“You don’t really care until you care” (meaning until you have a position) - Anonymous Trader

How true ? A quant might built a SVI parametric stochastic vol model and calibrate the parameters , produce beautiful graphs and sleep peacefully at night assuming that one has created a fascinating fit. Little does it matter in real world. If the same quant were asked to trade S&P options , then probably the whole model development might be approached from a different perspective. . So, the moot question is Do quants make better traders, as they probably can think more than trust the gut !! Should quants aspire to be traders ?
