I don't think it's investors feeling grouchy as much as Wall St. reporters who seem unable to write in anything other than garbage language. BH management do not concern themselves with short- or medium-term performance much; eyes fixed firmly on the long term. This is utterly foreign to most finance journos.

If you read Buffet's letter to investors, you'll see him explicitly saying that some years are bound to be less than wonderful, but that over the long run, envestment in BH will do well.
