Woodstock for capitalists" this weekend: Has Berkshire Hathaway Inc become so big that it will find it hard to grow?
Many retail investors who converged on Omaha, Nebraska, for Berkshire's annual meeting on Saturday acknowledged that its fastest growth days are likely behind it. But they said Berkshire is still a good long-term bet as faith remains in Buffett and his management team's more than 4-decade-long record of stellar returns, and the company's tentacles into many sectors of the U.S. economy.
