The Rule of the Quants (BBC News)

A broker and a computer programmer
Mathematicians and their trading programs are increasingly taking the
place of professional investors in financial centres across the world



Quant trading: How mathematicians rule the markets

Trading floors were once the preserve of adrenalin-fuelled dealers aggressively executing the orders of brokers who relied on research, experience and gut instinct to decide where best to invest.


Long ago computers made dealers redundant, yet brokers and their ilk have remained the masters of the investment universe, free to buy and sell wherever they see fit.
But the last bastion of the old order is now under threat.
Investment decisions are no longer being made by financiers, but increasingly by PhD mathematicians and the immensely complex computer programs they devise.
Fundamental research and intuition are being usurped by algorithmic formulae. Quant trading is taking over the world's financial capitals.
