Testosterone predicts profits on trading floors

Financial traders make more money when their testosterone levels are high. A study of male traders in the City of London financial district showed they made bigger profits on days when their testosterone levels were already high. The stress hormone cortisol seemed to be linked not with failure, but with uncertainty, the researchers reported in the Proceedings of the National Academy of Sciences.

Researchers tested the saliva of 17 male City of London traders for eight consecutive business days. The samples were taken at 11:00 a.m. and 4:00 p.m., before and after the bulk of the day's trading. Each trader also recorded his profit and loss (P&L). Daily testosterone was significantly higher on days when traders made more than their one-month daily average, the researchers found. "On days of higher 11:00 a.m. testosterone, traders made a P&L for the rest of the day that was significantly greater than on lower testosterone days," they wrote.

Steve - this explains why the financial markets are tanking. Too much estrogen in the environment!

All kidding aside, there is no doubt that testosterone levels in men have dipped in recent decades due to xenoestrogens in our environment, food supply, and medications. Men need to work extra hard to methylate as much estrogen as possible. We have found one beneficial, well-tolerated dietary supplement that can help with this: maca root.
