This exposure may improve rapid decision-making skills and has been linked with aggression. The same ring-to-index finger ratio, which is determined in the womb, has previously been associated with success in competitive sports. Researcher John Coates and his team reported last year that testosterone seemed to boost short term success at finance after they found City traders with higher levels of the male hormone in the morning were more likely to make an unusually big profit that day.

 

Aggression hormone

Their latest findings are based on a study of 44 men working as traders in London, some of whom earned more than £4 million a year. Over 20 months those traders with longer ring fingers made 11 times more money than those with the shortest ring fingers relative to their index fingers. This "biological" impact on success was about equal to years of experience at the job. The most experienced traders made about nine times more than the least experienced ones.

 

The scientists believe that exposure to the "aggression" hormone testosterone in the womb may have improved the traders' concentration and honed reflexes necessary to follow prices and make trades on extremely short notice.
