I find the parallels between how some investors refuse to recognise the trends and our reaction to some of our environmental challenges very powerful. There is an unwillingness to process unpleasant data.

Think how weird profit margins are: We've got high unemployment and financial crises - and world record profit margins. People think the American market is very cheap. We don't. The market quite incorrectly gives full credit to today's earnings.

You don't actually find a strong correlation between- top-line GDP growth and making money in the market. It- it seems like you should. The fastest-growing countries should give you the highest return. They simply don't. But, there's only four of us- that- that believe that story. Everyone else in the world believes that if you grow fast like China, you'll outperform in the stock market.

Modern agriculture has been accurately described as a way of turning oil into food. As the price of oil continues to rise, so will the price of food.

Profit margins are probably the most mean-reverting series in finance, and if profit margins do not mean-revert, then something has gone badly wrong with capitalism. If high profits do not attract competition, there is something wrong with the system and it is not functioning properly.

I like to be right. I try not to miss the big ideas, forget the little ones, and try to get them right. End of job description.

Equities are boring; bonds are disgusting.
