This is an insightful book that makes a great case for the importance and need for short selling. It chornicles the bias toward optimism in the marketplace and this is especially relevant after we have had two bubbles burst in the last 10 years associated with excessive optimism. This is a nice compliment to the work that has been done in regard to capital market efficiency, etc. I recommend this to intermediate to advanced financial-minded people who want a different perspective on pricing and investor motivation.
