I know a few people who work at RenTech. I would be very surprised if the operation turned out to be fraudulent. It certainly could be, but I very much doubt it.
If you have your ear to the ground you can find many proprietary trading firms which have similar or even superior returns. It's much harder to find a fund deploying similar strategies at the same capacity.
As a corollary, every single new hire at the firm is expensive in more than the traditional ways. They only have so much room in Medallion, and so they tend to be both extremely secretive and extremely protective when hiring. They've lessened up on that somewhat recently, but it's still there.
