It's probably pretty easy to keep the returns on a pot as small as $10bn sweet if you just reserve all your best alphas for that fund. There are proprietary trading firms trading pots that size for a single shareholder.

What I've been told is that Rentech also effectively use their public funds as a source of revenue to juice development of proprietary platform, so some of it is business cunning rather than a hard technical edge.

They were also got on the quant train very early.

To even have those ‘best alphas’ in the first place and then select them in advance for your best fund is the impressive part. The returns are insane even if the fund is capped.

They were successful long before they had those public funds though.
