The recipe for the perfect financial trader has been revealed by research from the University of Cambridge. Several years of experience, combined with profit sharing incentives and the right hormonal levels create the best most profitable traders, according to the study. Aggressive risk-taking, however, may not be as central to successful trading as has been thought. The males who took bigger risks were exposed to bigger losses, according to the study, and therefore were less effective in the long term than their more prudent counterparts.
