Jane Street made it's way into today's Wall St Journal for its quantitative prowess and hiring of Math PhD's. What was stunning to hear was that their 2nd quarter profits were a record $10.3 billion, nearly double that of Goldman Sachs and Morgan Stanley (much larger firms).
They made money through extreme manipulation of the Indian stock market...when working with a market that has 422X leverage through derivatives its much easier to make money.
