An increasing number of hedge funds are cashing in on the opportunities presented in the distressed mortgage-backed securities sector as banks try to offload their sub-prime exposure. Citadel snapped up for a mere $800 million E*trade’s $3 billion ABS portfolio, which comprised mortgage-backed securities and CDOs. About 60% of the assets were rated double A and higher. Along with Goldman Sachs, Waterfall Asset Management and Solent Capital, hedge fund investments in distressed mortgage-backed securities and CDOs are believed to have surpassed $10 billion since July.
