To provide a counterexample, P/NP was doing quantitative trading before RenTech. I will say that I wouldn't comment on implementation details in this industry unless I've worked at the company in question.
That's fair. It was not my intention to provide a comprehensive review of the firm's approach, but rather a quick summary that glosses over a great many details.
To address your second point, I wouldn't comment on implementation details in a company for whom I had worked.
P/NP is Princeton Newport Partners. I have a passing familiarity with that story ;)
