Prof. Aswath Damodaran on the Kraft-Heinz saga and the dangers of blindly following the Oracle of Omaha:

It is human to err … Buffett has been open about his mistakes, and how much they have cost him and Berkshire Hathaway shareholders. He has also been candid about his blind spots, which include an unwillingness to invest in businesses that he does not understand, a sphere that only grows as he gets older and the economy changes, and an excessive trust in the managers of the companies that he invests in. … The fault, in my view, is not with Buffett, but with the legions of investors, analysts and journalists who treat him as an investment deity, quoting his words as gospel and tarring and feathering anyone who dares to question them.
