Lone Star Fund is looking to profit from the castoffs of the credit meltdown, buying billions of marked-down assets and betting on just some of them to rebound, reports the Wall Street Journal. The Dallas-based private-equity firm run by John Grayken has closed a deal on $6.7 billion in Merrill Lynch mortgage backed assets once valued at $30.6 billion. 
                                    
                                    
                                
                                
                             
                            
                            
                            
                            
                            
                                
                                
                                    
                                        With Merrill financing 75%, Lone Star has some $8 billion to continue its bargain shopping after wrapping up a $10 billion fundraising push last week for its two newest funds. 
Grayken honed his investment strategy for Lone Star "while resolving bad debt during the savings-and-loan crisis in the 1980s," the Journal notes, adding that the fund made its name by buying distressed companies and turning them around.
