For value investors of a certain age (e.g. mine), discovering that Warren Buffett could be wrong is like suddenly not believing in Father Christmas. This twinkly-eyed, raspy-voiced, avuncular old gentleman almost embodies Clint Eastwood crossed with a Care Bear. And nobody can hold a candle to his long-term investment record.
And yet, the rot set in (at least as far as this writer is concerned) when Buffett went from investing in private non-financial businesses to siding with the establishment, using his institutional heft to win sweetheart deals in dubious banking institutions way beyond the reach of regular Joes.
In other words, somewhere along the line he went from representing the 99% to representing the 1%. And at the first sign of trouble, he simply wraps himself up in the American flag.
