Hormones can help brokers win

Exchange traders can expect, according to a new study just then with good profits in the stock market, if their state of the male sex hormone testosterone is very high.

Increases in hormone levels, waving in the stock market gains

A strong thrust of the sex hormone testosterone could help brokers, according to British researchers to make greater profits. In contrast, the hormone cortisol is rather with uncertainty, pain and poor performance associated according to the trading floor, said researchers at the University of Cambridge in the "Proceedings" of the U.S. Academy of Sciences.

The scientists analyzed saliva from 17 London financial traders in eight days, each morning and evening to celebrate the amount of the hormones testosterone and cortisol. These were then compared with the respective financial results of days of stock market men. It noted that Professors John Coates and Joe Herbert, that stockbrokers earned with high morning testosterone levels are often more money than others. One reason could be to conjecture of Coates and Herbert, that the more successful traders felt the testosterone by a higher self-confidence and an associated higher risk. This could influence their buying and selling decisions in stock trading therefore indirectly.

"Our work suggests that their decisions by emotional and hormonal factors have influenced that have not yet been examined closely enough," said Herbert. "Any theory for decision making in the highly demanding environment of the financial trade should in future take into account the factor of hormonal changes."

While high levels of testosterone in the morning, in the case of men surveyed had mostly been an indicator of a successful business, you do not have relatively high cortisol levels can be directly equated with failure. However, climb to the production of cortisol in difficult and highly fluctuating market situations. There were these and other hormones may also influence the extent "irrational" behavior of market players, which could lead to inflation of prices or even lead to the collapse of stock values, further studies are indicated. "We still know too little about the relationship between the hormonal system and the risk-taking."
