   I am reminded of Hari Seldon's Psychohistory in this regard. It modeled the whole of a human society, and could make acurate predctions of large groups of people. But, that's fiction. The reality is that unforseen random events cause sharp changes of direction, in society and the stock market. You can't predict randomness - otherwise it's not randomness.
