"Value investors will not invest in businesses that they cannot readily understand or ones they find excessively risky. Hence few value investors will own the shares of technology companies. Many also shun commercial banks, which they consider to have unanalyzable assets, as well as property and casualty insurance companies, which have both unanalyzable assets and liabilities."

That's been lost. It's a huge problem. What you have is you have the major institutions of the world all wanting to deleverage. They want to take down their assets and liabilities. What seemed so easy to borrow against a year ago now looks like rat poison to them. So they're trying to deleverage. There is only one institution in the world that can leverage up in a way that's all a countervailing force to that, and that's the United States Treasury.
