'Thinking like a trader' may diminish emotional reaction and aversion to loss

17.03.2009
The late 1990s saw the rise not only of the NASDAQ, the Dow, and the S & P 500, but also of amateur traders—individuals not formally trained to work in the unpredictable world of the stock market—to complement seasoned professionals.

Beyond the differences in their credentials, a study led by researchers at the California Institute of Technology (Caltech) and New York University suggests that taking the perspective of a professional trader may alter the emotional reaction to losing money and result in different choices.

Their findings appear in the latest issue of the Proceedings of the National Academy of Sciences (PNAS).

The work examined correlations between loss-averse behavior and physiological arousal while subjects were asked to either focus on individual choices or take a portfolio perspective ("think like a trader"), which was hypothesized to reduce the emotional reaction to potential losses. The researchers combined methods from psychological and economic research, providing a detailed picture of how people make choices and how their perspective changes the mechanisms of decision-making.

Specifically, they asked subjects to complete a series of 140 choices between a risky gamble and a guaranteed amount of return. Subjects completed two sets of choices—one set using a strategy emphasizing each choice in isolation and one set using a strategy emphasizing each choice as one of many. Choices in isolation are analogous to those an amateur trader might make; choices made as one of many are akin to decisions a professional trader would implement because they simulate management of a diversified portfolio.

When making choices in isolation many of the subjects were loss averse. That is, they were more concerned about avoiding financial losses than in making financial gains. However, when subjects were asked to make choices using a strategy that emphasized these choices' larger context as one of many decisions—such as the decisions one would make in managing a portfolio of investments—the vast majority of participants were less loss averse.

In an effort to examine emotional factors that may coincide with the behavioral expression of loss aversion, the researchers measured changes in subjects' skin conductance due to increased sweating in response to learning the outcomes of their decisions. The results for choices made in isolation showed that subjects sweat significantly more, per dollar, to losses than gains. This "over-arousal" to losses was correlated with behavioral loss aversion, which suggests a specific role for emotions in choice. However, when subjects made decisions using the "portfolio" strategy mentioned above, the over-arousal effect disappeared—average levels of sweating per dollar were about the same for gains and losses.

The findings could be relevant to drawing distinctions between amateur and professional traders because the professionals are trafficking in portfolios and amateurs are not. Specifically, the findings support the conclusion that professionals have learned not just facts about investments, but also strategies for limiting the normal emotional response that might prevent amateurs from making the same decisions given the same information.

The research was conducted in the laboratory of NYU's Elizabeth Phelps, one of the study's co-authors.

"These results highlight how a simple shift in perspective can influence both the emotional reaction to a financial decision, and the decision itself," commented Phelps, who is professor of psychology and neural science at NYU.

Peter Sokol-Hessner, the study's lead author, added, "Though on average we may dislike losses more than we like gains, both in our behavior and in our physiological responses to them, it seems we have the power to change that."

Im Focus: Novel silicon etching technique crafts 3-D gradient refractive index micro-optics

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.

Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...

Im Focus: Quantum Particles Form Droplets

In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.

“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...

Im Focus: MADMAX: Max Planck Institute for Physics takes up axion research

The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.

The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...

Im Focus: Fraunhofer ISE Develops Highly Compact, High Frequency DC/DC Converter for Aviation

The efficiency of power electronic systems is not solely dependent on electrical efficiency but also on weight, for example, in mobile systems. When the weight of relevant components and devices in airplanes, for instance, is reduced, fuel savings can be achieved and correspondingly greenhouse gas emissions decreased. New materials and components based on gallium nitride (GaN) can help to reduce weight and increase the efficiency. With these new materials, power electronic switches can be operated at higher switching frequency, resulting in higher power density and lower material costs.

Researchers at the Fraunhofer Institute for Solar Energy Systems ISE together with partners have investigated how these materials can be used to make power...
