Jay Newman was a HUGE player in the world of distressed international debt, trading tens or hundreds of millions of dollars of low-grade government bonds for a major hedge fund including a famous (in the hedge fund world) trade of Argentinian bonds which put him in direct conflict with that nation's government...and Jay won (see second link below). He's also the author of a great first thriller novel, "Undermoney", which I encourage everyone to check out.
