He found that traders with a longer ring fingers, and therefore higher prenatal testosterone, made on average six times the profits of traders exposed to low levels of the hormone, and tended to remain traders for longer.

Previous studies have also suggested a link between a low index-to-ring-finger ratio and autism, and better sporting ability.

“This study provides evidence for human beings of what we know from studies of animals, that exposure to sex hormones early in life predisposes the nervous systems and resulting behavior to develop in certain ways,” says Bruce mcEwen of the Rockefeller University in New York. “In this case the development of the risk taking, visual-motor skills, etc that make for success in this kind of rapid stock trading.”

Finger Length Key to Female Athletic Potential

“Previous studies have suggested the change in finger length was due to changes in testosterone levels in the womb,” he said.
But he said the unit had found in a separate study of twins that finger length was largely inherited, possibly explaining why sporting parents often have sporting children.
“We found that finger length was 70 percent heritable with little influence of the womb environment,” he said.
“This suggests that genes are the main factor and that finger length is a marker of your genes.”
