NEW YORK (Reuters) - Hedge fund billionaire John Paulson's firm took a stake in Citigroup
Paulson, whose firm Paulson & Co bet against financial companies and the housing market before the credit crisis, also dissolved his stakes in Petro-Canada, Humana Inc
Besides Bank of America, Paulson cut his stake in JPMorgan Chase & Co
Investors scrutinize Paulson & Co's holdings since the firm reaped big gains by betting that the U.S. mortgage market would collapse in 2007. It also bet that financial services companies would tumble last year.
