Advanced Maths Win Wall Street

A view of what used to be called 'rocket scientists' in Wall Street.  I recall going to the Santa Fe Institute and hearing a talk about this phenomenon,  just before the crash.   Now its math, big data and analytics.  Its not that I do not believe in these methods, I just look at the predictive value with caution.  Note something new here, the use of forward-looking, unstructured data analysis to look for causal triggers.    As opposed to quant forecasting.
