Goldman’s own clients who bought them, however, were less fortunate.

Pension funds and insurance companies lost billions of dollars on securities that they believed were solid investments, according to former Goldman employees with direct knowledge of the deals who asked not to be identified because they have confidentiality agreements with the firm.

Goldman was not the only firm that peddled these complex securities — known as synthetic collateralized debt obligations, or C.D.O.’s — and then made financial bets against them, called selling short in Wall Street parlance. Others that created similar securities and then bet they would fail, according to Wall Street traders, include Deutsche Bank and Morgan Stanley, as well as smaller firms like Tricadia Inc., an investment company whose parent firm was overseen by Lewis A. Sachs, who this year became a special counselor to Treasury Secretary Timothy F. Geithner.
