Would Comcast Corp. be better off as a private company? Quite possibly yes, says Sanford Bernstein and Co. analyst Craig Moffett, who estimated in a recent research report that Comcast might be worth $50 billion more as a private company. The private investors would have to borrow about $72 billion, but they wouldn’t have to put any of their own money down. Comcast doesn’t comment on speculation, and Moffett admits he’s only speculating. He did, however, try to get Comcast Chief Executive Brian Roberts ’ attention by noting that for $50 billion, he could probably buy his own private island – maybe even Manhattan -- Miriam Hill
