If you're a short-seller, that's a cacophony of negative reinforcement. You're basically told that you're wrong in every way imaginable every day. It takes a certain type of individual to drown that noise and negative reinforcement out and to remind oneself that their work is accurate and what they're hearing is not.

I used to think that good short-sellers could be trained like long-focused value investors because it should be the same skill set; you’re tearing into the numbers, you’re valuing the businesses, you’re assigning a consolidated value, and hopefully you’re seeing something the market doesn’t see.But now I’ve learned that there’s a big difference between a long-focused value investor and a good short-seller. That difference is psychological and I think it falls into the realm of behavioral finance.

Increasingly, the real estate developers can't get bank loans for their project financing in China. They're now going into the Hong Kong market to raise money in the bond market at very, very high rates, as high as 15, 20 percent.

What people don't realize is that China papered over its last two credit bubbles, those in 1999 and 2004. The banks were never bailed out - they just exchanged their bad loans for questionable bonds from quasi-state organizations.

Derivatives in and of themselves are not evil. There's nothing evil about how they're traded, how they're accounted for, and how they're financed, like any other financial instrument, if done properly.

What we define as a bubble is any kind of debt-fueled asset inflation where the cash flow generated by the asset itself - a rental property, office building, condo - does not cover the debt incurred to buy the asset. So you depend on a greater fool, if you will, to come in and buy at a higher price.
