Finger length may predict financial success

WASHINGTON – The length of a man's ring finger may predict his success as a financial trader. Researchers at the University of Cambridge in England report that men with longer ring fingers, compared to their index fingers, tended to be more successful in the frantic high-frequency trading in the London financial district.

Indeed, the impact of biology on success was about equal to years of experience at the job, the team led by physiologist John M. Coates reports in Monday's edition of Proceedings of the National Academy of Sciences.

The same ring-to-index finger ratio has previously been associated with success in competitive sports such as soccer and basketball, the researchers noted.

The length ratio between those two fingers is determined during the development of the fetus and the relatively longer ring finger indicates greater exposure to the male hormone androgen, the researchers noted.

Previous studies have found that such exposure can lead to increased confidence, risk preferences, search persistence, heightened vigilance and quickened reaction times.

In a separate study last year, Coates and colleagues reported that the hormone that drives male aggression and sexual interest also seemed able to boost short term success at finance.

They studied male financial traders in London, taking saliva samples in the morning and evening. They found that those with higher levels of testosterone in the morning were more likely to make an unusually big profit that day. Testosterone, best known as the male sex hormone, affects aggression, confidence and risk-taking.

In the new study, the researchers measured the right hands of 44 male stock traders who were engaged in a type of trade that involved rapid decision-making and quick physical reactions.

Over 20 months those with longer ring fingers compared to their index fingers made 11 times more money than those with the shortest ring fingers. Over the same time the most experienced traders made about 9 times more than the least experienced ones.

Looking only at experienced traders, the long-ring-finger folks earned 5 times more than those with short ring fingers.

While the finger ratio, showing fetal exposure to male hormones, appears to signal likely success in high-actively trading that calls for risk-taking and quick reactions, it may not indicate people who would do well at other sorts of financial activities, the researchers said.

Some traders require additional skills on dealing with clients and sales workers.

And the advantage may even reverse for some, Coates team said, such as traders taking a more analytical and long-term approach to the markets.

One study, which looked at average finger ratios in university departments found that faculty from math, science and engineering exhibited longer index finger ratio, rather than ring finger, they noted.

Dr. Peter Hurd a psychologist at the University of Alberta, and his graduate student Allison Bailey, have found that a man's index finger length relative to ring finger length can predict how physically aggressive that man might be. This has been known for more than a century; researchers recently found a direct correlation between finger lengths and the amount of testosterone that a fetus is exposed to in the womb. The shorter the index finger relative to the ring finger, the higher the amount of prenatal testosterone, and--as Hurd and Bailey have now shown--the more likely he will be physically aggressive throughout his life. Women do not have this feature. "More than anything, I think the findings reinforce and underline that a large part of our personalities and our traits are determined while we're still in the womb," said Hurd. Hurd and Bailey's research was determined from surveys and hand measurements of 300 U of A undergraduates. In their study, they found there were no correlations between finger lengths and verbally aggressive, angry, or hostile behaviors, but there was to physically aggressive behavior. Hurd is conducting ongoing research on hockey players' finger lengths and cross referencing the results with each player's penalty minutes as well as a similar study showing that men with more feminine finger ratios are more prone to depression; a paper on this will be published later this year in Personality and Individual Differences. "Finger lengths explain about five per cent of the variation in these personality measures, so research like this won't allow you to draw conclusions about specific people. For example, you wouldn't want to screen people for certain jobs based on their finger lengths," Hurd said. "But finger length can you tell you a little bit about where personality comes from, and that's what we are continuing to explore."

Interesting, watch men's fingers.
