Practical Examples

1. Michael Burry's bet against subprime mortgages

   Dr. Michael Burry realized that the booming housing market was built on unsustainable subprime loans. He created credit default swaps to bet against these loans, which seemed nonsensical to Wall Street, but paid off massively when the market crashed.

2. Steve Eisman's skepticism of the banking industry

   Steve Eisman doggedly investigated mortgage-backed securities and realized banks were ignorant of the risks inside their own products. His outspoken criticism and short positions on banks were initially mocked but later vindicated.

3. Greg Lippmann's role as a trader at Deutsche Bank

   Lippmann recognized the vulnerability of subprime mortgage bonds and sought out investors willing to take the unpopular short side of the trade. He became a key broker between bearish investors and banks that were still pushing mortgage products.

4. The mis-rating of CDOs by rating agencies

   Rating agencies stamped risky mortgage-backed products as AAA, misleading investors about their safety. This example shows how complacency and flawed models contributed to systemic risk and the crisis.

5. Cornwall Capital's outsized gains from small bets

   A small hedge fund, Cornwall Capital, started with $110,000 and turned it into millions by making smart, asymmetric bets against the housing market. Their story illustrates how analysis and contrarian thinking can create massive opportunities in chaotic markets.

6. Wall Street's disconnect from Main Street

   Bankers and traders were out of touch with the realities of the housing market, incentivized only to close deals and not to assess actual creditworthiness. This disconnect fueled the housing bubble and eventual collapse.

7. The perverse incentives in mortgage origination

   Mortgage brokers and lenders made loans to unqualified borrowers, knowing they could sell those loans off, pushing toxic assets into the financial system. The example underscores how short-term profit motives compromised long-term stability.

8. Investor confusion over complex financial instruments

   Most of Wall Street failed to understand the inner workings of CDOs and CDSs, dismissing the warnings of a few. The opacity and complexity prevented meaningful risk assessment.
