Strategies have limits on how much money they can manage. By limits, I mean - either it's impossible to put in more (could be because there are no more counterparties to trade with above a certain amount) or it would significantly decrease performance.

And in the 30 years since closure, which has seen China, USA, and Europe boom and multiply in size, somehow the strategy still has limits?

My questions are valid, and there might be valid answers. We don't know, because nobody knows how Medallion works. All we know is that nobody else can replicate it, not even RenTech itself. Which makes asking questions very important.

Several firms have done similar things.

Do you have examples? Googling is not yielding any results for me.

Yes, it would still have limits. There are several trading / arbitrage companies that are bringing roughly the same money over the years - for the past 20 years (I used to work for one).

That being said, RenTech is indeed very interesting. For all we know, it could be a money laundering operation or something similar to Madoff's structure. Or they are just very very good, or lucky. Time will tell !
