Story about a Quant's life, this a math smart kid, Peter Muller, who worked for a risk analysis firm called Barra Inc in Berkeley, California, and later joins Morgan Stanley to help set up its Quant trading business. "Pairs trading" is one of the strategies Quants have used in the past in which two stocks which have a strong historical relationship provide clues as to how to short one and by another betting that the historical relationship will assert itself. "Statistical Arbitrage" is a more complex version of this and Muller's specialty was in this field at Morgan Stanley's Process Driven Trading Group (PDT). This Group produced profits from trading of about $3.5 billion in ten years upto 2006. This group now contains about $6 billion of Morgan Stanley's own money and accounted for 7.2 % of Morgan Stanley's net income with profits of $540 million in 2006. In the two weeks prior to August 9, Morgan Stanley's PDT lost about $500 million as the mortgage crisis broke out and put a wrench in the normal workings of the Quant's strategy and the fact that there are so many Quants operating with computerized trading may have added to the problem. the PDT has since recovered some of its losses. And its by no means certain that this has shaken Morgan Stanley's continued pursuit of income from Quant trading operations. The story thats told about Peter Muller is interesting as he tries everything to find happiness leaving his job for a while and playing his own music on albums and in the streets of Barcelona and New York city subway stations to soothe his restless soul and still comes back to his old job. All this happens while he is still 43.
