Having said that, your statement above is entirely consistent with what Warren Buffett and Charlie Munger, hereinafter WBCM, say about BRKA/B when asked by potential shareholders if they should buy BRKA/B stocks. WBCM deflect by saying they bought their shares a long time ago and that the potential buyer should do their own research.
Now, a lot of things make more sense. Thanks!
