i will just say this - rentech did make it big but not in the "PR" way they would like for you to think they did. they paint an image of mathematically genius etc.
'my opinion' is it was all done with relationships, under the table deals, bribery, possibly some extortion and certainly insider information at the exchange levels.
i was trading directly against their positions around early 2000 from an office in chicago in the cme building. they took on some prop traders who were not profitable and suddenly these guys were rolling in money. these guys were being fed position sizes, price levels of stops and customer id's again "in my opinion".
can i prove my above statements, no more than you can prove anything that goes on within the exchanges and outside firms relationships. but i am sure i know exactly how it all worked cause they tried to recruit one of our top guys who was making money on his own. he didn't go over cause we all kept thinking they would get busted.
too big to fail comes to mind, with a wall of protection from paid off regulators.
The problem with your theory is Jim Simons IS a mathematical genius- actually world class--- that fact cannot be argued.
We are not dealing with some toady who pretends to know things. He really does know things.
