There is a third way.Quote from sle:
Personally, I'd feel that it's exactly the opposite. The bigger is the capacity, the less of an alpha and more of a beta trade it becomes. There are edges out there that exist for decades simply because of capacity constraints and are simply waiting for someone to harvest them. If anything, ability to generate alpha negatively correlates with size and at some point any sort of fund trading boils down to large beta bets, sometimes smart and sometimes not so much.
I'm thinking of some of the larger carries that scale into the hundreds of millions. Basically no beta risk. Some sensitivity to rates.
Opportunity to run the constrained stuff out of the same book, against held inventory.
