What they found
The authors wired ten professional FX and derivatives traders at a Boston firm with sensors measuring skin conductance, heart rate, blood volume pulse, and other physiological signals during live trading. Significant physiological responses occurred around market events such as volatility spikes and trend reversals, even in the most experienced traders, showing that emotion is part of professional decision making rather than absent from it. Less experienced traders showed larger responses than veterans, suggesting that experience dampens but does not eliminate the emotional reaction.
What you can use
- Even professional traders have measurable physiological reactions to market events; the goal is not to feel nothing but to keep it from driving decisions.
- Experience reduces the intensity of emotional reactions; part of what a veteran has learned is physiological regulation.
- Trend reversals and volatility spikes are the events most likely to hijack your judgment, which is when rules help most.
Caveats
Ten traders at one firm; small sample and exploratory. Correlational, and cannot say whether the reactions helped or hurt performance. Free NBER version exists.
