Warren Buffett on stock forecasters

We've long felt that the only value of stock forecasters is to make fortune tellers look good.  Even now, Charlie and I continue to believe that short-term market forecasts are poison and should be kept locked up in a safe place, away from children and also from grown-ups who behave in the market like children.
