Is There a Better System for Predicting Commodity Prices?

We don't hedge cocoa or sugar identity. We have the faintest idea what the long-term price of oil was and there's always a better system available you can buy oil as you know for delivery a year from now or two years from now or three years from now we actually did that once Charlie didn't we it's uh some years back. The question about is maybe whether more philanthropy ought to be devoted to that relatively because of the cost but well I do a lot more than Warren does in this field and I'm frequently disappointed but monopoly has kind of and bureaucracy have kind of burnishes of act everywhere.
