It’s often asserted (and I agree) that if you can’t identify your investing “edge,” you shouldn’t attempt active management. But then trying to figure out what edges are real and what edges are simply marketing spin is really tricky. It’s also a useful question to figure out what are the kinds of edges you can develop through practice, work, and study, and which simply depend on who you are and the organization where you work.
So I figured it’d be useful to poll people on what kinds of things seem like legitimate edges and which ones tend to be fluff, and how one might go about detecting the real from the BS.
I’ll start with some of my thoughts:
It seems to me that edges fall into a few categories: informational, process, unique risk tolerances, and execution.
So, INFORMATIONAL EDGES would be something about having unique industry knowledge, or faster (hopefully legal) access to material information,
PROCESS EDGES are things like having a better quantitative model or portfolio construction method, having a system to neutralize investor biases, or react before others can,
UNIQUE RISK TOLERANCES are generally institutional (or sometimes client type) features that allow a manager to stay in a market that others are running from (and thus buy when others are forced to sell). So endowments, for example, have longer term time horizons than individual investors and can afford to buy when others are forced to sell.
EXECUTION EDGES are about things like high frequency trading, access to dark pools, and reducing execution costs by being able to negotiate directly with counterparties or use derivatives.
This is what I can think of off the top of my head … what do others see as legitimate (or bogus) edges?
