 Goldman had considerable advantages over its long customers.According to McLean and Nocera, there were dozens of securities being insured in the CDO - for example, another ABACUS - had 130 credits from several different mortgage originators, commercial mortgage-backed securities, debt from Sallie Mae, credit cards, etc.Goldman bought mortgages to create securities, which made it "far more likely than its clients to have early knowledge" that the housing bubble was deflating and the mortgage originators like New Century had begun to falsify documentation and sell mortgages to customers unable to pay the mortgage-holders back - which is why the fine print on at least one ABACUS prospectus warned long investors that the 'Protection Buyer' (Goldman) 'may have information, including material, non-public information' which it was not providing to the long investors.
