Analysts at Sanford C. Bernstein & Co believe that Citigroup (C) may lose $3 billion in the third quarter. The big bank "may lose between $1.2 billion and $1.5 billion on loans to buyout firms and between $500 million and $1 billion on subprime mortgages in the three months ending Sept. 30," according to Bloomberg.
