Please go through the Quant thread for a better understanding of what a quant system comprises of. It is not just about universe selection. Universe selection is just one step. All steps of investing / trading can be quantified and systemised. The fundamental research of non-quantifiable nature like management quality and business quality are substituted by using some numerical proxy.
This is a complete misunderstanding. The paradigm of a quant system is that it actually can replace fundamental research completely. Whether as an investor one can follow such a system is up to to an individual, but if you have a well tested robust quant system, then fundamental research is superfluous.
