How relevant is thinking of physics in Quant trading
Hi,
I am a computer science graduate, who left physics in high school, I used to be good at it but still didn't really scratcch beyond the surface of special relativity. Recently I was talking to a physics + CS grad working in quant in commodities trading and he told me that most of his alphas come from some modification of applying his understanding of space time to market dynamics. That left me curious, how direct is the application of such thinking when formulating alphas ? Do some model dynamics in quantum / relativistic physics really translate directly to the stock market that well ? Thanks !!
