I read somewhere that there is an investment fund in the USA which in its trading decisions uses physical laws of hydrodynamics. I asked my physicist friend, on the account of what is really in hydrodynamics there are laws that allow you to analyze market quotes. He said there are different methods analysis, but could not give a definite answer. What do you think about this? Is that marketing ploy? Or in hydrodynamics or related disciplines do have methods and algorithms which can be extrapolated to analyze market quotes (for example, stocks). As far as I understand there is the main idea in the randomness of the process, that for example as the water in the river flows and has random swirls, so market quotes can fluctuate in this style.
I understand that here a contingent of people who are not strongly connected with finance, but I'm more interested in the physical side of the issue
