To the degree in which it's possible, I'd like to know what the community believes are the objective skills/knowledge required to run a successful Quant book.
I'm not interested in strategies, obscure maths or programming languages here. I'm interested in the practical realities of successfully managing/executing a strategy - the nitty-gritty, practical knowledge outside of the strategy that is required in practice (or a huge advantage to know). Such topics are often somewhat boring and are rarely taught in school.
This knowledge will overlap significantly with that needed by traditional PMs. Let's assume this Quant PM is at a relatively small shop which does not have a large back-office or particularly sophisticated traders.
I'm looking to fill in any potential missing areas of knowledge. I imagine other traditionally trained quants may benefit from this discussion.
Some possible suggestions:
The ins and outs of Securities Lending and traditional services offered by PBs
Marketing of strategy (internally, but perhaps formally to outside investors)
Regulatory Environment / Pending Regulation
Deep understanding of 'Liquidity' (beyond simply historical ADVs, this may include how crowded you believe your trade to be)
Algorithmic Execution (what is the best trading approach given strategy's alpha decay? Should you always be a liquidity demander?)
