If the "edge" is ephemeral (I agree that it is), I always wonder how quant/HFT firms like Jane Street, RenTech continuously make insane profits out of such strategies.
I suppose it could be a combination of things that isn't necessarily just related to finding edge over markets. Having an entrenched market position or access to data faster perhaps?
